How Search Engine Works

When someone strokes on entering placing a keyword in the Search Engine, then he finds millions of search pages, these are actually appearing from the previously gathered or indexed databases of HTML documents done by robots. Basically three types of search mechanism is being used in Search Engine are powered by Spider or Robot, Human submissions and cross breed or mixed of both.

A Search Engine powered by Spider works with an automated program agent is called Crawler or Robot. It visits web sites, reads the site content and Meta tags as well as goes through the links to index all pages or sites as per connection. The spider deposits all this information in index center and periodically keeps revising the information as per further changes in the true sites. How frequently a spider will re-crawl the sites depends upon administrators of the Search Engine.

When a Search Engine is based on Human, then it works for submission of information by human. Later on all information whose are submitted exactly, only they get indexed and cataloged.

In hybrid mechanism, crawling and indexing as well as operation of human submission both sides keep up the database up to date in purpose of someone’s significant responding query results. Since search results are on the basis of deposit index updated by robot frequently following the subsequent links, then dead links are also the result of the updated index.

So, its ultimate question that why different results are shown by different Search Engines in same keyword. Briefly answer is, every Search Engine is not designed following same data relevancy algorithm and data submission. That’s why spider or robot’s design as well as indexing database is different.
