JSON-LD / Schema.org Structured Data Validation
Validates structured data that helps search engines better understand your pages and display Rich Results (rich snippets).
Measurement Items
- Parse and validate JSON-LD format
- Verify required fields by Schema.org type
- Detect Google Rich Results–supported types
- Check presence of Microdata and RDFa
- Provide errors, warnings, and improvement suggestions
- Include example JSON-LD snippets
Validated Schema Types
- Core schemas such as Organization, WebSite, BreadcrumbList
- Content-specific schemas such as Article, Product, FAQPage
- Specialized schemas such as Event, JobPosting, LocalBusiness
- Rating-related schemas such as AggregateRating, Review
- Media schemas such as VideoObject, Recipe, Course
Benefits of Structured Data
- Eligibility for Rich Snippets in search results
- Improved click-through rate (CTR)
- Better search engine understanding of content
- Optimization for Voice Search and AI Search
- Higher likelihood of Knowledge Graph inclusion
Testing Tool
Playwright-based browser automation collects structured data from actually rendered pages and applies Schema.org validation rules based on Google Rich Results Test standards. Performs JSON-LD parsing, required field validation, and Rich Results compatibility assessment.
Grade Criteria
| Grade | Score | Criteria |
|---|---|---|
| A+ | 90-100 |
• Perfect JSON-LD implementation • 100% Rich Results recognition • 0 errors, 0 warnings • All required fields present • Appropriate schema types applied |
| A | 80-89 |
• Key schemas valid • Implemented with JSON-LD • Most Rich Snippets recognized • 0 errors, ≤2 warnings |
| B | 70-79 |
• Some core schemas missing • Limited Rich Snippet recognition • ≤1 error, ≤5 warnings |
| C | 60-69 |
• Structured data incomplete • Unstable Rich Snippets • ≤3 errors, many warnings • C is the ceiling when JSON-LD is not used |
| D | 50-59 |
• Structured data inconsistent/duplicated • Rich Snippets not recognized • ≥4 errors (up to 10) • Incorrect schema types applied |
| F | 0-49 |
• No structured data implemented • No JSON-LD/Microdata present • Widespread errors • Rich Snippets not possible |
