What Is Latent Semantic Indexing?

To understand Latent Semantic Indexing, let’s start by looking at two important things that search engines do.

Search engines use complex algorithms to understand:

  • Content (what a page of content is about)
  • Search Intent (what people want to find when they search for a specific term)

Latent Semantic Indexing helps search engines accomplish these two tasks. It’s the part of the algorithm that identifies related words in content to better classify webpages and deliver more accurate search results.

By processing synonyms and understanding the relationship between words, the algorithm can interpret webpages more deeply and, therefore, deliver the right content to searchers.

LSI keywords are terms that are semantically related to the main keyword. A webpage with the main keyword “smartphones” may have the LSI keywords “iPhone,” “apps,” and “data package.”
