The Topical Coverage Formula
Topical Authority = Topical Coverage x Historical Data. This formula, derived from our patent-backed research into how search systems evaluate domain expertise, gives you a concrete, measurable framework for content strategy.
Breaking Down Topical Coverage
Topical coverage is the percentage of entity-attribute relationships within a topic that your content addresses. It is not about page count. A site with 10 comprehensive pages can have higher topical coverage than a site with 200 thin pages.
How to Calculate It
- 1Define the topic entity — What is the central entity of this topic cluster?
- 2Map all attributes — What are every relevant property, relationship, and sub-entity?
- 3Inventory your content — Which attributes does your existing content cover?
- 4Calculate coverage — Covered attributes / Total attributes = Coverage %
Example: "Project Management Software"
Total mapped attributes: 47 (features, pricing, integrations, team sizes, industries, deployment types, security, compliance, support options, comparison criteria, use cases...)
If your content covers 28 of 47 attributes: Coverage = 59.6%
Breaking Down Historical Data
Historical data represents the accumulated quality of user interactions with your content over time. Search systems track:
- How long your content has been live and ranking
- User engagement patterns (click-through rate, time on page, pogo-sticking)
- Update frequency and quality of updates
- Backlink accumulation from authoritative sources
Historical data is a multiplier. New content starts with a low historical data score, which increases as the content proves its value over time.
Why the Formula Is Multiplicative
The multiplication matters. A site with 90% topical coverage but only 3 months of historical data scores lower than a site with 70% coverage and 3 years of history. Conversely, 5 years of history multiplied by 30% coverage still produces a low score.
This explains a common frustration: new sites with excellent content struggle to outrank established sites with mediocre content. The historical data multiplier gives incumbents an advantage — but only if their coverage remains competitive.
How to Improve Each Component
Improving Topical Coverage (Faster Wins)
- 1Conduct entity-attribute mapping for your core topics — we do this through our Content Depth dimension analysis
- 2Identify coverage gaps — which attributes have you not addressed?
- 3Create content for each gap — not thin pages, but comprehensive attribute coverage
- 4Consolidate overlapping content — two pages covering the same attribute dilute each other
Improving Historical Data (Long-term Investment)
- 1Publish consistently — Search systems reward sustained publishing cadence
- 2Update existing content — Add new attributes, update values, expand coverage
- 3Build engagement — Better titles, better introductions, better content structure increase user signals
- 4Earn citations — Other sites referencing your content builds historical authority
How Patnick Measures This
Our Content Depth dimension directly scores topical coverage. We map the complete entity-attribute landscape for your core topics, compare it against your existing content, and calculate your precise coverage percentage. The gap between your current coverage and 100% is your content strategy roadmap.
We then track historical data signals through Search Console integration, monitoring how your coverage improvements translate into ranking and traffic gains over time.
