Hi, everyone. Thanks for joining us today. This was a good quarter for our product and business. There are now more than 3.5 billion people who actively use one or more of our services. I'm excited about our product roadmaps ahead. I want to start today by discussing some of the themes that we're seeing in our major efforts around creators, commerce and the next computing platform. Each of these areas is important and is going to unlock a lot of value on its own. They're also building blocks for the future of the internet and the future vision for our company. I'll discuss that as well. First, let's talk about creators.
Now, we want our platforms to be the best place for millions of creators to earn a living. If we can do this, then our services will also have the best content across many different types of media, from text and photos to audio, gaming and video. Video, in particular, is becoming the primary way that people use our product and express themselves. I know this is a theme that we've been talking about for a few years now, but we've been executing on this for a while, and video has steadily become more important in our product. Video now accounts for almost half of all time spent on Facebook, and Reels is already the largest contributor to engagement growth on Instagram.
Across all forms of video, short-form video like Reels is growing especially quickly. We're very focused on making it easy for anyone to create video and then for those videos to be viewed across all of our different services, starting with Facebook and Instagram first. People like to watch videos recommended by our personalized algorithms. This gives creators a good way to reach new people who don't follow them yet, and this is also a good complement to our social Feed, and it's an area where our progress in AI is gonna make the experience a lot better in the coming months and years. On-demand video, like in Facebook Watch, is also growing quickly and is now growing faster than other types of video or content in News Feed. We're building a number of new video monetization tools for creators. They can get compensated for making great content.
So for example, last year, people sent more than $50 million of Stars to game stream creators going live on Facebook alone, and now we're extending Stars so fans can send them to any creator during on-demand video as well. I also wanna call out live video for one moment. This is a smaller % of our overall video on our services, but it's some of the most unique content and gives creators a way to build community and engage with their followers. We're also focused on developing monetization tools like live breaks for mid-roll ads and live shopping so creators can make a living and engage their communities more deeply in commerce with their content.
Overall, there's a lot more to do here, and as it becomes the majority of engagement across our services in the coming years, we're gonna continue to focus on this. We're also focused on other types of creators beyond video, and some of the most interesting emergent behavior that we're seeing is creators using a lot of different types of content to engage their communities. We've launched live audio rooms this quarter as well as podcasts. We also launched Bulletin, our publishing and subscription service for writers and with features to help them find and grow their audiences, including integrations with Groups, Facebook Live and live audio rooms.
To help grow the creator economy overall, we're gonna keep our creator tools free to use through 2023. We recently announced that we're investing $1 billion in creators across Facebook and Instagram. I'm optimistic that creators will get more opportunities to do the work that they want, and that's gonna lead to people hearing lots of new voices across our different services. The second area that I wanna talk about today is commerce. Our goal here is to create better experiences for people interacting with businesses and to help businesses grow even more on our platform.
Our approach is to work our way down the stack, and build world-class services at every layer of commerce, starting from discovery, at the top of the stack, all the way down to payments. You know, just like we want to be the best place for millions of creators to make a living, we also want to be the best place for businesses to grow as well. We started here by building world-class ads tools to help businesses reach potential customers and help people discover new products and services that they might like. What we found is that when these ads link off-site, you often land on a webpage that's not personalized or not optimized, or where you have to reenter your payment information, and that's not a good experience for people and it doesn't lead to the best results for businesses either.
Our next phase here is focused on building out shops, marketplace, and business messaging in WhatsApp and Messenger, to create more native commerce experiences across our apps. There's a lot of work here to do to support all of the business tools natively, that already exist for the web. As we bring more of this online and enable more of this, it's gonna create a superior consumer experience and it's gonna convert better for businesses. This is gonna lead to more businesses investing in building out their presences across our services, and that will lead to even more diversity of products for people to discover and interact with. This is a long-term strategy. It's gonna take a while before it's meaningful, especially given the scale of our ads business already, but I'm confident that it's the right long-term bet and product direction.
As we work our way down the stack, from discovery and ads to native commerce storefronts, we're also making progress on payments at the same time. WhatsApp payments are now available to everyone in Brazil as well as India. Lots of people are already using this as a simple and secure way to send money to friends. We're adding new payments features in Messenger in the U.S. like QR codes. We also just announced that we're making Facebook Pay available outside of our apps for the first time, which means that you're gonna start seeing it as a checkout option on the web, and especially in web views that you see within our app after clicking on ads or other business content. Commerce experiences are now accessible across most of our services, and we have a full roadmap of deeper integrations that I'm excited about in the months ahead.
The third area I want to talk about is building the next computing platform. We're continuing to invest very heavily in building technology and products to deliver a full sense of presence. This is gonna be critical for unlocking the next generation of social internet services. Quest 2, in particular, continues doing well and it keeps getting better monthly as we release regular software updates, including most recently our Passthrough API so developers can start building mixed reality experiences on Quest. The range of content and experiences that we're seeing keeps broadening as well to the point where there are a lot of popular virtual reality experiences beyond games at this point.
The most popular apps on Quest are social, which fits our original thesis here that virtual reality will be a social platform, and that's why we're so focused on building it. We're also seeing compelling use cases in other forms of entertainment as well as work, creativity, and fitness. Looking ahead here, the next product release will be the launch of our first smart glasses from Ray-Ban in partnership with EssilorLuxottica. The glasses have their iconic form factor, and they let you do some pretty neat things, so I'm excited to get these into people's hands and to continue to make progress on the journey towards full augmented-reality glasses in the future.
