Search engines have the main purpose to index thousands of millions of web pages. If you look for a word or phrase, they scan the whole database where stored pages are indexed and finally return to you a list of what they cosider the most relevant results for that search.

Search engines made their appearance in the early 90’s when Alan Emtage, a student at Montreal’s McGill University created the first kind of them. He called it Archie and its purpose was to search through the information available on the FTP servers. In fact, files on FTP servers were publically available , but to use them people had to know the exact address of the server and of the file. Archie looked through this database and gathered lists of files for each server.

Archie is now a very old remembrance, but its creation was for surev the first step in search engines’ adventure.

With the mass- diffusion of the net, search engines became a real need.

As a consequence, they born some software robots, which, spidering the web, following links from one site to the other, used to save 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 too.

Today search engines are in a continuous competition. There are plenty of them, but just a few big ones which are responsible for more than 90% of online searches.

But the question arises: if search engines are free and publically available what keeps them financially alive? The answer is very simple: advertising and traffic. The more visits they have, the bigger the traffic they have and the much more money they make providing advertising spaces.

Moreover, today search engines are competing to find and use the best formulas and algorithms to evaluate web pages in accord to the search keywords.

People looking for a top position in search engines,use an always increasind attention to project and develop sites which can be easily spidered by search engines, being relevant for the keywords and phrases the owner wants it to be found by.

Moreover, there’re daily discussion about the relevance of a catchy domain name in search engines indexing. Nowadays domain names is a daily increasing business, as much as there are a lot of sites dealing exclusively with it.
