Editor’s note (8/28/14): Google has completely dropped all authorship functionality from the search results and webmaster tools. Other than the authorship markup code that’s now worthless, what changes should you make to rank well in Google?
As this article from April 13, 2013 sets forth, nothing at all. The message is aimed at the mythical Author Rank, which was supposed to be the outcome of Authorship, but the point is that what would have worked under Authorship is what already works. Enjoy.
It was a smashing success, which indicates that writers and other online content creators are excited about these topics. And you should be.
But let’s be clear – as best as anyone can tell, Author Rank has not been implemented yet. And that means there’s some chance it may never become an algorithmic aspect of the way Google ranks web pages.