The areas that I've discussed today, creators, commerce, and the next computing platform, they're each important priorities for us and they're each gonna unlock a lot of value on their own. Together these efforts are also part of a much larger goal to help build the metaverse. I'll be sharing a lot more about this in months ahead, so I wanted to discuss this now so you can see the future that we're working towards and how our major initiatives across the company are gonna map to that. What is the metaverse? It's, you know, it's a virtual environment where you can be present with people in digital spaces. You can kind of think about this as an embodied internet that you're inside of rather than just looking at.
We believe that this is going to be the successor to the mobile internet. You're gonna be able to access the metaverse from all different devices and different levels of fidelity, from apps on phones and PCs to immersive virtual and augmented reality devices. Within the metaverse, you're gonna be able to hang out, play games with friends, work, create, and more. You're basically gonna be able to do everything that you can on the internet today, as well as some things that don't make sense on the internet today, like dancing. You know, the defining quality of the metaverse is presence, which is this feeling that you're really there with another person or in another place.
Creation, avatars, and digital objects are gonna be central to how we express ourselves, and this is gonna lead to entirely new experiences and economic opportunities. I think that overall this is one of the most exciting projects that we're gonna get to work on in our lifetime. It's gonna take a lot of work and no one company is gonna be able to build this all by themselves. Part of what I've learned over the last five years is that, you know, we can't just focus on building great experiences. We also need to make sure that we're helping to build ecosystems so millions of other people can participate in the upside and opportunity of what we're all creating. There are gonna need to be new protocols and standards, new devices, new chips, new software from rendering engines to payment systems and everything in between.
In order for the metaverse to fulfill its potential, and we believe that it should be built in a way that is open for everyone to participate. I expect that this is gonna create a lot of value for many companies up and down the stack, but it's also gonna require a very significant investment over many years. I see our focus here as a continuation of our work to build technology that brings people together. In many ways, the metaverse is the ultimate expression of social technology. Some of the experiences that I've dreamed of building since well before I started Facebook are only starting to become possible now.
If you look at the investments that we've made over the years, you can see this vision gradually starting to come to focus and you can see why we're so excited about it. In addition to being the next generation of the internet, the metaverse is also gonna be the next chapter for us as a company. In the coming years, I expect people will transition from seeing us primarily as a social media company, to seeing us as a metaverse company. There's a lot that we need to do to get there, and there are gonna be many exciting milestones along the way, including some which we'll share in the months ahead.
In the meantime, I just wanna take a moment to thank everyone in our community, all of our partners and employees, and everyone who has supported us so far. I continue to be grateful to be on this journey with all of you. Now, here is Sheryl.
Hi everyone. Thanks, Mark. I hope you're all safe and healthy. This was a really strong quarter for our business. Our total revenue for Q2 was $29.1 billion, which is a 56% year-over-year increase. We've seen strong growth in all regions and across most verticals. Our strongest verticals are those that have performed well throughout the pandemic, including e-commerce, retail, and CPG. We're also seeing continued recovery in others, like travel, that were hit hard by COVID. Our performance continues to be driven by the ongoing digital transformation. This has accelerated during the pandemic and our long-term investments in tools and products to help businesses make the shift online.
Not long ago, it was much harder and much more expensive for businesses to create a digital presence, take orders online, and reach customers remotely. Our tools and products make these things easier and more accessible. Businesses and creators can set up pages, profiles, and shops on Facebook and Instagram. They can engage with customers directly in groups or through Messenger and WhatsApp, and they can tell their stories in creative ways with Reels, Stories or by going live on Facebook and Instagram. With personalized ads, they can easily reach the people most likely to be interested in their products or services for just a few dollars. This has helped so many businesses, especially small businesses, find success when reaching people in person have been much harder. A great example is The Pizza Cupcake, a family-owned baking business in New York City. They've been selling at pop-up shops since 2018.
When COVID hit, pop-up locations shut down and catering events canceled. In March last year, they became an e-commerce business. In Q3, they tested their first Facebook ad campaigns in the New York tri-state area, and by the following quarter, ramped up their budget to sell across 28 states. They've since made three new hires and plan to start shipping nationwide this year. They've expanded production, which has also led to jobs being created at fulfillment centers in Maryland, Florida, Arizona, and California. We're constantly working to improve the effectiveness of our ad products to help businesses like The Pizza Cupcake reach customers and get a great return on their investment. We're doing this through investments in machine learning and monetization of newer surfaces like Stories and Reels. In all of this, we're planning for the long term.
Mark talked about some of the key elements of our strategy going forward. I'll focus on the strategy for the ads business. If you think about the journey we've been on over the past decade or so, we started with desktop ads on the right-hand side of people's feeds. Consumers shifted to mobile, and we put ads in News Feed. Quarter after quarter, year after year, as we've created great new consumer products like Stories or Reels, we found the right way for advertisers to reach consumers within these products. We're constantly working to make our ads deliver more for businesses and be more relevant for people.
To support the growth of our ads business over the next 10 years, it's going to take a similar effort. We need to build on our success by developing innovative new products and discovery experiences while giving everyone more control over their personal information. To build the next era of personalized experiences, we're focused on product innovations in four areas. The first is discovery. We want to keep making our apps the best places to discover products and businesses you'll love. For example, we're testing a new experience in News Feed where you can tap to browse content from businesses on topics like beauty, fitness, or clothing. We're using context to make smarter recommendations about which ads to show. If you're watching a travel video, we could show ads for hotels and flights.
