Topic cluster
Example shown — enter your own topic to plan a matching cluster.
How it works
- Enter your main topic.
- A pillar page title and a set of related subtopics are generated.
- 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.
