Content-Cluster / Pillar Page

Definition

A content cluster is a strategic method in search engine optimization (SEO) and content marketing in which thematically related content is grouped around a central, comprehensive page—the pillar page. This structure helps search engines recognize a website’s topical relevance while also improving user navigation.
A pillar page covers a broad overarching topic and links to multiple cluster pages that explore individual subtopics in detail. Through internal linking between the pillar and cluster pages, a thematic network is created that strengthens authority within a subject area.

Examples of Measures

  • Selecting a clearly defined main topic for the pillar page
  • Creating multiple cluster pages for specific subtopics
  • Building a consistent internal linking structure
  • Defining a primary keyword for the pillar page and long-tail keywords for cluster pages
  • Using structured navigation elements for better orientation
