A topic cluster groups a broad pillar page with several detailed supporting articles, all linked together. It shows search engines that you cover a subject in depth, not just one keyword.
This structure also makes it easier for visitors to find what they need.
Choose your core topics
Pick the subjects most important to your business and your customers. Each becomes a pillar page that gives a complete overview and points to deeper content.
Write the supporting articles
Create articles that answer specific questions within each topic. Link every supporting article to the pillar and to related pieces with descriptive anchor text.
Maintain the cluster
Review performance, update outdated pieces and fill gaps in coverage. Over time the cluster strengthens the rankings of every page within it.
