Google & Criteo Partner on Retail Media – How the First Retail Ad Network Paved the Way
Retail media can make for strange bedfellows, as evidenced by this week’s announcement that Google and Criteo are joining forces. In a move few anticipated, Criteo has become Google’s first-ever third-party partner for on-site retail media inventory. In plain terms, advertisers using Google’s Search Ads 360 (SA360) platform will soon be able to buy sponsored product ads on over 200 e-commerce and retail sites in Criteo’s network – all through the Google interface. This partnership is a landmark moment in the evolution of retail media. For those of us at TravelSpike, it also feels like a full-circle moment: we pioneered the concept of a retail media network over two decades ago, long before it was a $200+ billion industry buzzword. In fact, TravelSpike launched the first vertical online ad network way back in 2002 – a full 10 years before Amazon’s foray into retail media. Now, as Google and Criteo take retail media to new heights, it’s worth examining how we got here and why this unlikely alliance is so significant.
First Movers: TravelSpike’s Retail Media Vision in 2002
Today everyone talks about “retail media networks” as the hottest thing in advertising. But in the early 2000s, the idea of a vertical ad network dedicated to a specific industry was revolutionary. TravelSpike was a trailblazer on this front. In 2002, we created our Travel Ad Network® service – the first and largest online ad network focused exclusively on the travel, tourism, and hospitality sector. This was a bold departure from the broad, unfocused ad marketplaces of the dot-com era. Our approach was simple yet ahead of its time: aggregate high-quality travel audiences across numerous websites and offer advertisers a one-stop shop to reach those travelers with targeted campaigns. By diving deep into a niche (rather than casting a wide, generic net), TravelSpike demonstrated the power of contextual and audience-specific advertising early on.
That first-mover advantage wasn’t just a historical footnote – it laid the groundwork for what would eventually be called “retail media.” In those early days, we saw tremendous success connecting travel brands with travelers in the right moments. Our network grew to include hundreds of travel publishers and reached millions of users. And notably, the industry took notice. Even Criteo, in its infancy as an ad-tech upstart, was among the many buyers leveraging our Travel Ad Network to access travel audiences. This was long before Criteo became a household name in ad tech; back then, it validated our model that niche audience networks could unlock valuable demand. We didn’t call it “retail media” in 2002, but the concept was the same: leveraging first-party data and purchase intent in a specific vertical to drive targeted advertising. TravelSpike was doing commerce media in travel before the term existed.
Amazon’s Entry Validated the Model
Fast-forward a decade to 2012, and the concept of retail-focused ad networks hit the mainstream in a big way. That year, Amazon launched their own online retail media network on a major scale. Amazon’s move proved what we at TravelSpike knew all along: when you connect advertising to the point of purchase, magic happens. By offering sponsored product placements on its e-commerce site, Amazon unlocked a new gold mine of ad revenue beyond its core retail business. In fact, Amazon’s advertising division grew so explosively that, by the mid-2020s, it was pulling in over $30 billion a year from ads – a stunning figure that made the rest of the industry sit up and take notice.
Amazon’s success kicked off a retail media boom across the industry. Other retail giants like Walmart, Target, and Kroger rushed to launch their own media networks, selling ad placements on their websites and apps. By turning their first-party shopper data and websites into advertising platforms, retailers opened a lucrative new revenue stream. Analysts dubbed the 2020s as the era of retail media, and they’re not exaggerating – retail media ad spend has skyrocketed. In 2019, U.S. retail media spend was around $13 billion; by 2022 it had jumped to over $40 billion, and it’s projected to keep climbing. Globally, forecasts peg retail media at roughly $300 billion by 2030, which would be about 20% of all advertising spend.
This wave of growth validated the model TravelSpike championed years prior: advertising that is tightly integrated with commerce is incredibly effective. When ads appear where consumers are shopping or researching (whether on an e-commerce site or planning a trip), advertisers get closer to the “bottom of the funnel” – reaching high-intent buyers. Amazon proved it at massive scale, and every retailer with web traffic and customer data now wants in on the action. The result is an increasingly fragmented landscape of retail media networks at various retailers and marketplaces. Brands and agencies, meanwhile, are allocating more of their budgets to these channels to chase that high-intent audience and measurable ROI. This brings both opportunity and complexity – which is exactly why the Google–Criteo partnership is so intriguing as the next stage of retail media’s evolution.
