LSI keywords

Have you ever heard of the term LSI keywords? How about just LSI? In 2019, John Mueller of Google said, ‘There’s no such thing as LSI keywords.’ Then how come so many people in the SEO community use it?

What are these elusive LSI keywords? And why should you even bother? Let’s put it this way: Whatever they’ll turn out to be, it’s important to understand their real purpose in search engine optimization and writing.

Intrigued? Buckle up because we’re about to embark on a journey to demystify LSI Keywords and transform your SEO game. Ready to dig in?

What are LSI Keywords?

LSI keywords are words or phrases related to your main keyword and are considered basic elements for search engine optimization.

These keywords are also referred to as related keywords. They provide context to your web pages, helping search engines understand what your content is about.

Think of your main keyword as the lead actor in a movie. LSI Keywords? They’re the supporting cast, vital for the storyline, adding depth and context to your web pages.

For example, if your main keyword is “apple,” LSI keywords or related keywords could be “fruit,” “orchard,” “pie,” or “iPhone,” depending on the context of your content.

If your content is about fruit, search engines would expect to find LSI keywords like “fruit” and “orchard.” If it’s about technology, they would expect to see words like “iPhone.”

What does LSI mean?

LSI, or Latent Semantic Indexing, sometimes also referred to as latent semantic analysis, is a mathematical method used by search engines to classify, organize, and retrieve data from web pages based on the specific keywords and ideas that can be found within them.

In simple terms, LSI, or latent semantic analysis, is a process of retrieving information from a piece of content on the web to understand its context.

The Confusion with LSI Keywords

In the SEO community, there has been confusion with the use of the term ‘LSI keywords’ and what LSI really is. Taking away from the definition of the concept above, latent semantic indexing is a term used to call a process of retrieving information.

What LSI is not is a term used to classify a keyword. This is why the term ‘LSI keywords’ is technically considered inaccurate. We cannot use the term LSI to classify a keyword like we would describe ‘long-tail keywords’ and ‘seed keywords.’

Basically, LSI is a process, not a term used to classify keywords. In this context, it’s more proper to refer to them as related keywords.

However, while the term “LSI Keywords” might be technically inaccurate, the concept of using related words and phrases in content to provide context and enhance relevance remains crucial.

Google’s focus is on understanding content topics based on the entirety of the content, not just specific keywords.

Therefore, while “LSI keywords” as a term might not be the right phrasing, the practice of using semantically related words to enhance content relevance is still vital for SEO.

Now that we’ve got that all cleared, for the sake of this blog’s topic, let’s just continue to use the term ‘LSI keywords’ to refer to keywords, or related words and phrases, that help clarify a content’s context.

5 Reasons to Take LSI Keywords Seriously

Latent Semantic Indexing (LSI) keywords have evolved as a significant component in the realm of SEO. These keywords not only enhance the contextuality of content but also play a pivotal role in improving search visibility.

Let’s delve into the reasons why incorporating LSI keywords into your content strategy can be a game-changer.

1. Enhanced Search Visibility

Incorporating LSI or related keywords into your web pages amplifies its contextuality, making it more relevant to a search engine. This relevance ensures that your content stands out, leading to improved search visibility.

As search engines evolve, they prioritize context over mere keyword repetition. Hence, LSI keywords serve as a bridge to ensure your content aligns with this evolving priority.

2. Better Content Contextualization

LSI keywords provide a broader context to your content. Instead of focusing solely on one target keyword, semantically related words offer a more comprehensive understanding of the topic.

This depth ensures that both users and search engines grasp the essence of your content, enhancing user experience and search engine rankings simultaneously.

3. Avoidance of Keyword Stuffing

Overloading content with primary keywords can lead to penalties from search engines. It is considered a black hat-approach to increasing keyword density. LSI keywords offer a solution by allowing diversification in keyword usage.

By sprinkling related words throughout your content, you maintain keyword relevance without over-repetition, ensuring your content remains organic and penalty-free to Google and other search engines.

4. Improved User Experience

LSI keywords contribute to a better search experience for users. By incorporating semantically related words, your content becomes more aligned with user intent, leading to increased time spent on the page, reduced bounce rates, and enhanced user satisfaction.

In the long run, a satisfied user base can translate into higher conversions and brand loyalty.

5. Staying Ahead in SEO Evolution

The world of SEO is ever-evolving, with search engines continuously updating their algorithms. LSI keywords have become an integral part of these algorithms, ensuring content remains contextually relevant.

By integrating LSI keywords, you ensure your content remains in tandem with SEO trends, securing its position in search results.

In SEO, staying updated with best practices is crucial. Semantically related words, with their emphasis on context and relevance, have emerged as indispensable tools in this journey.

By understanding and leveraging their potential, you can ensure your content remains user-centric and search engine-friendly, paving the way for sustained online success.

