What Are LSI Keywords?<\/h2>\n\n\n\n
LSI keywords, or latent semantic indexing keywords, refer to terms and phrases related to the main keyword or topic of a web page. These keywords are not synonyms in the traditional sense but are conceptually related to the main keyword.<\/p>\n\n\n\n
In SEO, we refer to this concept as “semantically related.” These are words that share a similar or connected meaning.<\/p>\n\n\n\n
For example, if the main keyword is “digital marketing,” some LSI (or semantic) keywords might include:<\/p>\n\n\n\n
- \n
- Social media marketing<\/li>\n\n\n\n
- Search engine optimization<\/li>\n\n\n\n
- Pay-per-click advertising<\/li>\n<\/ul>\n\n\n\n
They\u2019re not about the exact same thing, but they overlap in subject matter and theme<\/strong>.<\/p>\n\n\n\n
What Is Latent Semantic Indexing (LSI)?<\/h2>\n\n\n\n
Latent semantic indexing (LSI) is a technique that analyzes the relationships between words and concepts within a body of text. Unlike traditional keyword matching, which looks for exact matches, LSI goes deeper.<\/p>\n\n\n\n
- \n
- It examines how words connect within a broader context. <\/strong>For example, if the words “cat,” “feline,” “kitten,” and “claws” frequently appear together, LSI recognizes that these words are semantically related and contribute to the overall theme of “cats.”<\/li>\n\n\n\n
- LSI identifies underlying concepts and themes. <\/strong>By analyzing patterns in word usage, it can understand the deeper meaning and context of a piece of text, even if the exact keywords used are different.<\/li>\n<\/ul>\n\n\n\n
Essentially, LSI helps computers understand how words relate to each other and the broader concepts they represent.<\/p>\n\n\n\n
This allows for a more nuanced understanding of meaning and improved information retrieval.<\/p>\n\n\n\n
Does Google Care About LSI Keywords?<\/h2>\n\n\n\n
While the concept of LSI has influenced how search engines understand the meaning of content, it's important to note:<\/p>\n\n\n\n
Google does not use LSI keywords in its search algorithm.<\/strong><\/p>\n\n\n\n
Here\u2019s why:<\/p>\n\n\n\n
- \n
- LSI was developed in the 1980s<\/strong> as a technique for analyzing smaller datasets, not the massive scale of the entire World Wide Web.<\/li>\n\n\n\n
- Google's search algorithm has evolved significantly<\/strong> beyond simple keyword matching. It now uses sophisticated models to understand the nuances of human language, decipher search intent<\/a>, and provide the most relevant results.<\/li>\n<\/ul>\n\n\n\n
In 2019, John Mueller, a Google Search Advocate, definitively stated<\/a>, “There's no such thing as LSI keywords \u2013 anyone who's telling you otherwise is mistaken, sorry.”<\/p>\n\n\n\n
![\"John](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2025\/01\/john-mueller-lsi-keywords.jpg\" "\\"John")
<\/figure>\n\n\n\nThis statement underscores the fact that LSI keywords are irrelevant to modern search engine algorithms.<\/p>\n\n\n\n
So, no, Google does not care about them.<\/p>\n\n\n\n
With that said, related<\/strong> and semantic keywords are still very relevant<\/strong> in 2025. (Although many people still call these \u201cLSI keywords,\u201d which is technically incorrect.)<\/p>\n\n\n\n
You should also focus on:<\/p>\n\n\n\n
- \n
- Topic relevance: <\/strong>How closely does the page's content align with the user's search intent?<\/li>\n\n\n\n
- User experience<\/strong>: Is the content easy to read, well-structured, and informative? Does it provide a valuable and satisfying user experience?<\/li>\n\n\n\n
- E- E-A-T<\/strong> (Experience, Expertise, Authoritativeness, Trustworthiness<\/a>): Does the content come from a reliable source and demonstrate expertise on the topic?<\/li>\n<\/ul>\n\n\n\n
These factors better represent what Google prioritizes in content than LSI keywords.<\/p>\n\n\n\n
How to Find Related Keywords<\/h2>\n\n\n\n
So, if Google doesn't directly care about LSI keywords, are they completely useless?<\/p>\n\n\n\n
Not at all!<\/p>\n\n\n\n
The concept<\/em> of finding related keywords<\/a> is still highly valuable for SEO. Here\u2019s how to do it:<\/p>\n\n\n\n
First, you\u2019ll need a keyword research tool<\/a>.<\/p>\n\n\n\n
For our tutorial, I\u2019ll be using LowFruits<\/a>.<\/p>\n\n\n\n
![\"LowFruits](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2024\/10\/lowfruits-homepage-1024x554.jpg\" "\\"LowFruits")
<\/a><\/figure>\n\n\n\nLowFruits is the best SEO tool for finding related keywords for your content.<\/p>\n\n\n\n
It focuses on long-tail keywords<\/a>, which are keywords that typically consist of 3 or more words. These keywords have fewer competitors and higher conversion rates, making them extremely valuable for small business owners.<\/p>\n\n\n\n
To get started, we\u2019re going to navigate to the KWFinder<\/a>. You can locate this tool in the left menu.<\/p>\n\n\n\n
Then, enter a seed keyword<\/a> and click Search<\/strong>.<\/p>\n\n\n\n
![\"LowFruits](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2024\/10\/kwfinder-search-blank-1024x240.jpg\" "\\"LowFruits")
<\/figure>\n\n\n\nLowFruits will give you two options for viewing your report:<\/p>\n\n\n\n
- \n