The second area is commerce, which Mark touched on a moment ago. We're building a modern commerce system across ads, community tools, messaging, shops, and payments. It's all about creating a personalized, seamless customer journey where it's easier to discover a product, buy it, pay for it, and have it delivered to your doorstep. The third area is privacy-enhancing technologies. We know businesses are experiencing challenges because of platform changes. We wanna make sure they can continue getting great results through privacy-safe, personalized ads long into the future. We're collaborating across the industry to develop new technologies to help minimize the amount of personal information we process while still allowing us to show relevant ads and measure their effectiveness.
The fourth is building tools that help businesses beyond marketing. We wanna help solve all kinds of business needs, whether it's customer relationship management, business messaging tools, or hiring through Facebook Jobs. We're helping people run their business across our apps easily with Facebook Business Suite. We're making it easier to message customers across our apps from a single interface. We're expanding our Messenger API for Instagram as customers increasingly rely on messaging instead of phone calls. The digital transformation is a long-term trend that isn't going away. By focusing on innovation in these four areas, we will continue to help businesses of all sizes make the shift online and reach customers with privacy-safe, personalized advertising. As ever, I'm grateful to all the businesses who work with us, and I continue to be amazed by our teams all over the world.
Throughout this period, we've been really lucky to have so many brilliant people working hard to keep people connected and help businesses survive and thrive online. Now, over to Dave.
Thanks, Sheryl, and good afternoon, everyone. We delivered strong results in the second quarter as our services continued to help millions of businesses reach customers around the world. Let's begin with our community metrics. We estimate that approximately 2.8 billion people used at least one of our services on a daily basis in June, and that approximately 3.5 billion people used at least one on a monthly basis. Our global community continued to grow even as we lapped elevated user growth in the second quarter of last year related to the pandemic. Facebook daily active users reached 1.91 billion, up 7% or 123 million compared to last year. DAUs represented approximately 66% of the 2.9 billion monthly active users in June. MAUs grew by 194 million or 7% compared to last year.
Turning to the financials. All comparisons are on a year-over-year basis, unless otherwise noted. Q2 total revenue was $29.1 billion, up 56%, or 50% on a constant currency basis. We benefited from a currency tailwind, and had foreign exchange rates remained constant with Q2 of last year, total revenue would have been $982 million lower. On a two-year basis, Q2 total revenue growth decelerated to 72% from 74% in the first quarter. Q2 ad revenue was $28.6 billion, up 56%, or 51% on a constant currency basis. The macroeconomic environment for online advertising remains very strong. As Sheryl noted, the growth in the advertising revenue was largely driven by verticals that have performed well during the pandemic, such as online commerce and consumer packaged goods.
In addition, we have, we saw improved growth trends in verticals that were particularly challenged during the pandemic, such as travel, entertainment, and media. On a user geography basis, ad revenue growth accelerated in all regions as we lapped the strongest quarter of last year. This is the second quarter of last year, which was the period hardest hit by the pandemic. Growth was strongest in the Rest of World at 86%. Europe, Asia Pacific, and the U.S. and Canada grew 63%, 56%, and 48% respectively. Europe, Asia Pacific, and Rest of World all benefited from currency tailwinds. In Q2, the total number of ad impressions served across our services increased 6%, and the average price per ad increased 47%. Impression growth was primarily driven by developing markets, especially in Asia Pacific, while pricing growth benefited from broad-based strength in advertiser demand.
Recall that in the second quarter of 2020, the effects of the pandemic contributed to elevated impressions and depressed prices, which we are now lapping. Other revenue was $497 million, up 36%. Other revenue growth continues to be driven by Quest 2 sales, though the rate of growth slowed in the second quarter as we entered a seasonally slower sales period. We also recorded a revenue adjustment for returns related to the Quest 2 foam facial interface recall. Turning now to expenses.
Q2 total expenses were $16.7 billion, up 31% compared to last year. In terms of the specific line items, cost of revenue increased 41%, driven by consumer hardware costs, payments to partners, and core infrastructure investments. R&D increased 37%, driven primarily by hiring to support our core products and consumer hardware efforts. Marketing and sales increased 15%, mainly driven by hiring and marketing spend. Lastly, G&A expenses increased 23%, driven mostly by employee-related costs and legal expenses. We added over 2,700 net new hires in Q2, primarily in technical functions. We ended the quarter with over 63,400 full-time employees, up 21% compared to last year.
Second quarter operating income was $12.4 billion, representing a 43% operating margin. Our tax rate was 17%. Net income was $10.4 billion or $3.61 per share. Capital expenditures, including capital leases, were $4.7 billion, driven by investments in data centers, servers, network infrastructure, and office facilities. Free cash flow was $8.5 billion. We repurchased $7.1 billion of our Class A common stock in the second quarter. We ended the quarter with $64.1 billion in cash and marketable securities. In terms of our sustainability efforts, we remain focused on achieving our goal to reach net zero emissions for our entire value chain in 2030.
In June, we released our 2nd annual sustainability report, which details our work towards achieving our objectives. Turning now to the outlook. Similar to the second quarter, we expect that advertising revenue growth will be primarily driven by year-over-year advertising price increases during the rest of 2021. In the third and fourth quarters of 2021, we expect year-over-year total revenue growth rates to decelerate significantly on a sequential basis as we lap periods of increasingly strong growth.
