People like knowing what their friends "like" online, so it's good business to help them find out. For businesses on Google+, this means helping users see their friends' +1 recommendations by linking +1's for your site with +1's on your Google+ page and ads. (If you're not familiar with Google Plus, +1 buttons are essentially Google's version of Facebook's Likes: shout outs from people in your social circles that tell you if they endorse the online content you're viewing at the moment.) Google explains how to add a small bit of code to your website to enable this feature, and how your advertisers can enable social extensions in AdWords. When you link your Google+ page to ads, Google can show more customer endorsements for your business, and that should boost your buzz factor.
