Thank you, Matt. Hello, everyone. We had a strong start to the year, continuing our momentum from Q4 into Q1. Nextdoor is benefiting from the combined tailwind of the rise of local and social commerce. Neighbors remained highly engaged in their communities, resulting in a third consecutive quarter of accelerating year-over-year weekly active user, or WAU, growth. This contributed to sustained revenue growth of 48% year-over-year, consistent with Q4, and Q1 ARPU growth of 12% year-over-year, driven by continued advertiser demand. We are mindful of the macro backdrop, war in Europe, lockdowns in China, U.S. Consumer Price Index at 8.5%, and consumer sentiment at its lowest level since 2011.
We also know that in times of need, Nextdoor is a platform that neighbors turn to for help, and we are a unique and differentiated platform for advertisers of all sizes. Our purpose is our North Star, cultivating a kinder world where everyone has a neighborhood to rely on. Neighbors come for trusted information, to give and get help, and to create relationships online that can be expanded into the real world. Nextdoor is about place, facilitating online action that results in real-world outcomes. For example, joining a local running group and meeting in your neighborhood for a run, offering a kid's bike at a discounted price and then selling it to parents on your block, or engaging your community to petition for a new bus route and coming together at City Hall to make the case.
We are about all neighborhood stakeholders, businesses, public agencies, local schools, churches, and nonprofits, to name just a few. The social commerce revolution is happening, and Nextdoor is uniquely positioned to drive and grow with this fast-paced change in consumer behavior. Social commerce is weaving buying and selling into the fabric of everyday life and through a real sense of community and connection. People want to buy products and services based on recommendations and inspiration from people they trust. We know that neighbors are one of the most truly trusted groups and some of the biggest influencers in our lives. From our latest insight survey, 71% of neighbors have shared a business recommendation on Nextdoor, 96% of neighbors have seen one, and 72% have been influenced by one. This feeds directly into our product strategy, and improving our Nextdoor ad platform plays a foundational role.
What differentiates Nextdoor is our hyperlocal trusted approach to building an active, valued community. As the world experienced significant political and economic disruption in Q1, neighbors turned to the platform to support each other. Neighbors organized food drives and created groups to mitigate the impact of rising inflation. They organized fundraisers, donations, and awareness initiatives to support Ukrainian neighbors locally and globally. Nextdoor itself partnered with the UN Refugee Agency on a native media ad campaign, where Nextdoor raised donations and delivered higher click-through rates than the UN Refugee Agency's other digital channels, underscoring the giving power of neighbors. Our community is active and becoming increasingly active. Our product strategy in 2022 is centered on strengthening engagement through building an active, valued community. It's working.
In Q1, over 50% of neighbors were weekly active, and over half of weekly active users were active daily, highlighting that as we move neighbors from onboarding to monthly to weekly, they have a high propensity to make Nextdoor a daily use case. Everyone is a neighbor. Our continued strength in international growth underscores that this is a global opportunity, solidifying our confidence in the opportunity ahead. In Q1, international WAU grew 55% year-over-year, accelerating quarter-over-quarter from 47% in Q4 and year-over-year from 39% in Q1 of 2021. In international, engagement metrics surpassed even the U.S., with 55% of neighbors active weekly. In 2022, we will remain focused on driving growth and engagement in our existing international markets.
One of our key product initiatives in 2022 is Connections. Q1 was our first full quarter with Connections launched between neighbors, and we're pleased with the early momentum. Connections provides an important signal of who you know, allowing us to better personalize the newsfeed and notifications and hence drive deeper engagement. It's also a long-term growth driver. Neighbors invite neighbors they know who are not yet benefiting from the utility and community Nextdoor provides. Looking ahead, we plan to expand Connections to all neighborhood stakeholders, starting with small and mid-sized businesses, SMBs. Neighbors want to hear from and recommend organizations they know and trust, and they value SMBs as important members of their community. In fact, neighbors have recommended over 5 million businesses and shared over 55 million business recommendations on Nextdoor. This drives business growth.
As one customer put it recently, "Your recommendations are dynamite." Moving to our monetization efforts. In Q1, we reached an important milestone with our proprietary campaign management platform, Nextdoor Ads, making it available to all U.S. SMB customers. Nextdoor Ads is designed to provide advertisers of all sizes, including SMBs, with a simple, hyperlocal, self-service advertising experience. U.S. SMBs now have an easy solution they can leverage to meet their business goals, such as increasing traffic to their website or their Nextdoor business page, promoting a sale or a discount, or communicating directly with warm local leads. The enhanced dashboard enables performance tracking, and over time, we plan to offer advice on what's working and not working across business verticals and across communities, all with a differentiated hyperlocal lens. The second pillar of our ad platform investment in 2022 is Nextdoor Ad Manager, which is our proprietary ad-serving platform.
