How Do I Find My LSI Keywords? 3 Tools And 1 Free Method

LSI keywords have huge significance in SEO. Once I realized the importance, it changed the way I was writing and my SEO technique too.

Earlier, I was working on a traditional blogging site – focusing on a keyword in the article and ranking with backlinks. Once I realized how the Google algorithm might work, I realized that it’s content, not backlinks. So, I started focusing on the content.

With quality content, you can gain Google’s attention.

Quality content is always automatically optimized and clear.

Say you are an SEO expert and you are discussing keywords, you will touch on all the aspects of keywords – meaning, types, trends, and many other things.

The reader will realize that you know the topic well. Isn’t it so?

This is how Google analyzes the content.

If someone is using relevant terms it means he has expertise on the topic.

So what to do when you are not an expert?

If you are not an expert or a freelance writer, you can find the relevant terms and add to the article to pretend to be an expert.

Those relevant terms are called LSI keywords.

Makes sense?

To make you understand even better let’s start with the definition.

LSI keywords Definition

LSI keywords stand for Latent Semantic Indexing keywords. The LSI program is used to find extremely relevant words/phrases to better understand the content according to the context.

So the better the LSI you use, the clearer you make it for search engines.

I have experienced it with 100s of articles that the Google algorithm weighs too much emphasis on LSI keywords. The reason is that Google wants to present the best content to its users. So they want to make sure that the content has the best content before putting it in front of the user.

If we research deeply how Google is treating LSI keywords. Putting other benefits aside, we can say that the best biggest benefit of using LSI keywords is that you can easily rank on Google.

Here is why.

Once someone searches the query, Google wants to understand each query. Surely, the team can’t manually explain every keyword to Google. So they must be using a program (LSI) that helps Google understand the keyword and its intent.

If you could find those keywords and insert them throughout your content, you have already passed the Google best content test.

The rest is the remaining SEO.

Experiment with LSI keywords

Here is an experiment I had done a few months ago.

This article was stuck on page 3rd for a long. I was trying hard to get it on the first page – preferably position 1. I was sure that I have better content than others.

But it was not working.

One day, I thought to find all the LSI keywords for the article. I added more content and optimize the article for LSI keywords.

It’s now among the top positions.

So if your rankings are stuck, most probably, you need to add LSI keywords.

The best techniques to find LSI keywords

Frankly speaking, it’s not hard to find LSI keywords. Most of the time, you can do it with one click.

There are many options to find relevant queries for your article. Let me tell you how I find my LSI keywords and why I get results for 70%-80% of my articles.

As being human I can, too, make mistakes. But tools make more mistakes than I do. That’s why it’s better to learn to find LSI keywords with tools and without tools.

Here are some of the best tools that you can use to find LSI keywords.

LSI Graph

I do remember when I used LSIGraph for the first time, years ago. It was the first time when someone recommended researching LSI keywords.

I had no idea what LSI keywords do, and why it’s important to add relevant queries in the article. Although, my SEO coach had mentioned in the course. I didn’t pay attention because at that time Google was weighing backlinks too much.

It was too easy to buy PBNs from the market and rank.

Well, things change over time.

My rankings were gone in one Google Algo change, and I realized that something is missing.

Someone recommended adding LSI keywords in the articles.

I didn’t update the previous articles but added LSI keywords in the new ones. The first article with LSI keywords went to position 10 directly once published. It had never happened earlier.

I obtained keywords from LSIgraph.

That’s why I always recommend using LSIgraph because they are doing a great job in the industry.

But don’t rely completely on any tool. Your common sense also matters. The tool will provide you with so many keywords that you can’t add all of them. Some will be partially relevant and some will not be even close to query intent.

In that case, it’s up to you to pick the right keywords based on search intent.

Rank Math Content AI

Rank Math is a WordPress blog’s All-in-one ranking solution.

Rank Math is the pioneer SEO plugin offering this feature. They named it Rank Math Content AI.

I appreciate their approach.

Not all bloggers focus on so many things that help them rank higher. At least, no one does care about LSI Keywords.

Rank Math has offered a complete solution to rank faster on Google.

Rank Math Content AI tool provides you with relevant queries to add to the article and lets Google prioritize your content.

As it’s a new feature, and I believe they don’t have enough data so it’s comparatively less accurate than LSIgraph and Semrush.

Although, as they are offering keywords, questions, and external links to add to the article, that’s why it’s worth investing.

Google also notices whom you are pointing, and the anchors also matter. That’s why it’s a great idea to add external links to each article.

I never hesitate to add an external link if it’s necessary. Because article value is more important than link juice.


Semrush is another best tool that provides you with the best relevant queries to add to the article.

Semrush is surely doing a great job in the SEO tools industry. They focus on all the areas. No one else is focusing on so many areas.

Semrush is an easy-to-use and second-best tool to find LSI keywords.

Like LSIGraph, you put the keyword and it automatically provides you with the best relevant search terms.


Different people have different ways to find relevant search terms. One of my fellow bloggers is using Ahref to find relevant queries.

Though Ahref doesn’t offer LSI keywords in the tool you can use it to find out relevant search terms using Ahref.

Here is how to do it.

  • Put the keyword in Google
  • Pick the best performing results from SERP (from the first page only)
  • Put each URL in the site explorer
  • See for which terms the URLs are ranking
  • Pick all the best search terms from the data

The terms are your LSI keywords (not exactly).

Here is the other method.

  • Put the keyword in Keywords explorer
  • Pick the best keywords from suggestions, questions, and relevant results

The first method is good enough because you will get relevant queries that are already helping pages rank higher on Google.

And according to my fellow blogger, it works.

Example for the term LSI Keywords

It’s been a long I am not relying totally on tools.

It’s true that SEO tools lower the burden, and make things pretty easy to research. But tools might not be accurate all the time.

For instance, they don’t necessarily have up-to-date data. That’s why a manual Google search helps you even more than a tool, and it’s free.

Here is how I find my LSI keywords and you can too use the same method for free.

  1. Put the keyword in the Google (Open for the USA)
  2. Note down, “People also ask”
  3. Copy the “Related searches” given at the end
  4. Now again, type the main term in the google search box
  5. Autocomplete will suggest many search terms
  6. Pick the best from those autocomplete terms
  7. Make a single sheet for all the keywords and questions.
  8. Delete the terms that don’t make sense to the search intent.

You have got the best LSI keywords for your article.

It was all that you can use to find your LSI keywords and rank higher and faster on Google.
