What are LSI Keywords and How to Use These Keywords In Your Blog Post

A few years ago the Google used meta keyword to find the content relevancy. But bloggers started misusing it. They used to put a high density of keywords in their article. That’s why Google’s spiders confused and start showing worst results. But after researching Google introduced a new term LSI keywords that helped users to find relevant content.

LSI (Latent Semantic Indexing) keywords are the words & phrases that tell crawlers about the intent of the content. These are the synonyms or related words that you can use in your content in the place of a keyword.


It is a method to convince the search engine.

According to searchenginejournal.com LSI (latent semantic index) is a mathematical method used to recognize the terms and concepts in content.

Here you may notice that in the first definition I have written LSI keyword and in the second only LSI. It’s sound weird, isn’t it?

Let me make you clear why I do so because there is a little difference between LSI keyword & LSI. A latent semantic index is a method, but LSI keyword is a word or phrase used to increase post relevancy.

If your page includes some semantic keywords, the search engine understands that your content is very much related to your title tag and search query.

So, it is a good practice to include these phrases in your page to make it easily understandable for the search engine. LSI keywords help to limit the keyword stuffing.

Let me give you an example for better understanding

let’s take an Example of Apple.

If I ask you about Apple, you can not answer it because you don’t know the context of this query. You can either think about fruit or Apple iPhone. Eventually, you get confused due to the lack of semantic keywords.

But now if I ask you “what are the benefits of eating Apple“. Then You can answer it. Because here I have added the semantic words which increase the content relevancy.

It means if you are writing a post on topic “Apple”. Then you can include following terms and phrases in your post to increase your content relevancy.

Similarly, you can also enlist result for Apple iPhone.

From the above example, you can say that content relevancy is the most common factor to consider.

  • It helps search engines to recognize the context of content.
  • Reduces keyword stuffing.
  • It brings naturality in your content that increases readability.
  • Increase SEO score.
  • User & search engine can easily understand the context of your content.

How to find LSI keywords for your content

It’s time you found some words and phrases that act as semantic keywords and help you to increase content in-deepness.

You can find these keywords & phrases by using latent semantic indexing tools. There are many LSI tools that you may use for free.

#1. Google search

You can use this tool to find LSI keywords when you enter a query in Google search bar. It automatically shows you some related phrases that you can include in your article.

Now, let us see how to do it.

Let’s take the earlier example of “Apple“. Google search shows you following results.

As I have earlier described that distinguishing these keywords you need to use semantic words, For example, the keyword Apple is either used to define the mobile device or fruit.

So, to differentiate both the things you can include some additional words and make your keyword more sophisticated like LSI keyword.

If you are writing a post on Apple mobile, place semantic keywords like Apple iPhone, iPhone price in the US etc. You can also find some more results by scrolling down to bottom.

But if you are writing about Apple fruit, you can place these phrases given below.

Now, I am damn sure you become much familiar with the term Latent semantic indexing. But there is also a little confusion between LSI keyword & long tail keyword.

LSI are synonyms but long tail keywords indicate the length of keywords.

All the tools used to do keyword research also used as the latent semantic indexing tool.

How to insert LSI keywords inside your blog post

There is no exact way to use these word in your copy. But the best way that I realize is to write naturally. Because original copy writing automatically inserts similar words & phrase.

Nevertheless, there are many ways to include these phrases. You can use my technique.

First of all, you need to find a topic on which you are going to write.

Now, go ahead and start researching on that topic. Researching means read already published content on the internet related to your topic. After completing research, you will become comfortable & able to figure out in depth-ness of the context of copy.

Now, you know what your topic is all about. So, it is time prepared your title tag, focus keyword and start looking at the synonyms of that keyword.

For example, if you have picked keyword of Apple fruit you don’t need to put this absolute keyword again and again in your copy. Because it looks so wired using the same word unnaturally.

Instead of keyword stuffing include some relevant words & phrases that make sense. But the problem is where do you from grab synonyms.

It is pretty simple as I told you that before writing an article it is convenient to do research. Because it also helps you to understand the composition of copy. By researching, you can accumulate a list of LSI keywords.

For more LSI words collection you can use latent semantic indexing tool like Google keyword planner to find related terms.

Let’s see how you can perform it.

First of all, put your absolute keyword on the search panel and hit enter.

Here you find keyword matrices and also LSI keyword at the bottom.

These all are the semantic words that you can frame inside your article.

You can frame your post title, SEO description, headings & subheadings with the help of these words. Please, never over use these words in your copy, go naturally.

Here you have gotten a rough idea of framing. Now, it’s time to include these related words inside your paragraph.

I have written a paragraph on “apple fruit,” using proper LSI words. Let’s have a look.

Now, I believe that you have understood the Letant keyword framing process.


At the end of this lesson, I think that content formatting is the best part to create informative and relevant content.

From the above information, I have concluded that LSI is directly related to content relevancy and content relevancy is directly related to SEO.


LSI = content relevancy + SEO + search engine readability.
