So, how do you incorporate LSI keywords in your SEO strategy to boost your rankings and attract desirable leads? Read on to find out.

What is Latent Semantic Indexing?

Before we delve into the nitty-gritty of LSI keywords, we must understand what ‘LSI’ actually means.

Latent Semantic Indexing (LSI), or Latent Semantic Analysis (LSA) is a Natural Language Processing (NLP) technique that was created in the ’80s to collect specific information from large groups of data. Computers use Singular Value Decomposition processes to identify contextual relationships between different terms in a given set of data.

In simple words, LSI helps search engines find the hidden relationship between different words in a document to improve information understanding. It allows computers to understand texts as humans do.

What are LSI Keywords?

LSI keywords are search terms that are semantically related to your primary (focus) keyword. They support your webpage by adding more context which makes it easier for search engines and users to understand what your content is about.

LSI keywords ARE NOT synonyms. These keywords are grouped together as they share the same context, not the same meaning. For instance, take the word “Tesla”. It can either refer to the company Tesla or the famous inventor Nikolas Tesla. Your search engine will look for different LSI keywords that are related to this term to understand your intent for this specific search.

If a webpage lists different inventions, accomplishments, & other inventors, your search engine will assume the webpage is about Nikolas Tesla.

On the other hand, if a webpage lists car models or other automobile companies, your search engine will assume the site is about the Tesla company.

The Key Benefits of LSI Driven Content

LSI would not be widely talked about within the SEO community if it didn’t provide a myriad of benefits. Integrating LSI keywords into your SEO strategy can provide the following advantages:

Let’s elaborate.

Higher Search Engine Rankings

Every search engine tries to provide its users with the results that they are seeking - relevant, helpful & valuable. Therefore, incorporating LSI keywords into your content will result in your search engine rankings rise for semantically related searches. The visibility of your website will increase.

Increased Content Credibility

LSI keywords will give your content proper context and will help search engines to identify and understand what your content is about. As your rankings increase & your content is shared further, the credibility of your webpage will grow.

Lower Bounce Rates

Bounce rate is the percentage of people who lose interest and click away from your website after visiting one page. If your content is LSI-driven, it will actively focus more on your target audience. Doing so would lead to more engagement and this would in turn result in lower bounce rates.

Better On-Site Browsing Time

Since your content is more cohesive and relevant, people will spend more time on your website. They are likely to click on the links you’ve provided on your site as well. Using LSI keywords makes your website feel more organized, which in turn greatly improves user experience.

LSI-driven content provides plenty more benefits. Ultimately, all of them result in a better user experience, increased lead conversions & better SEO.

Google and its relationship with LSI Keywords

Given how LSI works, it would be normal to assume that Google uses LSI techniques to understand synonyms and contextualize content throughout the board using its search engine.

However, the following tweet by Google analyst John Mueller proves otherwise. There are a few reasons LSI isn’t used by Google. Here is why.

LSI is from the 1980s

Some argue that LSI is old technology. It was created in the ’80s to before the world wide web was a thing. Therefore, it was never supposed to be used for an ever-growing amount of constantly changing data.

This is why Google developed a better word vector approach (RankBrain), which is more modern, scales better, and most importantly, works on the World Wide Web. Google also uses better Langauge Models. LSI was not created for the internet the way we know it today. Naturally, people came up with better alternatives.

LSI Technology is Patented

Bell Communications Reasearch, Inc. gained the patent to Latent Semantic Indexing in 1989. This patent expired in 2008. However, by that time Google had already developed better alternatives to LSI. Google search engines were adept at understanding search queries and providing relevant results way since at least 2003, so this goes to show that Google doesn’t really use LSI and hasn’t for a while.

LSI Was Not Created For The World Wide Web

The internet as we know it today is incredibly complex and expansive. Web pages in Google’s index change frequently regularly. The patented LSI developed by Susan Dumais states that there is an analysis run each time there is a significant update in storage files.

This would require a lot of processing power. Given that Google has come up with better alternatives, using this patented LSI technology would be an unnecessary expense.

All that being said, Google doesn’t use the LSI technology that was patented back in 1989. However, it does use semantically related words to contextually organize data and generate search results. Without a doubt, the content that is shown at the top of the Google SERPs have great topical authority & relevance.

How we phrase this methodology is up for debate (is this LSI or not?). But it’s evident that you need to conduct careful keyword research to help Google identify and understand what your content is about. In short, use semantically related words.

LSI Keywords In Paragraphs

Use your LSI keywords in your articles’ opening paragraphs & throughout your content in general. Add at least one LSI keyword in your conclusion. Moreover, use relevant topics as subheadings (H2, H3) and create paragraphs based on them. Lastly, remember to provide answers to your searchers’ questions in your article.

Optimize Images Used On Your Site

This follows the same principle as updating your old content by including LSI keywords. If you simply rename images on your site with LSI keywords, you will be able to optimize your site for SEO and benefit from increased exposure & visibility.

Parting Advice

Artificial Intelligence & machine learning technology has allowed search engines to progress rapidly over the past two decades. Google is the best example as it can now understand what web pages & topics are about, rather than being focused solely on target keywords.

LSI technology has become outdated and replaced and with it the practice of keyword stuffing. However, the significance of semantically related words & phrases has arguably increased.
