Google is introducing a new benchmarking tool for AdSense accounts called Publisher Scorecards.
Located on the Home tab in your AdSense account, the scorecard offers a performance summary of your ad settings, webpages and content relative to other AdSense publishers.
Each performance category — revenue optimization, site health, and, notably, Google+ — are scored on a scale of one to five blue dots.
A red or yellow exclamation indicates issues that should be fixed. The scorecard is updated to reflect any improvements you make. Google reiterated that it will not take any action on low scores, stating “this in an informational tool only to give you greater insights into how your site is performing.”
