Mediation Overview

Mediation is the core feature of TopOn that helps publishers manage all of the ad sources to serve ads to their apps in one placement. 

By using mediation, publishers can send incoming ad requests to multiple ad sources and help ensure them find the best available ad sources to fill those requests. So to improve the filled rate as well as maximize the total performance.
