I personally am starting to use Meta search engines primarily for the fact that if something ranks high on multiple engines it ranks on the first page of the meta engine. I rarely have to go any deeper than 2 pages to find exactly what I am looking for. there are several out there: www.SearchWorm.com and www.DogPile.com are two for instance I know of. Why would people use a single search algorithm when they can use many at once? Maybe I dont get it.
well if a meta search engine gets poor pages that are ranked high in alot of search engines but not google, then people will want to use google. also they might not have heard of it... the average user can't name more than 4 search engines...
Why would people use a single search algorithm when they can use many at once? Why do you think? Because the general population doesn't know, yet there benefits.
