LSI (Latent Semantic Indexing) keywords are semantically related terms that search engines use to understand content depth and relevance. They are not just synonyms — they are words and phrases that naturally co-occur in high-quality content about a given topic. For example, LSI keywords for 'coffee' might include 'brewing methods', 'arabica beans', 'caffeine content', and 'espresso machine'.
LSI keywords improve SEO by signalling to search engines that your content comprehensively covers a topic. Pages that use related terms naturally rank higher because they demonstrate topical authority. They also help avoid keyword stuffing — instead of repeating one keyword, you use semantically related variations that improve readability and relevance scores.
Use 10-20 LSI keywords per page, woven naturally into your content. Don't force them in — they should appear organically in your headings, body text, image alt attributes, and meta descriptions. Focus on the terms that are most relevant to your specific angle on the topic rather than trying to include every possible related term.
