How to Use LSI Keywords to Boost SEO Traffic?

Find LSI Keywords

To increase search engine results, SEO specialists employ a variety of approaches and strategies. While some of them are well-known, others are underutilised. Keywords based on Latent Semantic Indexing (LSI) come into the latter category.

Two key questions will arise for individuals who are unfamiliar with LSI Keywords:

  • What is Latent Semantic Indexing, and how does it work?
  • What are LSI Keywords, and how do you use them?

What is Latent Semantic Indexing?

What is Latent Semantic Indexing

Latent Semantic Indexing (LSI) is a computer method that was developed in the late 1980s to retrieve accurate information from big datasets. To detect the association between different words in an apparently random set of data, computers employ the Singular Value Decomposition procedure.

Is it a little too technical for you? Let’s keep things simple.

Search engines can use LSI to uncover hidden links between words in a document, allowing them to deduce the content’s true meaning. To put it another way, it allows computers to study and understand any text in the same way that people do.

What is the relationship between LSI and Search Engine Optimization (SEO)?

Search engines can understand your content and context, as well as your search intent and how it relates to a given keyword, thanks to LSI. Because search engines can read your content in the same way that humans can, employing relevant keywords will help it rank higher in search results.

Google is fully aware that understanding the context of any piece of material is becoming increasingly important. That is how latent semantic indexing became popular in SEO, and it is expected to continue to do so in the coming years.

What are LSI Keywords?

LSI keywords, according to the definition, are keywords that are semantically linked to your target (or focus) term. They are not, however, synonyms. Unfortunately, the majority of people believe that LSI keywords are synonyms. These keywords are grouped together because they are used in the same context yet have different literal meanings.

Take the word “Apple,” for example. It usually refers to a fruit or a well-known US technological company. To better understand the intent of your search query, a search engine like Google looks for different LSI keywords linked to this term. Here are two scenarios to consider:

  • If Google comes across words like pie, juice, milkshake, food, fruit, and farm, it will most likely assume the website is about an apple.
  • If Google comes across terms like iTunes, iPad, iPhone, Mac, Mac OS, MacBook, and iPod, it will most likely assume the website is about the smartphone and computer brand.

Similarly, when you type “Cooper,” Google will check for different LSI keywords to determine whether you’re looking for shoes (Lee Cooper), a car (Mini Cooper), or Sheldon Cooper, a fictional character from the American TV show The Big Bang Theory.
Let’s look at how Latent Semantic Indexing and LSI keywords can help you enhance your SEO rankings now that you know what they are.

Keyword Density

Keyword Density
Keyword Density

Keyword density was once one of the most important factors in determining a web page’s search ranking. In layman’s terms, keyword density is the ratio of the number of times a keyword or phrase appears on a web page to the total amount of words on the same page.

The keyword density of a page is stated to be 3 percent if a search phrase appears six times in a 200-word paragraph. It was used to see if a web page was related to a given search query. Web sites with a higher keyword density were naturally thought to be more related to the search term.

Unfortunately, keyword stuffing resulted as a result of this. Marketers could repeat emphasis keywords as many times as they wanted without regard for context. As a result, online sites frequently rank higher but offer no value to the reader.

With the development of powerful algorithms, search engines like Google no longer regard keyword density as a ranking criterion. Instead, they began focusing on a web page’s relevancy and context when ranking it. It also started penalizing web pages that used too many keywords.

A. Hummingbird and Rankbrain Duo

Google has begun to use two advanced algorithms, Hummingbird and Rankbrain, in recent years. The memory unit is the hummingbird. It creates an entity basis by listening to search queries and reading web pages and schema. That is why Google ranks entities rather than web pages.

Rankbrain is a type of artificial intelligence that determines the best match between search queries and Hummingbird’s nested entity database. It is capable of deciphering the search query and returning relevant search results. It maintains track of your search activity, likes, browsing duration, and online behaviour in order to create an educated judgement about your search intent.

B. Where Do LSI Keywords Fit In?

Google and other search engines would struggle to find a link between search phrases and the content on your site if you didn’t use LSI keywords. In other words, rather than repeating the focus keyword, use LSI keywords throughout the web page.

LSI keywords are not interchangeable, despite the fact that they have a similar meaning. As a result, you can utilise them more frequently without risking keyword stuffing penalties. They also enable you to develop conversational content that can interact directly with users. As a result, adopting LSI keywords benefits everyone, including customers, brands, and search engines.

The million-dollar question now is “How do I identify LSI keywords?” Finding LSI keywords is now easier than it has ever been. You might want to think about the following options:

A. Through Search Engine –

These are the keywords that Google associates with specific search terms. These keywords, however, will alter depending on your location and search query.

B. Google Keyword Research Tool

If you’re familiar with Google Keyword Planner, you can also utilise it. Otherwise, to utilise the Keyword Planner, you’ll need to create a Google AdWords account.

Go to the “Find Keywords” tab in your Google AdWords account. Select “Search for new keywords using a phrase, website, or category” from the drop-down menu. Hit the Get Ideas button after typing the same search word, “website.”

C. LSI Keywords Tools

The third method is to use one of the online LSI keyword generation programmes, which are either free or premium. One such tool is LSI graph, which allows you to search LSI keywords for up to 20 search queries per day. Simply insert your search word (we’ve used the term “website” again) and click the Generate button.

D. SEO Tools

LSI keyword research is the simple part. The difficulty lies in choosing the keywords with a decent amount of search volume and maximum relevance to your content. So, first, you need to understand why someone is searching for a specific item or information.

Next, you need to find keywords that are relevant and can be included naturally in the content. You may also find LSI keywords for a search phrase using SEO tools other than the Keyword Planner. For this, we frequently employ SEO tools such as Ahrefs and SEMRush.
For Ahrefs, you can use the Keywords Explorer’s “Search Suggestions” feature to find LSI keywords.

In the “Related Keywords” section of SEMRush, you can enter a keyword and search for LSI keywords.

The next step is to identify the most relevant LSI keywords for your content after you’ve found the keywords.

The easy part is finding LSI keywords. The challenge is determining which keywords have a reasonable degree of search volume and are most relevant to your content. So, first and foremost, you must comprehend why someone is looking for a specific item or piece of information. The next step is to locate keywords that are relevant and can be naturally included in the article.

A. Intent

Usually, a user intends to do one of the following three things –


People are interested in learning more about the topic at hand in this scenario. They’re primarily seeking generic information. People may wish to know what a website is and why you need one (going with our search term “website”).


This type of search query frequently indicates a specific direction. People may, for example, wish to know how to design a website with WordPress or which platform is best for e-commerce website development.


People utilise transactional purpose search keywords when they wish to complete a certain task, as the name implies. In this instance, it may be necessary to hire a web design firm.

B. Context

You’ll need to use LSI keywords that are extremely related to your content, of course. Then and only then will a search engine be able to index and rank your page in the SERPs (SERPs).

If you provide website design and development services to small businesses, for example, LSI keywords like “small business website design,” “budget business website builder,” “website development,” and “website hosting” are appropriate.

Is this to say you can use as many LSI keywords as you want? NO is the answer! Not all keywords will readily fit into the article. As a result, only utilise those that appear natural and meaningful.

Examine the text to check if everything flows naturally. Anything that doesn’t belong is to be removed.

Following that, you must avoid adding too many LSI keywords into your article. Avoid employing a single LSI term more frequently than others as a precaution. Make sure they’re evenly distributed throughout the content.
