Google Ads recently announced that on October 31, 2023, Google Ads intends to move primarily to real-time bidding auctions and will no longer respond to multiple calls in mediation. Before this date, Google Ads may begin to transition away from waterfall buying for some multi-call requests.
What this means for you as a publisher
Before this date, you should consider using a real-time bidding solution to access Google Ads demand. Through AdMob, you can access the following options for real-time bidding:
- Use AdMob Network in bidding with AdMob mediation. AdMob Network includes demand from Google (Google Ads, Display & Video 360) and third-party ad sources.
- Use partner bidding with a supported third-party mediation platform to enable Google (Google Ads, Display & Video 360) to bid on your inventory in real-time bidding auctions - even if you do not use AdMob as your mediation platform.
If you are calling Google Ads in bidding, there is no action for you to take. Other third-party demand sources may have their own bidding behavior. Here's how to get started with real-time bidding.
Use AdMob Network in bidding with AdMob mediation
When you use AdMob mediation, the AdMob Network is automatically added as a bidding source. This means that the AdMob Network bids on your ad requests in real-time.
This allows your ad sources to compete equally in a single, unified auction. For any given impression, the bidding ad source that serves the ad is the highest paying advertiser.

Use partner bidding to access Google demand on third-party mediation platforms
Partner bidding enables you to access Google demand as a bidding source on supported third-party mediation platforms. Google (Google Ads, Display & Video 360) can bid on your inventory in third-party real-time bidding auctions - even if you do not use AdMob as your mediation platform.
First, you’ll set up a partner bidding ad unit in AdMob. Then, you can set Google as a bidding source and map your ad unit in your third-party mediation platform (not AdMob).

Until further notice, we believe Google Ads will respond to a single call in waterfall mediation after October 31, 2023. However, to maximize revenue, we recommend that you access Google Ads demand via a real-time bidding solution, such as AdMob Network in bidding with AdMob mediation. We will continue to monitor any updates from Google Ads and proactively update this page with any important changes. |

Google Ads shares more information on their shift to real-time bidding. For a temporary period of time, Google Ads will still respond to multiple calls within hybrid waterfalls on supported partner platforms, as well as AdMob and Ad Manager. Hybrid waterfalls should be set up by adding a bidding ad unit to your existing waterfall mediations. Google Ads will begin to reduce spending on multicall requests in waterfalls that do not contain a bidding ad unit. On October 31, Google Ads will stop buying on multicall waterfall requests that do not contain a bidding ad unit. Google Ads may still buy on mediation waterfalls that only make a single call to Google Ads demand. |

It is our goal to complete this transition as early as January 2024.” |
