So after viewing the above infographic you would have got a clear about how Google search engine works. The search engine do not search the entire World Wide Web but it only searches the web pages that it has indexed. Google search engine algorithm work in the following manner.


The search engine basically does two things, Crawling and Indexing. Google search engine crawls out to new web pages with the help of its software programs called as “Web Crawlers” or Spiders. A spiders job is to find new web pages and follow the links that are available on those webpage’s.   After the spiders have crawled through webpage’s the second part is indexing. Indexing is nothing different than the index we have in our book, but Google does indexing in a very big way. Suppose the spiders have crawled towards a web page, it indexes the web page according to its content. This indexed page is further stored on Google’s servers. Google’s index is already over 1,000,000,000 Gigabytes.


When you type a particular keyword in the search box, Google search engine searches that keyword from billions of the web pages it has indexed. Google search engine checks whether the key word you have entered is

  • Present in the title or url of a page


  • The number of times the keyword is used on that page.


  • The page rank of that particular page


  • Page contains synonyms for the keyword.



Google search engine takes all these 4 factors into consideration, sorts the data (in the form of images video, text etc) and then provides users with the best possible search results.

The above video would have given you a clear cut idea as to how Google spiders search webpages and indexes them.

Google search started in 1997. 17 years back Google search engine was not as advanced as it today. And so here is a video in which Google’s top executives explain how the Google search has actually evolved through the years. The video shows how Google went from just a search engine to a “Universal Search” engine.

We hope that this post would really help you in understanding Google crawlers (spiders), index pages, Google algorithm and how they work together to give you the best search result possible.
