Following on the heels of Bing's announcement earlier Wednesday at the Web 2.0 Summit in San Francisco that it would aggregate real-time search results from social-networking services Facebook and Twitter, Google got into the act.

Vice president of search products and user experience Marissa Mayer announced on The Official Google Blog that the search-engine giant will include tweets in its search results.

Mayer wrote:

At Google, our goal is to create the most comprehensive, relevant and fast search in the world. In the past few years, an entirely new type of data has emerged—real-time updates like those on Twitter have appeared not only as a way for people to communicate their thoughts and feelings, but also as an interesting source of data about what is happening right now in regard to a particular topic.

Given this new type of information and its value to search, we are very excited to announce that we have reached an agreement with Twitter to include their updates in our search results. We believe that our search results and user experience will greatly benefit from the inclusion of this up-to-the-minute data, and we look forward to having a product that showcases how tweets can make search better in the coming months. That way, the next time you search for something that can be aided by a real-time observation, say, snow conditions at your favorite ski resort, you'll find tweets from other users who are there and sharing the latest and greatest information.

And Twitter CEO Evan Williams added on the social-networking site's blog:

Our friends down in Mountain View want to organize the world's information and make it universally accessible and useful. A fast-growing amount of information is coursing through Twitter very quickly, and we want there to be many ways to access that information. As part of that effort, we've partnered with Google to index the entire world of public tweets as fast as possible and present them to their users in an organized and relevant fashion.

We've always taken an open approach to how people experience Twitter, particularly in how and where tweets are read. Users have benefited greatly from the abundance of choice provided by our ecosystem partners. We're honored to take this next step with Google and tap into their expertise to support the rapid, open exchange of information.
