Google +1 button - If you think something is cool, +1

Google expanded its social offerings with a new +1 feature. +1 is a feature that lets you recommend certain Web sites with the click of a button, much like you might click on like on Facebook.

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.

To get started, all you need is to setup 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 think something is cool, +1.
