Hub-and-spoke linking is an internal link architecture in which a central pillar page — the hub — links out to multiple related sub-topic pages, and each sub-topic page links back to the hub. The structure mirrors the way topics and subtopics are naturally organised: the hub provides a comprehensive overview of a broad subject, while the spokes cover specific aspects in greater depth. This approach concentrates PageRank and topical relevance signals on the hub page, making it more likely to rank for competitive head terms, while the spoke pages target long-tail variations. The pattern became mainstream in content marketing circles around 2017 following HubSpot’s popularisation of the “topic cluster” framework, though the underlying linking principle had been recommended in technical SEO literature for many years prior.
