Finally there is an easy way how to implement Google Authorship in Joomla sites. I created plugin SD Google Authorship, for easy use and quick setup on Joomla site. Its simply working for multiple authors as well.
Plugin is compatible with Joomla 1.5, Joomla 2.5 and Joomla 3.x.
Since plugin version 3.2 it's properly supports K2 extension
There are only few steps you have need do to get authorship marking for Goole ready on your Joomla site.
- Download SD Google Authorship plugin and install it
- Allow "System - SD Google Authorship" plugin in Joomla Plug-in management
- Create contact for each author and associate it with user and set Website URL as your Google Plus profile
Thats all. If you want be sure, that all is working properly, get some URL with article and put it to Google rich snippet testing tool.
