Prepared Remarks:

Operator

Thank you for standing by. Good day everyone and welcome to the Amazon.com Q1 2022 financial results teleconference. [Operator instructions] Today's call is being recorded. For opening remarks, I will be turning the call over to the director of investor relations, Dave Fildes.

Please go ahead.

Dave Fildes -- Director of Investor Relations

Hello, and welcome to our Q1 2022 financial results conference call. Joining us today to answer your questions is Brian Olsavsky, our CFO. As you listen to today's conference call, we encourage you to have our press release in front of you, which includes our financial results, as well as metrics and commentary on the quarter. Please note, unless otherwise stated, all comparisons in this call will be against our results for the comparable period of 2021.

Our comments and responses to your questions reflect management's views as of today, April 28, 2022, only and will include forward-looking statements. Actual results may differ materially. Additional information about factors that could potentially impact our financial results is included in today's press release and our filings with the SEC, including our most recent annual report on Form 10-K and subsequent filings. During this call, we may discuss certain non-GAAP financial measures, in our press release, slides accompanying this webcast and our filings with the SEC, each of which is posted on our IR website.

You will find additional disclosures regarding these non-GAAP measures, including reconciliations of these measures with comparable GAAP measures. Our guidance incorporates the order trends that we've seen to date and what we believe today to be appropriate assumptions. Our results are inherently unpredictable and may be materially affected by many factors, including uncertainty regarding the impacts of the COVID-19 pandemic, fluctuations in foreign exchange rates, changes in global economic conditions and customer demand and spending, inflation, labor market and global supply chain constraints, world events, the rate of growth of the Internet, online commerce and cloud services and the various factors detailed in our filings with the SEC. This guidance also reflects our estimates to date regarding the impacts of the COVID-19 pandemic on our operations, including those discussed in our filings with the SEC.

Our guidance also assumes, among other things, that we don't conclude any additional business acquisitions, restructurings or legal settlements. It's not possible to accurately predict demand for our goods and services, and therefore, our actual results could differ materially from our guidance. And now I'll turn the call over to Brian.

Brian Olsavsky -- Chief Financial Officer

Thank you for joining today's call. I'd like to start with a few comments on what we're seeing as we're coming out of the pandemic, both on the customer experience side and on the operating cost side in this current inflationary environment. Let's start with demand and customer experience. Worldwide net sales in Q1 were $116.4 billion, an increase of 9% year over year, excluding the impact of foreign exchange.

This is the top end of our guidance range of $112 billion to $117 billion. Our compound annual growth since before the pandemic stands at 25%, a growth rate higher than what we were seeing before the pandemic. Our Prime members continue to be a key driver of growth. Prime members have meaningfully increased their spend since the start of the pandemic, and we continue to see consistently high member renewal rates.

We also added millions more new Prime members during the quarter. Throughout the past two years, we've seen stronger usage of Prime benefits by Prime members and a greater reliance on Amazon for their shopping and entertainment. In the first quarter, we made encouraging progress on key customer metrics. Delivery speed performance is now approaching levels not seen since the month immediately preceding the pandemic in early 2020.

And we now have the widest selection ever available for Prime's fast delivery. We have worked to protect and enhance the customer experience despite a sharp increase in costs, particularly over the past three quarters. We've seen a large cost to keep up with demand these past two years. During this period, we doubled the size of our operations and nearly doubled our workforce to 1.6 million employees.

Labor and physical space are no longer the bottlenecks they were throughout much of 2020 and 2021. However, we continue to face a variety of cost pressures in our consumer business. We'll break these into two buckets: externally driven costs, primarily inflation, and internally controllable costs, primarily productivity and fixed cost deleverage. The externally driven costs are a result of intensifying inflationary pressures throughout Q1.

Line haul air and ocean shipping rates continue to be at or above the rates in the second half of last year, which were already much higher than pre-COVID levels. Some of this is due to the impact of the Omicron variant in China and labor shortages at point of origin, and the start of the war in the Ukraine has contributed to high fuel prices. For example, the cost to ship in overseas containers more than doubled compared to pre-pandemic rates. And the cost of fuel is approximately one and a half times higher than it was even a year ago.

Combined with the year-over-year increases in wage inflation, these inflationary pressures have added approximately $2 billion of incremental costs when compared to last year. While we will continue to look for ways to mitigate these costs, we expect they will be around for some time. The next bucket of costs related to productivity and fixed cost leverage, which we consider to be more within our control and are working to reduce. These additional costs correspond to the state of the labor force and fulfillment network following two years of disruption and large demand variability.

