Introducing the +1 button

Monday, March 28, 2011

We all know what it’s like to get a bit of help when you’re looking for it. Online, that advice
can come from a number of places: a tweet, a shared video, or a blog post, to name a few. With
Google Social Search
we’ve been working to show that content when it’s useful, making search more personally relevant.

We think sharing on the web can be even better–that people might share more recommendations,
more often, if they knew their advice would be used to help their friends and contacts right when
they’re searching for relevant topics on Google. That’s why we’re introducing the
+1 button,
an easy way for Google users to recommend your content right from the search results pages (and,
soon, from your site).

+1 is a simple idea. Let’s use Brian as an example. When Brian signs in to his Google Account and
sees one of your pages in the organic search results on Google (or your
search ads
if you’re using AdWords), he can +1 it and recommend your page to the world.

The next time Brian’s friend Mary is signed in and searching on Google and your page appears, she
might see a personalized annotation letting her know that Brian +1’d it. So Brian’s +1 helps Mary
decide that your site is worth checking out.

We expect that these personalized annotations will help sites stand out by showing users which
search results are personally relevant to them. As a result, +1’s could increase both the quality
and quantity of traffic to the sites people care about.

But the +1 button isn’t just for search results. We’re working on a +1 button that you can put on
your pages too, making it easy for people to recommend your content on Google search without
leaving your site. If you want to be notified when the +1 button is available for your website,
you can sign up for email updates at our
+1 webmaster site.

Over the coming weeks, we’ll add +1 buttons to search results and ads on Google.com. We’ll also
start to look at +1’s as one of the many signals we use to determine a page’s relevance and
ranking, including social signals from other services. For +1’s, as with any new ranking signal,
we’ll be starting carefully and learning how those signals affect search quality over time. At
first the +1 button will appear for English searches only on Google.com, but we’re working to add
more languages in the future.

We’re excited about using +1’s to make search more personal, relevant and compelling. We hope
you’re excited too! If you have questions about the +1 button and how it affects search on
Google.com, you can check the
Google Webmaster Central Help Center.
