Let’s cut at the heart of it:

  • The concept of latent semantic indexing (which the term LSI means) is an actual thing.
  • LSI keyword? It’s nothing more than an SEO legend…
  • Of course, you’ll be wondering: So why do you bother to write about LSI keywords?

Fair question. Here’s why:

It is essential to debunk the myths surrounding LSI terms to ensure they do not cause harm for SEOs who are just beginning their journey.

Although LSI keywords aren’t working, there are several legitimate ways to boost the quality of your articles by incorporating pertinent topics. Here’s a look.

Let’s begin at an early point…

What are LSI keywords?

The phrase LSI keywords can be utilized to refer to terms that are semantically connected to the primary keyword or topic.

Let’s assume that the subject of the post is weightlifting. That’s why the LSI keyword phrases include gym or exercise, weight reduction training routines, personal trainer Barbell, bench press, and so on.

This is the assumption:

  • If a website page contains similar words, synonyms, and key phrases used by other pages with high rankings in their text, it will get better rankings.
  • Therefore, you must locate these LSI terms and “sprinkle them” throughout your text, for Google recognizes that your site is pertinent.

Take note: If you’re a writer who freelances, there are likely to be customers who submit their writing documents with the list of (LSI) “keywords” and the synonyms for them that they’re expected to mention in the article for a specified amount of instances.

Let’s examine how this theory came to be and why it’s ineffective for researching keywords.

The Truth about LSI keyword phrases

Someone suggested LSI terms to Google’s Webmaster Trends Analyst John Mueller on Twitter, and John Mueller’s response was:

So Google’s very own specialist says LSI keywords aren’t authentic.

And then, there’s Bill Slawski (an expert on the subject of search engines and also one of the top brains of the SEO sector) who says:

They also claim that they’re not genuine.

However, if you conduct a Google search on “LSI keywords,” you’ll see more than a million results – the majority of which will provide you with information on what you can do with them to improve your SEO plan.

What’s the issue in this situation? Are they genuine, or is it not?

What is latent semantic indexing?

Latent semantic indexing (LSI) is a technique that is employed to obtain data from”latent semantic analysis (LSA), which has been in existence since the early 1980s.

It’s the kind that uses natural language processing, which establishes the relationships between documents and words which use these words.

We’ll not go over the intricate mathematical formulas that are used. Here’s an example to give you an understanding of how they appear at:

The method can be employed to serve a range of functions. However, it’s best to study (primarily static) database systems for enterprises.


  • Documents for classification
  • Eliminating the spam
  • Essay scoring
  • Summing up text
  • Visualizing information

Are you aware that the latent semantic indexing doesn’t do, or hasn’t been utilized for, however?

The Google search algorithm and indexing procedure (or the indexing process of any search engine, to be precise).

Does Google use LSI?

Google doesn’t employ search engine indexing that is latent.

It is because:

LSI is a dated technology.

Google isn’t required to employ the same process as LSI because it uses better algorithms that work with it. These algorithms prioritize high-quality, reliable content over less read-friendly ones and undermine visitors’ trust.

It is a question of why is it that so many people think Google makes use of LSI.

It’s difficult to determine the source of the LSI keywords phenomena. The cause is probably a mix of a variety of factors:

1. Some people get confused LSI with semantics

Many people believe that Google employs LSI and are actually saying that Google uses synonyms and semantically related terms.

There’s no proof to suggest that Google has ever utilized LSI. However, they’re pretty transparent about using natural language processing and attempting to figure out the meanings of the search results.

According to Google explained in their blog regarding how Google’s algorithm for search functions:

The synonym system helps Search determine what you’re talking about by establishing that different words refer to the same concept. This permits Search to find the answer “How to change a lightbulb” by providing pages on the steps to change a lightbulb.

This is a straightforward instance of how one word could have multiple definitions and how semantics aid in comprehending it:

  • And then, here’s an official explanation of the way Google indexes web pages:
  • If we index a page, we include it in the index entries for all its words.
  • According to Google’s terms, the indexed page is instantly added to search results for each word that appears on the page.
  • Perhaps someone thought of a link between this claim and how the LSI process operates.

The thought process could look something like the following:

  • “If I employ the right combination and frequency of these regularly occurring words from top-ranking posts, Google will automatically associate the quality and context of those sites with mine!”
  • But Google’s algorithm for searching is much more advanced than Google’s.
  • It is, at least for the moment. Is.

