What is LSI? - Accuranker

LSI stands for Latent Semantic Indexing. This is a concept used by search engines to find the hidden (latent) relationships between words (semantics) to improve understanding (indexing). LSI explains how search engines can understand that a search term and web content can mean the same thing, even if they don’t use the same words. Rather than matching search queries exactly to words on a page, search engines use complex calculations to identify context and synonyms.
