What are LSI keywords?

LSI (Latent Semantic Indexing) keywords are terms semantically related to your primary keyword. The original LSI math is from the 1980s and Google has moved beyond it, but the principle holds: pages that mention related concepts and entities rank better than pages that only repeat the primary keyword.

Does Google still use LSI?

Not literally — Google's John Mueller has confirmed Google doesn't use 1980s LSI algorithms. But Google does use semantic understanding (BERT, MUM, RankBrain) that achieves a similar effect: rewarding pages that demonstrate topical depth, not just keyword repetition.

How do I use LSI keywords without keyword stuffing?

Weave them naturally into headings, body paragraphs, image alt text, and FAQs. Don't cram them all in — pick 8-12 that genuinely belong in your article and let them appear where they read naturally.

Pick 8-12 to actually use. Don't cram in all 30+. Quality over quantity.
Spread them naturally. One in the title, a few in H2s, the rest in body paragraphs.
Use entities in alt text. Image alt text is a great place for entity-style LSI terms.
