Release notes for November 4, 2019

New recommended GPT passback snippet

There is now a new recommended snippet for creating GPT passbacks. Use of definePassback() and defineOutOfPagePassback() is discouraged, since these functions behave synchronously and may be blocked by certain browsers. If you want to use a passback from a 3rd party ad server, use a standard Google Publisher Tag written into an iframe. Learn more

Traffic and deliver ads

COPPA controls for line items

Starting in November, a control that allows you to specify whether a line item is safe to serve on child-directed requests or not will be introduced. The "Child-directed ads" setting in Ad Manager helps you comply with the Children’s Online Privacy Protection Act (COPPA). Learn more about COPPA

Although available in November, there's no impact on ad serving until January 2020. Become familiar now with this setting and COPPA to ensure your network is configured to comply with the law. Learn more

View experiment results in a new table format

We’ve introduced a new viewing format to help you understand your experiments better. You can now toggle between chart and table formats when reviewing experiment results. All values are rounded for both views.

Yield Partners dashboard generally available

Use the Yield Partners dashboard to evaluate the performance of Open Bidding Yield partners to make better informed decisions when structuring and targeting Yield groups. The Yield Partners dashboard is now generally available from the Home page in Ad Manager. Learn more

Changes to counting methodology for “Total code served count” and “Unfilled impressions” mediation metrics

As we continue to improve Ad Manager Reporting, we’ve increased the accuracy of some mediation metric counting methodologies. Due to increased precision, you may notice a decrease in “Total code served count” and “Mediation fill rate” and an increase in “Unfilled impressions” when compared to the previous methodologies.


Coming soon

  • Updates to Demand Channel reporting dimension
    Beginning in January 2020, the Demand Channel reporting dimension will be updated. Exchange Bidding will be renamed Open Bidding, both retroactively and moving forward for consistency within the product. Additionally, for publishers involved in the beta for Network Bidding, this reporting dimension will also be renamed Open Bidding. If this causes changes to your reporting process, we encourage you to plan accordingly before this change occurs next year.
