Topical authority
What is topical authority?
Topical authority is the degree to which a site is treated as a credible source across an entire subject area rather than for individual keywords. It comes from covering a topic comprehensively, coherently interlinked, with consistent expertise signals.
It is built by clusters, not posts: a pillar page defining the topic, child pages covering each sub-question, and dense internal linking between them. Scattered high-volume posts across unrelated subjects do not accumulate it.
