What is mediation in Admob?

Hello guys!

Can someone please explain me what is Mediation in the Admob? Are this mean I can use third-party networks with Admob code in application?

I want to try Chartboost and StartApp, but this networks isn`t listed there?

First read the documentation: https://support.google.com/admob/answer/3063564?hl=en

If you want to use third party networks that are not supported take a look at “custom events”: https://support.google.com/admob/answer/3083407?hl=en&ref_topic=3063091

TLDR: You must create a class for showing ads of your third party network and register this class in admob mediation.

Ad Mediation is a new technology that connects your app’s ad inventory to multiple ad networks. So you can serve ads from highest paying ad networks, ensuring that your fill rate is always high because you will have a larger, diversified inventory of ads. I’m not sure about Admob’s mediation specifically though. I’m not sure you can choose which ad networks’ adds you can serve.
