First-party cookie controls are changing

November 12, 2024

We're making some changes to how first-party cookies are managed in your AdSense account to simplify controls and improve your access to third-party demand.

What's changing?

We've combined the controls for enabling "first-party cookies" and "first-party cookies for personalization" into a single control. This means that turning on the new control will enable first-party cookies for the publisher, share it with demand sources, and enable all usages including personalization. The new control will be set to your existing personalization setting to aid the transition.

Sharing with Authorized Buyers

Currently, first-party cookies are shared with Google demand sources (Google Ads, Display & Video 360). Starting no earlier than December 4th, 2024, your first-party cookies will also be shared with Authorized Buyers. However, for the time being, this sharing will not include users in the EEA, Switzerland, UK, California, and some US states.

If you're already using first-party cookies for personalization, sharing with Authorized Buyers will be turned on by default. If you're only using first-party cookies without personalization, sharing will remain off.

For more information about these changes and how AdSense uses first-party cookies, visit Manage your ad serving settings.
