Dogpile: Relevance in Aggregate

* Only 0.6% of 776,435 first-page search results were the same across the top four Web search engines

* Between 38% and 46% of all searches fail to elicit a click on a first-page search result, don't meet users needs and drive users to try additional engines.

* Web searchers on average use three search engines a month

* Search result rankings differ significantly across major search engines; only 3.6 percent of the number-one ranked, non-sponsored search results were the same across all search engines in a given query

"This study reinforces what we at InfoSpace have long known - often users do not find the results they need with any single search engine. Metasearch offers the most robust and efficient search solution to meet their needs," said Rod Diefendorf, vice president of online and local search at InfoSpace. "With less than one percent overlap in first page results, there is great value to using a metasearch engine like Dogpile.com to quickly comb through multiple search engines at once for the most relevant results."