It will take the place of our existing third-party solutions and will enable us to better utilize our first-party data. We believe neighbors will benefit from more engaging, useful, and actionable ads, and advertisers will benefit from a higher return on investment from their ad dollars. Since the last time we spoke, we've made significant strides in solidifying the foundation of Nextdoor Ad Manager, which will enable us to scale with demand as we migrate advertisers throughout the year. In addition to strengthening our ad tech stack, we're also improving our measurement and targeting capabilities through our first and third-party tools, delivering ever-increasing value to advertisers. We see this in our revenue outcomes.
In Q1, The Farmer's Dog, a leading pet food delivery service, nearly doubled their spend quarter-over-quarter, given strong campaign performance, particularly on their conversion and cost per acquisition goals, and have increased spend further in Q2. We've made significant strides in Q1 that will set us up for continued success in the rest of 2022. Our top priorities for the year remain growing engagement while adding new neighbors to the Nextdoor platform and building products that deliver differentiated results for advertisers of all sizes. With that, I'll turn it over to Mike for our financial highlights.
Thank you, Sarah, and good afternoon, everyone. I'm pleased to report that we started 2022 on a strong note. In Q1, we saw a third straight quarter of accelerating neighbor growth, with WAU reaching 37 million, up 33% year-over-year. Total revenue was $51 million, which is an increase of 48% year-over-year. Even through an uncertain macro and geopolitical environment, we saw healthy demand from our advertisers, particularly on our U.S. newsfeed, where neighbors spend the most time on Nextdoor. Resilience in core verticals like home services offsets some softness in verticals like financial services. We are still early in reaching new verticals and continue to see demand from advertisers at all levels of the funnel, with a slight trend towards direct response, although we are still quite balanced between performance and brand awareness advertising.
Q1 global ARPU grew 12% year-over-year to $1.39, driven by higher session frequency as a result of deeper engagement amongst our neighbors. We also saw strength in ad pricing in the quarter. We continue to innovate to create new and useful ad formats, including keyword search ads, which we launched in the first quarter of 2022. Advertisers running sponsored search today are getting 3-4 times better cost per click compared to a regular display ad on the newsfeed, which is another strong indicator of Nextdoor's high-intent audience. Adjusted EBITDA for Q1 was a loss of $20 million, representing a 10-point year-over-year improvement in adjusted EBITDA margin. While Q1 is our seasonally lowest adjusted EBITDA quarter, cash flow from operations was -$6 million as we benefited from positive working capital trends. I'll end with our outlook.
The high end of our full-year revenue guidance remains unchanged at $256 million. Given the macro environment, we are providing a wider range of $252 million-$256 million, which is a year-over-year growth rate of 32% at the midpoint of the range. We expect full-year 2022 adjusted EBITDA margin to be -18%, a five-point year-over-year improvement consistent with our prior guidance. For Q2 2022, we are expecting revenue between $54 million-$56 million, a year-over-year growth rate of 20% at the midpoint of the range, and an adjusted EBITDA loss of between $21 million-$19 million. We are excited by the scale of our opportunity and our ability to execute against it. Thank you for joining our earnings call today.
With that, I'll turn it over to the operator for Q&A.
Thank you. If you would like to ask a question, please press star followed by one on your telephone keypad. If for any reason you would like to remove that question, please press star followed by two. Again, to ask a question, press star one. As a reminder, if you are using a speakerphone, please remember to pick up your handset before asking your question. We will pause here briefly as questions are registered. The first question is from Mark Mahaney with Evercore. Your line is open.
Okay, thanks. I think I just wanna ask questions on the ad products, Nextdoor Ads and the keyword search ads. Could you describe how the pace at which those are rolled out, when will those be, you know, fully available to all marketers on the platform? I think these are just rolled out in the U.S., is that right? Then the kind of the reaction. I know you've already talked about a little bit, but maybe a little bit more detail on the kind of adoption you're seeing and, you know, with those ad units, what it's doing to. Is it material enough to actually cause a spend per advertiser to increase? Thank you very much.
Great. Thank you, Mark. I'll start. I appreciate the question on the ad platform. I'll start talking about Nextdoor Ads, which I talked about a little in my prepared remarks as well. That is the front end to our ad platform. It's a proprietary campaign management platform. The big milestone that we've been working to for the last several quarters, even longer, perhaps, is to get that out to all U.S. SMB customers. You're right, it's just launched in the U.S., and now we're turning our attention to the rest of the world. The larger portion, clearly, of our SMBs today are here in the U.S. What is that giving them? Easy to use, really intuitive self-serve platform. It allows SMBs to now access Nextdoor's ad formats beyond local deals and neighborhood sponsorships.
