Its very simple to understand this, think of Web as a very large book and with a huge index telling you what is placed where and about everything and then its served to you. Basically three process are performed in delivering search results
  • Crawling
  • Indexing
  • Serving
  1. Crawling is the process by which Googlebot discovers new and updated pages to be added to the Google index.This process is performed by automated computer programs called crawlers/spider/robot/bot
  2. Indexing is the process where the Crawler/spiders compile a huge index of all the crawled pages or words.
  3. Serving is something When a user enters a query, auotmated programs search the index for matching pages and return the results that are most relevant to the user query.
