How Search engine works

Today I will let u know how the search engines exactly works.As u all know that search engines have their own software’s know as bots or spiders\ crawlers.What this software’s usually use to do is that they crawl each page of the site and index them in their database, and this software’s are programmed so well that u cannot imagine it.
They collect each information of the page and index them as per categories in their database. You must have seen when u search for any keyword it will take u to the inner pages of the sites it is not compulsory that it will take to home page of the sites.


Ex: The particular search is done for [ Search Engine Optimization ] keyword and the result comes out.


Therefore, u can imagine how intelligently search engine works.When u search for a particular queries search goes to its database, which is index as per categories it searches for related category and gives u exact result for the query.Ex: U search for the keyword [car insurance] it will show each result, which is, related to car it may be information, car insurance or may be car-selling sites, but if u type same keyword in quotes “car insurance” it will show result related to only car insurance.
Search engine process
ð Crawling => collects information from the sites.
ð Indexing => then index the pages as per categories.
ð Queries => then the user searches for the queries.
ð Results => at last it shows result by using it’s intelligent.
