Step 1:
Create a Google+ Profile link to your website.
Example:
<a href="https://plus.google.com/101094135981"777692560? rel=author">Plus1Followers</a>
The important thing you must note here is include ?rel=author parameter If you missed this parameter, Google won’t be able to associate your content with your Google+ profile.
Step 2:
Add a reciprocal link back from your profile to the site(s) you just updated.
2.1: Edit the Contributor To section.
2.2: Enter your website link in the text box.
2.3: If you want, click the drop-down list to specify who can see the link. Make sure it is in Public
2.4: Click Save.
