AdPushup is an AdSense revenue optimization tool which can help publishers & bloggers make more money from their existing website traffic.
It uses advanced A/B testing to improve Adsense RPM (eCPM). It works by testing between different ad placements (locations), ad sizes, text vs image ads and ad themes.
The product is in beta mode at the moment and hence the usage is free.
