Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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.

How to install

The exact contents, by fingerprint

mdr add kostja94/marketing-skills/schema-markup@sha256:577c25eacf90c9c7

The line at the top of this page pins the label v1.5.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
