Google has shifted direction again, announcing it will explore a "new path" around online privacy rather than deprecating third-party cookies in Chrome. This dramatic halt comes after more than four years of promises and delays, as its cookie-free vision continued to face resistance across multiple layers of the advertising ecosystem.

For marketers who have long viewed cookies as the cornerstone of digital marketing, this reprieve may be welcome, but the move is likely to shake the growing alternative ID space. Meanwhile, although consumers and regulators have yet to weigh in, with cookie-free spaces such as connected TV (CTV) and mobile continuing to expand, the practical impact of this decision may be limited.

"This news has sent ripples through the industry. While it may seem like a breather for advertisers heavily reliant on cookie tracking, the industry's direction toward enhanced privacy and user consent has not changed," said Marçal Serrate, Director of Data Technology at Azerion, in an email comment.

Google did not detail the specifics of the new path, but said it is discussing this "new path" with regulators and will communicate progress with the industry. The company will continue to provide and invest in its proposed cookie alternative, the Privacy Sandbox API, while planning to introduce additional privacy controls, such as IP protection in Chrome's Incognito mode.

"We are proposing an updated approach that elevates user choice. Instead of deprecating third-party cookies, we would introduce a new experience in Chrome that lets users make an informed choice that applies across their web browsing, and they can adjust that choice at any time," said Anthony Chavez, Vice President of Google's Privacy Sandbox, in ablog post."

It remains unclear whether Google will choose an "opt-in" or "opt-out" mechanism for continued cookie use, leaving advertisers in deeper uncertainty. By comparison, Apple launched its App Tracking Transparency (ATT) framework in 2021, requiring consumers to opt in to app tracking.

Since then, consumer opt-in behavior has evolved: according toAppsFlyer data, 50% of users globally now opt in to ATT tracking, up 10% from its launch. If Google decides to continue cookie use on an "opt-out" basis, consumers may see pop-ups similar to those common under the EU's General Data Protection Regulation (GDPR).

"Expect more annoying EU-style pop-ups on every website. That's bad for user experience, but it will satisfy regulators on both sides of the Atlantic," said Rio Longacre, Managing Director of Advertising and Transformation at consulting firm Slalom, in an email comment.

Winners and losers

Google first announced in 2020 that it would end support for cookies, a key technology in digital advertising, but has repeatedly delayed its plans, most recently postponing the timeline in April. Throughout the process, advertisers, publishers, the ad tech industry, trade bodies—and perhaps most importantly, regulators such as the UK's Competition and Markets Authority and the Information Commissioner's Office—have expressed concerns that removing third-party cookies would disrupt the digital advertising industry and give Google too much control. The widespread opposition makes Google's latest decision more of a mild surprise than a true shock.

"I don't see this as a significantly game-changing announcement," said Loch Rose, Chief Analytics Officer at Epsilon, in an email comment. "The expected outcome is essentially the same—the only difference is that more users may now choose to keep third-party cookies rather than having Google force the change, so it's just another step in the journey."

The journey toward a cookie-free future will still continue, especially as the advertising industry has already invested countless time and money in privacy solutions,despite Google's multiple previous delays. Moreover, the continued growth of cookie-free channels such as CTV makes the post-cookie environment an inevitable part of the advertising industry, regardless of Google's plans.

"Much of the preparation work for a cookie-free future will still apply to omnichannel advertising," said Grant Parker, President of personalization platform Flashtalking by Mediaocean, in an email comment. "As privacy regulations continue to evolve, focusing on consumer choice and consent remains critical."

Much of the work done by vendors developing alternative IDs aims to enable tracking or targeting in a privacy-safe manner. Google's announcement may accelerate the shakeout in this space, which has already seen a few strong competitors emerge.

"Looking ahead over the next year, they may all die out except for a few major identity backbones. My guess is that we'll end up with just the walled garden IDs, plus The Trade Desk's UID2 and LiveRamp's RampID," said Slalom's Longacre.

AI and regulation still in play

While this news may lead to a reckoning for alternative ID vendors, not all ad tech providers are in the same position: vendors offering cookie-based solutions to advertisers may see new opportunities, especially when combined with the hottest AI technology of the moment.

"In the coming months, I expect to see a wave of new advertising solutions leveraging AI to analyze cookie data for better customer targeting," said Eli Goodman, CEO of Datos, a clickstream data company under Semrush, in an email comment.

Meanwhile, potential regulatory and legislative actions continue to pressure Google's moves and the future of online advertising. Although privacy legislation in the form of the American Privacy Rights Act is againunlikely to get a congressional vote, the Supreme Court's recent ruling on the "Chevron doctrine" has made the rules for internet privacy regulation even more ambiguous.

As advertisers await Google's new path plans to take shape, they may still need to contend with the ongoing signal loss already affecting consumer tracking and ad targeting. According to Andrew Richardson, Senior Vice President of Analytics and Measurement at digital marketing agency New Engen, more than half of U.S. consumers use mobile browsers that block cookies, and over 30% use ad blockers.

"Brands and agencies may feel relief at this news, but they shouldn't let their guard down. Even without this change, signals have been steadily eroding," Richardson said in an email comment. "As an industry, we need to prioritize consumer privacy and adapt to a cookie-free world, rather than trying to circumvent the inevitable decline of these signals."
