How Keyword Clustering Works

Our algorithm groups keywords that should target the same page

Word Overlap Analysis

Keywords sharing significant words get grouped together. "email marketing tools" and "best email marketing software" belong in the same cluster.

N-gram Similarity

We compare 2-word and 3-word phrases between keywords. Higher overlap means they answer the same search intent and should be on one page.

Intent Classification

Each cluster gets labeled as informational, commercial, transactional, or navigational based on the modifier patterns within the group.

Pillar Page Mapping

The shortest, most generic keyword becomes the suggested pillar. Supporting keywords become subtopics and internal link targets.

Frequently Asked Questions

About keyword clustering for SEO

What is keyword clustering?

Keyword clustering groups related keywords that should be targeted on a single page instead of creating separate pages for each keyword. This prevents keyword cannibalization (multiple pages competing for the same term) and builds topical authority.

Why not just create one page per keyword?

Creating separate pages for "email marketing tools", "best email marketing software", and "top email marketing platforms" causes cannibalization. Google splits your ranking power across 3 weak pages instead of 1 strong one. Clustering tells you these should be one comprehensive page.

How many keywords can I cluster?

Up to 500 keywords per session, completely free. No daily limits. For larger lists, split them into batches of 500 and cluster each batch separately.

What does the similarity slider do?

It controls how similar keywords must be to join the same cluster. "Loose" creates fewer, larger clusters (good for pillar pages). "Tight" creates more, smaller clusters (good for granular content mapping). "Normal" is recommended for most use cases.
