Example shown — enter your own topic to plan a matching cluster.

How it works

  1. Enter your main topic.
  2. A pillar page title and a set of related subtopics are generated.
  3. Use the plan to structure your content calendar and internal links.

Planning suggests a broad pillar page title for your topic, then breaks it into narrower subtopics covering common angles — the pillar-and-cluster content structure that helps search engines understand a site's topical depth.

FAQ

Is my topic uploaded anywhere?

No. Planning happens entirely in your browser — nothing is sent to a server.

What is a topic cluster?

A pillar page covering a broad topic, linked to several narrower subtopic pages — a content architecture that helps search engines understand topical authority.

How are the subtopics chosen?

From common related angles on the main topic — strategy, how-to guides, templates, tactics, and measurement — the typical breakdown a pillar page cluster follows.

Can I edit the suggested subtopics?

Yes — add, remove, or rename any subtopic before using the plan to structure your content calendar.
