Schema Confidence Score™ is a proprietary Ivica Srncevic metric that evaluates how accurately, consistently, and comprehensively structured data represents the entities, attributes, and relationships on a page. It measures schema correctness, completeness, alignment with on‑page content, and the strength of entity anchoring — without being affiliated with Google or any search engine.
What the metric measures
1. Schema Accuracy
Does the schema correctly represent:
- the primary entity
- entity type
- attributes
- relationships
- expected properties
2. Schema Completeness
Does the schema include:
- required properties
- recommended properties
- contextual properties
- nested entities
- relationship definitions
3. Schema–Content Alignment
Does the structured data match the visible content?
- no contradictions
- no missing attributes
- no mismatched values
- no phantom entities
This is where most sites fail.
4. Entity Anchoring Strength
How strongly schema reinforces:
- entity identity
- entity role
- entity relationships
- entity hierarchy
This is critical for AI interpretation.
Scoring Model
| Component | Weight |
|---|---|
| Schema Accuracy | 35% |
| Schema Completeness | 30% |
| Schema–Content Alignment | 25% |
| Entity Anchoring Strength | 10% |
