Organizing your content into topic clusters, built around one comprehensive page supported by several related ones, is a planning exercise you can do with a simple outline.
Choose a Broad Topic Worth a Dedicated Pillar
A genuinely central topic to your business, broad enough to have real depth underneath it, makes the strongest pillar page candidate.
Map Out the Related Subtopics Underneath It
Breaking the pillar topic into its natural subtopics gives you the outline for your supporting cluster content.
Plan the Internal Linking Between Them From the Start
Deciding in advance how cluster pages will link to the pillar and to each other keeps the structure intentional rather than accidental.
Next step: Use the SEO Audit to see whether your existing content already forms the beginnings of a cluster worth formalizing.
