How Google Search Engine Algorithm Works? SEO ranking explained

Everyday billions of searches happen on Google on all kinds of things. Sometimes google also gets searches on how google actually works. While this is a topic on which an entire book has to be written, in this post you will get to know about how the Google search engine works step by step.

So, let’s say you are late for the office and you are very hungry. You just planned the last night that you will avoid junk food for this entire week. So, you want to cook something that is both healthy and can be prepared really quickly. Without wasting any further time you search Google for ” Quick and healthy meals” and you get the following search result.

What is Google Algorithm?

Now let’s dive deeper into the whole mechanism and procedure behind this quick search result. Since the beginning when Google was first made, Google has been continuously mapping the web hundreds of billions of pages to create something called an index. Think of it as the giant library that you look through whenever you do a search for “meal recipes” or anything else.

Consider the example of ‘Lasagna’. The word Lasagna shows up a lot on the web. Pages about the history of lasagna, article about scientists whose last name happen to be lasagna. But if you are hungry, random surfing through various pages is no fun. This is where the Google ranking algorithms come into play. First, they try to understand what you are trying to look for and then produce results that are useful even if you don’t know the right words to use or if your spelling is a little off. Then they sift through millions of possible matches in the index and automatically try to put the most relevant information on top for you to choose from.

How does the Google Algorithm Work?

How does the Google algorithm actually decide what must make up to the top page? There are hundreds of factors that go into ranking search results. So, let’s talk about a few of them. You may already know that the pages that contain the word you searched for are more likely to come on the top. The location of the words, whether in the pages title, in the Tags or in the image’s caption are important factors too. There is a lot more to ranking than just words.

Google ranking factors

Back when Google was started, an important factor taken into account was how pages linked each other, to better understand what the pages were about and also to know how trustworthy they were. Linking is still an important factor. Another important factor is location, where the search happens. because if you happen to be in India you might be looking for news relate to your country. When you search for the price of a product that is sold globally, say a smartphone you are most likely to be looking for the price in your country and not the price elsewhere across the globe.

When a web page is uploaded is an important factor too. Pages published recently have more accurate information, especially in the case of rapidly developing news story. Of course, not every website on the web is trying to be useful. Just like the robocalls in your e-mail or spam in your mails, there are a lot of sites that exist just to scam. And everyday, scammers upload millions of them. So just because xyz.net happens to list the keyword 400 times in their post that doesn’t mean it is relevant information.

Google spends a lot of time trying to be one step ahead of tricks like these, making sure the algorithm can recognize scam sites and flag them before they make into the google search results. So, billions of times every day, when someone searches for a dish, say Rasmalai, or how to be a blogger or how to start a business or anything else, Google software tracks all the potentially relevant results on the web, removes all the spam, and ranks them based on hundreds of factors, like keyword density, links, location and freshness.

How does the Google change it’s Algorithms?

Every second the world is changing, news things are discovered, written and searched about. In fact every one in seven search results is something that has never been typed into Google before by anyone. So, the search algorithms are regularly updated and upgraded to meet the needs of the people. This leads to the next question as to how does Google decide which result is more useful and which search is not.

Well ,one of the ways Google evaluates potential updates to their search is by asking feedbacks from users. Everyday millions of search quality raters look at the results of search and then give their feedback on the reliability and the relevance of the information. The feedback is provided on the basis of a Search quality evaluator guidelines. However, the responses form the raters or users have no direct impact on the ranking of any website or webpage on Google.

So, that’s it, every time you are clicking the search button, the Google algorithm tries to analyze what you are trying to search and then matches them to the content on the web, understanding what content is most likely to be helpful and reliable and then automatically putting it all together into one neatly organized page designed to provide you the info in just a few micro seconds.
