Frequently asked questions

What is keyword clustering?

Keyword clustering groups semantically related keywords so you can target them with a single page instead of creating separate content for each keyword. This builds topical authority and prevents cannibalization.

How does the AI clustering work?

We expand your seed keywords using search data, then use AI to group them by topic and intent — not just by shared words. Each cluster gets a suggested page type like pillar page, blog post, or comparison page.

How many keywords can I cluster?

Enter up to 20 seed keywords separated by commas. The tool automatically expands them to related keywords before clustering. For larger keyword sets, use AltoRank's full keyword research suite.
