SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Web pages often lack valid structured data, causing them to miss rich results in Google Search. This Skill detects existing schema markup, validates it against Google's requirements, and generates correct JSON-LD so pages qualify for rich snippets. ## Core Features & Use Cases - Detection & Validation: Scan pages for JSON-LD, Microdata, and RDFa, then check required properties, data types, and common errors like missing @context or relative URLs. - Up-to-Date Type Guidance: Flags deprecated types (HowTo, SpecialAnnouncement, Dataset) and restricted ones (FAQ limited to government and healthcare sites) based on current Google policy. - JSON-LD Generation: Produces ready-to-use templates for Organization, LocalBusiness, Article, and other active schema types with clearly marked placeholders. - Use Case: Point the Skill at a product page URL to audit its existing markup, receive a SCHEMA-REPORT.md with validation results, and get corrected generated-schema.json snippets to paste into the site. ## Quick Start Analyze the schema markup on https://example.com/product-page and generate valid JSON-LD for any missing or invalid types.

FAQPage Schema
How do I add schema markup to a web page?â–¼

Add JSON-LD inside a script tag with type application/ld+json in the page HTML. Identify the page type, select the matching schema type, and include all required and recommended properties with truthful data.

How to validate JSON-LD structured data for Google rich results?â–¼

Validate JSON-LD by checking required properties per schema type against Google's supported rich result types. Common errors include missing @context, invalid @type, relative URLs, wrong data types, and invalid date formats.

JSON-LD vs Microdata vs RDFa for structured data?â–¼

JSON-LD is Google's stated preferred format and should be the primary choice. Microdata uses itemscope and itemprop attributes, while RDFa uses typeof and property attributes, both embedded directly in HTML elements.

Which schema types are deprecated by Google?â–¼

Deprecated types include HowTo, SpecialAnnouncement, CourseInfo, EstimatedSalary, LearningVideo, ClaimReview, VehicleListing, Practice Problem, and Dataset. FAQ markup is restricted to government and healthcare authority sites only.

Does JavaScript-injected structured data work for SEO?â–¼

Structured data injected via JavaScript may face delayed processing per Google's JS SEO guidance. For time-sensitive markup like Product and Offer, include JSON-LD in the initial server-rendered HTML instead.
