Which SEO Cluster Structure Should You Use?
| Business Type | Recommended Structure | Key Internal Linking Strategy |
|---|---|---|
| Educational website | Hub-and-spoke | The pillar introduces SEO and links to detailed guides. Each guide links back to the pillar and to related guides when useful. |
| Large real estate portal | Hierarchical / Multi-level | Use clear parent-child navigation and breadcrumbs. Helps users navigate from broad categories to specific property types and guides. |
| Digital marketing agency | Silo structure | Keep related content grouped within each subject section. Cross-link between silos only when the connection is useful (e.g. Ads landing page to conversion tracking). |
| Dental clinic or service provider | Service-based | Each service page targets commercial intent and links to supporting educational content. Supporting articles link to relevant service pages. |
| SaaS or software help centre | Problem–solution | Organize content around problems customers want to solve. Link tutorials to relevant software features and related help articles. |
| Restaurant chain or local business | Location-based | Each location page should have accurate branch-specific details (address, hours, menu, directions). Never create location pages for branches that do not exist. |
| Training company serving different audiences | Audience-based | Tailor content to each segment's needs, level of knowledge, and goals. Link each audience page to the courses or services most relevant to that segment. |
| Furniture or fashion ecommerce | Ecommerce category | Category pages link to subcategories and products. Buying guides link to relevant collections. Manage faceted navigation and filter URLs carefully. |
