Keyword optimization is crucial to improving the organic traffic of a site.

However, with the numerous Google algorithm updates, optimizing a website for SEO doesn’t cut it. Online marketers have to keep up with the changes and adjust their content accordingly.

One such algorithm is the need for sites to use Latent Semantic Indexing instead of long-tail keywords. The Hummingbird Update of 2013 was introduced to eliminate the use of single keywords to make it easy for search engines to provide relevant search results to users.

Google later changed its search methods by introducing Latent Semantic Indexing (LSI) keywords. The text elaborates on the subject and how SEO experts can use the tool to enhance organic traffic.


What is Latent Semantic Indexing?

It is an algorithm that enables search engines to understand the context on the web page, make an accurate comparison with other search results and match it with the user’s query. This way search engines use more detailed information that helps them to relate context and language.

The algorithm evaluates the semantic relationship between documents using vectors, cosine similarities, and other complex mathematical relations. As such, semantic relationships are classified in two ways:

  • Semantically close relations: it occurs when documents have many similar words
  • Semantically distant relations: In this case, documents have a few related words

Google determines if the documents are semantically close or distant by analyzing patterns in the context. The patterns can be in the form of similarities and synonyms, phrase correlations and associations, or the number of synonyms used.

The algorithm calculates similarity features based on the patterns, assigns a value to the document and displays search results that match the user’s query.



Why Use Latent Semantic Indexing Keywords
