Google+ Rich Snippet Tool
The Google+ platform released a tool that allows you to customize the snippet people see when your page is shared. Using this tool, you can generate code for your page that indicates the images and text that best represent what's being shared.
When used in conjunction with Google Authorship, you should gain a higher click-through rate in the SERP's as you post will be optimized with a good description, and a relevant image.
You have the choice of adding the code to the header or body source of your webpage.
