SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It prevents missing or incorrect Schema.org structured data by detecting existing markup, validating it against common rich result expectations, and generating correct JSON-LD that search engines can reliably parse.

Core Features & Use Cases

  • Detects structured data in multiple formats: Finds JSON-LD, Microdata, and RDFa and reports what’s present.
  • Validates for common issues: Checks required properties, supported rich result types, JSON-LD correctness, data types, date formats, and URL requirements.
  • Generates production-ready schema markup: Produces truthful JSON-LD snippets using templates, with guidance on schema type selection and deprecated/restricted types.
  • Use case: Audit a product or local business page, identify schema gaps or invalid fields, then generate corrected JSON-LD for implementation and reporting.

Quick Start

Run the schema audit for your page URL and request a validation report plus ready-to-paste JSON-LD.

FAQPage Schema
How do I audit a web page for missing or invalid Schema.org structured data?▼

To audit structured data, the Skill parses page source code, detects existing JSON-LD, Microdata, or RDFa markup, and validates it against rich result requirements to flag missing properties or invalid fields.

How do I generate JSON-LD structured data for rich results?▼

You generate JSON-LD structured data by providing page details, and the Skill outputs production-ready JSON-LD snippets using Schema.org templates, enforcing correct @context/@type declarations and required property data types.

Does this schema validation tool check for deprecated Schema.org types and property errors?▼

Yes, schema validation checks for deprecated and restricted Schema.org types, validates required properties, enforces JSON-LD best practices, and verifies date formats and URL requirements for rich result eligibility.

What is the best way to fix incorrect JSON-LD markup on a product or local business page?▼

The best way to fix incorrect JSON-LD markup is to run a schema audit that identifies validation errors, then generate corrected JSON-LD snippets that satisfy structured data requirements for product or local business rich results.

Can I detect Microdata and RDFa on a page in addition to JSON-LD?▼

Yes, structured data detection scans the page source and reports all present formats, finding JSON-LD, Microdata, and RDFa markup to give a complete view of existing schema implementation.

Why does my structured data not show up in Google rich results despite being on the page?▼

Structured data may fail to generate rich results if it contains invalid fields, missing required properties, incorrect data types, or deprecated schema types, all of which this validation process detects and reports.
