In the fierce competition between the top search engines, a lot of different methods are used to help the search engines achieve their planned market share goals, and while some top search engines are fed by other search engines, others just simply absorb other search engines. For example, Yahoo! owns AllTheWeb, Overture, and AltaVista, while it also owns and uses Inktomi’s technology and database for its partnering engines. Ask owns and uses crawlers and results of the Teoma engine, and DMOZ is owned by Netscape, while Lycos owns HotBot and Tripod, and these possible combinations and correlations allow some of top search engines to effectively compete for a share of the market and other search engines to fight to continue their operations.

Every top search engine, no matter what kind it is, is designed to provide people the most relevant information they search for, and you should arm yourself with the most current and important information to build the knowledge-base you need to climb to the most relevant and highly-ranked places of top search engines.
