What is topical authority?
Topical authority is Google's perception that a site is a comprehensive, trusted source on a subject — not just any single keyword.
Why it matters more than keywords
A site with topical authority ranks new pages faster, resists algorithm updates, and is more likely to be cited by AI engines.
Building content clusters
One pillar page for the head topic; multiple supporting articles for sub-topics; every supporting article links back to the pillar.
Semantic SEO and topic coverage
Cover the full entity graph: related concepts, competing options, common questions, edge cases. Depth beats keyword density.
Internal linking strategy
Descriptive anchor text between related pages passes context, distributes PageRank, and helps Google model your topic map.
How Google measures topical depth
Signals include coverage breadth, entity co-occurrence, internal link graph density, and consistent publishing cadence.
