For HowTo step sections (placement, copy, vs FAQ), use howto-section-generator.

What this skill does
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 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. Other engines Varies Yandex, DuckDuckGo, AI search tools (Perplexity, etc.) may use Schema.org for understanding even when they don't display rich results. Practical implication: Implement Schema.org markup for your content type. If Google doesn't show rich results for that type, Bing or AI systems may still use it. Always verify against Google's developer docs for Google-specific rich result eligibility. Rich Results: Google Support (2026) High-impact types: Product, Review snippets, Article/News, Video, Recipe, LocalBusiness, Event, Breadcrumb, Sitelinks searchbox, JobPosting. …
