The content cluster model typically has one broad pillar page (covering a topic at a high level, like 'local SEO') linked to and from a set of narrower spoke articles that each go deep on one subtopic (like 'Google Business Profile optimization' or 'NAP consistency'). This structure serves search engines by clearly grouping related content through internal links, which supports topical authority — the sense that a site has comprehensive, connected expertise on a subject rather than one isolated article. It also serves users by making it easy to navigate from a broad overview into the specific subtopic they actually need. Building a cluster deliberately (mapping the pillar and its spokes before writing, rather than linking related posts together after the fact) tends to produce more complete topical coverage and cleaner internal linking than an ad hoc approach.
Example
A 'local SEO' pillar page links out to twelve spoke articles covering NAP consistency, Google Business Profile, local link building, and review management — each spoke linking back to the pillar.
