For the last five years, marketing teams have been rewriting the playbook…testing clean rooms, modeling first-party data, and preparing for a future without third-party cookies. But with Google and Amazon both hitting pause, the path forward just got murkier. Again.
After encouraging publishers to adopt its integration with Google’s Protected Audience API (PAAPI)—one of the core solutions within Privacy Sandbox—Amazon has reversed course. The company confirmed it no longer plans to integrate PAAPI into its demand-side platform.
For publishers and ad tech partners, the message is clear: Amazon is pivoting away from this version of the cookieless future.
So what does that mean for brands?
We believe this move isn’t just tactical, it’s a reflection of a deeper truth emerging in 2025: marketers are no longer chasing “what’s next” in privacy, they’re waiting to see what sticks.
A Cookieless Future, Delayed Again
Google introduced PAAPI as one of several tools meant to maintain relevance in advertising without using individual identifiers. It grouped users into interest categories, allowing browsers to handle targeting decisions locally. Rather than following individuals across sites, it allowed ads to target general categories within the Chrome browser itself. In theory, it was meant to preserve relevance while protecting anonymity. In practice? Adoption has been slow, and performance signals have been unclear.
Amazon, through its Publisher Services division, was preparing to support PAAPI in its DSP. Ahead of Google’s pivot, Amazon had been preparing to launch PAAPI support in its DSP, with internal communication indicating a phased rollout. But after Google’s sudden decision to pause cookie deprecation yet again, Amazon pulled the plug on its PAAPI rollout.
On the surface, this may look like a canceled test. But zoom out, and it’s something bigger: a symptom of fractured trust in privacy-first replacements.
When the Industry’s Plan Becomes the Backup Plan
The cookieless roadmap has been in motion for over five years. Billions of dollars in engineering effort have been poured into preparing for this shift. But advertisers are pragmatic, and what we’ve seen from both the buy and sell sides is a growing reluctance to fully commit to solutions that feel experimental, fragmented, or uncertain.
Amazon’s reversal reflects that reality.
According to publisher sources, advertiser demand for these new signals was minimal, making it difficult to generate meaningful scale or budget allocation within Amazon’s DSP environment. Advertisers weren’t activating. The signal lacked transparency. And with cookies still active, there was no urgency to shift meaningful budgets.
This isn’t a failure of technology, it’s a failure of incentive.
Without clear performance, simplified execution, or scaled adoption, these privacy workarounds become just that: workarounds.
So Where Does Amazon Go From Here?
Despite shelving its PAAPI integration, Amazon isn’t stepping away from cookieless innovation altogether. Its focus now returns to its own first-party tools, including Amazon Publisher Cloud, Ad Relevance, and Signal IQ, which help advertisers activate against Amazon’s rich data ecosystem without relying on third-party cookies.
And that’s where Amazon continues to lead.
Unlike other platforms still dependent on browser behavior, Amazon operates in a logged-in, high-intent environment, one that’s anchored by purchase data, not just browsing history. With the right signal clarity and measurement framework, brands can still achieve personalized performance at scale, without needing the browser to mediate.
What This Means for Brands
For brands caught in the crossfire of shifting timelines and tech standards, here’s the north star: don’t chase headlines, build with platforms that already deliver results. You don’t need to predict what’s next. You need to invest where outcomes are proven.
The truth is:
- Cookies aren’t gone. But they’re fading.
- Privacy-first solutions are evolving but not yet unified.
- First-party data, clean rooms, and closed-loop measurement are still the highest-performing playbooks available today.
Amazon’s retreat from PAAPI is a reminder that not all innovations are ready for primetime, and that retail media’s power lies in platforms with persistent identity, not in replacing what’s broken with what’s brittle.
Focus Where the Signal Is Strong
Marketers don’t need more disruption. They need more direction.
In 2025, that means investing in retail ecosystems that deliver consistency, transparency, and control. It means aligning with platforms that aren’t guessing where the customer is going but already there, with signal-rich insight and scalable infrastructure.
Amazon’s move away from PAAPI isn’t the end of the cookieless conversation. But it is a moment to pause, refocus, and ask the right questions because change is constant, results don’t have to be.
