@gamesura Ad Mediation helps when a Admob can not provide Ads in particular region.. for example, majority of my users(almast 90%) are from Asian countries and inspite of 3000+ impression, the revenue for ll the is very low. I assume the Ad quality for those regions are utterly low.
So I wanted to add mediation where I can combine multiple Ad networks in AdMob, AdMob will return automatically decide higher valued Ad and show it to the user.
@szymek yes I am using Interstitial Ads, and inspite of that the revenue is low
How often does your friend show the Ads? I only show teh Interstitial Ads if the player dies or wants to go to Main menu (every 60 secs). I dont show Ads while the game is going on.
