How Google's Search Engine Really Works (A Peek Under The Hood)

Today half of the world's population access the internet to look for answers to their queries. Today, Google solely conducts more than two trillion searches every day and has completely transformed the way people browse the internet. With many alterations to its algorithms on a daily basis, Google is absolutely the most significant rule setter of the game.

When the founders Larry Page and Sergey Brin first came up with the idea of Google, they had everything planned for the future. In the paper they released back in 1998 at Stanford, they stated how PageRank citation would help arrange the chaos on the internet caused by the increasing web pages. From its very birth, Google has always placed the user's intent and experience on a high pedestal, and to date, it remains the essence of Google's purpose.

What Makes Google The Revolutionist?

Every known name in the search engine league, like Yahoo (founded 1997), Baidu (founded 2000), and Bing (founded 2009), have had almost the same timelines with similar competitions. Google (founded in 1995, formerly known as Backrub), however,Ā  quickly shifted from the slow lane to the fast lane in just two decades.

As mentioned earlier, Google serves its users with the best experience. Google understands that it needs to help people as much as possible, so they return to the search engine whenever they need help.

How Do Search Engines Work?

The primary objective of any search engine is, as the name suggests - searching. You can take the example of a library, where books are arranged according to their subjects in different rows and columns, representing indexes or databases. When you need any book, you simply walk up to the aisle with relevant books and pick out what you think is most helpful for you. Google takes care of all these steps, and the only action you have to take is to search for your problem in the search engine query.

Every search engine principally works through three stages:

A. Crawling

The search engines have crawlers or spiders (Google Bots for Google) that help them analyze the content over the internet. This process of discovering new content gives them an idea about the information your page will provide for their users. The data can be in any format, including texts, images, videos, and PDFs.

B. Indexing

Every search engine also has an index where they store and arrange all the data acquired by them from your website and web pages according to the context where the search engine can use them. Indexing provides your data the visibility it requires to appear as search engine query results.

C. Ranking

The search engines have different factors that define your rank on them, the main aspects being the content, structure, and keyword usage. Ranking simply means ordering the stored data in the most relevant to least relevant fashion.

What Does Google Do Differently?

Google Search is extremely precise in understanding what a website or webpage wants to communicate to its readers. However, if you still wish to choose how Google Bots read and analyze your content, you can select the different filters for the Google Search Console.

Moreover, the AI technology, RankBrain, employed by Google, now intuitively understands what people might be looking for, and that is a massive difference separating Google from its competitor search engines. Using the search history, user behavior, and user interaction on the web browser, Google can piece together all the information about you to provide you with the best answer matching your likes and dislikes.

If you are a movie enthusiast and it sounds too much like J.A.R.V.I.S. from Marvel's Iron Man, you will most likely get the accurate picture. Additionally, you should also note that the privacy policies on Google keep all your data secured and use it only for your provision.

How Does Google Search Algorithm Work?Ā

Google search algorithms have one function: dig deep into the abyss of content available on the internet and return with the most relevant answer to your search query. The significant difference separating Google from other search engines is that its algorithms are so powerful that they do all this within a fraction of a second.

Google algorithms act as a filter to distinguish, rank, and present your answers. For instance, you can open a website for online shopping that views all the products that the seller trades. But to get an accurate product, you would add filters and categorize what precisely you are looking to buy. This job of properly organizing and presenting the data available on the internet is done by the series of algorithms that Google's ranking systems use.

The Google algorithms determine the following key factors to determine relevant search query results:

1. Meaning of the User's Query

If the user searches for a solution, it means they definitely have a problem. Google focuses on the meaning of the user's query, taking care of the different meanings a word can have to provide you with the most relevant result for your query.

2. Web Page Relevance

The algorithms then search for the relevance in the data stored with them and match it to the searched query. The compatibility is compared by matching the keywords in the content to that of the question and machine-learning analysis.

3. E-A-T

The quality of the content and reliability of the information provided by the website is a key factor in determining the ranking. Expertise, authoritativeness, and trustworthiness of a website can be verified by the number of backlinks they earn on other websites with a good E-A-T.

4. Accessibility

The algorithms check if the user can access the site on multiple devices and quickly find the information they are looking for.

5. User Behavior

The user's interaction with different websites, their search history, and geographical location - all help the algorithms figure out the most relevant data on the internet according to their needs.

What is the Role of the Google Search Algorithm?

Google adds minor updates to its algorithm almost every day, but the significant changes that can heavily impact your traffic generation are brought about almost twice a year. Although, as mentioned before, all these updates provided by Google are only to enhance the user experience, whether it is quickly searching for a result or finding the most relevant content on the internet.

Back in December 2020, Google's core algorithm was updated and they added more E-A-T guidelines in the bunch to service users' best interests. It was aimed at more creative, unique, and informative content for your reader.

You can check for these core updates every couple of months and accordingly update your website content.

Here are some places you can get your Google algorithm updates:

How Does Google Find the Best Results for its Users?Ā

These crawlers also organize the content according to their purpose, so it could be used when a related search is conducted. Schema markup also helps the readers swiftly go to the details of the query they need an answer to instead of going through the entire content and wasting their precious time.

3. Page Loading Speed

The search results are provided by Google in a matter of seconds, making it essential that the result it provides should also quickly load when a user opens it. You should ensure that your content loads fast, even if there are many images included.

4. User-Friendly Design

The website or webpage should support the user to check if the webpage quickly provides answers and has enough information. User-friendly design also means that your website is compatible with any device, from a personal computer to a mobile phone. Moreover, the guideline released by Google ensured that mobile-friendly websites would be potential high rankers.

5. Security

Google supports a website that ensures privacy and security for the user's data. In a major guideline release, Google also added to their algorithm that they would support HTTPS more than HTTP because of the security that HTTPS provides.

6. User Behavior

Google algorithm pays minute attention to the way a user interacts with a website. Behaviors will involve total time spent on the website, bounce-back rates, click-throughs, and website usage data.

How to Improve Ranking in SERPs?

Factors that play principal roles in other search engines are easily understood. However, Google updates its algorithms so many times that it is quite hard to stay abreast with the latest changes. Fortunately, some basic concepts never change and can help you optimize your content for the best user experience.

1. Superior Quality Content

It will always be the first factor affecting your ranking in the SERPs. Since the content is the first thing that introduces your viewer to your website, the content is your web page's backbone. Make sure that your content matches user intent and solves their problems.

3. RankBrain

However, Google has so far only used RankBrain as an incorporated factor for its web page ranking system; it is still the third most crucial factor to take care of if you want a higher ranking on SERPs.

4. Visual Aids
