AdSense for Search and other Search Ads products will transition to new serving domains and eliminate ad personalization.

Starting November 2023, Google will transition its Search Ads publisher products from using 'google.com' as their' serving domain' to new domains. This change aims to improve end-user privacy and prepare products for changes to cookie behavior on web platforms. The products will no longer serve ads from 'google.com' and will no longer have access to shared cookies with Google properties. Ad personalization will be deprecated for these products, triggering no personalization controls. Publishers will not need to make any changes as the change is expected to have a minor impact on ad performance.
