Search engine
A search engine, such as Google, is an
online tool that helps users of the World
Wide Web find the sites and information
they're looking for. Most search engines
use automated programs (sometimes
called spiders) to look for relevant
information based on keywords entered
by the user, and search not only web
sites' content but also their web
addresses, number of pages, and links.
Search engines are one of the top ways
users can find your web site or online
store.
