When we introduced the +1 button in March, Google search took a small step in an important direction. Search results can be more helpful, and more personal, when recommendations from the people you trust are there to guide your way.

The +1 button can help publishers, too. As potential visitors see recommendations from their friends and contacts beneath your Google search results, you could see more, and better qualified, traffic coming from Google.

Since we announced +1, we’ve gotten lots of requests from Google search users and webmasters alike for +1 buttons in more places than just search results. That’s why today we’re making the +1 button available to sites across the web. Sometimes you want to recommend a web page after you’ve visited it. After all, how do you know you want to suggest that great article on Spanish tapas if you haven’t read it yet?

We’ve partnered with a few sites where you’ll see +1 buttons over the coming days:

You'll also start to see +1 buttons on other Google properties such as Android Market, Blogger, Product Search and YouTube.

Adding +1 buttons to your pages is a great way to help your content stand out in Google search. By giving your visitors more chances to +1 your pages, your search results and search ads could show up with +1 annotations more often, helping users see when your pages are most likely to be useful.

To get started, visit the +1 button tool on Google Webmaster Central. You’ll be able to configure a small snippet of JavaScript and add it to the pages where you want +1 buttons to appear. You can pick from a few different button sizes and styles, so choose the +1 button that best matches your site’s layout.

In the common case, a press of the button +1’s the URL of the page it’s on. We recommend some easy ways to ensure this maps as often as possible to the pages appearing in Google search results.

If your site primarily caters to users outside of the US and Canada, you can install the +1 button code now; the +1 button is already supported in 44 languages. However, keep in mind that +1 annotations currently only appear for English search results on Google.com. We’re working on releasing +1 to searchers worldwide in the future.

If you have users who love your content (and we bet you do), encourage them to spread the word! Add the +1 button to help your site stand out with a personal recommendation right at the moment of decision, on Google search.

To stay current on updates to the +1 button large and small, please subscribe to the Google Publisher Buttons Announce Group. For advanced tips and tricks, check our Google Code site. Finally, if you have any questions about using the +1 button on your websites, feel free to drop by the Webmaster Help Forum.

In 2009 we first introduced Social Search on google.com as an experimental feature designed to help you find more relevant information from your friends and the people you care about. Since then we’ve been making steady improvements to connect you with more people and more relevant web results. Today, we’re bringing Social Search to more users around the globe.

Just like on google.com, social search results in other languages and on other domains are mixed throughout the Google results page based on their relevance. For example, if you’re looking for information about low-light photography and your friend Marcin has written a blog post about it, that post may show up higher in your results with a clear annotation and picture of Marcin:

Social search results can rank anywhere on the page, and you’ll see who shared the result in the annotation underneath.

Social Search can help you find pages your friends have created, and it can also help you find links your contacts have shared on Twitter and other sites. If someone you’re connected to has publicly shared a link, we may show that link in your results with a clear annotation. So, if you’re looking for information about modern cooking and your colleague Adam shared a link about Modernist Cuisine, you’ll see an annotation and picture of Adam under the result. That way when you see Adam in the office, you’ll know he might be a good person to ask about his favorite modern cooking techniques.

Social Search includes links people share on Twitter and other services.

So how does this all work? Social search results are only visible to you and only appear when you choose to log in to your Google Account. If you’re signed in, Google makes a best guess about whose public content you may want to see in your results, including people from your Google chat buddy list, your Google Contacts, the people you're following in Google Reader and Buzz, and the networks you’ve linked from your Google profile or Google Account. For public networks like Twitter, Google finds your friends and sees who they’re publicly connected to as well. You can see a complete list of the people included in your social search results in your personal Google Dashboard (this display is private).

Social Search is rolling out globally in 19 languages and should be available in the coming week, with more languages on the way. People around the world will find similar types of social results as people in the U.S., and we plan to introduce the +1 feature as soon as we can. With these changes, we want to help you find the most relevant information from the people who matter to you. To learn more about Social Search, check out our help center.