When viewing growth on a two-year basis to exclude the impacts from lapping the COVID recovery, we expect year-over-two-year total revenue growth rates to decelerate modestly in the second half compared to the second quarter rate. We continue to expect increasing ad targeting headwinds in 2021 from regulatory and platform changes, notably the recent iOS updates, which we expect to have a more significant impact in the third quarter compared to the second quarter. As noted in recent earnings calls, we continue to monitor developments regarding the viability of transatlantic data transfers and their potential impact on our European operations. Turning now to expenses.
We expect 2021 total expenses to be in the range of $70 billion-$73 billion, unchanged from our prior outlook. The year-over-year growth in expenses is driven primarily by investments in technical and product talent, infrastructure, and consumer hardware-related costs. Our expense outlook reflects our commitment to invest ahead of the compelling long-term growth opportunities we see across our product portfolio. We expect 2021 capital expenditures to be in the range of $19 billion-$21 billion, unchanged from our prior estimate. Our capital expenditures are driven primarily by our investments in data centers, servers, network infrastructure, and office facilities. We expect our full year 2021 tax rate to be in the high teens. In closing, we are pleased with the strong performance of our business and remain committed to innovating on behalf of the people and businesses who use our services around the world.
With that, France, let's open up the call for questions.
Thank you. We will now open the lines for a question-and-answer session. Our first question is from the line of Brian Nowak with Morgan Stanley. Please go ahead, sir.
Thanks for taking my questions. I have two. The first one on shopping and sort of all the Instagram and Facebook shopping efforts. You've been sort of at this for over a year now. Mark, I thought your comments about it's gonna take a while before it's meaningful tonight were somewhat meaningful. Talk to us about sort of what are one or two of the key execution areas you really need to overcome to make this shopping opportunity really be larger for the company over the next few years. Secondly, on the creator economy, you know, there's a lot of different platforms with reach and algorithms sort of attacking this creator economy. Maybe just help us better understand a little bit the way you intend to really compete for creators to bring more exclusive content to your platform. Thanks.
Sure. I think I can probably take both of those. On commerce, I think the main thing to keep in mind is just the ads business is so large that it's gonna take a long time before anything that we do with commerce is gonna be particularly meaningful at scale. I think overall, the strategy is really to work our way down the funnel from, you know, from discovery and all the things that we're already world-class at with ads, to making it so that those ads increasingly Point to Shops across our different services. In order to do that, each layer of the funnel that we're working on, we wanna be world-class on its own.
Which means that basically there's this whole long tail of functionality that businesses have come to expect on the web and from other tools, and we need to make sure that that's available for s hops and business messaging and all of the tools, whether we do that through partnerships with other e-commerce companies or building it up ourselves. You know, we're seeing meaningful improvements every quarter in this in terms of how effective these are. There are already a pretty meaningful number of merchants and people who are using s hops. We expect this to compound over the coming years.
I just think in terms of the scale of the ads business that we're starting at, I just think realistically we shouldn't expect that this is going to be a meaningful driver of our business or profitability in the near term. It's just gonna take a while for that compounding to become meaningful numbers. I think the strategy is the right one. It's creating a better product experience for people. You know, when you click on an ad or when you engage with a business, it just can be much better to do that natively, whether you're in Instagram or Facebook or WhatsApp or whatever you're using, than go to a website that, you know, doesn't have your payment information and isn't personalized.
I think we're on the right path here, and we're focused on compounding this as quickly as we can. I guess for the second question on the creator economy, I mean, yeah, there are a number of different companies that are focused on this. I'd say there are a couple of things here that are interesting properties of this. One is that if you're a creator and you're trying to get your content out there and you're trying to make a living, you wanna be on all these different platforms. I think a lot of what we're trying to do is it's not necessarily the case that, you know, that people are gonna be on one platform versus another. We just wanna make it so that the creators have their best content here, and that we can help them make a living better than other platforms.
We think that if we do, we'll have an advantage on content over the long term. It's not like we fundamentally have to win creators over from another place. You know, our monetization tools, I think are a pretty big advantage that we bring to the table. Our advertising is world-class. The ability to basically help creators make more money from the work that they're already doing, I think is something that we should really be able to bring those set of tools to the table. We also have a lot of distribution that and ability to for people to find their communities and, You know, help personalize recommendations to help connect people with the people who are gonna be interested in their content. I think that that is, that's some of what we're seeing and why a lot of creators are excited about the work that we're doing.
Over the long term, I think if we're able to make it so that millions of creators are able to make a living across our platforms, I think that that's just gonna mean that there's gonna be a long-term breadth and healthy set of content across the systems that I think is gonna be increasingly important, especially as video becomes more important on our platforms, like what we're seeing both with Watch and Reels now.
France, we can go ahead and take the next question.
Our next question is from Justin Post with Bank of America. Please go ahead.
Great. Thanks for taking my question. Maybe one for Dave and one for Mark. First on the DAUs, you're kind of back where you were in Q1 last year for U.S. and Europe. How do you feel about how reopening's affecting activity and penetration levels today? Where could they go from here? Then Mark, really appreciate all the commentary on the metaverse. I think some companies would build in private. Appreciate the thoughts around that. Maybe first, what's kind of the business model on a very high level? Second, what kind of disclosures could we see on expenses around AR/VR? Looks like maybe up to 20% of job openings are Oculus. Looks like the investment's already started. I was wondering if you might be able to how you're thinking about giving us updates around that. Thank you.
