SEO for anything served as a web page — the plumbing (templates, routes, redirects, <head> metadata, JSON-LD, sitemaps, robots.txt) and the prose (posts, guides, landing copy, docs) so pages rank and get cited by AI answer engines. INVOKE when creating or editing page templates (HTML/JSX/TSX/Vue/Svelte/Astro), routes, metadata, or any content meant for the web — even when nobody says "SEO". Interface microcopy is [[ux-writing]], not SEO prose.
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 — build it and write it so search rewards it
SEO is cheaper to bake in than to bolt on: a correct heading structure costs nothing at build time, while fixing it after launch takes a crawl, a redeploy, and weeks of re-indexing. And the writing carries the same property — a page that nails one search intent with extractable structure earns rankings and AI citations that no retrofit recovers. Every rule below optimizes for the crawler, the answer engine, and the human reader simultaneously; they almost always want the same thing. Sections 1–14 are the plumbing (templates, URLs, redirects, markup); sections 15–22 are the editorial layer (intent, structure, evidence). A template-only change uses the first half; a prose-only change the second; a new page both.
## When to apply this

The line at the top of this page pins the label git:20260826.48c94ab, 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.
