After three years the great Google Authorship experiment has come to an end … at least for now.

Today John Mueller of Google Webmaster Tools announced in a Google+ postthat Google will stop showing authorship results in Google Search, and will no longer be tracking data from content using rel=author markup.

This in-depth article, which I’ve jointly co-written with Mark Traphagen, will cover the announcement of the end of Authorship, the history of Authorship, a study conducted by Stone Temple Consulting that confirms one of the stated reasons for cessation of the program, and some thoughts about the future of author authority in search.

I can't say I ever used the rel=author tag. Whoops. 

A whopping 70% of authors made no attempt to connect their authorship with the content they were publishing on major web sites. Of course, this has much to do with how Google attempts to promote these types of initiatives. In short, they don’t. They rely on the organic spread of information throughout the Interweb ecosystem, which is uneven at best.
