DOGPILE.COM FIRST TO COMBINE SEARCH RESULTS FROM MSN SEARCH WITH GOOGLE, YAHOO AND ASK JEEVES

With the Addition of MSN Search, Dogpile.com Users Can Efficiently Find More of the Web’s Most Relevant Search Results in One Place

BELLEVUE, Wash. – August 2, 2005 – Dogpile.com today announced that search results from MSN Search are now available on the Web’s leading metasearch engine. By becoming the first to combine results from the four leading search sites-MSN Search, Google, Yahoo and Ask Jeeves-Dogpile.com gives consumers the most comprehensive view of the Web and helps them efficiently retrieve the most relevant results.

The addition of MSN Search to Dogpile.com further extends Dogpile.com’s differentiation from any single search engine. Most people believe search results across all four engines are the same, when, in fact, the vast majority of the results from each engine are different. According to a new study, researchers at the University of Pittsburgh and the Pennsylvania State University evaluated 12,570 random queries run on MSN Search, Google, Yahoo and Ask Jeeves. They found only 1.1 percent of the first page results are the same across all four engines. The full results of the study can be found at http://CompareSearchEngines.dogpile.com/whitepaper.

“By bringing together the best results from the top engines on Dogpile.com, consumers can be confident they are receiving the most relevant results,” said Brian Bowman, vice president of marketing and product management for InfoSpace Search & Directory.

Dogpile.com has built a tool that allows consumers to compare the results of the leading engines for themselves. The new comparison search tool can be found at http://CompareSearchEngines.dogpile.com.

“Dogpile.com now has direct access to the first search engine built from the ground up with Microsoft technology,” said Lisa Gurry, group product manager of MSN Search. “Our collaboration with Dogpile.com represents the first distribution agreement we’ve signed with a metasearch company and is a powerful distribution channel that will help us extend the reach of MSN Search.”
