Google Making Changes to Cookies used by AdSense for Search/Shopping & Programmable Search Engine. AdSense for Search/Shopping & Programmable Search Engine Cookie Changes.
Changes to AFS, AFSh, AFD and ProSE cookies
First-party cookies will be used as an alternative to current Google.com cookies when necessary.
Beginning as early as August 26, 2021, AdSense for Search, AdSense for Shopping, AdSense for Domains, and Programmable Search Engine will begin using a new “first party” (”1P”) cookie set within the context of your domain(s). This change is so that Google can continue to allow ad serving when third-party cookie usage is not possible due to restrictions on access to those cookies.
This new cookie will be used for spam protection and may be used for the purposes of experimenting on new features to improve the product. The intent of this change is to support improved user privacy in the context of an anticipated reduction in access to third-party cookies.
Publishers using these products will not be able to opt-out of this new functionality, since 1P cookies will be required in order to serve ads (in the absence of existing third-party cookies).
