Follow these simple steps and you can start taking advantage of Google Authorship today:
Go to Google+ and select "Profile" from the drop down side menu. While there change your profile photo to one with a head and shoulders shot.
Example here: Michael Mason.
Using The "Author" Tag
You should have a tag somewhere on each article. Something like "By:" or even better "Written By:" and then your name.
The name in your byline should match your Google+ name exactly. For example, if your name has a hyphen in it then your byline and Google+ name should be identical. "Written By: John Smith-Jones" on your website should link to a Google+ page with the name "John Smith-Jones".
I use the following mark-up:
<a title="Written By Michael Mason" href="https://plus.google.com/102424903613296257827" target="_blank" rel="author">Michael Mason</a>".
Simply sign in to Google+ and then visit https://plus.google.com/authorship. Add your mail address to the form and click the verify button in the mail you receive.
Of course, there's much more to Google Authorship than simply placing a link back to your Google+ profile but it's a start and I hope you start reaping the rewards also.
