What are LSI Keywords? How to find & use in SEO

Uncover the impact of LSI keywords in SEO. Elevate content and context while improving search rankings with these vital semantic components.

Oct 14, 2023

Let me help you understand LSI in a better way today.

LSI has been going around the SEO industry for quite a long time.

Today we are going to talk about everything related to LSI keywords whether anything such exists, if yes then what it is?, How to find it? and how to use it?

What is the full form of LSI?

LSI full form is a Latent semantic indexing.

What are LSI Keywords?

LSI (Latent Semantic Indexing) Keywords are conceptually related terms, not synonyms or alternative words.

Based on LSI terms search engines like Google want to find the context of the topic and the quality of the content.

For example, if the topic is related to “Family Dentistry”, the search engine would expect to find words relating to that subject in the content of the page as well, i.e. “tooth”, “fillings”, “dentist”, “sedation”, "doctors", "treatments" and “patient”.

LSI has nothing to do with keyword stuffing or the frequency of keywords.

Does Google Use LSI in Their Algorithm?

Ummm... No

Yes, you read it right. Google has nothing like LSI Keywords. Here's the proof.

As stated by John Muller on Twitter in 2019, “There’s no such thing as LSI keywords – anyone who’s telling you otherwise is mistaken, sorry.”

Based on the tweet, Google is not using LSI. But, it does use other forms of semantic analysis to understand what your content is about.

This means, that using LSI keywords helps Google to understand your topic and content well.

⚠️ Technically not “LSI Keywords”: A lot of people within the field of SEO continue to use the term "adding LSI keywords" to describe the act of including related words and phrases on a webpage, even though this terminology is not strictly correct. We are going to follow the same term (LSI Keywords) in continuation of this discussion.

If not LSI then what does Google use

LSI is an old technology and is limited to finding results from smaller documents.

Considering the entire web, LSi is not the right fit.

But Yes, Google does care about semantics and it does it by:

Knowledge Graph:Google’sKnowledge Graphis a semantic network, that holds data regarding entities such as individuals and locations, as well as their interconnectedness.

Natural language processing (NLP):Google utilizes natural language processing (NLP) to recognize entities in both content and search queries, as well as to differentiate between nuanced differences in significance.

AI and machine learning: Google employs different artificial intelligence (AI) platforms to associate words with ideas, grasp the context, and assess the entirety of a text instead of just its individual components.

For example, "ahmedabad to mumbai flights " and "mumbai to ahmedabad flights" can look similar to algorithms but it's not that's what Google tries to recognise.

How LSI keywords are going to benefit SEO?

McDonald

Will Google be able to understand whether you are talking about McDonald's Cafe or McDonald Rhymes?

Yes, Google will be able to understand it.

HOW AND WHY?

Let’s discuss,

How will Google distinguish between McDonald Restaurant and McDonald Farm Rhymes?

If the “restaurant” word is on a web page, according to Google it should also include words like menus, food, price, and ingredients. Means all the words related to the restaurant.

If the “rhymes” word is on the web page, Google will look for words like kids, children, poems, school etc.

Google tries to collect semantic and related terms that are used along with primary keywords. If those keywords/terms exist in the content, it concludes that the topic is relevant to the keyword plus it can also understand the context and topic well.

Second example Apple

Here are you talking about Apple...Apple, the fruit or Apple the company.

Benefits of using LSI Keywords (related keywords and phrases)

  • Can understand the topic well
  • Can understand the content of the topic
  • It will keep your content looking organic
  • You will be able to incorporate multiple combinations of keywords
  • There are higher chances to match your topic with search intent

Based on the above few important factors about LSI, your search result will improve.

How to find LSI keywords?

Write Organically: If you are well versed with the topic on which you are writing, as per my experience you don't have to look around LSI keywords as you might incorporate those things by default.

Finding LSI keywords becomes essential only when you are writing on a topic you are not well aware of.

This is the point where many individuals who work as content writers and SEO professionals face difficulties. It becomes important for them to find semantic keywords along with the main keyword.

Well, it's simple sometimes still we always need to find the right way to do it.
