page title icon Everything About LSI keywords in SEO with Examples

No one can deny the important role of keyword research in blogging. Keyword research is a crucial part of writing content. It involves thinking about a word or phrase that you want to rank by finding a low difficulty level with an average monthly search volume.

But in the SEOs world, there is a flood of myth that has been circulating for years and changing the scenario of SEO. Some myths like Google Sandbox have been already discussed in our blog to clarify that there is no such term in Google’s data.

LSI (Latent Semantic Indexing) helps in SEO ranking is another myth that is continuously spreading its legs over the Internet by brainwashing the newbies in SEO terms.

Many SEOs experts claim that using LSI keywords can positively affect your ranking and increase your content visibility and ranking but that’s not 100% true. Google does not use LSI in SEO to boost ranking.

Let’s know what LSI Keywords are in SEO and Does they really help to boost your ranking?

Before understanding its concept let me help you to know what SEO experts define about LSI keywords.

What are LSI keywords in SEO

Definition of LSI keywords in SEO

LSI (Latent Semantic Indexing) also referred to as LSA (Latent Semantic Analysis) is a term in which Search Engines like Google, Bing and other engines web crawlers find a word that is similar to the keyword in your content or you can also say synonym of the keyword in your content.

These keywords help to increase your site ranking and visibility for Search Engines and ultimately helps you to increase traffic and boost your site authority.

By using LSI keywords in your content, you can primarily avoid the blackhat technique “Keyword Stuffing.” It also acts as a helper for your main keyword and pushes forward your ranking in SERPs.

Example of using LSI Keywords in SEO

To use semantic keywords, not everyone really needs any examples. but to help the beginners in their SEO journey, I’d like to mention some with proper and actual examples of LSI aka Latent Semantic Keywords.

For example, if you have written content about “yogurt” but to avoid keyword stuffing and using LSI keywords, you can use “Curd.”

To also rank in India, you can use the Dahi keyword. So, the term Yogurt, Curd and Dahi is the name of the same product which is prepared by Daily Product. Since yogurt is prepared with bacterial enactment but it is similar to Curd.

Another example, people searching for “opticals” can also suggest seeing “glass” as these are the synonyms of one single product.

However, Glass is a polysemic word that means a single word or phrase that has more than one meaning. As glass can be also a normal glass or it can be also an optical.

You can also use the polysemic word in your content because the Google algorithm i.e. BERT (Bidirectional Encoder Representations from Transformers) is quite smart to understand your content.

Some time back there is lit on Twitter about LSI. Many of the bloggers engage in discussions about SMITH (Siamese Multi-depth Transformer-based Hierarchical) Algorithm that is smart enough to understand your whole content same like human do and can replace BERT Algorithm in future.

Well, that will be no use in discussing this now to spread myth facts about anything that is clearly not mentioned from Google itself. When this algorithm will come to life, it is still not confirmed yet.

However, the above definition of LSI keywords is not accurate. Let’s know the history of LSI (Latent Semantic Keywords)

History of Latent Semantic Indexing (a.k.a LSI) Keywords 

LSI is a technology that is old from the discovery of the internet. The patent for LSI was registered on 15th September 1988. Yes, it’s that much old.

That year, it was used to understand the text matching meaning.

It was old for over 30+ years.

The actual reason that SEOs experts consider that Google uses Semantic keywords to increase and boost ranking is that in the year 2003, Google acquired the company called “Applied Semantic.”

Applied Semantic has formulated a technology that was named as “Circa”. This algorithm is used in Google Adword and Google Analytics.

The statement released by Google’s Press also says this.

Google’s co-founder and president of Technology, Sergey Brin said:

Applied Semantics is an authentic innovator in semantic text processing and online advertising. This accession will enable Google to create new technologies that will make online advertising more useful to users, publishers, and advertisers.

The SEO myth that has been circulating since the 2000s that Google used Latent Semantic Indexing for SEO purposes, has been spread like it actually exists.

But in reality, Google purchased Applied Semantic Companies to serve ads using Latent Semantic Indexing.

I hope, from now, you really don’t believe any terms that even do not exist but followed by almost 90% of bloggers.

Does using LSI keywords really helps in SEO

LSI keywords in SEO

LSI keywords in SEO are basically synonyms of your main focus keyword. However, you will be glad by reading this that yes, LSI, to some extent, helps in ranking though it is not officially stated in Google Webmaster policy or any other place but Google’s AI is smart enough to understand the clarity of your sentence and the words you have used in your content and also the tone of your article.

Basically, Google uses the BERT algorithm to understand the meaning of the content.

Whenever you write any content about any topic, Google’s AI reads and recognises the specific and relevant LSI keywords that you have used in your content and thus helps your content to rank better in Search Engines and ultimately it helps in SEO to some extent.


Do not get confused about LSI keywords in SEO. It is not officially stated anywhere that it really boosts ranking by helping in Search Engine Optimisation.

Let me say once again to those who focus on LSI keywords in their article.

“There is no such thing called LSI keywords in SEO consider by Google”

It will be better if you focus on the quality of your content rather than on Latent Semantic Keywords.

Note: Google’s AI used LSI (Latent Semantic Keywords) to serve an ad based on your content. It does not have any SEO relevance.

There are even many myths that exist in SEO and are believed by most of the people. One of them is Google Sandbox. Make sure you do not believe anything that you read over other blogs. This is because not everyone shares the actual facts and instead they copy from other bloggers and then write about the same.

Some advice to get better ranking and get visibility in SERPs:

  • Create a stunning and qualitative content that can be termed as 10X Content
  • Know about Link-Building and make some quality backlinks for your website
  • Use optimized WordPress Theme for your site
  • And last but not the least, Focus on the quality of the content rather than the quantity

I hope you have understood the meaning of LSI in SEO and how it works. Use synonyms in your content to avoid keyword stuffing and make your content readable and understandable.
