Chrome plans to disable third-party cookies for 1% of users starting in early Q1 2024 with the eventual goal of ramping up to 100% starting in Q3 2024, subject to resolving any competition concerns with the UK’s Competition and Markets Authority (CMA). For an easier transition through the deprecation process we are offering a third-party deprecation trial which allows embedded sites and services to request additional time to migrate away from third-party cookie dependencies for non-advertising use cases.
If your site uses third-party cookies it's time to take action as we approach their deprecation. Chrome plans to disable third-party cookies for 1% of users from Q1 2024 to facilitate testing and then ramp up to 100% of users from Q3 2024. In this Cookie Countdown series, we'll guide you through the timeline and immediate actions you can take to ensure your sites are prepared.
