Introducing "Authorized Buyers" — a replacement for the "Ad networks" blocking control

Starting November 6, 2025, we'll be removing the "Ad networks" blocking control from Brand safety and adding a new "Authorized Buyers" blocking control. This new control won't include any inactive ad networks, test ad networks, or Display & Video 360 (DV360) networks. As part of these changes, we'll also remove the "Automatically allow new Google-certified ad networks" control. Going forward new authorized buyers will be allowed by default.

Note that your existing blocked ad networks won't change, and no action is needed from you.

What controls are available on the new "Authorized Buyers" page?

As a reminder, authorized buyers have programmatic access to "Google Partner Inventory", which includes trusted ad inventory from publishers and developers who use Google Ad Manager, AdMob and AdSense, in an ad exchange environment. The most common authorized buyers include ad networks, trading desks, and demand-side platforms (DSPs).

On the "Authorized Buyers" page you can allow or block certain authorized buyers from bidding on the inventory on your site. You will also have better visibility into the parent-child relationships between authorized buyers and more control over them.

Timeline

We're launching these changes starting November 6, 2025.

Until the launch

• You can still use the "Automatically allow new Google-certified ad networks" control. If you currently have this control turned off, you might want to turn it on now to get used to the upcoming change.
• You'll still be able to change the status of ad networks under Blocking controls > Ad networks. Any changes you make until the final day of the launch will be preserved and visible under Blocking controls > Authorized Buyers.
• You can access a view-only version of the "Authorized Buyers" page to familiarize yourself with the controls. To access the page:
  1. Sign in to your AdSense account.

  Note: You won't be able to use these controls until after the launch.