How to Find and Use LSI Keywords in 3 Ways

Uncovering the right LSI keywords can significantly boost your SEO strategy. But where can you start finding LSI keywords? And how can we make this kind of keyword research plain and easy?

Here are three practical LSI keyword research methods that utilize Google’s built-in features to help you discover and effectively use LSI keywords in your content.

1. Google’s Autocomplete

Google’s Autocomplete is a handy tool to find LSI keywords. As you start entering your search queries, Google automatically suggests a list of possible completions that are based on popular searches by other people.

These suggestions can serve as LSI keywords as they provide insight into what users are frequently searching for related to your primary keyword.

TIP: Make sure to take note of all the suggestions Google provides, even if they don’t seem directly related to your primary keyword. The goal here is to broaden the context of your content, and these suggestions can help you do that.


How to use Google Autocomplete:

  1. Type in your seed keyword onto Google’s search bar.
  2. Then, watch as Google drops down its autocompleted suggestions of all the other popular searches related to your seed keyword. You can use these suggestions as inspiration for your keyword ideas.
  3. Take note of the words in bold. These can serve as your LSI keywords.

2. ‘More to Ask’ Section

The ‘More to Ask’ section in Google Search is another valuable source of LSI keywords. This section pops up when you use a search engine and displays a list of related questions other users have asked that are related to your search.

These related questions can be used as LSI keywords since they are relevant to your primary keyword and provide additional context.

TIP: Don’t ignore the ‘More to Ask’ section, even if the questions seem unrelated to your main topic. Remember, LSI keywords offer a broader perspective, and these questions can help you understand the various angles users are interested in.

How to use the ‘More to Ask’ section:

  1. After searching for something on Google, scroll down until you reach a section that looks like the image above.
  2. Click the drop-down arrows to reveal sneak peeks of how other websites write about/answer the question beside the arrow.
  3. If you want more questions, click the drop-down arrows on other questions. Every time you click an arrow, more questions are added below for you to check out.

3. More Searches

The ‘More Searches’ or ‘Related Searches’ section at the bottom of Google Search results is another excellent spot to find LSI keywords. This section provides a list of searches that are related to your primary keyword, giving you more context and ideas.

TIP: Be sure to check out the ‘More Searches’ section for every primary keyword you use. This can provide you with additional LSI keywords that may not have appeared in the Autocomplete or ‘More to Ask’ sections.

How to make use of the ‘More Searches’ section:

  • This section works quite similarly to Google’s autocomplete suggestions. Observe how some of the words in the boxes in this section are bold. These words in bold, or the entire search term, are suggestions you can use as LSI keywords.
  • It’s more effective to list these keywords down somewhere. As you write your content, you can sprinkle these short-tail and long-tail keywords where necessary in your content.

Common Mistakes to Avoid When Using LSI Keywords

Latent Semantic Indexing (LSI) keywords are words or phrases that are closely related to your main keyword. They add context to your content, helping search engines understand it better.

However, there are some common mistakes people often make when using LSI keywords. Here’s what to avoid:

  1. Using Unrelated LSI Keywords: One of the biggest misconceptions is that any synonym or related term can be used as an LSI keyword. This is not true. LSI keywords should be contextually relevant to your main keyword and the overall content. Using unrelated terms can confuse search engines and lead to poor SEO performance.
  2. Overusing LSI Keywords: Another common mistake is overusing LSI keywords. Just like primary keywords, LSI keywords should also be used sparingly. Overuse can lead to keyword stuffing, which search engines penalize.
  3. Ignoring User Intent: LSI keywords should align with what users are searching for. Ignoring user intent and focusing solely on search engines is a mistake. Always consider what your audience wants to know and use LSI keywords that match their queries.
  4. Not Updating LSI Keywords: SEO is a dynamic field, and what works today might not work tomorrow. It’s a mistake to use the same LSI keywords without updating them. Regularly check for new related terms and update your content accordingly.

Keep your LSI keywords relevant and use them naturally in your content to avoid these mistakes. Always consider user intent and regularly update your keywords.

Remember, the goal of LSI keywords is to enhance the understanding of your content, not to confuse search engines or users.

In Summary

LSI Keywords, or Latent Semantic Indexing keywords, are closely related words or phrases to your main keyword, providing context and helping search engines understand your content better.

Missteps in using them, like using unrelated terms, overusing, ignoring user intent, or not regularly updating them, can lead to poor SEO performance. Tools such as Keysearch’s LSI Keywords Generator, LSIGraph, and Serpstat can aid in finding these keywords.

These platforms are user-friendly and come with a range of pricing options. Don’t miss out on the ‘Related Searches’ section on Google, as it can provide additional LSI keywords that can turn your content into a popular post.

Consider giving these techniques and tools a try to optimize your content for better visibility on search engines.
