Keyword Clustering

What is Keyword Clustering?

Keyword clustering is a process of grouping similar keywords together based on their meaning or intent. This is done to improve search engine optimization (SEO) by targeting related keywords with the same content.

When you cluster keywords, you are essentially creating a "topic cluster." This is a group of pages on your website that all focus on the same topic.

Types of Keyword Clustering

There are two types of keyword clustering:

  1. Morphological-based keyword clustering is a process of grouping keywords together based on their morphological similarity. This means that keywords are grouped together if they share the same root word or stem.
  2. SERP-based keyword clustering is a process of grouping all the keywords together based on their similarity in search queries. This means that keywords are grouped together if they appear on the same or similar pages in search results.

Here are some details about each type of keyword clustering to improve your search volume.

Morphological-based keyword clusteringMore accurateCan identify keywords that are not as popularMore time-consumingDifficult to implement
SERP-based keyword clusteringFaster and easier to implementCan identify keywords that are often used togetherLess accurateCan be influenced by factors other than the meaning of words

If you're not sure which type of keyword groups to use, it is a good idea to try both and see which works best.