Google + Criteo: An Unlikely Alliance in 2025
That brings us back to the news of the moment: Google’s Search Ads 360 platform integrating Criteo’s retail media network. On the surface, this is a partnership few would have predicted a few years ago. Google – the world’s largest ad company – historically kept a tight grip on its ecosystem. Criteo – a French ad-tech firm famous for retargeting – was, in some respects, a competitor that often operated outside of Google’s walled garden. And yet, here they are, joining forces. Criteo announced it is now Google’s first on-site retail media supply partner, meaning Criteo’s network of over 200 retail and e-commerce partners is plugged into Google’s SA360 platform. Strange bedfellows indeed – but strategic ones.
What exactly does this integration do? In practical terms, it lets advertisers using Google’s SA360 (which many large brands use to manage search campaigns) seamlessly extend their campaigns onto retail sites in Criteo’s network. Previously, if an advertiser wanted to run ads on, say, BestBuy.com or Target.com via Criteo’s network, they’d have to manage that separately from their Google search buys. Now, Google is saying: “You can do it all through our interface.” An SA360 user can allocate budget to sponsored product listings on retailer sites alongside their Google Search and Shopping Ads. This bridges the gap between search marketing and retail media in a frictionless way. It essentially brings those retail media placements into the same workflow and reporting as Google’s own ads – a huge convenience for advertisers looking to scale across channels.
Why would Google do this, and why now? The short answer: to capture the massive retail media opportunity and keep advertisers inside the Google ecosystem. As noted, retail media spend is booming, but much of it has been flowing to a few dominant players – chiefly Amazon. Google doesn’t want to lose search ad budgets to Amazon or even to retailers’ standalone networks. By incorporating Criteo’s inventory, Google can offer brands one-stop shopping for search and retail media. It’s a play to “level the playing field” and ensure ad dollars don’t leave for Amazon by providing comparable reach across many other retailers. From Criteo’s perspective, the partnership unlocks a flood of new demand – all those search advertisers who otherwise might not have considered or bothered with retail media outside Amazon can now easily access Criteo’s 200+ retailers. It’s a win-win: Google retains more ad spend within its platform, and Criteo gains a firehose of budget and visibility it could never reach on its own. As Sherry Smith, Criteo’s retail media head, put it, “these are budgets that typically have stayed outside of retail media” until now. In other words, big advertisers that mainly spent on Google and traditional search can now dip into retail media without leaving Google’s toolset – a seamless expansion of their strategy.
Beyond pure dollars, this alliance also addresses a pain point in retail media advertising: measurement and fragmentation. Brands have been clamoring for unified measurement across different retail media networks – something that’s been hard when every retailer runs its own siloed program. Google’s integration with Criteo promises unified, closed-loop measurement through SA360, so advertisers can directly see how their retail site ads translate to sales and outcomes. That’s a big deal. It means more transparency and confidence in retail media performance, which in turn should attract larger budgets to those networks.
It’s worth noting how unprecedented this collaboration is. Google rarely partners with other ad platforms in this manner, especially for inventory access. The fact they’ve done so with Criteo signals just how critical retail media has become – and perhaps a recognition by Google that it can’t go it alone if it wants to challenge Amazon’s dominance. Industry watchers have pointed out that Google is facing regulatory pressure to open up its ecosystem and play nicer with others, especially after recent antitrust scrutiny of its search business. Whether motivated by regulation, opportunity, or a bit of both, Google is effectively bending its long-standing walled-garden approach. The result is a more interoperable environment – one where a marketer’s journey from Google search ad to a retailer’s sponsored product ad is a lot more fluid. We see this as a sign of the maturing retail media landscape: early phases were about each big player building its own network; now we’re entering an era of integration and collaboration, where even giants team up to better serve advertisers and publishers.
Why This Partnership Matters
The Google–Criteo partnership is more than just another press release – it’s a bellwether for where commerce-driven advertising is headed. Here are a few key reasons this development matters:
- A United Front Against Walled Gardens: By teaming up, Google and Criteo are implicitly pushing back against the one-player dominance of Amazon in retail media. Rather than each trying to build a lesser copy of Amazon’s ad platform, they’re combining strengths. This could foster more competition and diversification in the retail media space, which is healthy for brands and retailers alike. A more level playing field means smaller retail players get access to big budgets, and advertisers aren’t forced to spend only in one or two ecosystems.
- Simplified Access for Advertisers: One of the challenges marketers faced as retail media networks proliferated was operational complexity. Every network had its own platform, metrics, and learning curve. By plugging Criteo into SA360, Google is simplifying the workflow. Search marketers can now reach high-intent shoppers on dozens of retail sites without leaving the familiar Google Ads environment. This ease-of-use will likely entice more advertisers to extend into retail media who might have been hesitant to juggle multiple platforms.
- Closing the Loop on Measurement: The integration brings closed-loop measurement to the forefront. Advertisers will get a more holistic view of performance – from the initial search click to the eventual purchase on a retailer’s site – all in one dashboard. That unified reporting is crucial. It enables smarter optimization and budget allocation based on real sales impact, not just ad clicks. As return on ad spend becomes clearer across channels, expect advertisers to double down on those retail media placements that prove their worth.