We now look forward to more predictability in our consumer order patterns and greater stability in our operations. Let's start with labor. As a reminder, in the second half of 2021, we were operating in a labor-constrained environment. With the emergence of the Omicron variant in late 2021, we saw a substantial increase in fulfillment network employees out on leave, and we continue to hire new employees to cover these absences.

As the variant subsided in the second half of the quarter and employees returned from leave, we quickly transitioned from being understaffed to being overstaffed, resulting in lower productivity. This lower productivity added approximately $2 billion in costs compared to last year. In the last few weeks of the quarter and into April, we've seen productivity improvements across the network, and we expect to reduce these cost headwinds in Q2. The last issue relates to our fixed cost leverage.

Despite still seeing strong customer demand and expansion of our FBA business, we currently have excess capacity in our fulfillment and transportation network. Capacity decisions are made years in advance, and we made conscious decisions in 2020 and early 2021 to not let space be a constraint on our business. During the pandemic, we were facing not only unprecedented demand but also extended lead times on new capacity. And we built toward the high end of a very volatile demand outlook.

Now that demand patterns have stabilized, we see an opportunity to better match our capacity to demand. We have lowered our operation's capital expenditures for 2022 and are evaluating other ways to increase our fixed cost leverage. We estimate that this overcapacity, coupled with the extraordinary leverage we saw in Q1 of last year, resulted in $2 billion of additional costs year over year in Q1. We do expect the effects of the fixed cost leverage to persist for the next several quarters as we grow into this capacity.

When you combine the impacts of the externally driven costs and the internally controllable costs, you get approximately $6 billion in incremental costs for the quarter. Approximately two-thirds of these costs are within our control, and with demand normalizing, we remain focused on rightsizing our cost structure and driving out any cost inefficiencies. Our guidance includes an expectation that we will incur approximately $4 billion of these incremental costs in Q2. We saw another strong quarter of innovation and customer engagement in the AWS segment, where net sales were $18.4 billion in Q1, up 37% year over year and now represent an annualized sales run rate of nearly $74 billion.

Developers at organizations of all sizes, from governments and not-for-profits to start-ups and enterprises, continue to choose Amazon Web Services. Companies like Telefonica, Verizon, Boeing, MongoDB, Amdocs, Bundesliga, Maple Leaf Sports and Entertainment, the NHL, and Thread announced new agreements and service launches supported by AWS. We also continue to build support infrastructure to best serve AWS' millions of customers. We recently completed the launch of our first 16 local zones in the United States with 32 more to come across 26 countries.

Local zones extend AWS regions to place our services at the edge of the cloud near large population, industry and IT centers, expanding our infrastructure footprint and enabling customers to build with single-digit millisecond latency performance. Last quarter, I provided some detail on our overall capital investments. So let me add to that with our current thinking. First, as a reminder, we look at the combination of capex plus finance leases.

Capital investments were $61 billion on the trailing 12-month period ended March 31. About 40% of that went to infrastructure, primarily supporting AWS but also supporting our sizable consumer business. About 30% is fulfillment capacity, primarily fulfillment center warehouses. A little less than 25% is for transportation.

So think of that as the middle and the last-mile capacity related to customer shipments. The remaining 5% or so is comprised of things like corporate space and physical stores. For full year 2022, we do expect infrastructure spend to grow year over year, in large part to support the rapid growth and innovation we're seeing within AWS. We expect infrastructure should represent about half of our total capital investments in 2022.

For the consumer business, as I said earlier, we currently have some excess capacity in the network that we need to grow into. So we've brought down our build expectations. I'd note again that many of the build decisions were made 18 to 24 months ago, so there are limitations on what we can adjust midyear. That said, we expect fulfillment dollars spent on capital projects to be lower in 2022 versus the prior year.

We also expect transportation dollars spent on capital projects to be flat to slightly down. Finally, I'll highlight a few additional items. We reported an overall net loss of $3.8 billion in the first quarter. While we primarily focus our comments on operating income, I'd point out that this net loss includes a pre-tax valuation loss of $7.6 billion included in nonoperating expense from our common stock investment in Rivian Automotive.

