Just a few months ago we bid farewell to Google’s Authorship Images from the search results, and with the new month of September we now bid adieu to Google displaying any Authorship data within their search results. Google’s authorship support page, says simply, “Authorship markup is no longer supported in Web search,” and encourages webmasters to look into rich snippets to improve their search results.
According to Mueller, Google tests showed removing authorship did not generally appear to reduce site traffic or increase ad clicks.
Mueller says Google is “strongly committed” to expanding support of structured markup such as schema.org and he says Google will continue to use it to show rich snippets in search results.
“We make these kinds of changes to improve our users’ experience”
He thanks webmasters for their efforts to improve their sites and says Google Search users will continue to see Google+ posts from friends and pages when relevant within the main results and on the right-hand side.
