I’ll be honest, I really thought virtually all Google AdSense publishers were part of the new AdSense interface, known as V3. They have been beta testing it for over a year now and I personally have been using it for a year or so now.

A year of beta testing a beta? Yea, Google is known for keeping things in beta – but they do deliver the beta to everyone sooner than a year. Meaning, they may be known for keeping the beta label on products, but it doesn’t typically shy them away from releasing the beta to more and more people. A year long beta push, to me, seems long.

In any event, there are tons of threads from Google AdSense publishers on the AdSense beta console. Like I said, I have screen shots from a year ago, and yea – they have slightly changed. Some threads are at Google Blogoscoped Forums, Google AdSense Help, and WebmasterWorld.

The main questions I have seen are what is the “coverage” metric and the “RPM” metric. A thread specifically about the coverage metric has Googler Guillaume explaining that:

RPM is calculated by adding up the price charged to advertisers (CPM) for each ad block on the webpage, then subtracting the cost of delivering that advertising.
