You’ll need to have your Google+ Business Page set up.
STEP 1- If you haven’t done it already, link to your website from your Google+ Business Page. Click “Edit Profile” and enter your URL in the website field.
STEP 2 - Add a link to your Google+ Business Page from your webpage. You have two options:
Option A: Add this code into the <head> section of your site – if you don’t have access, ask your website provider to add it for you. The link should look like this:
<link rel=”publisher” href=”[page_url]“>
You need to replace [page_url] with your Google+ profile URL, so the link would look like this:
<link rel=”publisher” href=”https://plus.google.com/111656652141598163752″>
Option B (our preferred method): You should have a link to your Google+ Business Page on your home page already; if you don’t, then add one. Add this code to the Google+ link:
Your Google+ business page link should now look like this (obviously, with your Google+ URL instead of ours):
<a href=”https://plus.google.com/111656652141598163752″ rel=”publisher”>
