Release notes for Google Ad Manager

What's new on October 19, 2020

Manage inventory

Improved Dynamic Allocation

Over the next few weeks, we’ll be releasing improvements to dynamic allocation that automatically increase a publisher’s revenue from remnant line items without impacting the delivery of guaranteed line items. Dynamic allocation works best when remnant line items have CPMs or CPCs that accurately reflect their true value.

Traffic and deliver ads

Traffic web interstitials (Beta) 

You can now traffic full-page web ads that appear between page views. Web interstitials serve as an additional inventory and revenue source. Publishers can monetize web pages with impactful ads while respecting Better Ads Standards.

Add terms & conditions and a no-pause agreement to a proposal

As part of the negotiation process with a buyer, you can now add your own terms and conditions to a Programmatic Guaranteed proposal and also agree to not pause delivery.

  • Terms and conditions specify the contract details of a proposal between the publisher and a buyer. These are custom terms and conditions that the publisher has an option to create. They’re not required and have no relationship to Google’s terms and conditions.
  • You and the buyer can agree that neither party will pause a proposal once it’s delivering. It’s helpful to both publishers and buyers to make this agreement because it sets clear expectations about whether you want to allow pausing. It also acts as a reminder to not pause unnecessarily.

Target more ad formats

You can now target the following formats in line items and pricing rules for even more control in reaching your intended audience:

  • Line items: You can target interstitial and anchor ads.
  • Pricing rules: You can target interstitial, rewarded interstitial, app open, and anchor ads.

Manage network settings

Improved security with SafeFrame random domains

On October 26, the "Default" for SafeFrame security will be set to load creatives from randomized subdomains. This is the strongest available security guarantee, used to further isolate SafeFrame content. To protect against a known security vulnerability, we recommend you test and enable unique SafeFrame domains.

Other product or Help Center updates

Additional ad technology providers for LGPD

On November 16, newly certified Ad Technology Providers (ATPs) will become available for use with the LGPD. Review the “Upcoming changes” section of Ad Technology Providers for the LGPD to learn more about these new ATPs.

Implementation Grace Period 0 for TCF v2.0

Beginning the week of October 19, 2020, ad requests with Grace Period 0 errors will transition to non-personalized ads (NPA).

About the SDK instance ID

With the latest versions of the GMA and IMA SDKs, a rotating SDK instance ID is automatically generated for each app to ensure effective delivery, display, and integrity of ads. The SDK Instance ID is unique per app and helps maximize your app’s ad performance. Learn more about preparing your app for iOS 14+.


Coming soon

  • Updates to backfill management
    On November 2, 2020, the ability to link multiple Ad Manager accounts will be replaced with new ways to discover and implement features. Requests to link additional Ad Manager and Ad Exchange accounts will be reviewed by the Ad Manager team to identify a best-fit solution. Publishers that have not used this feature since January 2019 will no longer be able to link new Ad Exchange accounts.

    This change only affects new account link requests. If you have already linked Ad Exchange accounts, this change does not affect those existing links.

  • Updates to app claiming process
    We are making improvements to the process to claim apps for targeting. This includes claiming published apps from multiple supported 3rd party app stores. The app name and status will be shared with AdMob and Ad Manager.
