Search engines have the main purpose to index thousands of
millions of web pages. Once you look for a word or a phrase, the
search engine scans automatically the entire database where it
has the stored pages indexed and it returns to you as a result a
list containing the most relevant results for that search.
The only criteria are the number of pages found and their
relevance depend on are the capabilities of the used search
engine.Google has become the largest search engine at present
but there is a constant battle between companies to be at the
forefront .
Search engines appeared somewhere in the early 90's when Alan
Emtage, a student at the McGill University in Montreal created
the first search engine tool. It was called Archie. Its purpose
was to search through the information available on the FTP
servers. The files on these servers were available for anyone,
but one couldn't use them unless knowing the exact address of
the server and of the file.
Archie looked through this database and gathered lists of files
for each server. It was used by people to match phrases and
characters in order to take them to the server address the file
they were looking for was on.
Its creation was the first step in the search engine rally that
is going on now. As the public grew more and more aware of the
existence of the internet, the need for a search tool became
visible.
So, first there were some software robots, using the concept of
spidering to index the web, following links from one site to the
other and saving the text from all visited websites in a
database.
Between 1994 and 1995 three important search engines appeared:
Lycos, WebCrawler and AltaVista. At about the same time Yahoo!
appeared but Yahoo! is not a search engine. Yes, it has a search
engine function, but yahoo is firstly a directory of data and
articles, providing different services as email and hosting.
Recently yahoo has signed contracts with other search engines as
Google for both of them to provide more search results.
Today search engines are in a continuous competition. There are
thousands of search engines, but just a few big ones. This small
group of top search engines is responsible for more than 90% of
online searches.
However, if search engines are free and they can be used by
everyone what keeps them financially alive? The answer to the
question is very simple: advertising and traffic. The more
visits they have, the bigger the traffic then the more money
they can make providing AD space.
Search engines are competing to develop the best formulas and
algorithms to evaluate the web pages accordingly to the keywords
provided.
If someone is looking for a top position in search engines, then
he has to be sure that his site is projected in such a way that
search engines would find it easily, being relevant for the
keywords and phrases the owner wants it to be found by.
