Outcome-based Turtledove

It might have been delayed, but the end of third-party tracking cookies is coming at the beginning of 2025, and businesses can’t afford to keep pretending otherwise. The good news is that thanks to this delay, there is still a small window of opportunity for companies to prepare for the cookieless future by engaging with the Google Chrome Privacy Sandbox.

In January 2020, Google announced that it will end support for third-party tracking cookies in the Google Chrome browser “within two years,” signifying major changes for retargeting Google Ads. In June 2021, this timeline was extended to 2023, June 2022 brought yet another extension to the 2nd half of 2024, and in April 2024 it was postponed to the beginning of 2025. Moreover, Google Chrome declared withdrawing 1% of 3rd-party cookies in Q1 2024 to provide a reliable environment for testing.

Other browsers, such as Safari, Firefox, and Edge, have already stopped supporting 3rd party cookies for retargeting ads. But from the marketer’s point of view, the fact that Google will also follow this trend for retargeting Google Ads is important due to Chrome’s over 60% market share. Therefore—how will retargeting work without cookies?

We have previously presented what users will see in a cookieless future, what products will be displayed, and the end results—the visible consequences of the proposed changes to third-party cookies.

In this article, we would like to focus on what is happening behind the scenes.
