What is Content Cluster?
A content cluster is a set of pages on one subject, linked to each other and to a central hub page. The hub covers the topic broadly. The spokes go deep on single questions. Links run both ways. Done properly, the cluster tells Google which page you want ranking for the head term and passes strength between the pieces rather than splitting it.
Linked Topic Group
How the hub and spokes fit together
Pick one subject you want to own. Write a hub page that covers it at a level a newcomer understands, then add eight to twenty supporting pages, each answering one narrow question the hub only touched on. Every spoke links up. The hub links down to each spoke, and spokes link sideways wherever the connection is genuine rather than manufactured to hit a link count.
The internal linking is the whole mechanism, because it concentrates signals on the hub, makes the relationship between pages explicit to a crawler, and gives a reader somewhere sensible to go next instead of dead-ending on a narrow post. Without it you have a folder of posts. Nothing more.
Keyword mapping matters here. One primary query per page, no overlap, and if two spokes are both chasing ‘property management charges Gurugram’ you merge them before either goes live rather than after they start fighting each other.
Common ways clusters fall apart
Building the spokes and never finishing the hub happens constantly, because supporting posts are easier to write, so they go live one by one while the hub sits in a Google Doc for four months and nothing connects to anything. Write the hub first. Even if it is rough. Improve it as the spokes land.
Another failure: linking with generic anchor text. Twelve internal links all reading ‘click here’ tell Google nothing about what sits on the other side, and they waste the one ranking signal you control completely.
Then there is scope creep, where a cluster on Shopify store setup drifts into general marketing advice, picks up three posts about Meta ads, and stops being a cluster at all. Keep a written scope line. Reject anything outside it. Ruthlessly.
What this looks like in practice
An e-commerce brand selling home textiles builds a cluster around fabric care. Hub page: caring for cotton and linen at home. Spokes: washing in hard water, drying through the Delhi monsoon, storing quilts over summer, removing common stains, and what GSM actually means when a listing quotes it. Each spoke pulls a small but genuinely interested audience, and the hub collects the strength.
Commercially this works because the cluster catches people well before they are shopping, so a WhatsApp enquiry option and one soft product link on each spoke will convert at a rate a cold product page never reaches.

Content Cluster — questions, answered.
A hub plus eight to twenty spokes is a workable range. Fewer than six rarely produces enough internal linking to matter. Build in batches of four or five so the cluster stays coherent instead of sprawling in every direction at once.
Ideally yes. Orphan posts that link nowhere and sit outside any theme tend to underperform badly, whatever their quality. If a post idea does not fit an existing cluster, either start a new one deliberately or drop the idea.
