Whenever we want to find information about something, our first step is to utilize a search engine because it is the easiest and fastest way to get that information. When the search results are shown, we are more likely to inspect the links on the first page of search results because these links are closely connected to what we are looking for and allow us to find easily what we are looking for.

The URL would then “crawled” by “spiders” to take out links to other webpages from that webpage and this process would index that webpage with returned data. This process consist of downloading and keeping the webpage by search engine spiders on their servers, Then another program which is called “indexer” grabs various details about that webpage – how many words that webpage has and the location of these words, all the links that webpage has, Which afterwards positioned into scheduler to crawl them at a current date.
