The professionals use various techniques and strategies which are to improve search engine rankings.

While most of them are common and the rest are highly underutilized. Latent Semantic Indexing (LSI) keywords are one of the techniques that are highly utilized.

There are many websites that are unaware of the best tactics and don’t know about two important things, Latent Semantic Indexing, and keywords. But do you really need them for your website?

Latent Semantic Indexing ( LSI ), keywords are considered a point of contention in SEO. It’s difficult to understand what they are and how they can help your website to rank higher on Google.

Earlier, it was seen that SEO methods were only for writing paragraphs of keyword-filled content and stuffing meta tags. This made latent semantic indexing (LSI) an extremely important approach for websites.

The professional link building makes proper use of LSI keywords.

They are search terms that are related to the main targeting keywords. They support your content to make it easier for both audience search engines to know what your content is about.

Today we’ll learn:

1. What Are LSI Keywords?
2. How Does Latent Semantic Indexing Algorithm Work?
3. Does Google use LSI?
4. How Did LSI Involve With SEO?
5. How To Find And Use Related Words And Phrases

So, let’s begin with the first topic.

What Are LSI Keywords?

LSI keywords are known as those words that are related to the main search keyword. They are seen as semantically relevant.

Let’s understand it with an example, if the user uses the keyword ‘credit cards,’ then LSI keywords would be like “money,” and “credit limit,”.

These words are not considered synonyms but they’re closely related words that help to define the topic of a webpage. The websites make use of semantically related words to get the web pages to rank on the SERPs. To make a successful website, you can’t ignore the importance of including these within your relevant local SEO.

According to the experts, Google has moved beyond indexing a page on the basis of single keywords. Now its algorithms use closely related keywords that are used in the context of the content. Earlier Google would look for references on a keyword to determine its relevance to the search query. So, if your webpage is about credit cards, then only these keywords were used to determine relevancy.

However, it is not an accurate way to determine the relevance of a page and this led gives rise to keyword stuffing. With the best SEO link building method, you can see how relevant content and keywords helps in indexing page.

With this obsession with keyword density, the evolution of the search engine understands how semantically related words help to define a topic.

Now, the time has changed and there is no need to use just a single keyword. Here, you need to understand why are keywords important. Using suitable keywords is important, and doing this helps to launch a page that comprehensively covers a topic is a key to success.

How Does Latent Semantic Indexing Algorithm Work?

The aim of Google is to provide its clients with the best information for what they are searching for. For this, it is important for Google to fully understand what information searchers are looking for and what keywords they are using.

With better information, Google indexes web pages to provide the best solution. Google follows the latent semantic indexing (LSI) algorithm which is developed to use the character strings in a document to establish their relevance to the search term used.

This works to establish the true meaning of the text on a web page.

The LSI algorithm looks at all the terms that are used in the text of a document to establish their true meaning according to the keywords employed.

This is why experts say to be specific when searching for information on Google. If your content has the word ‘Apache’ as a search term in Google, the top results will include things relevant to it.

It is not good to assume that Google will show up the same results for definition in the search term as you are thinking about. It is important to not only make use of your main keyword but define the definition of the word for your use.

If you use affordable Link Building Packages for your website, then you can increase the potential of your page or blog post to get listed for this search term.

1. Understand the Types of Intent

To make the best use of your LSI keywords, it is important to make search for primary keywords.

This is to be sure that keywords are good enough to get to your target audience and help Google to figure out the types of queries.

They can help Google to find your content. Below are different types of intent someone on Google might search for:

a)- Navigational: This is a specific type of query where the users want to know who invented it or what it’s made out of.

b)- Informational: This type of query is done on a broader scale which talks majorly about the working.

c)- Transactional: This type of query relates to purchasing something.

2. Context

The most important in LSI is to use the LSI keywords that are relevant to your content. With these relevant keywords, the search engine will be able to index and rank your page in SERP.

If you have a website design for small businesses then using LSI keywords such as “website development” and “website hosting” is the best choice. But that doesn’t mean adding as many relevant LSI keywords as possible.

Not all keywords will be able to fit into the content naturally. So, it is important to use words that seem natural and smooth with respect to content.

Adding too many relevant keywords will look like stuffing in the content. To make use of successful Link Building Strategies, it is important to scatter relevant keywords throughout the content evenly.

3. Character String Analysis

According to the expert’s guide to various types of SEO, a search engine algorithm does not use any dictionary but it involves a complex statistical and other analysis of the characters and strings. These strings are used in the text that makes up the entire web page.

It doesn’t matter whether it is a blog page, a post, a page on a website, or even a post comment, LSI can evaluate the whole content of any file present on the web.

To make the analysis more powerful, Google has introduced the best way to distinguish between language, vocabulary, and semantics.

