What are LSI keywords and how do I use them in SEO?
Content
LSI (Latent Semantic Indexing) keywords are often misunderstood. Google does not use LSI technology directly, but semantic relevance matters. In 2025, SEO is about covering topics holistically, not stuffing synonyms. Instead of chasing “LSI keywords,” focus on semantic entities and related concepts.
Example: For a page about “electric cars,” related terms include “EV charging,” “battery range,” and “Tesla models.” Tools like Clearscope, Surfer SEO, and Google’s own NLP API help surface these.
Steps:
(1) Identify semantic entities with keyword tools.
(2) Map them to sections of your content.
(3) Use natural language—don’t force synonyms.
(4) Answer related questions (People Also Ask).
This improves topical authority, helping your site perform better in both traditional SERPs and AI search answers.
