This plugin allows WordPress-driven websites with multiple authors to properly claim authorship, linking each individual writer to their associated Go
In order to get the little photograph of the author beside articles in the search results, you need to “claim” yourself as the writer of the article by linking to your Google+ profile.
You can hardcode this for a single author website, but requires more complex hacking for a multiple author website, where each writer should get the credit for the articles they wrote, and lend their personal authority to help boost the pages in the search results.
This plugin adds a new Google+ field to every user profile in the WordPress database. Your authors can copy-paste their profile link into that field.
The plugin then automatically links back to the profile on every article they write, as defined by Google’s instructions.
You have to wait for the new pages to get indexed before the authorship photos appear beside your articles, but you can test your pages beforehand using the Rich Snippets tool.
