There are 2 ways to get authorship data connected to your personal Google+ page so as to get the author’s thumbnail photo next to content that Google displays in its search results:
(1) First method:
Verify the author’s email with Google (when matching the domain of the website) at https://plus.google.com/authorship and include a byline in each post or article (for practical reasons, the byline would only work for blog posts and articles on main website), NOT for content posted elsewhere on the web or for static content on the main site.
