Authorship Stats in Google Webmaster Tools
Well, it’s been a while Google started to show author statistics in Google Webmaster Tools. This new feature shows the search statistics for the pages for which you are the verified author and shows up only when you have verified your authorship.

The stats that Google provides for verified authors are quite good actually and very detailed. It tells you how many pages Google indexed you as the verified author, how many impressions those pages got in organic search as well as how many clicks they received when showed up in organic search.
That was just the first row; the second row is a graph with daily details of impressions and clicks. The third row of data shows details of each page where you are the verified author. It shows how many impressions a page got over the selected period of time, how many clicks that page got, CTR and the average position in serp along with the percentage of changes in all those metrics.

The only catch is, you must use the same account for both Google Profile (Google Plus) and Google Webmaster Tools, otherwise, the author stats will not be able to gather data unless you have somehow connected (yes, it’s possible to connect two Google accounts to share data) your accounts.
If you have already verified yourself as the author of the websites you have in your Google Webmaster Tools account, you can access the statistics under Labs > Author Stats. If not, go verify your authorship and test with rich snippet testing tool to see if that’s working.
