Topical Authority
Frameworks for building topical authority and measuring coverage dominance.
Authority Score Formula
Authority Score = (Topic Coverage %) × (Content Age Factor) × (Depth Multiplier)
Topic Coverage %
| Coverage | Status | Strategy | |----------|--------|----------| | 0-30% | Emerging | Focus on core topics first | | 30-60% | Developing | Fill major gaps systematically | | 60-80% | Authoritative | Target long-tail and edge topics | | 80%+ | Dominant | Maintain freshness, add depth |
Content Age Factor
| Age | Factor | Action | |-----|--------|--------| | Fresh (0-3 months) | 1.0x | Maintain quality | | Recent (3-6 months) | 0.9x | Monitor for updates needed | | Aging (6-12 months) | 0.8x | Refresh with new data | | Stale (12+ months) | 0.6x | Major update or consolidate |
Depth Multiplier
| Depth Level | Words | Multiplier | Content Type | |-------------|-------|------------|--------------| | Shallow | <500 | 0.5x | Definitions, news | | Standard | 500-1500 | 1.0x | How-tos, guides | | Deep | 1500-3000 | 1.2x | Comprehensive guides | | Exhaustive | 3000+ | 1.5x | Pillar content, research |
Topic Mapping Process
Step 1: Identify Core Topics
List all topics in your domain:
- Main categories (5-10)
- Subcategories per category (10-20 each)
- Long-tail variations (50-100 per subcategory)
Step 2: Audit Coverage
| Topic | Your Content | Competitor A | Competitor B | Gap | |-------|--------------|--------------|--------------|-----| | [Topic 1] | Yes/No/Partial | Y/N/P | Y/N/P | Priority | | [Topic 2] | | | | |
Step 3: Calculate Authority
Your Topics Covered: X
Total Topics in Domain: Y
Coverage %: X/Y × 100
Weighted Score = Σ(Coverage × Age × Depth) for each topic
Topic Cluster Structure
PILLAR PAGE (Exhaustive, 3000+ words)
├── Cluster 1: [Subtopic]
│ ├── Supporting Article A
│ ├── Supporting Article B
│ └── Supporting Article C
├── Cluster 2: [Subtopic]
│ ├── Supporting Article D
│ └── Supporting Article E
└── Cluster 3: [Subtopic]
└── Supporting Article F
Internal Links: Spokes → Hub → Spokes
Competitor Comparison
| Metric | You | Comp A | Comp B | Gap Analysis | |--------|-----|--------|--------|--------------| | Total topics covered | | | | | | Avg content depth | | | | | | Update frequency | | | | | | Backlink domains | | | | | | Author credentials | | | | |
Finding Competitor Topics
- Crawl their sitemap for content inventory
- Analyze top 50 pages by traffic
- Map their topic clusters
- Identify topics they rank for that you don't
Content Gap Analysis
| Gap Type | Indicators | Priority | |----------|------------|----------| | Missing topic | Competitor ranks, you don't | High | | Shallow coverage | Your content < 500 words | High | | Outdated | No update in 12+ months | Medium | | Missing format | They have video, you don't | Medium | | Weak depth | Your content less comprehensive | Medium |