Yeah. Thanks, Justin. On the DAU front, you know, we are seeing those trends being impacted by COVID. That's especially noticeable in some of the, you know, larger markets where we have high levels of penetration, like North America and Europe. I'd say in North America, given our high level of penetration, we do expect MAU and DAU levels to bounce around from quarter to quarter given kind of how significantly penetrated we are in that market. Then, you know, in Europe, we're seeing, you know, combination of seasonal slowness as well as COVID-related softness. When we saw restrictions ease, obviously, you know, with Delta, we might see other trends. It's hard to predict how that's going to play out in this cycle. That's kind of the best read on it I can give you at this point.
Sure. On the metaverse point, you know, what we're primarily focused on here, before I get into the business model, you know, our basic playbook as a company is build products that get to scale, especially social products. It's important that the people you wanna interact with are there. We're going to focus on having hundreds of millions of people use the metaverse and the new platforms that we're building before we really turn this into what I expect to be a very important and big part of the business.
Overall, I think that there's as we embark on this next chapter, ads are gonna continue being an important part of the strategy across the social media parts of what we do, it'll probably be a meaningful part of the metaverse, too. I think commerce is gonna be increasingly important, which is why we're one of the reasons why we're focused on this across our current apps and the current economy. I think digital goods and creators are just gonna be huge, right? In terms of people expressing themselves through their avatars, through digital clothing, through digital goods, the apps that they have that they bring with them from place to place. A lot of the metaverse experience is gonna be around being able to teleport from one experience to another.
Being able to, you know, basically have your digital goods and your inventory and bring them from place to place. I think that's gonna be a big investment that people make. Our focus for now is really on, you know, helping to develop the community, helping to develop the number of people who and grow the number of people who can be in these metaverse experiences and can experience some of these next computing platforms like virtual and augmented reality. That's, I think, what you should expect us to focus on for the next period. Over the long term, I think that there's gonna be a very big digital economy around this, and that's what we're primarily gonna be shooting for.
You know, our business model isn't gonna primarily be around trying to, you know, sell devices at a large premium or anything like that, because our mission is around serving as many people as possible. We wanna make everything that we do as affordable as possible so as many people as possible can get into it and then compound the size of the digital economy inside it. That's kind of at a high level how I'm thinking about this, and I'm happy to talk about this more as we continue to evolve the investment. Dave can speak about the expenses and disclosures and all that. I will note that I appreciate the ingenuity and cleverness of looking to our job descriptions to see where we're investing. This is a big focus, as I called out in my comments at the beginning.
Yeah. Justin, I mean, obviously from a capital allocation perspective, our overall focus is on growth. You know, we've repeatedly called out that as it relates to our investments in innovation, FRL is a big focus area for us and a major investment driver in our expense outlook. You know, we have mentioned that we're investing billions of dollars annually, and we expect to invest in this area for the foreseeable future as we make progress towards building this next computing platform. There's a lot of hard work that needs to be done, but it is a big focus. We haven't provided any more granularity on it. Okay, France, you can go ahead and go to the next question, please.
Our next question is from Douglas Anmuth with J.P. Morgan. Please go ahead with your question.
Thanks for the questions. I'm going to go with 2 for Dave. Just first on the mix of slower impression growth and then with price as the driver here for the year, is there anything else that we should be thinking about beyond the comps from last year? How do you think about expanding services to create more ad inventory going forward? Secondly, just curious if your view on ATT has changed over the past three months at all, and if you could comment at all just early on on some of your mitigation efforts and what you're seeing there. Thanks.
Yeah, sure, Doug. In terms of impression growth, you know, we had called out last quarter that we would expect for the remainder of 2021 for pricing to be a bigger driver of growth, and mentioned at that time there were a few factors driving it. The biggest factor is, you know, lapping the COVID engagement that we saw that was particularly pronounced in North America, where we saw more engagement related to the lockdowns and a higher impression growth last year. That is one of the big factors. The other factor that we're seeing is shift towards video, both for our products and other products. That's just generally a big trend in the market, and that tends to have lower impressions per the amount of engagement than things like News Feed.
Kind of both those things are factors, but the COVID factor is the one that I would call out. When you think about how we're expanding services to create more ad inventory, you know, I would say that we've got a number of impression growth opportunities. You know, we've seen growing impression contributions from new services like Instagram Explore, broadly within video, Marketplace. When we look forward, I think Reels is a really, you know, significant future opportunity. We've only just really begun to make ads available globally on Reels. When you kind of look at all of these different surfaces, we think there are a lot of good growth opportunities. They're still, you know, small in absolute size compared to things like Feed and Stories, but big opportunities for growth.
In terms of your question on ATT, you know, the impact from the ATT changes has really generally been in line with our expectation. You know, we're obviously benefiting, as others are from a very strong macro environment for advertising. Look, this has been very challenging for advertisers to navigate, and we're working with them to help them navigate these changes. We've introduced solutions to help them do that through approaches like our Aggregated Event Measurement API, which uses aggregated data for targeting and measurement. Obviously, we're doing a lot of work on, you know, using machine learning and AI to help rank ads and make them more valuable.
You know, overall, we do think there are opportunities to continue to improve, you know, our capabilities, you know, through investments in areas like machine learning and AI to make ads more effective. If we can, you know, get advertisers to get the same number of conversions from fewer ads, that's great. That works for them, and it creates more value for the ads for us. Okay, France, we can go to the next question.
Our next question is from Mark Mahaney with Evercore ISI. Please go ahead.
