I know adsense works, they have good solid stats, they pay up, its well known, the ads get clicked, fact. MobileCore, is for app advertising. They sell it using big eCPM pitch, and fancy interstitial ads. Im pretty sure their stats are no match for adsense, but its all about revenue. Maybe im being a bit mislead by the "high ecpm" or looking at it all wrong. Its about the clicks right? The eCPM is calculated AFTER the ads performance? So whats other peoples view on this