- Retailers Empowered (With Guardrails): Interestingly, Criteo’s retailer partners aren’t being lumped into a free-for-all. Retailers maintain control over which ads and brands appear on their sites, even with this new influx of demand. Criteo has set up guardrails to prevent, for example, too many ads crowding a page or irrelevant products showing up. This selective opt-in model means retailers get the benefit of more monetization without sacrificing user experience or autonomy. In the long run, that makes retailers more willing participants in aggregated networks like Criteo’s.
In short, this partnership signals that retail media has graduated from a fragmented novelty to a collaborative ecosystem play. The lines between search advertising and e-commerce advertising are blurring. We anticipate this is just the beginning – more such alliances or integrations could follow. (It wouldn’t surprise us to see other DSPs or ad platforms strike similar deals to tap into retail media dollars.) The industry is moving toward a place where advertisers can mix and match channels and inventory sources fluidly, guided by data and results rather than by platform silos. That’s a vision we wholeheartedly welcome, as it echoes the integrated approach TravelSpike has championed for years.
Full Circle: TravelSpike’s Legacy and Future Outlook
For TravelSpike, watching Google and Criteo partner up is a gratifying validation of the path we helped pave. Our legacy as the first retail ad network (even if it was “just” travel back then) was all about recognizing the value of vertical integration – connecting advertisers to consumers at the moment of decision. Seeing the titans of tech now embrace that philosophy, and even emulate it through partnerships, reinforces our belief in specialization plus collaboration. It feels a bit like the industry is catching up to the vision we had in 2002.
It’s also personally satisfying to reflect on how far the ecosystem has come. There’s some pride in remembering that years ago, Criteo was a client tapping into our inventory to reach travel intenders – and today Criteo is leading the charge with Google to bring retail media to the masses. The innovators of yesterday have become the power players of today, and they’re carrying forward principles that were core to TravelSpike’s early success. Of course, innovation never stops. Just as we led with the first retail ad network, we’ve continued to push boundaries in how data and technology can make advertising smarter and more effective.
One example is our Travelogic™ platform, a proprietary AI-driven targeting and optimization engine. Travelogic™ crunches decades of campaign data (we’ve run over 10,000 campaigns) to spot patterns in traveler behavior and ad performance. It essentially “pre-optimizes” campaigns before launch, using machine learning to ensure the right travelers see the right offers at the right time. This kind of intelligence is what sets successful vertical networks apart. Whether it’s 2002 or 2025, the game is won by understanding your niche audience deeply and leveraging data to serve both advertisers and consumers better. That is TravelSpike’s bread and butter. And in an era when first-party data and privacy are paramount, our long experience with consent-based, context-rich targeting (versus the old spray-and-pray of third-party cookies) gives us a strategic edge.
So, what does the Google–Criteo news mean for us and for you? It means the rest of the advertising world is waking up to what we’ve believed for a long time: partnerships and niche expertise drive superior outcomes. It’s a reminder that even in a hyper-tech, AI-driven ad landscape, the fundamentals remain – know your audience, meet them where they make decisions, and collaborate to create win-win scenarios. TravelSpike will continue to do exactly that. We’ll keep forging strategic partnerships, investing in our technology, and expanding our network in ways that benefit our clients. The retail media revolution is not slowing down, and neither are we.
The evolution from TravelSpike’s humble “travel ad network” in 2002 to a world of interconnected retail media giants in 2025 is truly remarkable. What started as a novel idea in a specific vertical has become a $100+ billion juggernaut reshaping digital advertising. Google and Criteo’s partnership is the latest proof that our industry has evolved — and is still evolving — in the direction we anticipated. It’s a journey of legacy and innovation: legacy, because pioneers like TravelSpike planted the seeds that have grown into today’s retail media forests; innovation, because the players in this space (big and small) continue to find new ways to collaborate and compete.
As we witness these developments, our tone is confident and optimistic. TravelSpike has been here from the beginning, and we’re more than ready for what’s next. Whether it’s leveraging our Travelogic™ data intelligence to maximize campaign ROI, or partnering with emerging platforms to broaden our reach, we’ll remain at the forefront of this ever-changing landscape. Google and Criteo’s bold alliance underscores one thing: the future of advertising belongs to those who can adapt, partner, and think vertically. That’s exactly how TravelSpike has operated for over 20 years. We’re excited for this new chapter in retail media – after all, we helped write the book.
TravelSpike pioneered retail media in 2002. Let’s put that 20+ years of innovation to work for your campaigns.
