How Google Search Engine Works

In this article we will only focus on Google's Search Engine. Remember that all Search Engines are not same.


An everyday person comes on Google with billions of questions about all kinds of things. 

Some time people ask about Google Search itself like how this whole thing actually works. 


Well this is a subject entire books have been written about. There’s a good chance you’re in the market for something a little more concise. 


So let’s say it’s getting close to dinner and you want a recipe for lasagna. You have probably seen a list of search appears on there after clicking the search option. Let’s go deeper.

What is Index ?

Earlier when the homepage looked very simple since then Google has been continuously mapping the web and among hundreds of billions of pages to create something called an index. 


Think of it as the giant library we look through whenever we do a search for lasagna or anything else. Now the word lasagna shows up a lot on the web pages. It shows about the history of lasagna, articles by scientist whose last name happened to be “Lasagna”, stuff other people might be looking for. But if we are hungry, randomly clicking through millions of links is no fun. 


This is where Google’s ranking algorithms come into play.


First, they try to understand what you’re looking for, so they can be helpful even if you don’t know exactly the right words use, or if your spelling is a little off.


Then they shift through millions of possible matching index, and automatically assemble a page that tries to put the most relevant information up top, for you to choose from. Then you have the results which are shown up.

How Google Ranks Web Pages ? Conditions for Ranking

How do the Google algorithms actually decide which page should be ranked and why it should be ranked on the first page ? There are more than hundreds of factors that falls under Google's ranking  algorithm. Let’s know about  of them.

• Keywords

You may already know that pages containing the word you searched for are more likely to end up at the top. But the location of those words, like, in the page’s title, or in an image’s caption. These are factors too.


There’s a lot more to ranking than to adjust words. Back when Google started, they looked at how pages linked to each other to better understand what pages were about and how important and trustworthy they seemed. Today also linking is still one of the most important factor.

• Searcher's Location

One the most important factor is the Searcher's Location i.e. from where a search happens. This is because if you are in Ormea which is in Italy, then you must be looking for information about their annual lasagna festival, but if you’re in Omaha, which is in Nebrasaka,  then you probably aren't looking for that.

• When a Web Page was Uploaded 

The time when the page  uploaded. It is also an important factor because pages published more recently often have more accurate information, especially in the case of rapidly developing news story.

How Google Remove Scam Sites ?

Every site on the internet is not helpful. Some of them are just for scam. Just like robocalls in your phone or spam in your email inbox. There are a lot of sites that only exists for money extortion by scamming. Every day, scammers upload millions of such pages which seems to be very helpful from outside but they aren't so. 


So just because instantvirusdownload.net contains the words “lasagna” 400 times, that doesn’t mean it’s going to help you make dinner, it's just scam. Listing the word 400 times is just keyword stuffing in order to rank in SERP. So that it can attract more and more visitors to its sites.


Google spend a lot of time trying to stay one step ahead of tricks like these, making sure Google’s algorithms can recognize scam sites and flag them before they make it to your Search results page.


So, they review billions of times a day, whenever someone searches lasagna, or “resume writing tips” or “how to swaddle a baby” or anything else. 


Google is smart enough. It's software locates all the trusted and relevant results on the web. It removes all the spam websites and suspicious websites and web pages.


It ranks  websites and pages based on hundreds of factors like keywords, links, location, and freshness. It also removes the websites with spamming links.

How Google make Changes to Search and it’s Importance 

Since 1998, when Google went online, visitors seem to have found its results very much helpful. But, the web is constantly changing, and people are so much creative that they are always searching for new stuffs in fact. One in every seven searches is for something that’s never been typed into the search bar before, by anyone ever. 


So, Google is always working on updates to its Search Engines. Almosy thousands of updates every year which brings up a big question that


Q. How do Google decide whether a change is making Search more helpful ?


Well, one of the ways Google evaluate potential updates to Search is by asking people like us.  Every day, thousands of Search Quality Raters look at sample of search results side-by-side, they give feedback about the relevance and reliability of the information.


To make sure those evaluations are consistent, the raters follow a list of Search Quality Evaluator Guidelines. Think of them as their publicly available guide to what makes a good result best.

One Last Thing to Remember about Google

Google use responses from Raters to evaluate changes, but they don’t directly impact how Search results are ranked.  


Every time you click “search”, their algorithms are analyzing the meaning of the words in your search, matching them to content on the web, understanding what content is most likely to be helpful and reliable, and the automatically putting it all together in a neatly organized page designed to get you to the info you need.
