Ad Manager Certified External Vendors

Ad Manager enables you to use third-party ad technology vendors for various functions identified here . Some technologies can prevent unwanted vendors from running on your site, while others may increase demand flowing through the system.

Third-party vendors undergo a business review. Google does not verify or guarantee the technical implementation of these vendors.

There are two types of allowed vendors on this list.

No declaration neededThese vendors do not need to be explicitly declared ('No' in the declarable column below).

Declaration neededThese vendors need to be declared ('Yes' in the declarable column below), in the RTB BidResponse . This is typically because the technology needs publisher implementation to work (e.g., expandables), or it could be disruptive to a publisher's pages.

The following vendors can serve third-party ads on the Google Ad Manager platform in all regions unless otherwise noted below.

Please note which vendor is allowed as a third- or fourth-party call. Please also note that, while this list is being constantly updated, we do not guarantee that product offerings, platforms or vendor types are fully up to date. You should always reference our specification pages to ensure the ads you want to run are in-line with the latest requirements, and you should contact the vendor directly to find out about their latest products.
