Google’s +1 project has been teased and talked about for quite some time now, and we finally get to take an in-depth look at what the +1 button is all about.
According to Google, “the +1 button is shorthand for ‘this is pretty cool’ or ‘you should check this out.’” If you’re signed into your Google account when searching from your desktop, you’ll notice a shiny +1 button next to search results. If you click that, Google will then let your friends know when sites you’ve +1′ed. Of course the same applies when you search, with Google letting you know what sites your friends have +1′ed as well.
Quick example: let’s say you were searching for chocolate chip cookie recipes, found a good one, and hit +1. A couple weeks later, a friend is looking for chocolate chip cookie recipes and they see a little pop-up that says you +1′ed that link, so they check it out. It couldn’t get any simpler.
For now, Google’s +1 button will only appear on search results through Google.com. Eventually, the button will makes its way onto websites as well, making it easier to +1 anything you see.
