Hub and Spoke

In a hub-and-spoke architecture, the hub page is a comprehensive overview of a broad subject — it introduces the topic, covers its major dimensions, and links to every spoke. Each spoke is a dedicated, deep-dive article on a specific subtopic. Spokes link back to the hub and, where relevant, to sibling spokes.

The model is a structural implementation of topical authority. The hub functions as an authority center that both signals topical ownership and distributes link equity to its spokes. The spokes rank for specific long-tail queries and funnel authority back to the hub. The system compounds: each new spoke added increases the hub's topical authority, which raises the ranking potential of the entire cluster.

Hub-and-spoke architecture is identifiable during due diligence as a deliberate SEO investment. Its presence indicates that whoever built the site understood topical authority and structured content accordingly — which predicts that the site's rankings are more structural and defensible than those of a flat content site.

A wellness site with a hub page titled 'Complete Guide to Magnesium' that links to 15 spoke articles covering topics like 'magnesium glycinate vs citrate', 'magnesium for sleep', 'magnesium deficiency symptoms', 'best food sources of magnesium', and 'magnesium and blood pressure' — with each spoke linking back to the guide and to two or three related spokes — is a textbook hub-and-spoke cluster.

The hub page does not need to be the longest page on the site — it needs to be the clearest, most navigable entry point into the subject. A hub that is genuinely useful as an overview, and that contextually links to the most relevant spoke for each subtopic it mentions, performs better than one that is artificially padded to hit a word count target.
