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: Provides complete JSON-LD markup for Organization, WebSite, Article, Product, SoftwareApplication, FAQPage, HowTo, BreadcrumbList, LocalBusiness, and Event types with required and recommended properties. - Validation & Debugging: Walks through testing with Google Rich Results Test, Schema.org Validator, and Search Console, and helps diagnose why valid schema may not produce rich results. - Multi-Type Composition: Combines multiple schema types on one page using @graph, with implementation guidance for static sites, Next.js/React, and CMS platforms like WordPress. - Use Case: An e-commerce team needs product pages to show price, availability, and star ratings in Google. The Skill generates complete Product schema with Offer, AggregateRating, and BreadcrumbList markup ready to deploy. ## Quick Start Ask the assistant to add schema markup to your page, for example: add Product and FAQ schema markup in JSON-LD to my product page and validate it.
