A Basic Understanding of Internet Search Engines One of the most basic fact that you need to know about the internet search engine is that this is a database system that has been designed to categorize and index the internet addresses. Another basic fact that you need to know about the internet search engine is that it comes in four basic types. The first type of internet search engine that will be discussed is the automatic. This is the kind that is based on information that analyzes, collects and sorts them with the use of software programs. Regarding the software programs, there are terms that are being commonly used and these are the crawlers, robots and spiders. In order to be able to collect information, what the spiders do is that they will crawl through the web pages. The information that has been collected will then be categorized as index after it has been analyzed. If you are searching for something with the use of the internet search engine, what you are actually doing is that you are searching the index. The relevancy of your query and the contents of the index are in fact the basis of the kind of results that you will have. The second kind of internet search engine that you should know of is none other than what is called as the directories. This is the kind of internet search engine that has web sites compiled and reviewed by the human editors. These human editors are the ones that decide which sites belong to what categories and list. Understanding Programs Moving on to the third internet search engine that you should know of and this is called as the meta search engine. There is an automated technology that is being used by the meta search engine. So that information may be gathered from the crawlers there is a need to make use of this kind of technology. The researcher will now be able to have a summary of the gathered information in the form of results. Figuring Out Programs The fourth internet search engine is called as the pay per click or PPC for short. The dollar amount that you will pay will be the basis of your ranking with the pay per click. This means that the highest ranking will of course be given to the highest bidder. Another basic fact that you need to know about the internet search engine is that they make use of the spiders so that they will be able to compile their database. In order to be able to identify web pages, the spiders will crawl through the internet. The content of the web pages will be indexed which is why the internet users will now be able to have URLs.
