Spider-based serach engines
Search engines use a form of software program called spiders or crawlers to find information on the Internet and store it for search results in giant databases or indexes. Some spiders record every word on a Web site for their respective indexes, while others only report certain keywords listed in title tags or meta tags.

Directory-based search engines
Sites use human editors to provide results to searchers Some directory-based engines charge a fee for a site to be reviewed for potential listing In the early 2000s, more leading search engines were relying on human editors in combination with findings obtained with spiders. LookSmart, Lycos, AltaVista, MSN, Excite and AOL Search relied on providers of directory data to make their search results more meaningful

Link-based search engines
Search engine provides results based on hypertext links between sites. Sites are ranked based on the quality and quantity of other Web sites linked to them. The emergence of this kind of search engine called for companies to develop link-building strategies. By finding out which sites are listed in results for a certain product category in a link-based engine, a company could then contact the sites' owners—assuming they aren't competitors—and ask them for a link. This often involves reciprocal linking, where each company agrees to include links to the other's site.
