Latent Semantic Index

What role do LSI keywords play in SEO?

Latent Semantic Indexing (LSI) is an information retrieval system used to find hidden relationships between strings.

In search engine optimization, LSI uses keywords to create associations and links between words. LSI keywords are semantically related keywords or phrases that share the same context as the main keyword.

Online tools like the LSI Chart and Google Related Searches help you find LSI keywords.
