Pillar Page / Cluster Content

Definition

Pillar page / cluster content refers to a central content format in content marketing and search engine optimization (SEO), in which a main page (pillar page) comprehensively presents a broad core topic and uses internal links to specialized subpages (cluster content). This pillar-cluster model strengthens topical relevance, improves user navigation, and enhances search engine visibility.

A pillar page is a detailed, structured main page that covers a topic area holistically but only touches on individual aspects. In-depth information is provided by linked cluster pages, each addressing a specific subtopic and linking back to the pillar page. The overall system—a central main page with a network of specialized subpages—is referred to as a topic cluster.

  • Creating a central pillar page on a core topic (e.g., “Digital Marketing”)
  • Producing multiple cluster pages on subtopics (e.g., “SEO,” “Social Media Marketing,” “Content Marketing”)

  • Continuously updating and expanding content
