Topic Clustering
Definition
Topic clustering is an SEO and content strategy where a central pillar page covers a broad topic, supported by multiple cluster pages that address specific subtopics in depth. Internal links connect cluster pages to the pillar, signaling topical authority to search engines and AI systems. This structure is particularly effective for dominating AI Overviews and query fan-out.
Example
A pillar page on 'AI Marketing Strategy' links to cluster pages about competitive intelligence, content multiplication, multi-agent AI, and brand voice — creating a topical authority network.
