How will Google’s phasing out of third-party cookies in Chrome affect my tracking?

Google plans to phase out third-party cookies in Chrome by the end of 2024, in response to increasing concerns about user privacy. Testing started in January 2024, with third-party cookies restricted for 1% of Chrome users worldwide. By Q3 2024, all users will see these limits. 

This change will pose challenges for advertisers, especially when it comes to tailoring ads based on collected data. Here’s how it will impact your tracking and tag management in Piwik PRO:

  • Your web tracking won’t be affected as Piwik PRO only uses first-party cookies. Once Google makes the change, you won’t see any difference in collecting data from Chrome users. For more about cookies in Piwik PRO, see this article.
  • Some of the scripts, such as a Meta pixel or Google tag (gtag.js), that you’ve added through our Tag Manager may not function as expected because they rely on third-party cookies. This could lead to issues like incorrect campaign displays and difficulties in collecting campaign data. Unfortunately, there’s not much we can do about it as it’s up to those companies to develop alternative solutions for their pixels and tracking tags.

Here are some things you could do to navigate third-party cookie restrictions:
