Imagine you are talking to a friend and you mention the word mouse. Is your friend thinking about the small furry animal that eats cheese, or the plastic device you use to click on a computer screen?
Your friend knows the exact answer simply by listening to the other words in your sentence. If you also say the words cheese, trap, and tail, your friend knows you mean the animal. If you say the words screen, click, and keyboard, your friend knows you mean the computer device.
This exact same logic is how Google reads your website. Google is a machine. It does not have a human brain. It uses supporting words to understand the true meaning of your blog post. These supporting words have a special name in the SEO world. They are called LSI Keywords.
If you want your website to rank on the first page of Google, you must learn how to use these supporting words. In this completely simple guide, we will teach you exactly what LSI keywords are, why Google loves them so much, and how you can find them for free to boost your blog traffic.
What Exactly Are LSI Keywords?
LSI stands for Latent Semantic Indexing. You do not need to memorize this complicated computer science term. In plain English, LSI keywords are simply words and phrases that naturally belong together.
They are not direct synonyms. A synonym is a word that means the exact same thing, like happy and joyful. LSI words are different. They are words that frequently appear in the same conversation because they share the same topic.
Let us look at a very clear example. If you write an article about Apple, Google needs to know if you are writing about the red fruit or the famous technology company.
- If your article includes LSI words like juice, sweet, tree, recipe, and healthy, Google instantly knows you are writing about the fruit.
- If your article includes LSI words like iPhone, battery, screen, Steve Jobs, and charger, Google instantly knows you are writing about the technology company.
By adding these related words to your writing, you are giving Google a very clear map of your topic.
Why Does Google Love LSI Keywords?
To understand why these related words are so important, we have to look back at the history of the internet.
Many years ago, people used to trick Google very easily. If someone wanted to rank their website for the word cheap flights, they would just type the words cheap flights five hundred times on a blank page. The search engine robot would see the word repeated over and over again, and it would put that terrible website on page one.
This trick is called keyword stuffing. It ruined the internet because people were getting garbage search results.
The Smart Search Engine Update
Google decided to fix this problem by making their robots much smarter. Today, if you repeat your main keyword fifty times, Google will completely ban your website from the search results.
Instead of counting how many times you repeat one single word, Google now scans your entire page looking for LSI keywords. The computer brain knows that a true expert writing a real article about cheap flights will naturally use related words like airport, luggage, boarding pass, ticket, and travel insurance.
When Google sees these related words scattered beautifully throughout your paragraphs, it rewards your website. It proves to the search engine that your content is high quality, highly educational, and written by a real human being.
How to Find LSI Keywords for Free
You do not need to guess which related words Google wants to see. You also do not need to spend hundreds of dollars on expensive SEO software. You can find these golden words completely for free using two very simple methods.
Method 1: The Bottom of the Google Search Page
Google actually gives you a secret list of related words for absolutely free. Go to the Google homepage and type your main topic into the search bar. Hit the enter key.
Scroll all the way down to the very bottom of the first page. You will see a section labeled Related Searches. Google will display eight different search phrases in blue text. These phrases are the exact LSI keywords that Google associates with your main topic. Write these words down on a piece of paper and make sure to include them in your article.
Method 2: Use the MajhiTools SEO Keyword Generator
If you want to save time and get a much better list, you can use our completely free MajhiTools SEO Keyword Generator. We built this tool specifically to help beginners organize their content.

Our system will provide you with a perfect list of related terms. You can just copy this list and keep it open while you write your blog post.
How to Use LSI Keywords in Your Article
Finding the related words is only step one. Step two is placing them correctly inside your blog post. Many beginners make the mistake of forcing these words into sentences where they do not belong.
Sprinkle Them Naturally Like Salt
Think of your main keyword as the main ingredient of a meal, like rice. Think of your LSI keywords as salt and spices. If you use too much salt, the food tastes terrible. You just need to sprinkle a little bit of salt over the food to make it perfect.
Read your article out loud to yourself. If a related word sounds awkward or robotic when you say it, delete it. Only use the words where they naturally fit into your human conversation.
Use Them in Your Subheadings
Google robots pay very close attention to your H2 and H3 subheadings. Instead of just putting your main keyword in every single heading, use your LSI keywords. This tells Google that your article covers the topic from every possible angle.
For example, if your main article is about Dog Training, your subheadings should include related words. One subheading could be The Best Puppy Treats for Rewards. Another subheading could be Choosing a Strong Leash. Words like treats and leash prove your expertise.
The Golden Rule of Writing
Never write an article just for the search engine robot. The robot will not buy your product. The robot will not click on your advertisements. Always write your article for a living, breathing human being first. After you finish writing for the human, go back and sprinkle a few LSI keywords to make the robot happy.
The Difference Between LSI and Long Tail Keywords
Many new bloggers get confused between long tail keywords and LSI keywords. It is very important to understand the difference so you can use both of them correctly to grow your website.
A long tail keyword is the specific, long sentence you want your entire article to rank for. This is your main goal. For example, How to make black coffee at home is a long tail keyword. This sentence belongs in your main title.
LSI keywords are the short, supporting words hidden inside the paragraphs of that same article. Words like boiling water, sugar, caffeine, and mug are LSI keywords. They do not act as the title. They act as the supporting actors in your movie.
Conclusion
Using LSI keywords is one of the smartest and safest ways to improve your website traffic in 2026. By adding related words and phrases to your articles, you immediately protect your blog from keyword stuffing penalties.
More importantly, you send a massive signal of trust to Google. You prove that your content is deeply researched, highly relevant, and created to truly help the reader. Take a few minutes before you write your next post to gather a list of related words using free tools like MajhiTools. Sprinkle those words naturally throughout your paragraphs and subheadings.
If you make this a daily habit, search engines will reward you with higher rankings, steady free traffic, and a highly successful online business.