Now they're getting access to more visual options, additional placements in the app itself, and new CTAs, new calls to action. With that, we think it will continue to drive interest from small businesses on the platform. As you know, today, about 30% of our revenue is coming from SMBs, but we do think that over time, this can be even bigger. In addition to what you see on the front end and what, our neighbors get to see from those SMBs, we also now have a much more comprehensive dashboard for them with better and more detailed metrics for performance tracking.
Again, this is a place where we think we can really differentiate ourselves from other platforms, because, for example, we can tell you what are the search terms that are happening in a neighborhood right now in and around your business. I was talking to an advertiser, who's actually on the front of our shareholder letter, in the junk removal business. Not only did he wanna know on his dashboard, what were the metrics for the ads he was putting out there, but he was also interested in knowing what was search that was happening in that neighborhood. Are neighbors actually looking for the types of offerings that he has? We think we can do something really different there.
In addition, if we think about, that's the front end Nextdoor Ads, the back end is Nextdoor Ad Manager, and that's going to be a full-year move for us to get back onto our proprietary back end, away from some of the third parties that we've worked with over the last several years. What that's gonna allow us to do is to make much better use of that proprietary first-party data, apply data science and ML to it to make sure that the right ad is going to the right person at the right time. When we can do that, we know we're gonna have much better performance for advertisers, but also a much better outcome for neighbors. Nextdoor's utility will really sing. You mentioned search.
We know that neighbors are coming to Nextdoor all the time, to look for recommendations and making it easier for them to find that through much more enhanced search has been a key milestone for us as well. Today, we're now running sponsored search for advertisers, although it's still in the early days. It's gonna take us multiple quarters, I think, to really get that to scale.
That was the data point Mike mentioned, which when someone does sponsored search, we get a 3-4 times better cost per click compared to a regular display ad on the news feed. I think that's indicative of just the high-intent audience that Nextdoor has. Lots going on overall in the ad platform, but I really can't underscore what a big milestone getting Nextdoor Ads launched is for us. Now we can really get back to focusing on the back end and how we serve.
Thank you, Sarah.
Thanks, Mark.
Thank you, Mr. Mahaney. The next question is with Eric Sheridan, Goldman Sachs. Your line is open.
Thanks so much for taking the question and hope everyone on the team as well. I'd like to go back bigger picture, maybe to the user side of the equation. Can you give us a more detailed update on what you're seeing both in terms of international user growth and international engagement? How much of that you're seeing from an organic nature versus maybe some of the investments you'd like to make in growing scale on the international user side? The second part of the question would be, you've talked before about personalization getting that increasingly right as we move from 2022 into future years. Can you talk a little bit about personalization and how you expect that to be a driver of more repeat activity and engagement on the platform overall? Thank you.
Great. Thank you, Eric. Yes, we're doing fine, although we recognize that this is a bumpy market that we're all living through at the moment. First of all, on engagement overall, you saw the 33% year-over-year growth in WAU, the third consecutive quarter of accelerating WAU growth. We're very pleased that clearly the changes that we're making from a product standpoint, and just as we grow, we create more content, which creates more utility and more community for neighbors. Going to international, specifically, we saw a 55% year-over-year growth in international WAU, and that accelerated year-over-year and quarter-over-quarter as well, so very nice acceleration. The other thing I would note is that international neighbors, from a weekly active perspective, are actually higher than what we see in the U.S.
In the U.S., about 50% of our verified neighbors are weekly active, and in international, it's 55%. You actually see that uptick. I think some of it may actually just be cultural, for example. In terms of what we're doing to continue to drive that engagement, it's really three things I would highlight. The first is notifications. We've talked about investing in our notification platform. Whenever a post is trending, whenever there's something that we know that you would wanna see from a personalization standpoint, we need to get that in front of you. We've been doing a lot of investment on getting the data science and machine learning right in that space, and it's paying dividends. Second thing is Connections. Connections is much younger in its journey.
As you know, we rolled it out really at the end of Q4. Q1 was our first quarter of seeing Connections in action, and thus far, we're really pleased with the numbers that we're seeing. Our thesis was that neighbors would want to connect to people that they knew in the neighborhood. When they connect to people that they know, they're getting a form of personalized content that will engage them more. Of course, then that drives the flywheel of notifications. From here with Connections, we see a couple of other ways to grow the platform. The first is to allow you to connect with other stakeholders. We know that neighbors wanna connect to small businesses or local businesses, for example.
