In the world of digital marketing, keywords have been the backbone of SEO (Search Engine Optimisation), which helps search engines understand the focus of the webpage and connect users to relevant content. The use of keywords, traditionally alone, is no longer sufficient in today’s online competitive landscape. This is where Latent Semantic Indexing (LSI) keywords come into play. This enhances both content relevance and search engine performance. What Are LSI Keywords?  LSI or Latent Semantic Indexing are phrases and terms which are semantically related to a primary keyword. They are closely connected but not exact synonyms in terms of meaning and context.
