Try push-notifications to better monetize your Android app(s) at Airpush. Airpush is a 'push-notification' ad network that serves ads in the push-notification trays of Android devices. This ad unit generates much higher CTR's and our developers are experiencing $3+ CPM's because of this. This ad unit can also monetize both active and inactive users increasing your fill rate drastically. Compare this to the typical CPM's from more traditional ad networks ranging in the $.20-$.30 range and it may be worth to test us out! Feedback welcomed!