That was particularly true during the pandemic, where they wanted to support local, and we see that continuing as we get to the other side, and start to see reopening happening broadly. The other growth factor for Connections is, as I noted, when you sync contacts, our ability to then say, "Hey, looks like there are this number of people in your neighborhood that you know, but they're not currently on Nextdoor. Would you like to invite them?" Kind of a people you may know sort of action. We know that when people invite people they know, they're more inclined to accept the invitation and to come on the platform. Connections has these wonderful flywheels of both driving engagement and driving growth.
The third area I would point to is back to ads, and I won't go through the whole conversation again of what we're doing from a product standpoint. We know that when ads are great content, and this is very particular to Nextdoor because we are a high utility platform. Seeing an ad for the plumber or seeing an ad for the class at The Home Depot, about gardening, at the moment in time when you're actually thinking about it or maybe going to ask neighbors for recommendations, those are really high engagement, high-quality content. Improving the ad platform will improve the content overall. That's, you know, I gave you the what's happening overall, what's happening in international, and then, of course, why it's happening. We think there's a lot of runway ahead.
Personalization was the second part of your question. Just a lot to do there. We, you know, frankly, we are just getting going from a machine learning standpoint on what we can do to really personalize that news feed. We also wanna make sure that we leave enough room for some of the serendipity too. You'll see us do more and more on how the app itself is unfolding to create discoverability of groups that you might be interested in, businesses that you might like and want to follow, events that are happening around you. Of course, that's just yet another way to help personalize it based on either interests that you've told us or the propensity with which you're doing things on the app.
Thank you.
Thank you.
Thank you, Mr. Sheridan. The next question is from Brian Nowak with Morgan Stanley. Your line is open.
Hi, this is Chloe on for Brian. We just have a couple of questions. The first would be on you. You've done a lot on product innovation. How are you seeing that driving user engagement in the ads that you are generating? How are you seeing that engagement trending? And then the second question would just be on OpEx. You pointed to some higher growth there in headcount personnel. What other details are you able to provide there? And any color would be really appreciated. Thank you.
Great. Thanks, Chloe. Why don't I start on the user engagement? I think you're also asking about ad engagement, so kind of that performance. I'll let Mike take the second question on personnel growth and so on and how that flows through OpEx. On user engagement, just a reminder, third quarter of accelerating WAU growth. We're really pleased with that. We think that continues to reflect both improvements on the product overall, so notifications, Connections, evolution of the newsfeed, and then better ads, but also retention as well. We've not really talked about that on the call yet, but we continue to see really strong retention rates as well. Back at Investor Day last year, we gave you retention rates. After three months, we see 75% retention of MAUs.
After six months, 65% retention, and after two years, still more than half of new neighbors are actively engaged. We know that that is kind of world-class. Those trends have stayed consistent. In fact, over the past three quarters, we're seeing increasing retention, especially for people who've been on the platform for more than a year. That's always a great sign that users who have come, who have found value, keep coming back for more. Then I think the other point I would make there is actually our strongest retention trends are among our daily active users. This is also why it's important to keep moving people down that funnel from being a verified neighbor to a monthly active, to a weekly active, to a daily active.
Because when we get you to daily, your ability to keep coming back, your retentiveness is much higher. On the ad side, what we are seeing is as we shift more and more of our own proprietary data into the platform, frankly, as we make the ability to self-serve, so to be much more innovative with your creatives and so on, make those ads more engaging, we're starting to see better and better performance. We talked about The Farmer's Dog during my prepared remarks, but that's a great example of a home delivery pet food company that came to Nextdoor to test, then they went full on, and they've actually been greatly increasing their spend in Q2 over Q1. Really, that's a result of much higher click-through rates and really to the metrics that they measure.
Nextdoor is a platform that can both act top of funnel for advertisers, so in brand and awareness driving, but also bottom of funnel direct response. It's about a 50/50 split, maybe erring a little bit more into direct response right now. I think it's important that we can do both. I'll pause there and maybe Mike, do you wanna take the question around headcount, personnel growth and so on?
Sure. Thanks, Sarah. Chloe, I think your question on OpEx growth and I think indirectly on margins, I mean, let me take that one. I mean, we're coming off of a year where we showed 18 points of margin improvement, and we're guiding to another five-point improvements this year. We recognize the shifting market dynamics, but we believe strongly in our investment plan. You know, you have to, I think appreciate that we're earlier in our product roadmap than our peers, and our future growth is really driven by our innovating today.
