What is Topic Clusters?
A content strategy organizing pages around central topics with supporting subtopics.
Understanding Topic Clusters
Topic clusters organize your content into groups centered around a pillar page that covers a broad topic comprehensively, with multiple cluster pages that dive deep into specific subtopics. All cluster pages link back to the pillar and to each other where relevant. This structure signals to search engines that your site has deep expertise on the topic, strengthens internal linking, and helps users navigate related content easily. The model has largely replaced the old approach of creating isolated pages targeting individual keywords.
Why It Matters
Topic clusters build topical authority, which is increasingly important as search engines evaluate expertise across your entire site rather than page by page. Sites with well-organized topic clusters tend to rank higher across all keywords within that topic.

Frequently Asked Questions
How many cluster pages should a topic cluster have?
A strong topic cluster typically has 5-20 cluster pages depending on the breadth of the topic. Focus on covering every meaningful subtopic rather than hitting a specific number. Each cluster page should target a distinct keyword with unique search intent.
What makes a good pillar page?
A good pillar page comprehensively covers the broad topic at a high level, provides clear sections that link to deeper cluster content, and serves as a reference hub. It should be long-form, regularly updated, and structured with clear headings that match common subtopic searches.
