Step 1: We need Google+ profile for the author which we are going to use it in the blog section.
Step 2: Create author page like the below link and provide the Author’s Google+ profile in the author page and implement rel=”me” tag in that.
Sample URL: http://www.pandiyarajan.com/blog/author/pandiyarajan/
Step 3: We need to provide the rel=”author” attribute in each of the author’s blog post. For example, when you consider the following post http://www.pandiyarajan.com/blog/how-to-audit-existing-google-adwords-campaign/ the rel=”author” is implemented like the below code.
Posted by<a rel=”author” href=”http://www.pandiyarajan.com/blog/author/pandiyarajan/”>Pandiyarajan</a>
Step 4:After login to your Google+ profile, please follow the link https://plus.google.com/me/about/edit/co which will take you to the contributor section in the Google+ profile. You should add the website url like the below screenshot.
