Link EasyBlog Site to Google+ Page

I am trying to link my EasyBlog site to a Google+ Page in order to have it show up in Google Search Results. I received these instructions from Google:

"you can make your Google+ page eligible to show up on the right hand side of the Google search page for relevant queries and make your Google+ page more discoverable."

"Ask your site's webmaster to add the following line of code to your site's homepage:
<a href="https://plus.google.com/115318507276690674229" rel="publisher">Google+</a>

My question is simply, where in EasyBlog would I put this line of code? Do you have a recommendation?
Can it be done through the Administrator's interface, or do I need to directly edit one of EasyBlog or Joomla's files directly?

Thanks in advance,
