+1 helps people discover relevant content—a website, a Google search result, or an ad—from the people they already know and trust. The +1 button appears on Google search, on websites, and on ads. For example, you might see a +1 button for a Google search result, Google ad, or next to an article you're reading on your favorite news site.

Adding the +1 button to pages on your own site lets users recommend your content, knowing that their friends and contacts will see their recommendation when it’s most relevant—in the context of Google search results. In addition, a user's +1's appear on the +1 tab of their Google Profile. While +1’s are always public, users can choose to make the +1 tab visible or invisible on their profile.

When a signed-in Google user is searching, your Google search result snippet may be annotated with the names of the user's connections who've +1'd your page. If none of a user's connections has +1'd your page, your snippet may display the aggregate number of +1's your page has received.
