How Does Google Work?

If you’ve ever wondered what happens to your posts, tweets or blogs once you press the submit button, wonder no more. This infographic gives you a visual walk-through of what happens when you post anything, in full “gory” detail: from indexing through to ranking and delivery. Here are a few interesting nuggets from the infographic:

It all starts with the web, made up of over 60 trillion individual pages. There are several search engines, but what sets Google apart is how it ranks these pages:

How Google Works:

  • Google crawls the web by following links from page to page
  • Google will only visit the pages it’s invited to: it won’t visit if you use a robots.txt
  • A page’s overall authority is based on the quality of its links and other ‘secret’ factors (algorithms)
  • Search relevance and content quality are fundamental to ranking. And the more links you have from “high authority” pages, the higher your ranking. Google’s trademarked algorithm, called PageRank, assigns a relevancy score to each web page
  • Spam and pirated content are hunted down and taken out by Google, and behaviours such as anchor text manipulation can result in a website being removed from search results
  • Pages and ads are subject to Google’s editorial policy – ads operating outside the policy will probably have their accounts banned
  • Google uses algorithms to try and work out search intention
  • Search results are generated in under a second.

Given the central role of Google in all of our lives, it helps to know how it works – even if not all the information is revealed to us.
