Google announced a new feature within the AdSense console to help you compare your performance against other Google AdSense publishers, named the AdSense Score Card.
The AdSense score card will give you provide a summary of how well your ad settings, webpages and content are performing relative to other AdSense publishers. It is broken down into three categories right now, revenue optimization, site health and of course, Google+.
Here is a picture of one of my score cards:
I wonder how much weight real publishers put on this score card? Most the folks in the forums don't feel that it offers all that much of a help to them.
