Search engines have three major functions; they provide search users with a ranking list of sites. The major functions of a Search Engine are as follows:

1. Crawling

  • Google uses automated programs called spiders or crawlers.
  • This program generally browses the internet and stores info about the pages it visits.
  • The web crawler makes a copy of the webpage, whenever it visits and adds the webpage urn to the index.
  • After this, the web crawler, repeats the process of copying, and indexing and follows each link on the web page. It keeps doing this, building a huge index of several web pages as it belongs

2. Indexing:

  • Every time a web crawler visits a page makes a copy of it and adds its URL to an index.
  • This process of adding curls to the index is known as indexing. The web crawler repeats the process of copying and indexing. It follows each link on the webpage.
  • So, it’s important to link every page of your website with others.
  • If your webpage isn’t linked & not submitted to google it will not index the page.
  • Robots.txt will help if you want to hide any specific pages from google crawling and still the user can use the webpage.


Google shows results on its search engine results page (SERP) in a sequence with an algorithm, which assigns every Web page with a relevancy score. This process is also known as PageRank.
