Can I use an ad source as an Open Bidding and a waterfall ad source?
Yes. You can use an ad source as both an Open Bidding and waterfall ad source in the same mediation group. In fact, we always recommend having an ad source in both the waterfall and Open Bidding if possible. The ad source is called in an Open 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? (Beta)
You can now send bid requests to Open Bidding ad sources that serve in Russia and China. This feature is in beta.
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 Open Bidding ad sources?
Yes. To remove an Open 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 Open Bidding ad source you want to remove.
- Click Change status.
- Select Remove.
- Click Save.
To end your partnership with an Open Bidding ad source, you’ll need to work directly with the ad source.
How will I receive revenue from Open Bidding ad sources?
Revenue from most Open Bidding ad sources will be paid through AdMob. Some ad sources will pay the Open 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 Open Bidding increase latency?
How can I gauge the performance of Open Bidding?
How does Open Bidding work with network deals?
Networks that can participate in Open Bidding
The network with whom you have a deal can participate in Open 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 Open 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 Open Bidding
The winning bid from an Open 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.
