SEARCH ENGINES – WHAT ARE THEY REALLY?

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 the number of pages found and their relevance depend on are the capabilities of the used search engine.

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 like too. 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.

Archie is now an old method, but 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 director or 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.

But the question arises: if search engines are free and they cam 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 promotion 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.

Search Engine Friendly Pages

There is no point in building a website unless there are visitors coming in. A major source of traffic for most sites on the Internet is search engines like Google, Yahoo!, MSN, Altavista and so on. Hence, by designing a search engine friendly site, you will be able to rank easily in search engines and obtain more visitors.

Major search engines use programs called crawlers or robots to index websites to list on their search result pages. They follow links to a page, reads the content of the page and record it in their own database, pulling up the listing as people search for it.

If you want to make your site indexed easily, you should avoid using frames on your website. Frames will only confuse search engine robots and they might even abandon your site because of that. Moreover, frames make it difficult for users to bookmark a specific page on your site without using long, complicated scripts.

Do not present important information in Flash movies or in images. Search engine robots can only read text on your source code so if you present important words in Flash movies and images rather than textual form, your search engine ranking will be affected dramatically.

Use meta tags accordingly on each and every page of your site so that search engine robots know at first glance what that particular page is about and whether or not to index it. By using meta tags, you are making the search engine robot's job easier so they will crawl and index your site more frequently.

Stop using wrong HTML tags like to style your page. Use CSS (Cascading Style Sheets) instead because they are more effective and efficient. By using CSS, you can eliminate redundant HTML tags and make your pages much lighter and faster to load.
