Today we’re taking that a step further, enabling you to share recommendations with the world right in Google’s search results. It’s called +1—the digital shorthand for “this is pretty cool.” To recommend something, all you have to do is click +1 on a webpage or ad you find useful. These +1’s will then start appearing in Google’s search results.
The +1 button will appear next to each search result
After pressing the +1 button, you have the option to undo the action immediately
Say, for example, you’re planning a winter trip to Tahoe, Calif. When you do a search, you may now see a +1 from your slalom-skiing aunt next to the result for a lodge in the area. Or if you’re looking for a new pasta recipe, we’ll show you +1’s from your culinary genius college roommate. And even if none of your friends are baristas or caffeine addicts, we may still show you how many people across the web have +1’d your local coffee shop.
The beauty of +1’s is their relevance—you get the right recommendations (because they come from people who matter to you), at the right time (when you are actually looking for information about that topic) and in the right format (your search results). For more information about +1, watch this video:
So how do we know which +1’s to show you? Like social search, we use many signals to identify the most useful recommendations, including things like the people you are already connected to through Google (your chat buddies and contacts, for example). Soon we may also incorporate other signals, such as your connections on sites like Twitter, to ensure your recommendations are as relevant as possible. If you want to know who you're connected to, and how, visit the “Social Circle and Content” section of the Google Dashboard.
To get started +1’ing the stuff you like, you’ll need to create a Google profile—or if you already have one, upgrade it. You can use your profile to see all of your +1’s in one place, and delete those you no longer want to recommend. To see +1’s in your Google search results you’ll need to be logged into your Google Account.
We’ll be slowly rolling out +1’s, starting in English on Google.com. If you can’t wait to start seeing +1’s, we’ll soon let you opt-in to the launch by visiting our experimental search site. Initially, +1’s will appear alongside search results and ads, but in the weeks ahead they’ll appear in many more places (including other Google products and sites across the web). If you’re an advertiser and want to learn more about how the +1 button works on search ads and websites, visit our AdWords blog.
We’re confident that +1, combined with all of the social content we’re now including in search, will mean even better, more relevant results than you get today.
