Keyword Clustering

Keyword Insights vs. Semrush

Both tools have keyword clustering modules, but which is right for you?

How Keyword Clustering Works?

Keyword clustering involves grouping keywords that are similar to each other together. Essentially a “keyword cluster” is a group of keywords that mean the same topically and can be targeted together on a single page.

Upload your keyword list into Keyword Insights, and we’ll analyse the search engine result pages to group any keywords together where the ranking URLs are the same or similar.
