LSI Keywords
01 Definition
LSI Keywords meaning: A popular but technically inaccurate label for terms related in meaning to a main keyword.
LSI keywords, short for latent semantic indexing keywords, is a widely used SEO term for words related to your topic. The name borrows from an older document retrieval technique that Google has said it does not use. In practice, people use it to mean related or contextually relevant terms, which are still worth including.

Why it matters
How LSI Keywords fits the work
Whatever the label, covering meaning-related terms helps a page read as thorough and on topic, which supports its relevance for a broader range of searches.
In context
Writing about "cars," the author naturally included so called LSI keywords like "engine," "fuel economy," and "insurance" that fit the topic.
Practical note
The name is a misnomer, and no tool truly finds "LSI" terms. Ignore the theory and simply include natural, topically related vocabulary a reader would expect.
