Introduction: What Are LSI Keywords?
LSI Keywords, short for Latent Semantic Indexing keywords, are words or phrases that are semantically related to your main keyword. They help search engines understand the context of your content, which can improve visibility and ranking in search engine result pages (SERPs).
Contrary to common belief, Google does not officially use LSI technology anymore, but the term is widely used in SEO to mean contextually relevant keywords that support your primary keyword.
For example:
- Primary Keyword: Digital Marketing
- LSI Keywords: SEO, email marketing, PPC, online advertising, content strategy

How to Find LSI Keywords
Finding LSI keywords is easier than you might think. Here are a few effective methods:
1. Use Google’s Search Suggestions
Start typing your main keyword into Google’s search bar. The autocomplete suggestions are often contextually related to your topic.
For example, typing “healthy recipes” might suggest:
- healthy recipes for weight loss
- healthy recipes vegetarian
- easy healthy meals
2. Look at Google’s “People Also Ask”
This section shows questions that are semantically tied to your search query. These make excellent additions to your blog’s subheadings or FAQs.
3. Analyze the “Related Searches” Section
At the bottom of Google’s results page, you’ll see related search terms. These are perfect for finding LSI keyword variations.
4. Use SEO Tools (More on this below)
Tools like LSIGraph, KeySearch, and Semrush can give you a refined list of related terms.

How to Use Latent Semantic Indexing Keywords
Simply finding LSI keyword isn’t enough—you must also use them wisely to avoid keyword stuffing and maintain content quality. Here’s how:
1. Naturally Integrate Them in Your Content
Sprinkle them throughout your article—especially in:
- Subheadings (H2, H3)
- Intro and conclusion
- Paragraphs explaining your topic
- FAQs or bullet points
2. Include in Metadata
Use LSI keyword in your:
- Meta descriptions
- Image alt tags
- Title tags (only if natural)
3. Use Them in Anchor Text
When internally linking other content, use LSI keyword as anchor text. For example:
“Learn more about content planning tools to enhance your digital marketing efforts.”
4. Write for Context, Not Just Keywords
Make sure your content answers user intent fully. If you’re writing about “SEO tools,” including terms like “keyword research,” “backlink analysis,” and “site audits” helps Google better understand your topic.
5. Improve Topical Authority
Using semantically related keywords signals depth. It shows search engines your content covers a broad scope, improving relevance and trustworthiness.
