LSI or Latent Semantic Indexing keywords are the keywords semantically associated with the keyword entered by the users in any search engine.
Example:
If a search engine discovers a page with the word ‘Apple’, then how will it identify if Apple is a brand or fruit? The search engine will now use LSI keywords. If it will find words fruit, flavour, or taste in the article then it would be easy for the search engine to determine that the article is all about the ‘Apple fruit’. Thus, fruit, flavor, or taste are the keywords for the keyword ‘Apple’.
