Topic Cluster

A group of related pages organized around one central topic, typically anchored by a pillar page and linked together.

How it demonstrates depth

Rather than one page trying to cover an entire subject, a topic cluster spreads coverage across multiple focused pages, each linking back to a central pillar — together demonstrating a level of coverage no single page could achieve alone.

Why it helps AI systems specifically

Consistent, interlinked coverage of a topic across a cluster gives a model more independent confirmation of the same facts, which can reinforce confidence in a brand's expertise on that subject.
