Google Authorship: Move rel=”author” on your head

In earlier post, I told you the way to make your avatar (your real photo as author’s image) appear beside the Google search results, it’s calling Google Authorship.
As you know, one of important steps is verify your website by add the rel="author" with link to Google+ profile from your webpage like this:

<a href="[profile_url]?rel=author">Google</a>

Since June 2012, Google is now allowing rel="author" markup through a <link> element in the head of your site. This makes adding rel="author" to your site properly a lot easier.
So the element on your webpage should look like this:

<link rel="author" href="[profile_url]/posts"/>

Replace [profile_url] with the your Google+ profile URL, like this:

<link rel="author" href=""/>

Once you’ve done the above, use the rich snippet testing tool to confirm it works.
