Many business blogs are a random collection of posts. Google can’t see a clear area of expertise, and readers don’t move from articles to services. Topic clusters fix this by organising content around your core services.
What is a topic cluster?
A topic cluster has:
• A pillar page: a comprehensive page on a core topic, often a main service page or a complete guide
• Cluster content: related articles that cover specific subtopics in depth
• Internal links: every cluster article links to the pillar, and the pillar links to the cluster articles
Example cluster: SEO services
Role | Page |
Pillar | SEO Services in Coimbatore (service page) |
Cluster | SEO pricing in Coimbatore |
Cluster | Local SEO checklist |
Cluster | Google Business Profile guide |
Cluster | SEO for doctors and clinics |
Cluster | How long does SEO take? |
Cluster | SEO report template |
Why clusters work
• Show Google you cover a topic thoroughly
• Help Google understand how pages relate
• Pass internal link authority to your most important pages
• Guide readers from questions to services
• Make content planning easier
How to build your clusters
1. List your core services (three to six usually).
2. Choose or create a pillar page for each, usually the service page.
3. List the questions customers ask about each service.
4. Group questions into cluster articles.
5. Write cluster articles that answer each question fully.
6. Link every article to its pillar with descriptive link text, and link related articles to each other.
7. Update the pillar to link to the best cluster articles.
Cluster ideas for common businesses
• Web development: website cost, redesign signs, WordPress vs custom, landing pages, maintenance
• Clinics: treatment pages as pillars; FAQs, recovery guides and cost articles as clusters
• Real estate: location pillars; area guides, buying guides and project updates as clusters
Common mistakes
• Cluster articles that don’t link to the pillar
• Several articles targeting the same keyword
• Pillars that are too thin to deserve links
• Clusters unrelated to services you sell
