What is Topic Clusters?

Topic clusters represent a modern approach to content organization that aligns with how search engines understand topical expertise. Instead of scattered individual posts, content is structured around central "pillar" pages supported by related "cluster" content, all linked together to demonstrate comprehensive topic coverage.

A topic cluster consists of: Pillar Page - comprehensive overview of a broad topic, Cluster Content - detailed articles on specific subtopics, Internal Links - connections between pillar and cluster pages. This structure signals topical authority and helps search engines understand content relationships.

Topic clusters improve SEO through: Demonstrating topical expertise to search engines, Distributing link equity efficiently, Improving crawlability and indexation, Creating logical user journeys, Building authority faster than scattered content, and Reducing keyword cannibalization.

Create effective clusters by: Identifying core topics aligned with business goals, Mapping subtopics through keyword research, Creating comprehensive pillar content first, Developing focused cluster articles, Implementing strategic internal linking, and Updating content as topics evolve.

Real-world applications: "SEO" pillar with clusters on technical SEO, link building, content optimization. "Email Marketing" pillar with clusters on automation, list building, segmentation. "Photography" pillar with clusters on lighting, composition, editing. Each cluster should be 5-15+ related pieces.
