In June 2011, Google introduced author information in the SERPs. Since doing so, much has been written about the importance of ensuring search marketers have taken steps to set up authorship in Google+.
Intuitively, it makes sense that greater attention is drawn to search results with pictures on them and several studies confirm higher click-through rates (CTRs) for search results with authorship images.
In addition to CTRs being higher for search results with vs. without authorship markup, many have theorized that Google will start using an author’s influence in determining how to rank content created by them for relevant queries. This makes it even more critical that publishers set up authorship, linking their online content to their Google+ account.
