How to add the Google +1 button to your website
Google started rolling the +1 button as an experimental version of Google Search. Today, the +1 button is available to everyone and this means that “you” as a webmaster can add the +1 button to your website and let people share on Google your content.
Google made the process really simple as it is with Facebook and Twitter. Just grab the code, copy/paste and you’re set.
