What is Keyword Clustering?
Keyword clustering is an SEO technique that groups related keywords together based on semantic similarity, i.e., search intent.
For instance, the results that appear for the search query “shoes for women” can be the same as the results that appear for the key term “ladies shoe” or “female shoes.” Because people searching using both terms share the same intent.
