Add an Open Bidding ad source (Closed Beta)

After you've created a mediation group, you’ll need to add third-party ad sources to fill the ad requests it will receive. 

Learn more about the ad sources available for Open Bidding and their requirements in the Google Developers guide for Android and iOS. 

Complete the steps below to add an Open Bidding ad source to a mediation group.

Note: You must have a partnership with the Open Bidding ad source before it can accept ad requests from your AdMob account. In many cases, this is as simple as creating an account on the ad source's home page. 

1. Sign in to your AdMob account at https://apps.admob.com.
2. Click Mediation in the sidebar.
3. Click the name of the mediation group to which you're adding the ad source. 
4. Click Add ad source in the Open Bidding ad sources table.
5. Find the ad source in the list that appears or begin typing the name of the ad source in the search box. Click Select next to the ad source you want to add. 
6. Review and check the Accept terms checkbox to accept the terms of using Open Bidding and authorize AdMob and Google to access your account. If you've previously authorized this ad source, you won't be asked again.
7. Click Continue.
8. Map your ad units by entering the mapping details for each ad unit. In most cases, these details will be available in your account with the ad source.
9. Click Done.
10. Click Save. The mediation group will be saved.

Using the AdMob Network as an Open Bidding ad source

To use Open Bidding, the AdMob Network must be one of your Open Bidding ad sources. When you create a new mediation group, the AdMob Network is automatically added as an Open Bidding ad source. 

When you add a third-party Open Bidding ad source to an existing mediation group, the AdMob Network is automatically converted from a waterfall ad source to an Open Bidding ad source.

Converting the AdMob Network to a waterfall ad source

To convert the AdMob Network to a waterfall ad source, click  and select Move to waterfall ad sources.

To convert the AdMob Network to a waterfall ad source, you must first remove all other Open Bidding ad sources from the group.

To convert the AdMob Network back to an Open Bidding ad source, click  and select Move to Open Bidding ad sources. You can also click  on the eCPM column and click the Real-time eCPM (Open Bidding) toggle.
