The question
When a topic warrants a pillar-and-cluster structure.
You are deciding whether to invest in a pillar page for a topic.
Why it matters
Pillar pages are powerful but only when backed by a real cluster and tied to business value.
How to decide
IfThe topic is broad, valuable and you can build a full cluster
ThenYes - build the pillar and its spokes together.
IfYou cannot resource the supporting cluster
ThenNo - a pillar with no spokes under-performs.
IfA pillar already exists but lacks spokes
ThenComplete the cluster before adding new pillars.
