Topic Cluster
A hub page on a broad subject, surrounded by narrower pages that each answer one part of it, all tied together by internal links.
Analogy Mental model
A solar system. The sun is the head term, the planets are the subtopics, and gravity is the internal linking that keeps them in orbit instead of drifting apart.
In practice What you actually do
One long guide sets the vocabulary and takes the broad query. Twenty shorter pieces each take one specific question and link back to the guide, which links out to all of them. The shape is what signals coverage of a field rather than coverage of a page.
Where people get burned Pitfalls
The failure mode is overlap. If two cluster pages answer the same question, neither becomes the obvious destination, and the hub ends up linking to two half-answers where one good one would have won.
