Google Authorship is one of the best things about Google+ accounts. Simply put, Authorship (and related tags) lets you associate your Google+ account with by lined content you have published on your own site (and potentially others). If your name is listed as the author of the content, you can associate it.
Google Authorship means the author of the specific content should be reliable so that the content can rank higher in the search engine. Some ways you can do are open up a Google plus account for your blogger market it very well and also include the Google plus account on your source slating he is the author of this content. I hope it helps
