Twitter has announced new deals with Microsoft and Google to integrate tweets into standard search results.

The company used the Web 2.0 Summit 2009 in San Francisco to announce that it had signed a deal to allow searching of tweets by Microsoft's Bing and Google's search engines. Microsoft has also announced a similar deal to allow searching of Facebook results using Bing.

"Today at Web 2.0 we announced that, working with those clever birds over at Twitter, we now have access to the entire public Twitter feed and have a beta of Bing Twitter search for you to play with (in the US, for now). The Bing and Twitter teams want to know what you think," said Paul Yiu of Microsoft's Bing Social Search Team.

Twitter content will also be appearing in Google's search engine results in a similar deal announced today.

"Our friends down in Mountain View want to organise the world's information and make it universally accessible and useful," said Twitter in a blog post.

"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 users in an organised and relevant fashion."

Twitter results will be added to Bing today, and Google will integrate them in the next few months.

"At Google, our goal is to create the most comprehensive, relevant and fast search in the world," said Marissa Mayer, vice president of search products and user experience at Google.

"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 as an interesting source of data about what is happening right now in regard to a particular topic."
