On its official blog this week Google announced it was to start supporting “authorship markup — a way to connect authors with their content on the web”. According to the post this will enable websites to publicly link within their site from content to author pages.
For example, if an author at the New York Times has written dozens of articles, using this markup, the webmaster can connect these articles with a New York Times author page. An author page describes and identifies the author, and can include things like the author’s bio, photo, articles and other links.
According to Google it has worked with sites including the New York Times, the Washington Post, CNET and the New Yorker, prior to the launch of the markup to help get them set up. The markup will also been added to everything hosted by YouTube and Blogger, Google added.
For a more detailed description of how authorship works see the neat description below by the Search Engine Journal:
Sites that have large portions of content written by a specific author can denote the author of each piece of content and can specify the author’s page on the site. The author page can then include markup that specifies what select data on the page is. Google can then display portions of the specified data from the search engine results page, giving direct links to the author’s page, other content from the same writer, and other pages that belong to the same author (such as social sites).
