Topic clusters
Content strategy that organizes pages around a central pillar page and related subtopics.
What is Topic clusters?
Topic clusters are a content organization strategy where a comprehensive "pillar" page covers a broad topic, while multiple "cluster" pages explore specific subtopics in depth. All cluster content links back to the pillar page and to each other.
This structure signals topical authority to search engines, improves internal linking, and helps users navigate related content. It's evolved from keyword-focused SEO to topic-focused SEO.
Why Topic clusters matters
Topic clusters establish topical authority, helping you rank for competitive terms. They create a logical site structure that search engines understand. Internal linking between cluster pages distributes ranking power effectively.
