What problem does it solve? Adding structured data to web pages is error-prone and requires knowing which schema.org types Google supports, which properties are required, and how to validate the markup. This Skill guides the implementation of correct JSON-LD schema markup so pages become eligible for rich results like star ratings, FAQs, and breadcrumbs in Google search. ## Core Features & Use Cases - Schema Type Implementation: Generates complete JSON-LD markup for Organization, WebSite, Article, Product, SoftwareApplication, FAQPage, HowTo, BreadcrumbList, LocalBusiness, and Event types with required and recommended properties. - Multi-Type Composition: Combines multiple schema types on a single page using @graph with proper entity references. - Validation & Debugging: Provides a systematic debugging workflow using Google Rich Results Test, Schema.org Validator, and Search Console when rich results fail to appear. - Use Case: An e-commerce team needs product pages to show price, availability, and star ratings in Google. The Skill produces complete Product schema with Offer, AggregateRating, and Review markup plus BreadcrumbList, ready to paste into the page template. ## Quick Start Ask the assistant to add Product and BreadcrumbList schema markup in JSON-LD to your product page template.
