Content Hub

What a content hub is

A content hub is a hub-and-spoke content structure: one broad "pillar" page covering a topic at a high level, surrounded by focused "spoke" pages that each go deep on a subtopic, all interlinked. The payoff is topical authority and cleaner internal linking — you show search engines you cover a subject thoroughly instead of publishing scattered one-offs that compete with each other.

People also call this a pillar-cluster or topic-cluster model. The names differ; the shape is the same. A hub that anchors the topic, spokes that answer specific questions, and links running both ways so authority and context flow through the group.

A real example

Take "email marketing." The hub is a broad guide at /email-marketing/ that maps the whole subject. The spokes are deep, specific pages: /email-marketing/subject-lines/, /email-marketing/segmentation/, /email-marketing/deliverability/, /email-marketing/automation/. Each spoke links up to the hub and back down, and the hub links out to every spoke.

The person searching "how to improve email deliverability" lands on the deep spoke and gets a real answer. The person searching "email marketing" gets the hub and a clear map of where to go next. Neither page tries to do the other's job, so they stop cannibalizing each other in the results.

Hub vs spoke: who does what

How to build a content hub

1. Pick a topic you can genuinely own. It should be broad enough for 6–15 real subtopics and close enough to your business that depth is worth it.
2. Map the spokes from real queries. Use keyword research and "People Also Ask" to list the distinct questions people ask. Each distinct intent is one spoke — don't split hairs into near-duplicate pages.
3. Define the hub's job. The pillar orients and routes; it summarizes each subtopic in a paragraph and links to the full spoke. It should not try to answer everything itself.
4. Write the spokes to actually resolve intent. Each one earns its place by being the best answer to its query, not by hitting a word count.
5. Wire the internal links deliberately. Hub links to all spokes; every spoke links back to the hub and to relevant siblings. Use descriptive anchor text, not "click here."
6. Prune and merge as you go. If two spokes target the same intent, combine them. A hub of overlapping thin pages is worse than a tight one.

Common mistakes and how to fix them

• Spokes that all target the same query. This is cannibalization wearing a strategy costume — your own pages fight for the same slot. Fix: one intent per spoke; merge duplicates.
• A hub that's just a link list. A bare table of contents doesn't rank for the head term. Fix: give the hub real explanatory content between the links.
• Forgetting the return links. Spokes that only get linked from the hub, never linking back or sideways, leave authority stranded. Fix: link up and across, every spoke.
• Padding spokes to look "authoritative." Bloating a 700-word answer to 2,500 words to seem thorough hurts the read and the rankings. Depth means covering the subtopic completely, not stretching it.
• Building the hub and walking away. Clusters decay as subtopics evolve. Fix: revisit, add spokes for new questions, and refresh the hub's summaries.

Frequently asked questions

Is a content hub the same as a pillar page?

The pillar page is the hub — the central broad page. "Content hub" usually refers to the whole structure: the pillar plus its cluster of spokes and the links binding them. So a pillar page is one component of a content hub.

How many spokes should a hub have?

Enough to cover the topic, no more. Six to fifteen is a common range, but the real answer is one spoke per distinct subtopic your audience actually searches. Padding the count with thin pages weakens the whole cluster.

Do content hubs need a specific URL structure?

It helps but isn't mandatory. A tidy /topic/subtopic/ path makes the hierarchy obvious to users and crawlers, but the internal linking — not the URL — is what actually defines the cluster.

Will a content hub rank on its own?

Structure alone doesn't rank — it amplifies quality. If the individual pages aren't genuinely useful, a neat hub-and-spoke diagram won't save them. The architecture multiplies good content; it doesn't manufacture it.

What's the difference between a content hub and just having a blog?

A blog is a chronological pile of posts that often compete and rarely interlink on purpose. A content hub is deliberately organized around one topic with a clear pillar and intentional links, so the pages reinforce each other instead of scattering.

Where this fits

A hub is only as strong as the pages in it — each spoke should aim to be the best answer available, which is the bar 10x content sets. For the architecture in depth, see topic clusters and pillar pages: strategic implementation and the pillar page definition. To wire it up correctly, work through the internal linking strategy for topic clusters.