2. It could have worked in the past

Using keywords unnaturally to create a black-hat SEO strategy was an issue in the early 2000s.

It was back in the day when the algorithms of Google were not as advanced. It’s been a long time since when it was.

The primary risk with “LSI keywords” is that they’re highly similar to these outdated SEO methods:

Keyword stuffing

The goal is to achieve an optimum “keyword density.”

Be aware that neither one is working anymore and can harm your site’s ranking.

3. This sounds awesome

Clark Boyd summed up the “LSI phenomenon” in his essay about Search Engine Journal:

This name’s lure is in combining a science-based name with everyday use. This sounds as if it’s highly technological, but in reality, it boils down to using synonyms and related words and phrases, something anyone can accomplish.

It’s a trap that many SEO professionals have slipped into.

Do you have the ability to utilize LSI keywords to boost the ranking of your site?


At least, not in the way that it is usually explained by the authors of “how to use LSI keywords” articles.

The primary issue with the LSI keyword is that it places way too much emphasis on weaving specific phrases into websites in a way that is not natural.

Two critical points to be aware of:

If you’re focusing on crossing the words off of a keyword list or even using them for a specific amount of time, you’ll be compromising the authenticity of your content.

Your content is not written for Google to say, “Good job! It used all the same terms that the post with the highest rank uses!” This is not the way Google operates. There is no requirement to include all semantically related keywords.

The major problem with the theory that is behind the LSI keyword is the fact that it places way too much focus on the concept of weaving particular phrases into websites in a way that is not natural.

Then, what do you do?

Write and apply your expertise and experience to present the subject effectively.

Here are two suggestions for finding the most relevant keywords:

1. Utilize a keyword-based search tool

Utilizing keyword research tools is the easiest method to locate relevant keywords to a subject.

Did you recall the sentence “LSI keywords” for the term weightlifting in the beginning? Bodybuilding, gym, or weight loss…

They’ll be available as suggestions from every good Keyword research tool.

Here’s an example of KWFinder:

All you have to do is enter your primary search phrase and filter your results by the highest number of searches to get those with the highest popularity.

This doesn’t mean that you must utilize all of the keywords on the list of suggestions in your articles.

The reverse is true.

The primary benefit of using a tool to research keywords is that in addition to providing keywords suggested, it gives context and pertinent metrics.

Things you’ll learn such as:

  • How many people are searching for those keywords?
  • What is the difficulty of getting these keywords in the top search results?
  • What pages rank well with these terms at the location I want to target?

The final point, learning about your competition is crucial in the following step:

2. Do a competitor analysis

Analyzing competitors is an essential component of SEO.

This is more than simply analyzing the terms your competition is using.

The most important thing to do is look at the most popular pages that perform using your key phrase and then focus on factors such as:

  • What content types rank with the keywords?
  • What kind of structure do the best pages utilize?
  • How extensive are the blog posts?
  • What are the subtopics they will cover in their blog?
  • How far are they covering the subjects?
  • See? You don’t have LSI Keywords…

The idea is to look at “how to make the post as relevant as possible” and not “how to stuff the post with keywords so that Google thinks it is relevant.”

Imagine you’re planning to write an article about the difference between tea and coffee.

Look at the top-ranked blogs and see that they all contain the following:

  • caffeine content
  • health benefits
  • impact on the energy levels

It’s only natural you should also address these topics (some may refer to them as “LSI keywords”) in the article as they’re highly pertinent to your topic.

The outline you create is built on these subjects quickly.

The bad idea is to create a list of terms based on terms your competition is using (or which keywords the keyword tool advised you to select) and include all of them for your article.

The idea is to look at “how to make the post as relevant as possible” and not “how to stuff the post with keywords so that Google thinks it is relevant.”


LSI keywords have been a part of the SEO falsehood. While they don’t perform any optimization work, however, the concept behind looking for semantically relevant keywords will help you create better-written content.

In other words, there could be similar topics that you had not considered or imagined that people might be interested in the subject you’re discussing.

Ask you a few inquiries:

  • Did I take care to address all the central questions of my viewers?
  • Am I using the most widely used term to describe this issue/solution?
  • Did you find any related issues the competitor did not address, which would have made my site make a statement?
  • Be careful not to spend a lot of time doing this.
  • The standard method of keyword research will account for some of this.

If you’re attempting to understand an issue thoroughly, chances are you’re employing these phrases and terms. It’s a thing that occurs.
