New “Opt-in” Adsense design focuses on easily allowing you to save and view reports to bring up for easy comparison. A saved report is added to the left menu. Applying filters such as CPC, and CPM performance is a snap.
The new performance report dashboard has a nice feel to it. (no picture). It also seems like a more device friendly layout. (I have yet to test it with a tablet or mobile)
To opt-in just log in to your Adsense account and click the opt-in link.
You’ll notice an “opt out” button in the lower left, in case you just aren’t ready for the changes yet.
