What It Is
The Three Axes of Topical Authority is Koray Tugberk Gubur's framework for measuring how comprehensively a website covers its subject. While the Five Fundamentals evaluate what your site is and why it exists, the Three Axes measure how well it covers its topics. Think of it as a 3D map of your content universe — breadth, depth, and connections.
Why It Matters for Your SEO
Google rewards sites that demonstrate comprehensive topical coverage. A site that covers 100 subtopics shallowly will be outranked by one that covers 50 subtopics deeply with strong internal linking. The Three Axes help you understand which dimension needs investment: do you need more topics (Vastness), deeper content (Depth), or better linking (Connection)?
How Korvex Measures It
| Axis | What It Measures | Key Metric |
|---|---|---|
| Vastness | Breadth of topic coverage | Number of distinct subtopics and entities covered |
| Depth | Expertise per topic | Average content depth, word count, heading structure |
| Connection | Internal linking density | How well pages cross-reference each other |
Business-Type Adjustments
The Three Axes are adjusted based on your business type:
- National services: Vastness blended with geographic coverage —
original × 0.70 + geographic_coverage × 0.30(20 major UK cities = target) - International: Semantic network score boosted by language variants — up to +50% multiplier for multilingual content
- Local services: Connection emphasised with NAP consistency and local schema signals
- Ecommerce: Depth adjusted for product description quality and collection structure
How to Improve Your Score
- Vastness: Map all subtopics in your niche using the Content Opportunities page, then create content for gaps
- Depth: Expand thin pages (under 1,000 words) with genuine analysis, data, and expert commentary
- Connection: Use the Semantic Internal Linking engine to identify missing cross-links between related pages
- Geographic coverage (national/international): Create location-specific landing pages for your service areas
Business-Type Enhancements
The Koray V2 Business Type Enhancements module adapts scoring based on 7 business types:
LOCAL_SERVICE, NATIONAL_SERVICE, INTERNATIONAL, SAAS, ECOMMERCE, CONTENT, LEAD_GEN
National Service — Vastness Adjustment:
adjusted_vastness = original_vastness × 0.70 + geographic_coverage × 0.30- Geographic coverage:
min(100, (distinct_markets / 20) × 100)— 20 markets = full score
International — Semantic Network Boost:
international_multiplier = 1.0 + min(language_variants × 0.1, 0.5)- Each language variant adds 10% to the connection score, capped at +50%
Data Sources
- Scoring: Calculated during Phase 5 and SCIS recommendation refinement
- Business type: Configured in client settings
