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 Coverage: Implements Organization, WebSite, Article, Product, SoftwareApplication, FAQPage, HowTo, BreadcrumbList, LocalBusiness, and Event schema with required and recommended properties. - Multi-Type Composition: Combines multiple schema types on one page using @graph, with complete JSON-LD examples in the references directory. - Validation & Debugging: Provides a systematic workflow using Google Rich Results Test, Schema.org Validator, and Search Console to fix errors and diagnose missing rich results. - Use Case: An e-commerce team needs product pages to show price, availability, and ratings in Google. The Skill produces complete Product schema with Offer, AggregateRating, and BreadcrumbList markup ready to deploy. ## Quick Start Ask the agent to add schema markup to your page, for example: add Organization and SoftwareApplication JSON-LD schema to my SaaS homepage.
