I was first using authorship tag on all the pages of my website. That gave me a pretty decent improvement in the click through rate. However, I have recently added ratings on my website, i.e. all my pages are being rated by the readers and the same has been made available to Google via microdata.
The result being that the image of the author from the Google search results has been removed. It now shows ratings given by the customers and just writes the name of the author.
What will be its impact on the click-through rate? Is it OK to have the ratings or should I switch back to only authorship tag as I was using in the past?