You may remember that we had a $12 billion gain on Rivian in Q4. We also provided our second quarter financial guidance as part of our earnings release. As a reminder, our comparable period of Q2 2021 included the continuation of extraordinary net sales growth through roughly the first half of that quarter. That began to moderate in the second half as vaccines became more readily available in many countries and people started getting out of their homes.

In addition, note that this year's Prime Day sales event will occur in the third quarter, in July to be specific. Last year, in 2021, Prime Day occurred in the second quarter. Prime Day contributed about 400 basis points to our Q2 2021 year-over-year revenue growth rate. Lastly, as you look at our Q2 operating income guidance, a reminder that we will see our seasonal step-up in stock-based compensation expense as our employees receive annual restricted stock unit grants in the second quarter.

This year, we expect to see stock-based compensation expense of approximately $6 billion, up from $3.3 billion in Q1, largely reflecting wage inflation as we continue to hire and retain employees in high-demand areas, including engineers and other tech workers. With that, let's move on to your questions.

Questions & Answers:

Operator

[Operator instructions] Our first question comes from Mark Mahaney with Evercore ISI. Please proceed with your question.

Mark Mahaney -- Evercore ISI -- Analyst

OK. Thanks. I'm going to ask two questions, please. In terms of the revenue guide for the June quarter, I think it sort of implies about 3%.

And if you look sequentially, if you look back at the last couple of years, the non-COVID years, the growth has been between 4% and 6%. Are you seeing signs of consumer softness or weakening? Is there any particular factor that would be -- cause your sequential growth to be lower than typical? And then briefly on the margins for Q2. So you got $4 billion in kind of these incremental costs versus $6 billion in the March quarter, but yet your guidance year over year implies kind of the same sort of year-over-year margin decline, about 500 bps. Could you just explain that a little bit? Thanks.

Brian Olsavsky -- Chief Financial Officer

Hi, Mark. How are you doing? On revenue, yes. The revenue guidance we've given is kind of our best view of what we're seeing right now. Customer demand does remain strong.

We're seeing, again, continued strength in Prime purchases, Prime commitment levels of usage -- benefits being used, etc. And the big part of the year-over-year comp is that we're comping the last part of the very elevated year-over-year step-up that lasted about half of last year's second quarter, and then we move Prime Day to Q3. So we're not seeing softness. We're cognizant of the current inflationary environment and the impact it has on consumer -- or excuse me, the household budgets.

A lot of times that is the time when people come to Amazon because they know we have great prices and selection and convenience. So it can go one of two ways. But we don't see any macroeconomic factors generally in this forecast on the demand side. We definitely see it on the cost side though.

Dave Fildes -- Director of Investor Relations

And Mark, I think your second question was related to the operating income guidance and some of the detail there. So as Brian said, it's the first time we've given the guidance for the second quarter, but he detailed a number of pieces. But like you said, expect to see, in aggregate, about $4 billion of pressure for the three buckets that Brian talked about: higher inflationary pressures, lower productivity and some fixed cost deleverage persisting into Q2. So that will be at some lower levels as we aim to and kind of expect to see some improvement in productivity, some of those other areas.

We're also committed to just generally reducing variable cost per unit and working to delever our fixed costs, specifically where we have those controllable cost buckets Brian spoke about. The other thing -- again, Brian mentioned it toward the end there of this opening [Inaudible] to see that seasonal step-up in stock-based compensation expense. So recall that our employees received those RSU grants in the second quarter. This year, we expect to see the expense of approximately $6 billion.

And so, that's up from about $3.3 billion in the first quarter.

Our next question comes from Justin Post with Bank of America. Please proceed with your question.

Justin Post -- Bank of America Merrill Lynch -- Analyst

Great. Thank you. Big picture. Amazon hasn't really been around during a period of high inflation.

How do you think about passing through the higher input costs through pricing? When you look at your units, they're flat and you're just not seeing any price increases in there. I know FX is a headwind, but how do you think about passing that through? And when can we start to see that? And then second question. It looks like your shipping costs are up 14% versus units flat. Probably makes sense with the input costs.

But we would expect some savings as you bring a lot of that transportation in-house, a lot of the delivery in-house. Are you seeing savings there? And how do you think about shipping costs versus units? Thanks.

Brian Olsavsky -- Chief Financial Officer

Sure. Let me make a comment on units first. If we step back, the first year of the pandemic from -- essentially from our world, from the middle of May 2020 to May 2021, we saw high growth. We went from a 20% growth rate in revenue to a 40% growth rate almost overnight and held it for a year.

