(Google Authorship Project)
If you understand SEO, you should also know about Page Rank (a metric defined by Google to analyse and identify the value of a website or webpage using link graph). Similar to Page Rank, Google has introduced a new metric called Author Rank, which Google uses to identify the authority of a blogger or web author. (Ref Google Patent on Author Rank). Google will not replace page rank with author rank, but it will use both these metrics to improve relevancy of results and promote posts of author’s with greater influence.
