Content Cluster
A content cluster is a group of thematically related pages organized around a central pillar page, with subtopic pages linking back to the pillar and to each other, creating a semantic web of expertise.
The cluster model replaces the old approach of creating isolated pages targeting individual keywords. Instead, you map out a topic, create a comprehensive pillar page, and build supporting content that covers subtopics in depth. All pages in the cluster link to each other.
For example, a "Technical SEO" cluster might include: a pillar page on technical SEO fundamentals, plus cluster pages on Core Web Vitals, robots.txt, sitemaps, structured data, JavaScript SEO, and crawl budget. Each cluster page links to the pillar and to related cluster pages.
Content clusters benefit SEO in three ways: they build topical authority (Google sees comprehensive coverage), they create strong internal linking (distributing authority), and they capture long-tail keywords (each subtopic page targets specific queries).

Pillar Page
A pillar page is a comprehensive, long-form piece of content that covers a broad topic at a high level and links to more detailed subtopic pages (cluster content), serving as the central hub of a content cluster.
Topical Authority
Topical authority is a site's demonstrated depth of expertise on a specific subject, built by publishing comprehensive, interlinked content that covers a topic from multiple angles.
Internal Linking
Internal linking is the practice of connecting pages within the same website using hyperlinks. It distributes link equity, establishes site hierarchy, and aids crawlability.
Hub and Spoke Model
The hub and spoke model is a content architecture pattern where a central hub page (comprehensive overview) links to multiple spoke pages (detailed subtopics), and each spoke links back to the hub.
