Benefits of Google +1′s
Once you have selected the code, you then have the option to put the +1 Button wherever you like on your site. You are the most familiar with your pages and the messages you are trying to convey to your readers and customers, so go with your gut on where you think the most effective placement can be. Google offers the recommendations of putting the button near the title, near sharing links and above the fold of a page. You can choose to use multiple +1 Buttons on each page, so feel free to put them at the beginning and end of item descriptions or stories to draw the most positive feedback possible.
