Topical authority in SEO is the level of expertise and credibility a website demonstrates on a specific subject by comprehensively covering all related subtopics, entities, and user intents within a structured content cluster. It is the primary alternative to backlink-dependent ranking strategies — established through the Koray Framework’s hub-and-spoke content methodology and measured by a site’s ability to rank for an entire topic cluster rather than isolated queries.

What Is Topical Authority in SEO?
Topical authority in SEO is the degree to which a domain is recognized by search engines as a comprehensive, trustworthy source on a specific topic. It is established by covering all subtopics, entities, and intents within a topic cluster using hub-and-spoke architecture, Entity-Attribute-Value (EAV) content coverage, and systematic internal linking — as defined in the Koray Tuğberk Gübür semantic SEO framework.
Topical authority differs from domain authority (DA): DA measures overall link equity; topical authority measures semantic coverage depth on a specific subject. A site with low DA can outrank high-DA sites by establishing topical authority through comprehensive content clustering.
Why Is Topical Authority the Core of Modern SEO?
Topical authority is the core of modern SEO because Google’s NLP algorithms (BERT, MUM, Gemini) evaluate whether a site comprehensively covers a topic — not just whether individual pages match keywords. Sites with topical authority rank for entire query clusters without requiring a new backlink for each page, making it the most scalable SEO growth mechanism available.
| Signal | Traditional SEO | Topical Authority SEO |
|---|---|---|
| Ranking mechanism | Page-level keyword + backlinks | Domain-level topic coverage + NLP alignment |
| Scalability | One backlink campaign per page | One cluster builds authority for all pages |
| Algorithm resilience | Vulnerable to link devaluation | Built on semantic depth — update-resistant |
| Content ROI | Linear — each page independent | Compounding — cluster boosts all pages |
| Featured snippets | Incidental | Systematically earned via extractive answers |
How Do You Build Topical Authority with the Koray Framework?
To build topical authority with the Koray Framework: (1) define your hub topic and macro entity, (2) create a complete topical map of all subtopics, (3) publish hub and spoke pages covering all entities with EAV depth, (4) implement hub-spoke internal linking, (5) apply 40-word extractive answers under question H2s, (6) add Article and FAQPage schema, and (7) iterate based on GSC impression and position data.

What Is the Role of Entity Coverage in Topical Authority?
Entity coverage is the mechanism through which topical authority is built. For each subtopic page, Entity-Attribute-Value (EAV) coverage ensures that all relevant entities are identified, their attributes are defined, and specific values are provided. Comprehensive EAV coverage across the entire topic cluster signals to Google’s entity recognition systems that the domain is an authoritative source.

How Does Internal Linking Establish Topical Authority?
Internal linking establishes topical authority by creating a semantic map of the domain’s knowledge — hub pages link to all spoke pages, spoke pages link back to the hub and to adjacent spokes. This hub-and-spoke architecture communicates to Google that the site covers a topic comprehensively, boosting the entire cluster’s ranking potential through PageRank distribution and topical signal reinforcement.
