Today John Mueller of Google Webmaster Tools announced in a Google+ post that Google will stop showing authorship results in Google Search results, and it will also no longer be tracking data from content using rel=author markup.
This means articles will no longer include a link to the Google+ profile of their author. The company says that it found the information isn’t as useful to its users as it hoped, and in some cases even distracts from the overall search results.
Mueller added If you’re curious — in our tests, removing authorship generally does not seem to reduce traffic to sites. Nor does it increase clicks on ads. We make these kinds of changes to improve our users’ experience.
From our point of view: this is a lie, autorship undoubtedly distract from ads! while ads are displayed as text, autorship display an image, which naturally attract the human attention more than a text, or at least distract from the ads!
