# SEO On-Page: Schema / Structured Data Guides implementation of Schema.org structured data (JSON-LD) for rich snippets, enhanced search results, and Generative Engine Optimization (GEO). **When invoking**: On **first use**, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output. ## Scope (On-Page SEO) - **Schema markup**: Schema.org types for rich results, AI search visibility, and machine-readable content - **Schema.org vs. search engines**: Schema.org defines 800+ types; each search engine supports only a subset for rich results ## Schema.org vs. Search Engine Support **Schema.org and Google Structured Data are not fully aligned.** Schema.org is an open vocabulary (800+ types); Google, Bing, and other engines each support only a curated subset for rich results. | Engine | Support | Notes | |--------|---------|-------| | **Google** | Subset only | Only types in [Google's search gallery](https://developers.google.com/search/docs/guides/search-gallery) generate rich results. Valid Schema.org markup not in Google's list won't produce enhanced snippets—even if technically correct. | | **Bing** | Subset; different | Supports JSON-LD, Microdata, RDFa, Open Graph. Some types (e.g., Product, Offer) have format-specific support. Check [Bing Webmaster docs](https://www.bing.com/webmasters/help/marking-up-your-site-with-structured-data-3a9...
