There are thousands millions of WebPages available over the internet. The content, title of each pages are upto the authors choice, but google show very effective results by arranging all the WebPages. Lets see how google is arranging the things and showing us the results.
Spider software or crawlers are the software developed by google with certain algorithm, which search all over the world wide web for various information of different web pages.

This spider is nothing but an automated software which crawel all over the webpages of various websites and submit the pages to search engine. The hyper links, keywords, information present in various web pages are fetched by the spider.
There are billions of web pages placed over a large number of machines. Crawler separates the information on site pages from sites and stores it in a page storehouse. At that point information is sent to an indexing module, which strips the substance from these pages and removes key components like Meta title, Meta description, information about pictures and interior links. It then puts the information in a database alluded to as list. Every one of these exercises go on constantly, paying little mind to whether an inquiry is made for pursuit or not.