Okay. Two questions, please. Back on the metaverse investments, Dave, will you take a swing at that question about how much expense associated with building out the metaverse that investors should expect? You know, we came up with our own crude numbers of maybe $5 billion a year. Are we anywhere ballpark close on that? Given the rise in pricing, just address the issue, I know you've done it in the past, the extent to which that's had a material impact on ROI for marketers. I know it's an auction-based system. You know, as prices rise, is there any reason to be concerned about whether there will be some marketers that would be priced out because of that and create less optimal outcomes for your platform? Thanks a lot.
Yeah. Sure, Mark, I sort of hit this with Justin's earlier question. You know, we haven't given a specific breakout on what we're investing in FRL. It's obviously a significant investment. We've, you know, categorized it as billions, your number is billions. It's consistent with us saying billions. Beyond that, we don't have any more specificity to give. It is a, you know, certainly a significant investment. You know, I would say that is inclusive, obviously, of all of the efforts we're making across FRL, not just the metaverse. On pricing and ROI, you know, Sheryl, you might be able to give some color on that as well. You're muted, Sheryl. Hang on a second.
Sorry. On pricing and ROI, you know, the beauty of an auction is that people can see the prices they're paying, they're able to measure the results, then bid appropriately. As people get more specific, more personalized, more targeted in what they're doing, even if prices are rising, they can find the buys within the system that work for them. The good news is that's good pressure in the system because it makes the ads more relevant for the people who are seeing them. Once you are really, you know, incentivized within an auction to find the thing that is returning for you, that's actually almost always the thing that is the most relevant for people who are seeing the ads. I think that's been a good system and good pressure within the system going forward.
We're certainly seeing our large brand advertisers continue to spend and get better at using personalization in our ad formats, and we're seeing small advertisers be able to compete very effectively. Doesn't mean that rising prices aren't an issue sometimes, but I think overall, this is where the auction system serves us well, and most importantly, serves consumers well.
Okay. Thank you.
Great, France. We can go to the next question.
Our next question is from, Youssef Squali with Truist. Please go ahead.
Great. Thank you. two questions, please. First for Mark Zuckerberg, maybe going back to the metaverse vision. How much of the building blocks that you need to basically build this future is within your control versus maybe pieces that others need to build? I'm thinking particularly around the hardware side, 'cause just listening to you, it seems like this is more of a communal thing that many people, many parties, even maybe some walled gardens would need to kind of open up to embrace this. Just wondering how you kind of look at that. Then maybe Dave or maybe Sheryl , wanna go back to the impact of iOS 14.5 on targeting in general, but maybe DR in particular.
We heard from several marketers, throughout the quarter that they had pulled back, not just on Facebook, but really across the board on some ad formats like app install ads, because of ATT. I was wondering if you can maybe speak to DR versus brand. Thank you.
I can start off with the metaverse question. I do think that this is going to be a macro wave overall that a lot of companies are gonna be able to ride and benefit from. You know, whether that's companies like NVIDIA that are building a lot of the graphics chips that are gonna be really important for a lot of the content that I think is going to be increasingly graphically intense. That certainly, you know, building those kind of graphics chips is not a thing that we're intending to get into. We're certainly counting on companies like that in the industry to kind of continue improving and compounding overall.
On the hardware side, I would say that, you know, we have a pretty big program on building virtual and augmented reality devices. I mean, sure, a lot of people are still going to be using phones and computers for a long time. I think when it gets to what are the devices that are gonna deliver the deepest sense of presence and that are gonna be increasingly important over the next decade, we're certainly investing in that because we wanna make sure that those develop in a way that's in line with the vision of these platforms helping people to interact with each other and socialize.
That means prioritizing certain feature development or certain sensors in the devices that we wanna make sure that we can help push that in a direction that will help lead these to become a very social platform. Overall, I do think this is gonna be a big space. The point that I was making is that I think there are gonna be a lot of winners and this is gonna be not something that one company builds alone, but I think it is gonna be a whole ecosystem that needs to develop. We're certainly making a lot of the key investments that we need to make in the foundational technology to be able to deliver the parts that we want to.
Why don't I, Youssef, why don't I start off on it, then if Sheryl wants to add any color, she can jump in and add that. In terms of, you know, Facebook ads performing well in both, you know, direct response and brand this quarter, we, you know, we continue to see solid growth across both direct response and brand. I mean, direct response continues to be the bulk of our business and the primary driver of growth. You know, we did see a nice rebound, you know, consistent with others in the market of brand spend back on platform. Brand obviously took a big hit on a year ago basis. Really saw a bigger pullback in brand came back, you know, more strongly than DR. DR, you know, is still doing quite well.
We're seeing a lot of the categories that led during the pandemic continue to do well, and those are all highly, you know, DR-centric verticals like commerce. You know, continuing to see good performance there.
The only thing I'll add is that increasingly the brand DR distinction is less and less, you know, traditional. Large brand advertisers that have done brand advertising for a very long time are increasingly learning to do direct response ads and use our different formats and use our different measurement tools. Even the categories that people are used to thinking about, I think it's more the buy than the advertiser. As our largest brand advertisers, I think many of them are becoming increasingly proficient and effective in what would traditionally be considered DR advertising.
France, you can go ahead and go to the next question, please.
Our next question is from Ross Sandler with Barclays. Please go ahead.
