Release notes for Google Ad Manager

What's new on June 1, 2021

Manage inventory

Traffic forecasts supported for cross-sell networks

Traffic forecasting numbers now include traffic from a cross-sell network’s partner site. For example, traffic is included. This allows forecasts to consider a more complete picture of your overall traffic.

Traffic and deliver ads

Enable all ad sizes for Ad Exchange line items

You can now easily allow all requested ad sizes for Ad Exchange line items. With the growth of multi-size requests and increased inventory from full-screen formats and native, this option provides a simple way to optimize demand and revenue. To get started, from the “Expected creatives” section of Ad Exchange line item settings, enable the All requested sizes slider. This is now available in both Google Ad Manager 360 and Google Ad Manager.

Fill more impressions with mobile fallback ads

Activating mobile fallback ads will maximize the likelihood of filling an impression opportunity. With fallback, Ad Manager will determine the eligibility of ads served through line items, rank them accordingly, and return a slate of ads, rather than just one.

Other product or Help Center updates

Federated Learning of Cohorts (FLoC) testing has begun

Chrome's Federated Learning of Cohorts (FLoC) public origin trial has begun. Ad Manager has started sending FLoC IDs on ad requests for a small percentage of traffic. This initial test will validate that our systems are operating as designed. There is no publisher revenue or performance impact expected. If you would like to opt out of Chrome's origin trial, set Permissions-Policy: interest-cohort=() in the HTTP response header during the origin trial.

  • Next step: Once Chrome begins adding more traffic to the test, the amount of ad requests that include FLoC IDs will increase.


Coming soon

  • Link your Google Analytics 4 properties to Ad Manager to see integrated app data  (Beta) 

    You can now link your Google Analytics 4 (GA4) properties to your Ad Manager network with Firebase using the Admin settings in Ad Manager. Publishers must first add the Firebase SDK to their apps in order to link their GA4 property to their Ad Manager network.  

    Use the new Analytics report to help you understand more about app user engagement across your Ad Manager network.

  • ATP declaration control for reservations is moving
    To improve user experience, the Declare ad technology providers for reservation creatives control will be relocated from the “EU user consent” page to the “Delivery” page in the Admin section. This change will not impact serving behavior.
  • New process for app review and approval
    In mid-2021, we will introduce a new process for reviewing and approving mobile apps that are newly linked to an app store. Once launched, all new mobile apps linked to supported app stores will need to be reviewed and approved to lift the ad serving limit. We recommend you claim your mobile apps as soon as they’re listed in an app store to avoid interruptions in ad monetization.
