What is LSI ?

[SEONinja]

LSI or Latent Semantic Indexing works on the premise, that words in an article that are used in the same way, like synonyms, mean one thing and is therefore, relevant to each other. For example, in writing an article for weight loss where I target the keywords "lose stomach fat", I can only use the target keyword a certain number of times. So, I will use the synonyms or variations of the target keyword, and this helps increase the relevance of your article to your target keyword.
