1 : What Is LSI Keywords?

Latent semantic indexing (LSI) keywords are essentially keywords that are semantically related to your main keyword, used in a search query. These LSI keywords supplement the main keywords to provide more substantial contextual information to the search engines and users. However, it is never intended to be the synonym of the said keyword or keywords similar in meaning.

In short, an LSI keyword is a keyword (or word phrases) that has a high degree of correlation (relevance) to the primary keyword.

LSI keywords of the main keyword "bakery".

Latent semantic indexing was originally developed as a mathematical method in the late 1980s for better information retrieval accuracy. The LSI technology is then widely implemented in various grading and analyzing text to uncover the text's meaning in response to user’s queries.

These accompanying words that provide context to the main keywords are what Google understands as LSI keywords. It generally helps to decide which is the correct meaning.

If Google is able to understand your content better, then you will have higher chances to rank better.

2 : Why Are LSI Keywords Important For SEO?

Understanding and implementing topical LSI keyword usage is critical today. Strategically integrating them into your content helps your SEO and provides your website with a competitive advantage.

Let’s look at its benefits and why they are such an essential aspect of your SEO today.

1

Helps Google algorithm determine the content quality and relevance to the search term

LSI keywords supplement stronger contextual information and meaning to a topic. Therefore, by including semantically related search phrases in your content, you give the search engines a better understanding of what your site is about.

Besides that, it also allows Google to improve the match between what people search for and what they find in the search results. Well true enough, the emergence of LSI was designed to help searchers get answers to what they're looking for.

More than ever before, topics build search engine results instead of just stuffing keywords. All the recognition provided on LSI keywords encourages website owners and their search engine optimization specialists to create and maintain quality content.

At the end of the day, your website visitors will be happy with what they see. Quality content keeps leads once they are in your funnel and hence increasing the conversion rate.

2

LSI keyword carries heavier weight than keyword density

Keyword density is the number of times your keyword occurs in your content and is measured in percentage. There was a time when all Google cared about was keyword density to rank a page. That goes to say, the more keywords you add in your content (whether relevant or not), the higher you will get ranked.

This method is infamously known as “keyword stuffing”. This black hat technique was quickly learned by marketers and misused not long after. Using repetitive keywords can put your page at risk of getting a penalty; but with LSI keywords, you can safely add closely related words without worrying.

Use LSI Keywords effectively by sprinkling them throughout your content and always make sure these keywords sound natural and make sense to the readers.

This is the perfect solution to avoid over-optimization of keywords too. We have all witnessed Google constantly enhancing its algorithm to identify and sort the most appropriate content for its users. Slowly but surely, the usage of LSI keywords has remained victorious until today!

3

LSI keyword empower other keywords in a content

When you create a new website or write an article, keywords play a prominent role in SEO . Just so you know, using all three classes of keywords (primary, secondary and tertiary) will help direct organic traffic to your website.

They also add more context to the keywords, making it easier to find results with higher relevancy. Google is avidly focusing on building relevancy between a category of keywords to a website rather than just a single keyword. Ideally, you will have higher chances to rank if your content includes other relevant terms than just repeating a long tail keyword.

In short, LSI keywords acts as a supplement to the primary, secondary and tertiary keywords used in a content. Implementing it helps in further strengthening the context and semantic relation of the content to its topic.

3 : How Can LSI Keywords Improve Your SERP Ranking?

Understanding LSI is now a requirement for modern SEO professionals and content marketers wishing to rank high in the SERP.

Ultimately, your SEO strategies need to mirror the sophistication of Google’s ever-changing search engine algorithm.

With that, here are three reasons how LSI keywords can improve your SERP rankings:

1

Google better understands the context of your page

Using LSI keywords gets searchers to the most relevant information and phrases that they are looking for. Similarly, it also helps Google to understand the context of the content better.

Since Google is constantly trying to provide its users with better search results and is focusing on the whole context of the page rather than just the density of the keywords, hence your page which is containing LSI keywords will get a better ranking because Google will be able to understand your page better now.

Let’s take "apple" as an example to illustrate. If words such as “healthy,” “sweet,” or “fruit salad” appears in the content, it’s safe to say that the word “apple” means the fruit.

On the other hand, if the following words contain phrases like “lightning port,” “iPhone,” or “gadgets,” it stands clear that “apple” in that context means the giant tech company.

To put it briefly, the proper usage of LSI keywords helps Google assign the correct search ranking. When you make Google’s job easier by including related keywords, you’ll see your rankings go up too!

LSI Keywords tell Google the right "Apple" users are searching for.

2

LSI Keywords helps you to understand user intent better

Understanding what users want is better known as user intent. It has become a driving force in SEO and search marketing to bring relevant people to your site. Since everyone searches differently or has a different goal in mind, using LSI keywords will benefit.

When you search for ‘warriors’ in LSIGraph, it will return with a list of LSI keywords. These keywords provide insights into what other questions people have in their minds when searching for ‘warriors’.

