My iOS games has admob ads, and they are best. Was using chartboost too, but their ecpm was lower and I disabled them. Was using appodeal mediation, but I dont like them, as it looks like they faked stats or it was just errors, I dont know.
So now only admob.
FB is harder to integrate and their ecpm is similar or lower than admob, and sdk is very big, so never tried to use them.
Happy with admob so far![]()
My admob ecpm for last week is $6.16.I start using FB is easy to integrate. How much are you making per click?