Just one question for Mark or Dave, I guess a follow-up on the creator economy topic. YouTube pays $0.50 on every dollar to the creator, about $15 billion or so this year. I guess, Dave, what's the view on the financial model and how that might change as you guys lean in in this area? I know that influencers are getting paid, maybe not directly by Facebook today, but by other folks to post things on Facebook. I guess in the new world, are we looking at lower margins and are there things that might offset that, like higher engagement? Is the creator content going to be on just these new surfaces like Reels, or is it likely to proliferate everywhere, including like the news feeds on Facebook and Instagram? Thanks a lot.
Ross, I can take that. You know, I think it's a question of definition as well. I mean, we already, like YouTube, pay a lot out to, you know, the creative industry more broadly as opposed to, you know, specific individual creators. You know, for instance, we pay to, you know, on the music licensing front, you know, we do a fair amount of that. There's, you know, significant payments we make there above and beyond what we're talking about with the billion-dollar commitment to creators that Mark outlined. You know, this is obviously something that is, you know, part of the cost structure, but it's something that we've, you know, long had in our outlook.
I don't think it's a, you know, meaningful change in the business model or outlook, but it is something that, you know, we're committed to helping people continue to build, you know, vibrant, you know, communities and businesses on our platform, just like we have with advertising. Oh, France, you can go ahead.
Pardon
Go to the next question, please. Thank you.
Our next question is from Mark Shmulik with AllianceBernstein. Please go ahead.
Yes, thanks for taking my questions. A couple for Sheryl or Dave. The first on Reels ads. You know, a lot of talk around kind of the upgrade cycle to video and, you know, any color you can share around the engagement, traction, or effectiveness of kind of video ads on that type of a platform. Secondly, you know, with 1.2 million stores now on Shops, specifically those selling on Facebook, you know, are there any learnings or noticeable differences in the effectiveness of their advertising or conversion rates? Thank you.
I can start by talking about Reels ads. You know, our process has been, as I talked about, we roll out consumer products, and then we find the right ad format so that businesses can take those opportunities as well. I think, you know, that's what we're seeing. We now have Reels ads available to advertisers in almost all markets where Reels is live. It's a pretty similar format to Stories. It's full screen and in between Reels videos, up to 30 seconds. We think it's a pretty natural fit in Reels. It's a really great discovery surface, and we're seeing engagement and effectiveness parallel some of our other products, and we're really pleased with that. It's still early, but we think this has a lot of potential. Do you want me to take the second question?
Either way, Sheryl. I can take it if you want.
Yeah, go ahead. Yes.
Mark, on the second question, you know, we're obviously very focused on, you know, making sure that our ads are effective and we've got good conversion rates for our advertising partners. Part of what we're doing there, and Mark talked about this in the Q1 call, is, you know, making sure that the ad unit's optimized for whichever experience is converting the best. If you've got a store, you know, a shop on Facebook or Instagram, is that converting better or is your own web store converting better? Then that allows us to also just get better at making our Shops more effective. You know, we wanna do what's best for the advertiser and also, you know, continue to make our, you know, online and our own Shops more effective. You know, no specific numbers to share there, but we're continuing to work to make our Shops convert better.
France, we can go ahead and go to the next question, please.
Our next question is from Brent Thill with Jefferies. Please go ahead.
Thanks. Dave, just the modest deceleration to your stack. There are a lot of investor questions. You know, do you mean more two or three points or decel or is it more five to seven? Any more granularity you can add to what that modest decel looks like would be extremely helpful. Thank you.
Oh, thanks, Brent. We didn't provide specific guidance on it. You know, we obviously saw a deceleration from Q1 to Q2, from 74% - 72%. You know, we expect modest deceleration, you know, in the second half of the year, but we haven't put a specific number on that. France, you can go ahead and go to the next question.
Our next question is from John Blackledge with Cowen. Please go ahead.
Great. Thanks. Two questions. On the iOS changes, any color on the opt-in rates for Facebook and Instagram? Are they kind of in line, better or worse than your expectations at this point? On OpEx, at the midpoint of the guide, implies 39% growth in second half versus 28% in first half. Just any color on key drivers of the accelerating OpEx growth in the back half of the year. Thank you.
Yeah. Thanks, John. On the, you know, on the iOS changes, really very much in line with expectations on things like opt-in rates. I would say overall the impact has been, you know, in line with our expectations. Not a huge surprise there. You know, we're not fully rolled out with those changes, but Q3 will have, you know, the impact more or less of those being fully rolled out. In terms of the OpEx guide, yeah, we do expect accelerating expense growth in the back half of 2021. You know, we're gonna see that in areas like consumer marketing. Some of the non-headcount-related spend we expect to accelerate in the back half of the year. That's the expectation on that front. France, we can go to the next question, please.
Our next question is from Colin Sebastian with Baird. Please go ahead.
Great. Thanks. Good afternoon, everyone. Maybe a couple of higher level questions, really coming out of F8 Refresh. First off, can you talk about the integration of messaging across the family of apps and how the opening of messaging APIs is adding functionality to apps, and if this is contributing incrementally to more business activity through messaging? Then, with advanced AI and machine learning now seemingly table stakes for most platform companies, Mark, I'm just kind of curious if this is still a significant competitive advantage for you in your view. Based on what you heard at F8, I wonder how important a product like PyTorch is in terms of moving faster in new product development, things like that. Thank you.
