Google announced on its blog today that it has revamped its search engine to integrate real-time search results from users of Twitter, Facebook and MySpace.

“I would say that real time search is the natural evolution of universal search,” Marissa Mayer, Google’s vice president of search products and user experience, said at an event at the Computer History Museum in Mountain View, California.

Mayer said that Google was not currently selling keyword ads alongside real-time search results, and said the company was currently focused on perfecting the consumer experience with real-time search.

Here is the official announcement from Google’s blog:

“”””We’re introducing new features that bring your search results to life with a dynamic stream of real-time content from across the web. Now, immediately after conducting a search, you can see live updates from people on popular sites like Twitter and FriendFeed, as well as headlines from news and blog posts published just seconds before. When they are relevant, we’ll rank these latest results to show the freshest information right on the search results page.

Try searching for your favorite TV show, sporting event or the latest development on a recent government bill. Whether it’s an eyewitness tweet, a breaking news story or a fresh blog post, you can find it on Google right after it’s published on the web.

Our real-time search enables you to discover breaking news the moment it’s happening, even if it’s not the popular news of the day, and even if you didn’t know about it beforehand. For example, in the screen shot, the big story was about GM’s stabilizing car sales, which shows under “News results.” Nonetheless, thanks to our powerful real-time algorithms, the “Latest results” feature surfaces another important story breaking just seconds before: GM’s CEO stepped down.

“””Click on “Latest results” or select “Latest” from the search options menu to view a full page of live tweets, blogs, news and other web content scrolling right on Google. You can also filter your results to see only “Updates” from micro-blogs like Twitter, FriendFeed, Jaiku and others.””

“”And, as part of our launch of real-time on Google search, we’ve added “hot topics” to Google Trends to show the most common topics people are publishing to the web in real-time. With this improvement and a series of other interface enhancements, Google Trends is graduating from Labs.””

“”Our real-time search features are based on more than a dozen new search technologies that enable us to monitor more than a billion documents and process hundreds of millions of real-time changes each day. Of course, none of this would be possible without the support of our new partners that we’re announcing today: Facebook, MySpace, FriendFeed, Jaiku and Identi.ca — along with Twitter, which we announced a few weeks ago.””

The new features will be rolling out in the next few days and will be available globally in English. You can try them out today by visiting Google Trends and clicking on a “hot topic,” which in most cases will bring you to a search results page with the new real-time feature.
