Coming soon

  • Deals Request-for-Proposal Improvements
    Ad Manager will soon be introducing enhanced RFP tools to help publishers take action on their deals revenue potential from buyer-initiated proposals. These new features will exist in a new RFP tab in the Proposals section of Ad Manager.  

  • "Video optimization" report metrics deprecation
    The "Video optimization" report metrics are deprecated. They were removed from the Ad Manager interface in July 2023, and will be removed from the external API in May 2024. See Video Solutions reports to learn about supported video reporting options.

  • Programmatic limited ads
    In the first quarter of 2024, Google will launch support for programmatic bidding on inventory eligible for limited ads. A publisher can enable this new serving mode to make use of invalid traffic detection-only cookies & local storage on both consented and un-consented traffic to enable demand from Google demand, Authorized Buyers, Open Bidding, and SDK Bidding in limited ads.
