Now that you’ve created a Google+ page for your own, company, product or blog, how do you get people to follow the page? Use these free Google+ Badges or Buttons (right click on the image, then click on Save As) and promote your presence on Google’s social network.
Connect your site with the Google+ page by adding this code -
<a href=”https://plus.google.com/<PAGE_ID>/”><img src=”<IMG URL>” alt=”" border=”0″ /></a>
(where PAGE_ID is the long number from the URL of your Google+ page).
Make it simple for users to connect with you.
