What problem does it solve?

It solves the problem of missing, incorrect, or poorly formatted Schema.org structured data that can prevent eligible rich results and limit search visibility.

Core Features & Use Cases

  • Schema detection & auditing: Finds JSON-LD, Microdata, and RDFa in a page and reports what is present or missing.
  • Validation for rich result eligibility: Checks required properties, data types, common formatting errors, and flags deprecated/restricted schema types.
  • Schema generation in JSON-LD: Generates truthful, implementation-ready JSON-LD (with clear placeholders when user input is required).
  • Output for implementation: Produces a schema report for fixes and generated JSON-LD snippets to paste into server-rendered or template markup.

Example use case: You have a service page that currently lacks valid structured data—this Skill helps you detect the gap, validate what’s wrong (or absent), and generate compliant JSON-LD for Service/LocalBusiness-related entities so search engines can interpret the page correctly.

Quick Start

Ask the Skill to audit a specific URL for schema markup and generate corrected JSON-LD recommendations for the appropriate schema types.

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

You audit structured data by scanning a web page to detect existing JSON-LD, Microdata, or RDFa markup. This process identifies missing or incorrect schema types and generates a validation report detailing required properties and syntax errors for rich result eligibility.

How do I generate valid JSON-LD for a local business service page?

You generate valid JSON-LD for a service page by creating implementation-ready structured data for Service and LocalBusiness entities. The generated markup includes clear placeholders for required user input and enforces data type rules to ensure search engines correctly interpret the page.

Why does my schema markup fail rich result eligibility checks?

Schema markup fails rich result eligibility checks due to missing required properties, incorrect data types, or common syntax and URL issues. A validation audit flags these specific errors, along with deprecated or restricted schema types, preventing search engines from generating rich results.

What is the best way to fix deprecated schema types on my website?

The best way to fix deprecated schema types is to validate the existing structured data against current Schema.org rules. This identifies deprecated or restricted types and outputs implementation-ready JSON-LD snippets to replace the invalid markup with compliant entities.

Can I validate Microdata and RDFa markup or only JSON-LD?

You can validate Microdata and RDFa markup in addition to JSON-LD. The auditing process scans all three structured data formats, detects what is present or missing, and generates compliant JSON-LD recommendations as the preferred output format for implementation.
