Have you enabled first-party cookies with your pixel?
You probably heard that Chrome started limiting third-party cookies on January 4th. Google’s goal is to eliminate all third-party cookies by the end of 2024. Considering 60% of internet users are on Chrome and Safari already took this step, third-party cookies are likely to be phased out this year.
Meta hasn’t been clear about how they use third-party cookies, but there is one step that you can take: Enable first-party cookies with the pixel.
Do the following:
- Within Events Manager, go to Data Sources
- Select your pixel and go to the Settings tab
- Scroll down to Cookie Usage
- Turn on first-party cookies if you haven’t already
Meta is pretty cryptic about what exactly this does (the benefits of first-party cookies with the pixel vs. third-party cookies and vice versa), but first-party cookies aren’t part of this Chrome update.
When possible, you’ll want to leverage first-party data going forward. That includes passing events using the Conversions API and turning on first-party cookies with your pixel. While this won’t necessarily solve all data loss resulting from the elimination of third-party cookies (we still aren’t clear what this looks like), this puts you in a better position.
