As reported by AdWeek on May 8th, 2025 – just a week after emailing publishers asking them to adopt the new product – Amazon has killed their privacy program that would allow advertisers to better integrate with Google’s new Privacy Sandbox. This would have allowed advertisers using Amazon’s DSP to target users based on Google’s retargeting data. What does this mean for the future of cookie-less advertising and user data? Genius Monkey is here with the details and what advertisers need to know about user privacy going forward.
Google and the Privacy Sandbox
First, some context: Google had long planned on depreciating third-party cookies as a means of user data collection, and the advertising industry began looking for and adopting alternate methods of targeting users. Google itself began work on the Privacy Sandbox, a collection of tools designed to enhance user privacy by “reducing cross-site and cross-app tracking.”
One such tool was Google’s Protected Audience API (PAAPI) which would place users into interest groups, theoretically allowing advertisers to target relevant users without collecting or accessing individual data. While potentially beneficial to internet browsers, these tools have drawn ire from the advertising industry.
From its inception, the Privacy Sandbox was a controversial topic in digital advertising; for several years, the biggest names in adtech were consistently criticizing the initiative, citing untransparent event reporting, on-browser computing challenges, and much more. Eventually, Google announced that it would, in fact, NOT depreciate third-party cookies, rendering moot the main purpose of the Privacy Sandbox.
Amazon’s “New” Integration
Which brings us to Amazon; the e-commerce giant hosts its own DSP for programmatic ads and has been making moves to challenge the Trade Desk and DV360 for some time. Apparently, Amazon was testing an unnamed software API which would integrate the Amazon DSP with Google’s PAAPI, enhancing targeting while ensuring consumer protection.
According to AdWeek, Amazon had sent emails to select publishers inviting them to participate and test this new API. Mere hours after those invitations were sent, Google pulled the plug on third-party cookies. Nearly a year later, Amazon has confirmed that the new API is no longer being worked on, and plans to launch the software have been canceled.
And just like that, a major lifeline for the Privacy Sandbox – or at least a piece of it – is in the bin. While Amazon does not control the same amount of ad spend dollars as the other major DSPs, it nevertheless is considered a favorite by many advertisers. By withdrawing their support, Amazon has pounded another substantial nail into the Privacy Sandbox’s coffin.
Advertising in the Pre-Post-Cookie World
Google’s reversal on cookie policy has ups and downs; the adtech industry has invested heavily into cookie-less advertising in anticipation of Google’s depreciation, so many are understandably frustrated that their work has “been for nothing.” Meanwhile, ID providers and other publishers are thrilled that digital advertising can continue as it has been.
Or can it?
While the momentum of their exit has been severely arrested, cookies are still likely to go away eventually. New technologies are emerging and improving that offer better, more efficient means of advertising en masse. All that effort from the Adtech industry has created new advertising pipelines that still work in a world with cookies.
The controversial Privacy Sandbox isn’t quite dead, and it has taught the industry a very important lesson: there are MANY paths to getting messages in front of consumers. Google’s noncommitment has given advertisers even more options.
The Privacy Sandbox envisioned an internet where consumer privacy was a top priority. Now, the programmatic market is filled with cookie-filled and cookie-less buying options, and the power of privacy is mostly in the hands of the advertisers. Each brand or platform must decide for themselves the best policies for consumer privacy, and the industry is now poised to provide whatever balance they negotiate.
Take Genius Monkey, for example: our Meta-DSP system has never relied entirely on cookies for consumer data, and so the prospect of a world without cookies was never an issue for our users. With cookies back in play for the time being, the platform has even more options for finding the ideal route for our users. If an advertiser wants to go completely cookie-free in their approach, or they want to embrace cookies while they’re still around and relevant, the Genius Monkey platform will provide for those choices with the lowest prices in the industry.
