Search engines: Finding
the needle in the haystack!!
Search engines are
the primary interface between people using the Web and websites.
We
visit a search engine site [like
Google, Yahoo
or Msn] and type
keywords or phrases to find relevant websites. Search engine uses
their technology to find websites that best match the keywords you
are looking for.
Search engines compile
their databases using "spiders" or "robots"
('bots') to crawl through the Internet from link to link, identifying
and perusing pages. After spiders find pages, they pass them on
to another computer program for "indexing." This program
identifies the text, links, and other content in the page and stores
it in the search engine database's files so that the database can
be searched by keyword and whatever more advanced approaches are
offered, and the page will be found if your search matches its content.
Search Engines are
very important for generating traffic to your site. More than 90%
of Internet users use search engines to find products and services
and information that they are looking for. When a search engine
reviews your website, it looks for different types of clues to establish
a ranking.
Some types of pages
or links are excluded from most search engines because of structural
& Technical barriers or search engine spiders cannot access
them. Pages that are excluded are referred to as the "Invisible
Web" -- what you don't see in search engine results.
