Topical authority
TL;DR
Topical authority is a domain's perceived expertise within a specific topic cluster, built through complete, well-linked content architecture.
Topical authority became one of the heaviest ranking levers between 2020-2026. Google evaluates not just individual pages but whether a domain commands the whole topic. A site with 60 interlinked crypto-mining articles outranks in that niche even a higher-DA site with 3 shallow posts.
Example
An agency building GEO topical authority: one pillar 'What is GEO', 10 supporting blogs, 30 glossary terms, all cross-linked and linked to the services page. This glossary is itself part of such a build.
Frequently asked questions
Does topical authority help for GEO?
Enormously. LLMs prefer domains that cover a topic completely — not standalone pages answering one question.
