The first step in adding the Google Authorship Tag is adding it to your site.
If you have a blog, like I have here the first thing to do is add this tag to your author page or blog:
<a “url fn author” rel=“me” href=https://plus.google.com/112480022787124899502/about >
*Note Make sure you have a headshot of yourself.
This will connect to your Google+ About Page as seen below. Follow next step below screen shots.
Head on over to Google's Rich Snippet page to verify the tag is working. Type in your blog, post or article and check the results to see if it is verified.
There is another way to easily add your Authorship is to have a verifiable e-mail address of the domain that your blog and articles are on and head on over to the Google Authorship page on Google+ and submit your e-mail address and verify it.
Add this Byline to your blog or About page.
