Google has introduced the publisher scorecard to help you understand how your site is performing relative to the sites of other AdSense publishers,close on the heels of completing its 10 years. Google Adsense scorecard provides you with a summary of how well your ad settings, webpages and content are performing relative to other AdSense publishers.
This publisher scorecard is organized into different categories, such as revenue optimization and site health, and each category is scored on a scale of one to five blue dots indicating your performance. A Google Adsense publisher will also be able to see updates to your score as you make improvements.
More interestingly, Google will not take any action on low scores, since this scorecard is just an informational tool only to give you greater insights into how your site is performing.
