Below are answers to some of the most frequently asked questions about bidding.
How can I set up a partnership with a bidding ad source?
What third-party ad sources support bidding?
Do I have to create a new mediation group to use bidding?
What version of the SDK should I use?
What happens to my existing ad networks if I use bidding?
Can I use an ad source as a bidding and a waterfall ad source?
Yes. You can use an ad source as both a bidding and waterfall ad source in the same mediation group. In fact, we always recommend having an ad source in both the waterfall and bidding if possible. The ad source is called in a bidding auction first. If the ad source places a bid, then it isn’t placed in the mediation waterfall a second time because the bid represents what they’re willing to pay.
However, if the ad source doesn’t place a bid, then it is still called as a waterfall ad source in the mediation waterfall. This gives the ad source a second chance to serve an ad.
Can I serve ad requests in Russia and China?
You can now send bid requests to bidding ad sources that serve in Russia and China.
Creatives will be reviewed with strict, country-specific policies, and blank creatives will not be allowed to serve.
This beta does not currently support ad sources using a custom mobile SDK. Ad sources must be using the Google Mobile Ads SDK.
Can I remove bidding ad sources?
Yes. To remove a bidding ad source from a mediation group:
- Click the name of the mediation group where you want to remove the ad source.
- Click the checkbox next to the bidding ad source you want to remove.
- Click Change status.
- Select Remove.
- Click Save.
To end your partnership with a bidding ad source, you’ll need to work directly with the ad source.
How will I receive revenue from bidding ad sources?
Revenue from most bidding ad sources will be paid through AdMob. Some ad sources will pay the bidding revenue to you directly. These ad sources are called direct pay.
When you add a direct pay ad source in AdMob, you’ll be asked to acknowledge that the ad source will pay you directly. Check your agreement with the direct pay ad source for more details.
Will bidding increase latency?
How can I gauge the performance of bidding?
How does bidding work with network deals?
Networks that can participate in bidding
The network with whom you have a deal can participate in bidding auctions alongside other ad sources. The highest bid will be placed in the mediation waterfall based on its eCPM value, whether or not it’s the network with whom you have a deal.
If the network doesn’t place a bid in the bidding auction, it can still be called in the mediation waterfall. If the network places a bid and doesn’t win, it will not be called again in the mediation waterfall.
Networks that don’t participate in bidding
The winning bid from a bidding auction is placed in the waterfall according to its eCPM value. If your network deal has a higher eCPM than the winning bid, it will be called first. If the network doesn't have an ad to serve, the ad source with the winning bid will serve the ad.

What do I do when ad sources do not appear to be bidding on my app’s ad requests?
When you see that an ad source is not responding with bids for your inventory, this is a possible indicator of many different issues with serving. It could be that the request lacks the signals acquired via the most current version of the ad source’s client SDK (which must be installed on your app). It can also be that you haven’t installed the latest version of the GMA SDK. Or, it could be due to other reasons that are ad source and configuration specific.
Check that you are using the latest versions of the ad source’s SDK and the GMA SDK. The Mediation Test Suite can help verify this. An ad source may not bid due to its setup and decisioning, so Google support often does not have insight and may not be able to help troubleshoot these issues.
If you perceive an issue with a particular ad source, log into your account with that ad source to check for configuration errors and to read troubleshooting documentation.

When using ad inspector, you may encounter the following issues when testing your bidding ad sources:
- No SDK signal found: Some ad sources may need an SDK and adapter installed and configured correctly to use bidding. Learn more about the SDK requirements for Android and iOS.
- No user consent provided: The ad source may not be eligible for a bid request if the user has not provided the necessary consent. This may be expected behavior. Learn more about implementing consent tools, such as GDPR, in the AdMob policies and restrictions.
- No ad returned: The ad sources may have decided to not bid for the ad request or they may not be eligible to bid for it. There are several possible reasons for this issue. Here are some examples:
- The ad source may only bid under certain conditions, such as specific geographic areas.
- The ad source may not have an ad for the bid request.
- There was an unexpected system error or timeout on the ad source’s end.
