The most popular Search Engine on the web, Google employs mathematical analysis of over a billion possible hyperlinks in order to bring you a result list based on popularity of sites and their relevancy to the search terms you've used. They rank sites by the amount of links attached to them, which means that more popular sites, not necessarily better quality sites, are given an advantage. Google also provides advertisers a chance to list "Sponsored Links" which are tied to relevant key words but are given optimum placement on a purchase basis.
Established in 1995, Altavista was the first index on the WWW. It provides text and multimedia searching (MP3, video, etc.) of US and international sites. It also offers advanced translations through Babblefish. This engine is very fast, but huge and superfluous returns can take you a long time to sift through.
Ask.com was created with the merger of Ask Jeeves and Teoma. This database doesn't rank sites higher that have the most links leading to them, like Google. Rather, it analyzes sites on the Web by how these sites are naturally grouped as communities within their subject area or approximate subject area. This technology enables Ask.com to provide results with greater precision. However, the quality of your search still depends on the terms and phrases you use.
