A Brief Description of What a Search Engine is
What is a Search Engine?
A search engine is software that scours the Internet collecting
data about every web site and every web page within a web
page that it can. Each link that is encountered along the
way is added to a list of pages to be scanned. This type of
software has a lot of different names like a bot, a robot,
a crawler or a spider. It takes all this collected data and
stores it in a huge database. When you do a search on a "search
engine" you are actually searching its database and not
the actual Internet. Like many terms used on the Internet
and computers in general this term is often misused and abused.
For the sake of our discussion here well call the "Search
Engine" the piece of software that scours the web day
and night updating its database.
How Does a Search Engine Work?
Basically the search engines read pages that have been submitted
to it via a submission form. From there it reads the entire
page, boils it down to essential keywords and adds all the
links it finds to the search list. Then it takes the next
page off the list and starts all over again. You can see that
just one submission to a search engine can generate thousands
of pages in its database. All pages on the Internet are subject
to being scanned by a search engine. If you dont want
your pages to be scanned you have to take steps to prevent
it. You can do this with Meta Tags or a small file named robot.txt
located on your site.
How Does a Search Engine Rate a Website?
No one knows. "WHAT?!?!" I hear you thinking.
"I came here to find out how a search engine works."
Well the simple fact is that every search engine does things
a little bit differently and the method for collecting, cataloging
and rating the data that it does have changes probably on
a daily base. Also the people who create these search engines
would rather not tell us how its all done. If I told
you how to get your site at the top of search engines would
you? Most people would say yes. Be honest now, does your site
belong at the top of the search engines? Is it the best site
in your category? If not, youd be cheating the system,
and thats what the creators of these search engines
hope to prevent. Remember this is just software lurking around
the Internet trying to determine which sites are the most
relevant to any particular search query that they get at some
future time. Basically what they hope to be able to come up
with is a system that brings the most relevant and substantial
site to the top of each query no matter what the category
