How Does Google Work?

Can You confidently say that your daily research for anything and everything has nothing to do with Google? I don’t think so not in the world since after Google was born. Today every search starts with Google because now Google has come so far that it becomes practically impossible for everyone in the world to find out stuff that you need instantly while browsing the web. After all searching is a constant process happening every moment of the day and Google perfectly handles all those millions of search queries. It’s time we talk about the functioning of Google.

Almost of us all probably know that Google work on certain algorithm to generate heavy search results within no time. It’s time we learn the mechanism applied by Google to deliver relevant results. Google has shared its general working procedure with the world only not specific policies which still stays to be secret safe with them staying competitive with other search engines and simultaneously reduces the chances of finding how how to abuse the system by anyone.

Like every other search engine Google also uses certain automated programs known as spiders or crawlers. Google possesses a large index of keywords and where those words can be found but what is different about  Google is the way it ranks search results, which then determines the order of results displayed on the SERP (Search Engine Page Result). In Google’s own language, “The Search starts with the web which is made up of over 60 Trillion individual pages and which seems grow continuously. Google handles the web by crawling which means it follows from page to page but in an unmeasurable speed.

Google has got a trademarked algorithm called Pagerank which provides a relevancy score to each web page. Let’s have a look on what factors does a Page’s Pagerank depends.

  • Keyword frequency and it’s location within the Web Page – If Google finds out that the word(keyword) has only appeared once or twice in the web page, it will assign a very low score to that page.

  • The Age of The Web Page – This is a strong point on which Google’s algorithm depends which finds out for how long the page has been existing. People tend to create new web pages every now and then which apparently doesn’t last long. Google assigns more value only to the pages with an established history, for example your landing page probably will have more PR than your other pages.

  • Other Web Pages That link to the Page asked to be searched – What Google really looks at to determine relevance is that how many web pages are actually linking to a particular website.

Google Ranks the results using over 200 more factors like Page and Site quality, freshness, safe search, user context and many more. Google keeps on changing algorithms very often based on the ideas of it’s engineers. These engineers convert ideas into actually working algorithms by testing it, analyzing the results, tweaking it and running them again and again.

Results are displayed in various forms like pages, maps, images, videos etc. and all this happens in 1/8th of a second. The user context is translated and then it performs universal search and finally display relevant results. A lot of search queries are generated every moment of every day and hence spam becomes a part of it naturally. So, how Google fights spam with all its other search related work going on and to keep the search results as relevant as possible, let’s have a look.

  • Types Of Spam – Hidden text and keyword stuffing, comment(user generated) spam, parked domains, thin content, unnatural links and more.

  • Google’s Fightback System – Google has got a very strong system that fights span 24×7. Most of the spam removal takes place automatically and other questionable documents are examined manually and if found spam then immediate manual action is taken against it.

  • After Action Take – After the action is taken Google then notifies the website/page owners to make necessary changes. The Website/page owners can then fix whatever problem was there and report back to Google for consideration and if found fit Google assigns relevancy score to it.
