Full definition
Rather than ranking a single keyword in isolation, topical authority reflects whether a site comprehensively covers a domain—definitions, comparisons, workflows, and related subtopics—with accurate, updated material and sensible internal structure.
Signals include content breadth and quality, expert authorship where relevant, external recognition, and internal linking that forms coherent clusters. Thin scaled pages usually undermine authority rather than build it.
Answer engines tend to prefer sources that look like reliable topic references when synthesizing explanations. See Content Cluster, Pillar Page, and EEAT.
