What is SEO?

SEO (Search Engine Optimization) is optimizing websites and web pages with search engines. There are about the five most popular search engines on the internet. However, Google holds 95% of the share in all the search engine industry, and we’re sure you also are using Google as your primary search engine.

So, how does Google know which website it needs to rank on corresponding keywords typed by the user? We mean, Google isn’t a human who’ll read and scan all the 1,197,982,359 websites manually.

That’s why Google uses a different strategy and uses an algorithm: “SEO.”

SEO is the optimization of your website with Google’s search engine algorithm, so the crawler of Google’s algorithm can read and scan your website and rank it on their SERPs on corresponding keywords typed by the user on Google.

How Google’s SEO Work in 2021

If you think you can optimize your website SEO by using keywords in your content, you’re wrong. Google used this strategy till 2015; the current Google doesn’t work like that. The company is worth a total of $ 1,928 + billion, and what do you think they did not invest in or upgrade their SEO algorithm despite having that much money?

The algorithm of Google is even more intelligent than we humans, which thoroughly analyzes the webpage, and the algorithm knows which website is doing what even better than the readers.

Below we’ve mentioned updated working tips on how the algorithm of Google SEO works and how you can make your website optimized for Google:

Loading Time

The website’s loading time plays a significant role in the SEO of your website. The users on the internet want to access their desired web pages instantly, and no one has enough free time to wait for your webpage to be loaded. According to research, users wait for about 5 seconds for the web page to load. If the webpage can’t load within 5 seconds, 70% will close the tab and look for other websites. No one owes you a visit.

That’s what Google knows. The algorithm of Google’s SEO is designed to give optimal, smooth, and informative results in its SERPs. That’s why Google only ranks those websites with good and fast loading times. The algorithm will never rank a web page that takes more than 2.1 seconds to load.

So make sure to have a good loading time on your webpage. You can compress the images, remove unwanted themes, elements, and anything that makes your website slow in loading.

Content Quality

Google wants to offer the best and most premium quality web pages in its SERPs to the users. So that users can trust Google that “Google provides us up to the mark content in its SERPs.”

Therefore, the quality of your content matters the most. The algorithm is smart enough to recognize which web page has the best quality content. The algorithm is even more intelligent than humans.

For instance, search anything on Google and see the 1st SERP. You’ll notice that the first SERP of Google contains the most up to the mark, premium, and high-quality content. Google never ranks poor-quality content.

The quality in this section refers to providing informative knowledge in the content, content which increases the information of the user, 100% unique content (not plagiarized), easy to read by the users, content without any grammar mistakes, etc.


Keywords are one of the oldest SEO techniques that Google has used since it was released as a search engine. In SEO, the term “Keyword” refers to the word or phrase users type into Google or other search engines to find what they are looking for.

For example, if the crawler sees keywords: “coffee,” “milk,” “make,” “cup,” “how-to,” and “sugar,” the crawler will know that most probably, the content is about: “how to make coffee.” The algorithm will then start ranking that webpage on the corresponding search keywords typed by the user in the Google search tab, e.g., “how to make coffee.”

However, don’t fluff the keywords too much in the content, which worsens the quality. If you do, Google will put you on the blocklist because you’re trying to manipulate Google and doing blackhat SEO.

Spam Filters

The algorithm is smart enough to recognize which content is doing spam, spreading false information, spreading dangerous and malicious codes to users’ browsers, or doing illegal activities.

Of course, Google is a must-national 100% trusted search engine. Why would Google rank such a website in its SERPs? There’s no reason to do that for Google, nor do they want to hurt the trust of Google in the user’s mind.

If you’re doing any negative, false, or spam work on your website to earn more and fast money, you can, but never expect Google to rank your website in its SERPs. It destroys the SEO of your website because Google is much more intelligent than you; it knows what your website is doing better than the owner. So don’t try to trick Google!

Always do genuine, honest, and legal work, valid for your users and visitors who land on your website. That’s the criteria of Google’s SEO.

Flesch Readability Score

Note: This section is only for web pages that have articles, blogs, or any written content.

Flesch readability score is the score that tells the grade of your writing. It’s measured in the 0-100 and was developed by Rudolf Flesch 70 years earlier.

The higher the score, the easier your content will be easier to read:

90-100: very easy to read, easily understood by an average 10-12-year-old student.

50-60: can be read by a 13-15-year-old kid.

0-20: very difficult to read. Only understandable by Ph.D. grade professionals.

Now, you’re publishing your content on the internet, where every type and every grade of users can read. It’s not intended for professional people only, and any casual reader can read. That’s why you need to make sure that your writing is easy enough that an average 13-15 years old kid: 50 or above Flesch score.

Moreover, Google also ranks those websites which have easy to read text. Because Google isn’t intended for professional writers only, it’s designed for every type of general person. That’s why Google only ranks the web pages with a 50 or above Flesch score.

Myths Regarding Google’s SEO

Of course, Google never reveals the criteria of their SEO algorithm. The whole Google SEO thing on the internet is working on theories, guesses, and experiences, and wherever a guess and theory.

Below is the article, we’ve burst some of the most common myths regarding Google’s SEO:

Keyword Game

Still, in 2021, people think that Google only ranks the websites based on a keyword. It does, but a minimal % of SEO rankings are dependent on the keywords of the webpage.

Look, Google is a $1900+ billion company. Do you think they can’t even develop an advanced AI algorithm close to a human’s reading ability in this considerable budget?

Google’s SEO algorithm doesn’t only rank the web pages based on keywords. The keywords only play a 30% role in the overall SEO rankings.

The algorithm looks for loading speed, content quality, Flesch reading score, information in the content, images in the articles, copyright material, and many other things, covering 70% of Google’s SEO ranking.

Hence, the myth is busted!


Google does prefer content that contains images and visual content. However, adding images is not always compulsory. Look, Google is now a brilliant AI, better than we humans in this case. It knows which content needs ideas and which doesn’t.

For example, you don’t need to add images; it’s not compulsory. On the other hand, in statistics articles, ideas might be mandatory as they help the reader understand the content easily.

Google only follows what the readers like and things that provide the user ease. So follow what other readers want and make their time on your website worthwhile. Google will rank you!

Hence, myth busted!

Bot Traffic

Many new website owners redirect fake bot traffic to gain traffic for SEO. You’re manipulating the system, and Google knows it.

What do you think Google will not recognize? I suppose you might be wrong. Google is way more intelligent and always stays one step ahead of you. It knows when a website has a bot or any fake traffic.

Paid or advertisement traffic is fine. It’s good for SEO, but bot traffic will get you on the blocklist of Google’s SERP.

Do genuine work, Google will rank it, and you’ll get organic real human traffic on your website.

Hence, myth busted!