As a non-NBA fan, little did we know when people are looking for "warriors", they are looking for the NBA team.

From the results, we can see that when people type in "warriors", there is a possibility of including the American professional basketball team "Golden State Warriors" rather than the commonly known "warriors".

So, if you are planning to write a blog post on the basketball team “Warriors”, these are probably the things that you may want to talk about; golden state warriors, warriors schedule, golden state warriors score, and so on.

Knowing your user’s intent will aid you in doing keyword research accurately. As an online marketer, it’s our job to discover what our potential customers are searching for and provide them with the best answers possible.

3

Your page will appear on SERP for “keyword variations”

Since LSI keywords are closely related to your main keyword, this also means your page will come up in the search results for your main keyword and those keyword variations.

Keyword variations reveal the other popular searches of your main keyword.

By going through these variations, it shows you what other people are searching for too. Adding the related searches found at the bottom of the SERP makes your content LSI-friendly if you include them naturally in your content.

And there you have it, more relatable topics to scribble on!

5 : How To Use LSI Keywords Effectively?

Now, I’m sure you’ve already known the benefits of using LSI keywords, proceeded to try out the great LSIGraph tool, and got your best LSI keywords. So what’s next? You’d want to implement them in your content, so it reads well, right?

But where and how are you going to do that? Theoretically, you should sprinkle them throughout the body of your article, as long as it sounds natural and appropriate. Allow me to explain to you in detail.

Main places where you should include your LSI keywords

  • In headings

    A content’s headings (H1, H2, H3 tags) should contain keywords. Google pays special attention to the headers of pages that they crawl. LSI keywords may then help you decide how to break your content into smaller sections.

    Use LSI keywords in your content’s headings

  • In the link anchor text

    Texts that link to another location or document on the web are referred to as anchor text. For example, “LSIGraph generates unlimited LSI keywords for free”. LSIGraph (highlighted in blue) is the anchor text. You can include the keywords “LSI SEO,” “keyword tool,” and so on. It’s advisable to vary and diversify your anchor text as failing to do so will tell Google that you are forcing them in.

    LSIGraph generates unlimited LSI keywords for free. LSI Keyword is a keyword that is semantically related to the main keyword.

    Use LSI keywords in your content’s headings

  • In the alt text, file names, and titles of images

    When you upload an image online (in this case WordPress), you’ll see the alternate text like the screenshot below.

    The best practice for using alt text with an image is making it descriptive; don’t just stuff keywords in as Google will deem it an unnatural optimization.

    • In the page title to support your target keyword

      Use semantic keywords and craft a new title for your blog post. A good practice that you can emulate when writing page titles is to use your targeted SEO keywords or keyword phrases at the start of the page title. This ensures that your page title doesn’t get cut off in mobile SERPs if you include these essential phrases in front.

    • Use closely-related LSI keywords side by side (naturally) on the page

      Nobody wants to read keyword-stuffed content, right? It can be pretty hard to read the same word repeatedly. What you can do is to use your primary keyword within the first paragraph. Next, use your seed keyword and its variations throughout the content for best effects. Always remember to write for humans first.

      How many LSI Keywords should you use?

      You should use LSI keywords at designated places within the content of your article. But more doesn’t necessarily mean better. The question lies in: How many LSI keywords should you be using in your content?

      A good rule of thumb is to maintain a 2-to-1 ratio of LSI keywords to your main keywords. When using LSI keywords in your content, make sure that they are in the same paragraph of the keyword they are supporting, as this will help provide more context of your primary keyword to Google.

6 : Looking For A More Advanced LSI Keyword Tool?

Use LSIGraph Premium!

If you are using the premium version of LSIGraph, you will be unlocking all the essential metrics that are not available in the free version.

Let’s look at the results returned in the premium version with the same keyword that was previously used; “plumbing service.”

What you'll be getting on LSIGraph Premium

Based on the keyword “plumbing service”, the tool will generate a complete list of LSI keywords together with the data metrics such as trend, volume, CPC, Competition and Latent Semantic Value (LSV). These are important metrics that allow you to do your keyword research more accurately.

Latent Semantic Value is a measurement of how valuable the LSI keyword is in a context or topic. It is a value computed and formulated by our data analyst specialist who has experience in LSI keyword research and SERP competition.

The LSV value considers the keyword search volume, keyword competitiveness, and the keyword's traffic potential in a particular niche. The number ranges from 0 to 100, with 100 being the best and 0 the worst.

That means to say that the higher the LSV, the more valuable the keyword is. For instance, it is better to have keywords with an LSV score of 100 than those with 54.

In saying so, always consider the relevancy of your topic when choosing LSI keywords. A high LSV value keyword does not mean you should force it in your content if it does not fit well.

The rule of thumb is to choose LSI keywords with higher LSV scores closely related to your topic.