Here you can see how these differ:

a)- Language: The language of the content becomes important as it is specific to a certain country or community. There are some words that have different meanings in different languages. Such as the text ‘pain’ means ‘bread’ in French, but that doesn’t mean to be in English. Google cannot tell you the difference unless it understands the language being used in the content.

b)- Vocabulary: They are the words used within a specific language. It is important to focus on it and to also refer to the range of words to use for a specific audience within a language. If Google considers it bad language, it is basically referred to as improper use of vocabulary words in the language. Let’s understand with a simple example, “box” is a word in English vocabulary which has several meanings leading to which box.

c)- Semantics: They are the same word that can be used to mention several things in different things. If you are using the word ‘box’ then it is considered semantics which refers to the meaning of words in a specific context.

d)- Syntax: It is called the way in which words are combined in a sentence. If you are typing the sentence ‘the dog bit the man’ can be expressed in the way ‘the man bit the dog.‘ Before LSI Google was unable to understand and distinguish the difference. According to researcher’s advanced link building tips, it is important to focus on the syntax of the content.

LSI takes each of these factors into account. If you really want to make your content the best fit to rank high in the search engines, focusing on keyword repetition is important along with a low keyword density (KD). This can provide you with better ranking results than a high KD.

The algorithm analyzes the proper meaning of the words along with semantics and syntax. It needs to get matched with the meaning of the keywords used by the person carrying out the search.

4. Meaning

The most important thing for your readers is to understand the meaning.

But what do you need to focus on Keywords or meaning?

If you are seeking information online on a search engine, this means you are offering to string your keyword and very few of the searchers can’t find your search term in the text. You know the answer to what the user is searching for and so does Google.

Google find, index, and rank only those web pages that contained keyword/phrase that is used by those seeking information.

The most important SEO tips for customers is to make online content contain the phrase keyword used within the search term several times, you may not be listed and be visible to anybody using that phrase.

5. No Ambiguity in Vocabulary

Google is aware of several keywords that can have different meanings in different aspects. It is important to take the character string that makes up the words and search for it within its indexed blog posts and web pages.

To know how LSI and keywords work it is important to know that search engines are smart enough to identify the context.

They can easily look at the content and synonyms related to your keywords. LSI keywords are also words that are frequently found together because they share the same context.

For example, “Apple” and “iTunes” is the best example of LSI keywords. Both keywords share the same context and are frequently found together but they are not synonyms. Right keywords help to bring quality links important for productive link building for SEO strategy.

6. Careful Regarding Keyword Stuffing

The important point to be considered is that there should be a requirement for long and excessive repetition of keywords.

Since LSI is introduced, it is important for all the websites to make sure that you prefer to use synonyms and related terminologies instead of using keywords several times.

It is also said that keywords still count but it is important to use only relevant keywords.

When you know what is link building, you get to understand how to provide website content and how to offer it to a large customer base.

It is all about the pages written specifically to get listed for individual keywords and useful content with relevant keywords makes it the best to get considered.

LSI is one of those factors that determine how well your content will rank on search engines.

To achieve excellent results and make your content lead to success, you need an effective SEO packages that consist of proper website architecture, backlinks, better optimizations, etc.

It’s definitely worth saying it takes some time to discover and add relevant LSI-driven keywords into your content. With the right keywords, your reader will be able to find the most relevant that is helpful information to meet their needs, faster.

Does Google Use LSI?

As LSI solves many problems, it is convenient to look at why people think Google utilizes LSI technology.

After all, it is obvious that matching actual queries is an inappropriate manner for search engines to return prominent documents.

But apart from this, Google almost certainly does not utilize LSI technology.

Now, you would say how do you know? Google representative claims that this helps to build links to website for your business.

Still doesn’t believe them?

Listed below are three main pieces of evidence to back up this fact:

1. LSI is a technology that was discovered way earlier

Latent Semantic Indexing was invented in the 1980s before the invention of the WWW (World Wide Web).

As such, it was never created for managing such a huge number of documents.

This is the reason why Google has since developed more scalable, better technology to solve the same issues.

Professionals say that LSI technology was not developed for anything like the size of the web. Google has created a word vector approach that is better, way more modern, and works on the internet.

2. LSI indexes known document collections

The WWW is not only huge but also ever-changing.

This clearly means that billions of pages in SERPs’ index change on a  daily basis to help you in the best organic link building.

This is an issue because the LSI patent declares that the analysis requires running every time there is an important update in the storage files.

3. LSI is known to be a Patented Technology

The LSI patent was given to Bell Communications Research, Inc. in 1989. Susan Dumais, who is one of the co-inventors who worked on the technology, later worked with Microsoft in 1997, where she worked on search-related innovations.

Given that Google was pretty good at understanding language and returning appropriate results way before 2008, this is very important evidence to recommend that Google does not use Latent Semantic Indexing.

Google does go for index synonyms and various other meanings for words. This can also be one of the popular tricks to increase domain authority. But it is not utilizing LSI technology to do that properly.

