Google continues to expand the usage of authorship markup offered to web publishers.
They have added support for this markup in the Google Webmaster Tools.
Users can now check their own stats for a domain from this platform.
Authors have also been giving us a lot of feedback on what else they’d like to see, so today we’re introducing “Author Stats” in Webmaster Tools that shows you how often your content is showing up on the Google search results page. If you associate your content with your Google Profile either via e-mail verification or a simple link, you can visit Webmaster Tools to see how many impressions and clicks your content got on the Google search results page.
