TL;DR
- A topic cluster = one comprehensive hub page + 8-15 spoke pages, all interlinked.
- The hub targets the head term (“Amazon advertising”), spokes target long-tail queries (“how to reduce Amazon ACoS”, “Amazon Sponsored Display vs Brands”).
- Clusters outperform isolated pages 3-5x in organic traffic within 6 months.
- Internal linking pattern: every spoke links to the hub; the hub links to every spoke.
- AI engines reward cluster structure with higher citation confidence — they can verify claims by cross-referencing within the cluster.
What is a topic cluster (and why it works)
A topic cluster solves Google’s biggest signal problem: topical authority. Isolated blog posts on disconnected topics signal “this site dabbles in everything.” A tight cluster of 10+ pages on one topic signals “this site is THE authority on [topic].”
Hub-spoke structure:
HUB: /amazon-advertising-complete-guide
├── /blog/amazon-acos-too-high
├── /blog/tacos-vs-acos
├── /blog/amazon-sponsored-products-vs-brands-vs-display
├── /blog/amazon-ads-budget-india
├── /blog/amazon-ppc-mistakes
└── /blog/amazon-advertising-agency-indiaEach spoke targets one specific query. The hub aggregates them, providing context. Internal links flow both ways.
How to build a topic cluster in 6 weeks
Week 1: Define the topic. Audit your existing pages — keep what fits, retire what doesn’t.
Week 2: Write the hub page (3,000-5,000 words). Cover every subtopic at high level. Link to existing spokes; placeholder-link to spokes you’ll write.
Week 3-5: Write 8-12 spoke pages, one per subtopic. Each 1,500-2,000 words. Link each back to the hub.
Week 6: Cross-link spokes to each other where contextually relevant. Submit updated sitemap. Request indexing.
Cluster examples for Indian businesses
E-commerce/D2C:
- Hub: “D2C marketing in India 2026”
- Spokes: customer acquisition costs, Meta ads for D2C, WhatsApp marketing, Amazon vs own site, returns optimisation, etc.
Local services:
- Hub: “Belagavi digital marketing complete guide”
- Spokes: GBP optimisation, local SEO, Tier-2 Google Ads, Belagavi WhatsApp marketing, etc.
B2B SaaS:
- Hub: “Amazon advertising automation”
- Spokes: bid management, dayparting, search term automation, attribution, etc.
Common mistakes
- Thin spokes. A spoke under 1,000 words doesn’t earn cluster benefits.
- Inconsistent internal linking. If 3 of 10 spokes don’t link to the hub, the cluster signal weakens.
- Forgotten retirement. Old isolated posts on the same topic need to either join the cluster (with redirects) or be removed.
- Cannibalisation. Two spokes targeting the same query compete with each other. One must win.
Measuring cluster performance
| Metric | Before cluster | After (6 months) |
|---|---|---|
| Hub page sessions/mo | — | 5,000-15,000 |
| Spoke pages avg sessions | 100-500 | 1,000-3,000 |
| Branded queries | flat | +200-500% |
| Avg position for cluster terms | 8-15 | 1-5 |
FAQ
How many clusters can a site have?
Most agencies focus on 1-3 clusters per year. Quality compounds — better to have 2 dominant clusters than 10 weak ones.
Should every blog be part of a cluster?
Ideally yes. Standalone blogs rarely earn topical authority.
What if a topic doesn’t have 10 subtopics?
Pick a broader topic. If you can’t think of 10 subtopics, the cluster won’t sustain itself.
Do clusters help with AI Overviews?
Yes — significantly. AI engines cite cluster pages with higher confidence because cross-referenced facts are verifiable within the cluster.
Should the hub or the spokes target the head term?
Hub targets head term. Spokes target long-tails. Without exception.