- Access all keyword ideas. <\/strong>This option will give you a list of keywords, and you can pick which ones to analyze in SERPs.<\/li>\n\n\n\n
- Access all keyword ideas + analyze all high-intent keywords. <\/strong>This option analyzes all buyer intent keywords<\/a> automatically. You\u2019ll also get a list of all other keywords, minus the SERP analysis.<\/li>\n<\/ol>\n\n\n\n
![\"Options](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2024\/09\/high-intent-keywords-florist-1024x874.jpg\" "\\"View")
<\/figure>\n\n\n\nFor me, I typically pick the second option<\/strong>. It\u2019s faster and analyzes the higher-converting keywords. If you\u2019re low on credits, it\u2019s fine to pick the first option and analyze manually. (LowFruits uses a credit system to fetch keyword data from the SERPs.)<\/p>\n\n\n\n
From here, you\u2019re going to get a keyword report that looks like this:<\/p>\n\n\n\n
![\"LowFruits](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2024\/08\/los-angeles-florist-kw-report-1024x432.jpg\" "\\"LowFruits")
<\/figure>\n\n\n\nNow, we want to identify our main topics<\/strong> and find related keywords<\/strong> for each one.<\/p>\n\n\n\n
We\u2019ll use the Cluster<\/a> tool for this step.<\/p>\n\n\n\n
Click Clusters<\/strong> at the top of the page.<\/p>\n\n\n\n
![\"Clusters](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2024\/09\/keyword-clusters-lowfruits-1024x442.jpg\" "\\"Keyword")
<\/figure>\n\n\n\nThen, click the Semantic Clustering<\/strong> button. This will give us the semantic keywords we\u2019re looking for.<\/p>\n\n\n\n
![\"Semantic](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2025\/01\/semantic-keyword-clustering-1024x445.jpg\" "\\"Semantic")
<\/figure>\n\n\n\nLowFruits will ask you how many common words to use for keyword grouping. I like putting the setting as low as possible (2) to get the most results.<\/p>\n\n\n\n
![\"Semantic](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2025\/01\/semantic-cluster-settings-1024x493.jpg\" "\\"Semantic")
<\/figure>\n\n\n\nAfter a few seconds, you\u2019ll get a refreshed report that shows your semantic keyword clusters.<\/p>\n\n\n\n
![\"Semantic](\"https:\/\/blog.lowfruits.io\/wp-content\/uploads\/2025\/01\/semantic-keywords-florist-1024x416.jpg\" "\\"Semantic")
<\/figure>\n\n\n\nIn our example, we used the seed keyword \u201clos angeles florist\u201d for our keyword search. This query generated the following semantic keywords:<\/p>\n\n\n\n
- \n
- Los angeles florist district<\/li>\n\n\n\n
- Flower delivery la<\/li>\n\n\n\n
- How to become a florist in california<\/li>\n<\/ul>\n\n\n\n
As we discussed earlier, these keywords don\u2019t exactly match our initial search, nor do they have an identical search intent<\/a>.<\/p>\n\n\n\n
Instead, they\u2019re related to the main topic<\/strong> of an LA florist and fit naturally within the broader context of the subject.<\/p>\n\n\n\n
You can open any of these clusters to identify even more related keywords<\/strong> within each cluster.<\/p>\n\n\n\n

Finally, if you\u2019re a WordPress user, I highly recommend All in One SEO<\/a> (AIOSEO). This SEO plugin has a new Writing Assistant<\/a> that connects with your SEOBoost<\/a> account. It serves related keywords directly in the WordPress editor, making finding semantic keywords a breeze.<\/p>\n\n\n\n

<\/figure>\n\n\n\nHow to Use Related Keywords in Content<\/h2>\n\n\n\n
Now that you have a list of related keywords, how do you use them effectively?<\/p>\n\n\n\n
Here are a few tips for weaving them into your content:<\/p>\n\n\n\n
- \n
- Incorporate them organically. <\/strong>Seamlessly integrate related keywords throughout your content where they make the most sense. They should be a natural fit within the context of the page. You may include your semantic keywords in the introduction, subheadings, image alt text<\/a>, and throughout the body text.<\/li>\n\n\n\n
- Focus on search intent. <\/strong>Choose keywords that reflect a similar user intent. For example, if someone is searching for “how to bake bread,” related keywords might include “easy bread recipes,” “best flour for bread,” and “bread baking tips.”<\/li>\n\n\n\n
- Create high-quality content.<\/strong> The most important factor for Google is high-quality, informative, and engaging content. Focus on creating valuable content that satisfies user needs, and the relevant keywords will naturally follow.<\/li>\n<\/ul>\n\n\n\n
Final Thoughts<\/h2>\n\n\n\n
While the term “LSI keywords” might not be as relevant today as it once was, the underlying principle of understanding and leveraging related keywords remains indispensable for successful SEO.<\/p>\n\n\n\n
- \n
- Using related keywords can help you provide more comprehensive coverage of a topic.<\/strong> By addressing various aspects of your main topic, you create more in-depth and informative content for your audience.<\/li>\n\n\n\n
- Building authority in your niche.<\/strong> Using a broader range of relevant keywords demonstrates a deeper understanding of your subject. This helps establish your website as a credible source of information within your niche.<\/li>\n<\/ul>\n\n\n\n
Ultimately, this approach translates to a rich user experience, which can improve your online visibility and organic traffic.<\/p>\n\n\n\n
