I want to link my website to Google+.
(By adding a short line of code, 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.) Example of the code I need to add - Google+
Where do I add the code? When I go to the Appearance -> Editor, what template should I insert the code on & where within the code?
Thanks in advance for your help!
