+1 annotations help users know when your organic search results and ads are relevant to them, increasing the chances that they'll end up on your site.
As results become more personal and relevant, we believe that users are not only more likely to click, but they're more likely to act as well. +1 annotations bring you pre-qualified users, who just received recommendations from their friends and are actively looking for your content.
