Ad Network Mediation overview
What is AdMob Ad Network Mediation?
This product coordinates with ad networks to help maximize your fill rate and increase your monetization. We call it AdMob Mediation for short.

If your top choice can't fill the ad request, our product works down a list of alternatives and contacts them in the order you specify. It continues until it finds a network to fill the request or it’s tried all your chosen networks.
Your settings tell AdMob Mediation how to choose between these networks. You can allocate traffic based on eCPM (effective cost per thousand impressions—an estimate of ad revenue) and location.
For example, you may want AdMob Mediation to try a certain network first when ad requests come from a specific country.

For each ad request, AdMob Mediation tailors its network search to your priorities.
