Topic Cluster
A Topic Cluster is a content strategy where a pillar page covers a broad topic, linked to several cluster pages that address specific subtopics. All content pieces are interconnected.
Why It Matters for GEO
Topic Clusters establish topical authority. AI engines recognize that a site with 10 interconnected articles on GEO is more expert than a site with 1 isolated article.
