Hub and Spoke

Hub and spoke is a content structure built around one page covering a core concept in depth, the hub, linked to multiple pages each addressing a related sub-question, the spokes, giving both crawlers and readers a clear map of how a topic's pieces relate to the whole.

Why it matters

Hub and spoke is essentially the structural mechanism behind topical authority: without deliberate internal linking between a hub and its spokes, a site can publish comprehensive content on a topic and still fail to signal that comprehensiveness clearly to search or AI retrieval systems.

• Topical Authority

  Topical authority is how comprehensively a site covers a subject area, measured across content depth, breadth, and internal linking between related pages, rather than any single page's individual quality, making it a property of a site's overall content structure.

• Query Fan-Out

  Query fan-out is when an AI system decomposes one user query into several related sub-queries, retrieving source material for each before synthesizing them into a single answer, rather than treating the original question as one atomic search against one index.

• Information Gain

  Information gain is the unique value a piece of content adds beyond what's already publicly available on a topic, whether through original data, a distinct analytical angle, or details not covered by existing sources, rather than a restatement of consensus information.
