Topical authority is the concept that search engines evaluate not just individual pages but a site's overall coverage of a subject area. A site with 30 well-interlinked articles covering every aspect of 'project management' will outrank a site with one comprehensive guide, even if that single guide is excellent. Building topical authority requires systematic planning: identifying all the subtopics within a domain, creating content for each cluster, and linking related pieces together. This is why keyword clustering matters for strategy. Rather than publishing scattered articles on unrelated topics, teams that build topical authority focus their content investment on dominating specific subject areas before expanding to adjacent ones.