Sure. I can take both of those. In terms of messaging, you know, we're working on cross-app communication between them, business messaging APIs, and a lot of this is very much, you know, the business messaging I think is gonna be an important part of commerce and helping people interact with businesses in a way that is natural to them. The cross-app communication in terms of helping people reach people wherever they are, it kind of fits into this vision that we have for the future of people being able to easily teleport between experiences that I think is gonna be increasingly important as we move towards the metaverse. People are gonna need messaging services. That's gonna continue to be a core way that people communicate.
People are gonna wanna reach the people they care about no matter what service they're on and be able to move between these. When I talk about kind of interoperability, in moving more there in the future, we're trying to get our core experiences today aligned with that as well. The other thing I'd say on messaging is, you know, that connects to the business today is that, click-to-messaging ads, are one of the parts of the ad business that is growing, quickly and doing quite well.
Part of that is because, you know, even if we're not charging a lot directly for the messaging APIs for businesses that if the interactions between people and businesses end up helping businesses convert better and drive more sales, then business is naturally going to wanna, you know, pay to have their ads point towards that rather than other surfaces that we may not control or that may be a worse experience. That's on the messaging side. On the AI side, I think this is a really good question. It's probably something that doesn't come up as much on these earnings calls as it probably should for how important of a driver the progress in AI is for our overall result.
You know, one of the things that I've observed in just running the business over the last couple of years is, you know, there's a lot of focus on, on kind of different headwinds that we may face, whether it's from other platforms or regulation or different things. One of the areas that I think has routinely outperformed our expectations is progress on AI. You know, we don't have a single product which is, like, an AI product, that's sort of the embodiment of all the AI work. That's not something that we've done yet. We basically, we have a very large investment in AI, and we build out this platform that then all of our products use.
When we make foundational improvements, it makes ranking better in News Feed and in Reels and in Ads, and it makes our spam detection and our integrity systems more effective at identifying stuff. Everything just gets better, and this has really been one of the big tailwinds or waves that we've been riding. Just from what I can see technologically on the horizon, it really doesn't seem like this is going to be slowing down anytime soon. I don't think that this is a Facebook-specific thing. I think that this is probably across the whole industry or maybe even across the whole economy more broadly. I do think that the progress that's being made at the fundamental levels with AI is driving a lot of progress and is one of the important macro effects that we're seeing.
For PyTorch specifically, you know, I mean, it certainly helps that the framework that we use to develop our AI work, is one that's embraced by the community. You know, a lot of times when we go to spin up a new project, you know, there will already have been some team that contributed an open source library to it. That makes it easy. I think that there certainly are dividends that we get from having developed or helped develop PyTorch to become, you know, an increasing standard, especially among researchers. It's certainly an area that we're gonna focus on investing more in. I think that the core AI platform is just an important part of the progress that we're seeing overall.
France, I think we have time for one last question.
Very good. Our last question will be from the line of Michael Nathanson with MoffettNathanson. Please go ahead.
Great. Thanks. One for Sheryl and one for Dave. You know, Sheryl, in the past I've asked you this question, but now we're seeing it. Post-pandemic, there's been a real weakness in TV impressions, and those TV dollars are going, it looks like, to AVOD and YouTube. Can you talk a bit about your vision for video and how that may sync with the opportunity and maybe grab some of those TV dollars? Would you expand the definition of creators to include premium video content or sports? For you, Dave, following up on Doug's question, can you talk a bit, I know it's early, about the learnings from your Aggregated Event Measurement? What has been the impact on things like signal loss, ROI, or spending from those who've used it in the early days? Thanks.
I can talk about video ads. We're seeing very strong growth in video monetization across Watch, Feed, Reels, and we think we're continually getting better at monetizing video. They are still monetizing at lower rates versus Feed Stories. We have, you know, we have a lot here. We have 2 billion people watching in-stream ad-eligible videos per month. Mobile-first video is increasing, meaning even brand advertisers are getting better at doing mobile-first video. Certainly, we think advertisers are looking for the best place to reach audiences, and we compare very favorably across the board. I'll share a really, I think, cool recent example. Walmart, you know, a very large advertiser, engaged Ree Drummond, who's The Pioneer Woman cooking show host, to host their first live shopping event. The event was to launch her Walmart-exclusive line of home and fashion products.
They used a mix of our personal ads to drive awareness to a live shopping event and then re-engage viewers after the purchase. They had really great results across the board. They ran part of that live as video ads and resulted in thousands of engagements, a lot of engagement with people and sales. I think that's a good example of our products like Live, combined with the use of video on our platform, combined with people taking an opportunity for video ads and putting it all together in ways I think will compete very favorably with older formats like TV.
Mike, I'll take the second question. I don't have specific data to share, but I mean, just contextually, the work that we're doing with the Aggregated Event Measurement API is part of the broader work that we're doing to rebuild meaningful elements of our ad tech so that our system can continue to perform while having access to less data in the future. It really dovetails into some of the work that Mark was talking about with machine learning and AI, because that's gonna be an important part of being able to make better use of less data. Again, why having access to the ML and AI capabilities that we have with Facebook is gonna be so important to the future in maintaining and growing the efficacy of ads.
You know, I think, you know, broadly, we're pleased with the progress we're making on this. You know, it is disruptive for advertisers to have to, you know, go through the process of, also, learning how to retool. You know, I don't wanna lessen the impact this is having on our advertisers. I think it is a challenging period for them, and we're trying to help them work through it as effectively as we can. With that, I think we are done. Thank you, everybody, for joining us on the call today, and hope everybody stays safe.
This concludes today's conference call. Thank you for joining us. You may now disconnect your lines.