And then, we started to lap that for the last year that will essentially end in the middle of this next month. And we -- so noted step-downs in the run rate as soon as the middle of May hit last year. So on the units though, units grew during that -- instead of jumping from -- to 40%, they jumped to the mid-40% to 50% range, mainly because of the product mix. People were buying a lot more gloves and cleaning agents and all the things tied to the pandemic.

So there's a lot of -- you have to look at the unit data with -- keeping that in mind because there's a mix -- heavy mix issue. But putting all that aside, you asked the question about transportation, shipping rates. Our shipping rates are very competitive, and we are seeing savings versus what we would get from external carriers. And it's beyond that.

We would not even necessarily have had the capacity to -- from external third-party providers to handle the transportation loads that we've seen in the last couple of years. So we're really glad that we have our -- we built our AMZL network. We would not be able to have a one-day program, same-day, one-day shipments if we try to deliver it with third-party shippers. It just would not be cost effective.

So what you're seeing there in the growth in shipping costs versus the unit growth, a little bit on the unit side, but essentially a factor of inflation and productivity that I've mentioned to you on the component that hits in the transportation area.

Dave Fildes -- Director of Investor Relations

And Justin, on your second point regarding inflation, of course, we've talked about we're not immune to inflationary pressures on the cost side. And with the ongoing supply chain disruptions and the start of the war in the Ukraine since our last quarter, we see larger impacts of inflation, some line haul shipping rates, fuel, shipping supplies and wages, which we talked about in some recent quarters as well. And we also see some volatility in utility pricing for some of the energy costs in operating the AWS data centers. Now when you look at cost for customers and sellers in terms of product pricing, I'd just reinforce our pricing philosophy hasn't changed.

We aim to offer low competitive pricing and try to stay on top of that pricing environment and make sure we're delivering a great price for customers. For our 1P business, that means continuing to be really competitive in that space with low prices relative to the reputable competitors out there and staying really close to that on the data. For third party, we don't control that price that's set by third-party sellers. So they're running their own businesses, and we'll adjust the pricing to account for inflationary costs in their environment as well.

And of course, on pricing and another -- other many other services with sellers, we offer services to help them not only handle with logistics but also get better pricing information to make sure that they're staying on top of that as well. So wherever we can help them, we do that. We did increase some fees effective, I believe, today related to the FBA sellers and some surcharge there. We're focused on, of course, addressing permanent costs and ensuring our fees are competitive versus those charged out there by their sellers.

But it's still unclear if the inflationary costs will go up or down and for how long they'll persist. So rather than a permanent fee change, we implemented that fuel and inflation surcharge for the first time. And it's, of course, a mechanism that's broadly used across the supply chain providers that are out there already, but it's the first time that we've done something like this.

Operator

Our next question comes from Brian Nowak with Morgan Stanley. Please proceed with your question.

Brian Nowak -- Morgan Stanley -- Analyst

Great. Thanks for taking my questions. I have two. First one, Brian, I want to ask you about one-day, same-day.

Now that you're getting inventory selection, SKU selection in some cases, back to where it was pre-pandemic, what are you seeing from a demand or an elasticity perspective as you get more inventory available for one-day, same-day? Is it really leading to incremental sales based on your data? And the second one, I want to ask about tech and content. It came in a little higher despite AWS costs coming in lower. Is there anything else we should sort of be thinking about in our modeling in tech and content, whether it's Kuiper or other items that are moving through that line item for the year? Thanks.

Brian Olsavsky -- Chief Financial Officer

Yeah. Let me start with your first question on one-day and same-day. Yes, we're approaching the service levels that we had pre-pandemic, and that's a positive sign. But this doesn't turn on a dime.

I think as a consumer, I noticed it myself, I see more things in stock. And it opens up the consideration set for things that I may have had to run to the store to get in a short period of time. And that trust -- and you see more and more that you trust it, and you continue to order. And you then go to Amazon first and say, OK, well, it's maybe my first stop before I even think about going to the store.

So it has to be built over time. It doesn't take years. It takes, hopefully, weeks and months. But we're hopeful and expecting that that will add to good elasticity, the same elasticity is that we start to see pre-pandemic.