We know the long-term margins in our business are well established, and we've shown that we can get there, and we can demonstrate margin improvement, and that remains our plan over the next many years. In the near term, we're really focused on building the team and bringing great talent on early in the year, which allows us to do more this year and sets us up well for growth in 2023. The same is true with our marketing investments. There's benefit from having engaged users on the platform early, and so that's why we've continued to invest behind our product roadmap here in the first half in 2022.
Great. Thank you.
Thank you.
Thank you. The last question is from Ron Josey with Citi. Your line is open.
Hi, this is Jeff on for Ron. Thanks for taking my questions. First, I was just wondering on the first-party measurement solution. Are you seeing advertisers being eager to adopt this trend? Are you nearing broad adoption or when do you think you could get to more broad adoption on the first-party measurement side? From a macro perspective, is there anything, any color you can give just where you might be seeing what verticals you might be seeing weakness on the ad front, or if there's been any change in the quarter on what verticals might be weaker or stronger? Thanks.
Okay. Maybe I'll take the first question on measurement and then we'll go back to Mike on overall what we're seeing broadly in the environment. First on measurement, I would say it's actually important to have both first party and third party measurement. You know, advertisers need to be able to see that the campaign objectives they've put in front of you are working, but they also, I think, wanna make sure you're not only grading your own homework. It's definitely you need to see both. Measurement is a really top priority for advertisers, particularly 'cause there's a lot of noise out there in the environment overall because of things like IDFA, Apple's fingerprinting, right, that's coming later in the year.
For those both of those reasons, it's incredibly important right now that the Nextdoor shows off the fact that we are a proprietary ad platform, our users are logged in, and we actually have a lot of our own first party data to be able to help advertisers target and so on. Overall, if you're looking at you know from a measurement perspective, we have started to work on things such as dropping our own pixel into a particular ad so that advertisers can track not just did a click-through happen on Nextdoor, but then track that attribution more broadly. We're seeing a lot of advertisers in the direct response category add that pixel onto the ad to check the performance. I would say we're already quite well developed in terms of that happening.
Of course, you know, this points to why we're continuing to invest in our own ad serving platform on the back end because our ability to add better and better data science and then ultimately machine learning on top of that to drive performance is only gonna get better and better as we go through the year. Today, you know, over 50% of our what we call cost customer acquisition advertisers use our pixel, and that was about a 24% quarter-over-quarter increase in campaign adoption. Doing quite well on that front. With that, let me turn it back to Mike to talk about the broader macro perspective as well.
Sure. Thanks, Sarah. As we've commented in prior quarters on the impact of the pandemic and supply chain disruption, privacy, other factors, as you see now in inflation, interest rates, and geopolitical risk are the latest part of the conversations that we have with advertisers and better understanding their you know their objectives. I think it's important to understand or just to reiterate the backdrop that we're in a very attractive industry. Digital advertising grew by 35% year-over-year last year, and consensus is for double-digit growth again this year, really driven by the growth in consumer time and attention spent in digital media channels.
Specifically to our business, we've worked hard over the last few years to diversify our own revenue mix and really reducing the concentration among verticals and advertisers and different campaign objectives. That's resulted in a more resilient revenue base for us today. It's helped us, you know, to better understand the objectives of our advertisers and really be there when they need our support. We are seeing a really strong performance in home services and real estate. New verticals for us like travel and entertainment are recovering broadly.
Then for us, their new efforts for us to pick up advertisers and see what the performance that we can deliver on the platform. We have seen some headwinds in things like financial services, but what is exciting for us is we've still been able to meet the needs of our advertisers by performing for them in a different stage, different layer in the marketing funnel. Thinking about shifting ad spend away from awareness and more lower in the funnel to performance or conversion objectives, and still being able to help advertisers with large budgets to spend on Nextdoor.
Great. Well, thank you. Operator, I don't think there are any other questions, are there?
There are no additional questions waiting at this time.
Wonderful.
Again, if you would like.
Well, thank you all. Okay. Go ahead, if you wanna try again.
Again, if you would like to ask a question, press star one. There are no additional questions waiting at this time. I will now pass the conference back over for any concluding remarks.
Okay. Thank you, Tania. Thanks everyone for your questions today. We really appreciate it. We appreciate that all of you have a lot going on in this environment too. I hope that you hear how excited we are about our business, but also we wanna make sure we're staying realistic. With that, thank you, and happy to take any follow-up questions after the call. Take care. Take care.
That concludes the Nextdoor first quarter 2022 financial results. Thank you for your participation. You may now disconnect your line.