It would be like misleading people. Google has been providing synonym substitutions as well as query refinements focused solely on synonyms since at least 2003, but that does not mean that they are utilizing LSI. It is like saying that you are utilizing an effective telegraph device to link up to the mobile web.

How Did LSI Involve With SEO?

In its initial year, Google found that search engines were making websites rank according to the frequency of a specific keyword. This, however, does not assure the most appropriate search result.

Google rather than began ranking websites by considering valuable website ranking factor that is also considered trusted sources of information.

With time, Google’s algorithms would remove all the irrelevant sites with full accuracy.

Hence, marketers should know the meaning behind a search, rather than depending on the exact words being utilized.

This is the reason why people describe LSI as training wheels for search engines, also that is little to zero relevance to how search engines rank websites currently.

The clear meaning of a search query is related to the aim behind it. Google handles a document popularly known as Search Quality Evaluator Guidelines.

In this guideline, there are 4 beneficial categories for user intent:

✓ Know Query – This showcases searching for information regarding trendy content writing topics. An alternative to this is the ‘Know Simple’ query, which is when users are looking through a specific answer in mind.

✓ Do Query – This showcases the urge to get involved in certain activities, like a download or an online purchase. All of the queries can be defined by a hint of ‘interaction’.

✓ Website Query – This is when users are searching for a particular page or site. These searches show a prior awareness of a specific brand or website.

✓ Visit-in-Person Query – The user is looking for a physical location, like a mortar and brick store or say a restaurant.

✓ The theory behind LSI – Defining a word’s contextual meaning within a phrase- provide Google a great competitive edge. However, the concept of spreading LSI keywords is like a golden ticket to the success of a worthwhile SEO campaign.

If you understand a topic, you will naturally involve related phrases and keywords in your content.

For instance, it would be complicated to write about the best video games without highlighting words as well as phrases such as “Call of Duty”, and “PS4 games”.

But it is convenient to miss essential ones- specifically with more complicated topics.

Google probably considers these things as essential, semantically-related terms that any great content about the topic should mention.

That may be an aspect of the reason why articles that talk about these things steal your ranking.

Keeping this in mind, listed below are multiple ways to get profitable phrases, words, and entitles:

1. Use Common Sense

Find out your web pages to see if you have missed any obvious points. This is where you will observe the major need of SEO.

For instance, if the webpage is biographical content about Barack Obama and does not specify his impeachment, it is likely worth including a section regarding that.

2. Look At Autocomplete Results

Autocomplete results do not always show essential related keywords, but they can provide clues regarding ones that might be worth a mention.

For example, you can see “Barack Obama age”, “Barack Obama wife”, and “Barack Obama net worth” as autocomplete results for “Barack Obama”.

3. Look At Related Searches


Niched searches occur at the bottom of the search results.

Just like autocomplete results, they can provide ideas about potentially related phrases, words, and entities worth mentioning.

4. Use an “LSI keyword” tool

Famous Latent Semantic Indexing generators don’t have to do anything with LSI. However, they do kick back some great ideas that will help you attain the crucial advantages of SEO.

For example, if you search “Barack Obama” in a famous tool, it brings up some related people like Barack Obama’s wife and daughter.

5. Look At Other Keywords The Top Pages Rank For

Utilize the “Also rank for” keyword ideas analysis in any keyword explorer tool to get related phrases, words, and entities.

If there are many things to manage, try running a content gap analysis utilizing three top-ranking webpages, then fix the number of intersections to 3.

This represents the keyword that all of the pages rank for, which mostly provides you a more effective list of related phrases as well as words.

6. Run a TF*IDF Analysis

TF-IDF has nothing to do with LSI, but it can specifically assist to discover missing phrases, words, and entities.

7. Look At Knowledge Bases

Knowledge bases such as Wikipedia is a fabulous sources of related terms.

Google also brings out knowledge graph data from two knowledge bases.

8. Reverse-Engineer The Knowledge Graph

Google holds the relationships between many people, concepts, and things in something known as a knowledge graph. Results from the knowledge graph mostly pop out in Google search results.

Google search results for Barack Obama_Image


list of US Presidents result in Google_Image


Try finding out your keyword and look if any data from the knowledge graph shows up.

This is all because these are entities as well as data points that Google links with the topic, it is surely worth talking about a suitable one where it makes total sense.

9. Use Google’s Natural Language API To Find Entities

Paste the text in Google’s Natural Languages API demo. Search for appropriate and specifically important entities that you might have missed.

LSI was thought to be able to assist Google to match actual influential content writing with appropriate queries.

However, it looks like a debate in marketing surrounding the use of LSI has yet to reach a single conclusion. Apart from this, marketers can still take various steps to make sure their work remains strategically suitable.


The search engine uses LSI to find the context of any piece of content. It’s worth spending the time to know about the usage of these valuable keywords in your marketing campaigns.

Hence, to take full benefits of LSI keywords, businesses can hire a professional SEO company like Link building Corp.

The experts have vast experience in the SEO domain that can help you find the best LSI keywords for your content.
