Google let me in to the beta of the new Adsense interface. It is pretty cool. Unlike the Adwords "improvements" which I still don’t like. The new Adsense does a lot of useful things, The CTR to eCPM tool is interesting, and the daily trends let me know if it was my traffic, or my advertiser that was sucking on a given day.
And while I can’t change if my ads are CPM or CPC, it is interesting to know that I am often getting a higher eCPM from CPM ads than CPC.
Overall I have to say I like the extra information, and since the menus haven’t changed much I like it.
