Intro
LSI (Latent Semantic Indexing) keywords are often described as related keywords that help search engines understand content meaning. However, the concept of LSI keywords in SEO is a myth, as Google does not use LSI for ranking purposes.
Why the LSI Keywords Myth Exists:
- SEO tools often label related keywords as "LSI keywords."
- The term originates from an outdated indexing method (LSI) that Google does not use.
- Marketers assumed using synonyms and related words boosts rankings (which is only partially true).
The Truth About LSI Keywords in SEO
1. Google Does NOT Use Latent Semantic Indexing
- Google has confirmed that LSI is not part of its ranking algorithm.
- Instead, Google uses natural language processing (NLP), entity recognition, and machine learning to understand content relevance.
2. Semantic SEO & NLP Are Not the Same as LSI
- Google BERT & RankBrain focus on search intent, not LSI.
- Example:
- A page about "Apple" (the company) ranks based on its context (products like "iPhone," "MacBook") rather than LSI keywords.
3. Related Keywords Do Matter, But Not as "LSI Keywords"
- Google recognizes synonyms, variations, and contextual relevance.
- Example:
- Instead of focusing on "LSI keywords for SEO," optimize with contextually relevant terms like "search intent optimization," "semantic search factors," and "Google NLP."
4. Search Engines Use Entity Recognition, Not LSI
- Google’s Knowledge Graph & NLP algorithms connect entities and concepts, not LSI keywords.
- Example:
- "Tesla" is linked to "electric cars," "Elon Musk," and "EV charging," rather than a fixed list of "LSI keywords."
What Should You Focus on Instead of LSI Keywords?
✅ 1. Optimize for Search Intent & Semantic SEO
- Understand why users search for a query and provide relevant content.
✅ 2. Use NLP-Optimized Keywords & Contextual Relevance
- Write naturally, using related concepts, not forced synonyms.
✅ 3. Implement Entity-Based SEO
- Connect topics to recognized entities in Google’s Knowledge Graph.
✅ 4. Improve Internal Linking for Topical Authority
- Link related content to strengthen keyword relevance and content clusters.
Tools to Optimize SEO Without LSI Keywords
- Google Search Console – Monitor search queries and keyword performance.
- Ranktracker’s Keyword Finder – Identify contextually relevant terms and search intent.
- Ahrefs & SEMrush – Analyze related keyword variations and competitive rankings.
Conclusion: LSI Keywords Are a Myth – Focus on Semantic SEO
Google does not use LSI keywords for rankings, but it does prioritize semantic relationships, search intent, and NLP-driven content analysis. Instead of chasing "LSI keywords," focus on creating high-quality, semantically rich content that aligns with Google’s modern algorithms.
