What is
Topic Cluster?
A pillar page plus its supporting cluster pages — a coordinated set on one topic.
By Anish· Founder · Vedwix
·Definition
Topic clusters are the practical implementation of "topical authority." A pillar page targets the broad keyword; cluster pages target specific long-tail variations. All cluster pages link to the pillar, and the pillar links to many of them. Search engines reward this structure with stronger rankings on the pillar topic.
Example
A "AI Engineering" pillar with 30 cluster pages on RAG, fine-tuning, evals, agents, etc.