Dave Fildes -- Director of Investor Relations

On the second point, the technology and content. Just as a reminder, the components in there is you got the Amazon tech and the AWS infrastructure, so everything from servers, network equipment, data center-related depreciation, rent utilities, those types of things, the AWS tech employee costs and costs to support the dot-com website and a number of other technology initiatives that we're working on. For Q1, it was up about 19% year over year, which was down a little bit less than what you see for year-over-year growth throughout 2021. That growth rate, though, does, of course, include an offset Q1 2022 related to -- a partial offset, I should say, related to the change in estimated useful lives for servers, which was a little under $1 billion of impact in the first quarter.

In terms of just the investment areas, I'd just reinforce it's continued investment in the tech infrastructure. One of the bigger pieces remains AWS, of course, there. And then, just broadly speaking, inclusive of AWS, the headcount to support the build-out and support that the AWS team is doing, as well as some consumer tech teams, Alexa and Echo devices and certain other areas there.

Operator

Our next question comes from Doug Anmuth with J.P. Morgan. Please proceed with your question.

Doug Anmuth -- J.P. Morgan -- Analyst

Thanks for the question. You talked about how you're no longer chasing physical or staffing capacity. And, in fact, you're actually running at an excess at the moment. So hoping you could talk a little bit about how long you think it could take to regain some of the productivity and cost efficiencies in the fulfillment network.

Thank you.

Brian Olsavsky -- Chief Financial Officer

Sure thing. Well, let me start with productivity. We began and ended the quarter with essentially 1 billion -- excuse me, 1.6 million employees, 1.6 million employees. Most of them, of course, are in operations.

During the quarter, we had a peak of 1.7 million, and we were able to work that down by the end of the quarter. So we have certain ability with contractors and all to adjust headcount. But for the most part, our employees are what we call blue badges or permanent Amazon employees. And now we work on getting productivity up.

It's a combination of productivity at the employee level, but it's also a matter of productivity of the -- and harmonization of the network, having the right demand in the right -- excuse me, the right capacity and the right demand matched at the warehouse level and the transportation node level. So that's what we're working on. And we've made good strides in the last month, and we're -- we see a line of sight to getting back, not all the way to pre-pandemic rates in the next quarter or two, but a good bit of the way. And that's what we're firmly focused on and working on, and that's in the warehouses and also in transportation.

Is there a second half to that question? OK. Go ahead.

Operator

Our next question comes from Eric Sheridan with Goldman Sachs. Please proceed with your question.

Eric Sheridan -- Goldman Sachs -- Analyst

Thanks for taking my question. I hope you're both well. Maybe if I could just stick on the capacity issues for a minute. In terms of the $4 billion number you're calling out, maybe the first part of the question would be, is that entirely the additional issues that are now front and center versus the issues we talked about from Q4 into first half of '22 from a logistics and supply chain standpoint, where we had talked about permanent versus transient cost nature of that $4 billion as you move through the first half of the year? So is this above and beyond that and above and beyond some of the lingering COVID costs that you had called out in prior periods? Just wanted to unpack some of the stack build of the $4 billion versus thing we already knew before.

And then, maybe following up on Doug's question and asking it a little bit differently. When you look out to the back part of the year, not asking for how you might guide, but there's a typical cadence to fulfillment expense build and employee build and headcount build into the back part of the year as you build the capacity toward the holidays. Will that have a very different cadence to it this year because you find yourself with this much excess capacity at Q1, Q2 versus prior years? Just so we can keep that front of mind. Thanks so much.

Brian Olsavsky -- Chief Financial Officer

Sure thing. Good questions, Eric. Let me start with the cost penalties. In Q4, we did mention $4 billion of cost penalties and drag on that quarter.

And $1 billion of that was fixed cost deleverage, principally a combination of having enough space and having super high leverage in the prior year when we were chasing volume and had less space. And we indicated that that would be carrying over into 2022, and it has. From a productivity standpoint, our issues in the second half of last year were different. They were -- we didn't have as much labor, even though we added, I believe, 200 -- I have it right here, 270,000 workers in the second half of last year.

We were chasing labor, and it was creating much disruption within our network. Long zone shipments, half full trucks, all kinds of negative consequences of not having labor. But we made it through Q4 with the anticipation that we'll be able to hold our labor for Q1 and labor certainty would be a lot better and certain in our network. That is still the plan, and we're probably a couple of months late on that because of some of the issues with Omicron in January.

And our reaction to it was that in an uncertain labor environment where a lot of people were out on leave, we hired more people and then found ourselves overstaffed when the Omicron variant subsided rather quickly, at least from our standpoint in warehouses. So the issue is switched from disruption to productivity losses to overcapacity on labor, and we believe that that will dissipate. It will take time in Q2, but it's -- so that's not the full -- we don't get the full $2 billion back in Q2, but we will make great strides on that. Inflation has been in both periods.

