How to add rel="author" attribute to Drupal 7? In the brave new world of Google, great integration with Google+ is mandatory for all webmasters who want to get as much traffic as possible. If adding the rel="publisher" attribute to a website is done with the Meta Tags module, it seems that there's no official way for supporting the rel="author" attribute. For those of you who don't know about I am talking about, read this article from Google: Author information in search results 

Apparently support will be included in Drupal 8. I've seen some discussions about adding this to the Drupal 8 core. 

But how to implement this in Drupal 7?

I am asking this as a noob in customizing the insides of Drupal. So, if you have some good ideas, please keep this in mind.

Appreciate your ideas.
The rel=author property is now supported by the Drupal 7 Metatags module dev version.

After installing the metatags module (http://drupal.org/project/metatag), go to admin/config/search/metatags, and edit the front-page or one of the node pages. Under 'Advanced' you will see the author and publisher fields where you can input your google+ page URL. On the following screenshot, I've marked the places you need to change the configuration in pink.
