Understanding How A Search Engine Works

in Search-engine
The internet has revolutionized the way in which we communicate and interact one with another. A person on one side of the world can gain access to information held by another person on the other side of the world.

In addition, there is a great potential for communication as well. However, this aspect is still developing and has perhaps not reached the same level of capability as the facet of information.

There are databases online that provide users with free or cheap, searchable indexes of information. Anything that you have ever wanted to know about is at your fingertips.

In a larger sense, the internet itself is a database of information. Not long after the internet was developed, a method for cataloging and indexing the information contained by the World Wide Web was created.

This method gave rise to the internet search engine. A search engine searches the majority of pages found on the internet, and brings back results to a user.

Accomplishing this task may seem monumental due to the massive amount of information that can be found online. It seems no less remarkable when the process is understood, but it at least becomes comprehensible.

Search engine's employ Web crawlers. These programs are similar to browsers, but are able to follow every link contained on a website without human intervention.

The crawler is able to do this at a high rate of speed. As the crawler follows the links, it begins to index the content of each page.

Key words are taken from the text of each page. These key words are then stored by the search engine.

A certain amount of content is stored to improve the speed of recall of this information. The amount of content that is stored depends on the search engine.

In some cases, the page will have been updated, but only the content found by the search engine during its initial search will be displayed to the user. In this way, only information relating to the search terms entered by the searcher will be returned by the search engine.

When a user does conduct a search using a search engine, they do so by entering a word, group of words, or phrase. The search engine utilizes these key words to check for relevant websites.

A page containing these exact, or at least similar, key words will be returned on the search results page. Relevancy is the primary criterion used by many search engines when creating search results pages.

Boolean operators may be used as well to enhance the search process. These connectors tell the search engine what to include or remove from the search parameters.

There is, however, another criterion that does hold a certain amount of sway. This criterion is popularity, or authority.

A page will be deemed more popular and authoritative on a subject when it has many links to it. Thus, pages with more links on other sites that direct an internet user to the page will be ranked higher in a search results page than one with fewer.

It is important, then, to be recognized as an authoritative site on a subject, but it is even more important to use the right words in the content of a website. If you do not use the most commonly searched for terms, your website will not appear anywhere near the top of a search results page.

Employing the right key words can help you to be found by those who most need the information found on your website. This is especially important for businesses that want to gain more clients.

There are firms that specialize in assisting companies in employing the right language on their websites. By altering the content of a company's website, these firms allow that company to be found by those who are in need of their products or services.

Learning how to choose the right keywords is vital to a company's success. Only by including terms commonly used by searchers will they attract potential clients.

If your company is trying to gain notoriety online, take the time to learn what the public is searching for in regards to your field. It will be one of the best investments you have made in a long time!