Inflation was in the transportation costs, especially in wage inflation last year. It remains there. It's been amplified a bit by the fuel costs following the Ukraine conflict, which has happened since we last spoke. So it's more a factor of -- those costs will now -- we believe, will persist a little longer than we were hoping at the beginning of the year.

And I mentioned some of the per unit rates for transportation, cargo shipments and also fuel costs. Those are real, and we have to find ways to offset those or use less of high-cost things like transportation and fuel. So we're working on that. As we progress -- there's only guidance for Q2.

But what we see is that the fixed cost deleverage will narrow as we go through the year, and we'll be really glad we have this capacity in Q3 when Prime Day hits because that's always a big surge of both inventory and orders and then definitely in the holiday season. So we will -- the way we see it is we've come out of a very tumultuous two years. We are glad we made the decisions we made over the past two years. And now we have a chance to more rightsize our capacity to a more normalized demand pattern.

So what's left there is really inflation, and that's what we're working on and evaluating and finding ways to mitigate and, in some cases, having to pass some of the costs through to third-party sellers as well so that we're not subsidizing sales there. And then, we will see. So we expect the year-over-year revenue comps to improve in the second half of the year because, again, we're passing this year of super high growth that I mentioned before from May of 2020 to May of 2021. But it's not like the volume has receded.

Like in Q1 literally, revenue was 61% higher over two years from 2020. So the way to think about it is it went up and stayed up, and now it's -- it will resume a more normal growth pattern. But I wouldn't be fooled by the revenue growth rates in this difficult comp period.

Operator

Our next question comes from Ross Sandler with Barclays. Please proceed with your question.

Ross Sandler -- Barclays -- Analyst

Hey, guys. So the letter mentioned some impacts post the Ukraine invasion. I'm guessing it's mostly on the inflation and the fuel costs you just mentioned. But any comment about how revenue trajectory compared in March after the conflict started versus before across your geographies? And is there any noticeable difference between Prime member volume and non-Prime? Thanks a lot.

Brian Olsavsky -- Chief Financial Officer

Yeah. Hi, Ross. No, I would say there's not a lot of Prime versus non-Prime differential. We had what we consider to be a very strong March.

It's very hard to compare year over year because March last year was the height of some stimulus payments in the United States. But from kind of a sequential period, we thought March was strong. So there's no indicators that we're seeing of weakness in consumer demand, but we're wary of it as probably all companies are because household budgets are tightened when fuel costs are doubling and a big part of your -- it ripples through food. It ripples through everything else.

So we're cognizant of that. But what we'll focus on is the customer experience, continue to get our delivery times to be better and increasing selection, which is better than pre-pandemic time period, and you're making the customer experience great on a lot of dimensions.

Operator

Our final question comes from Jason Helfstein with Oppenheimer. Please proceed with your question.

Jason Helfstein -- Oppenheimer and Company -- Analyst

Thanks. Two questions. Just can you talk about advertising a bit? Are you seeing supply chain disruption having any impact on advertising? Just any comments there? And then second, I don't think AWS backlog was asked, if there's any numbers you can share on AWS backlog growth this quarter versus last quarter. Thanks.

Dave Fildes -- Director of Investor Relations

Yeah, Jason, I'll take the second one first, just on the backlog. So yeah, I mean, we're continuing to see what the backlog is, right? It's the increase of AWS customers making long-term commitments for AWS. At the March period ended, we had $88.9 billion balance for that. So that's up about 68% year over year.

And the weighted average remaining kind of life term for those is 3.8 years.

Brian Olsavsky -- Chief Financial Officer

And on revenue -- excuse me, advertising revenue was up 25% year over year, and that's a strong run rate compared to the revenue growth rate. So we're still very happy and pleased with the way the advertising team is performing and how advertising has been valued by both sellers and vendors and others who use it to reach our customer base at the point where they're considering purchases. So a strong quarter and continue to roll out new and new products for sellers to manage their advertising and increase the ability to analyze and calculate the payback on marketing investments with us.

Dave Fildes -- Director of Investor Relations

Thanks for joining us today on the call and for your questions. A replay will be available on our investor relations website for at least three months. We appreciate your interest, and we look forward to speaking with you again next quarter.
