“Search engine is a software program designed to identify and response questions, called Keywords and Populate the page called as SERP with relevant information available on web”

We have unlimited websites available and we want certain information, when we need certain information what we do is search on the web. Only available facility available for as web through the search engine. Now what search engine basically do actually their respond to a certain question that the user as posed called a keyword.

What search engines are the bots are basically do is they first takes the Crawling, They do the Crawling, Crawling in the sense that they spider is send, the robot is send, bots is spend. So, that the information is actually collected from the different pages from the website that are available on the web. On the web you had billions and billions of websites. What search engine basically they crawl those phases and when the Crawling does it actually collects all the information that it has collected on the web and indexes it. Indexes is it a huge server, it is actually a place where the collected crawled information is stored that is the Indexing that is the second part.

The third part is the Retrieval. When the whole content is stored after indexing what the search engine do is, that information is picked up and displayed for the users when the users asked sudden questions on the search engines. Typing a particular keyword that information related to that particular keyword is retrieved and display it for the users.
