Google+ Badge

Google+ badge is a social networking plugin to let people follow your Google+ pages or profiles. In other words, it is a kind of Facebook likebox that shows how many people likes your facebook page. I would recommend to embed both buttons into "about us" or home page of your site. More google+ followers will help increase more traffics to your site as well as page rank.
