Search Engines
A Web site that
automatically gathers and maintains information about all of the Web sites on
the Web.
Each Web search engine uses a different method to index the Web, so your search
results using different search engines might vary. In addition to using
indexing, some search engines, such as Yahoo!, list Web sites by category. Other
search engines, such as AltaVista, Excite, and HotBot, search the Web for new
sites and compile data about the information contained within each site.
Most search engines gather information about Web sites by collecting data based
on META tags entered into the HTML document by the Web page's developer. A META
tag is an HTML tag including text (words describing the site) that identifies
how the Web page's developer wants to add the Web site to a search engine's
index.
