Structured Data Checker
Speak the language of search engines. Validate your JSON-LD schema to ensure you qualify for Rich Results.
How this Structured Data Checker Works
We scan your page for <script type="application/ld+json"> blocks and validate the JSON content against Schema.org standards. We check for required fields, syntax errors, and recommended properties.
- JSON-LD Extraction: We find all schema blocks, even nested ones.
- Type Validation: We verify if you are using recognized types like `Article`, `Product`, or `FAQPage`.
- Error Spotting: We highlight missing commas, unclosed brackets, or invalid property values.
Why it Matters for GEO
Rich Results
Structured data allows Google to display your content as "Rich Results" (Stars, faqs, images) in search results, significantly increasing Click-Through Rate (CTR).
Knowledge Graph
AI models use structured data to understand "Entities" (who, what, where). If you want Perplexity to know your CEO's name, put it in `Organization` schema.
