Authorship was first introduced three years ago, however the system that linked your Google Plus account with any content that you published on Google was scrapped on August 28th when Webmaster John Mueller announced authorships ending. With authorship your profile picture and often your Google Plus data was displayed alongside the content that you published online.
Even though Google did not exclusively reveal that your search engine listings were affected by whether you used authorship or not, many were under the impression that it did and therefore many marketers began using it straight away. Despite this belief, it seems that Google’s scrapping of the authorship feature, perhaps reinforces that it really did have little influence over your search engine listings. Instead nowadays it seems that Google search engine listings are affected by other traditional methods of “doing SEO” such as meta tags, title tags, URL’s keyword optimised content and so on.
