What its author says it does

Copied from the file, not written here

Page metadata for web — title/description, canonical, Open Graph, Twitter cards, JSON-LD structured data, robots/sitemap. Apply when building or auditing pages, landing pages, and shareable links (SEO and social previews).

Web metadata (SEO & social)

Sources: HTML living standard, Open Graph protocol (ogp.me), schema.org, Google Search Central.

Core (every page)

  • Unique <title> (~50–60 chars) and <meta name="description"> (~150–160 chars) per page — not a single global default.
  • <link rel="canonical" href="…"> — absolute URL; prevents duplicate-content splitting. One canonical per page.
  • <meta name="viewport" content="width=device-width, initial-scale=1">, correct <html lang>, charset utf-8.
  • <meta name="robots"> — index,follow for public pages; noindex for private/staging/duplicate. Ship a robots.txt + sitemap.xml.

Social previews

  • Open Graph (Facebook, LinkedIn, Slack, etc.): og:title, og:description, og:type, og:url (canonical), og:image (absolute URL, ~1200×630, <5MB), og:site_name, og:locale.
  • Twitter/X cards: twitter:card (summary_large_image), twitter:title, twitter:description, twitter:image. Falls back to OG if omitted, but set twitter:card explicitly.
  • Test previews before shipping (e.g. social debuggers); a broken/missing og:image makes shared links look unfinished.

Structured data

  • JSON-LD (<script type="application/ld+json">) with schema.org types relevant to the page: Organization/WebSite (home), Article/BlogPosting, Product, BreadcrumbList, FAQPage. Match the visible content (no markup for things not on the page).
  • Validate against schema.org / rich-results expectations.

Framework notes

  • Next.js: the Metadata API (export const metadata / generateMetadata) — per-route, not hardcoded in one layout.
  • Nuxt: useHead / useSeoMeta per page.
  • Don't hardcode strings — use i18n + data; dynamic pages generate metadata from their data.

Anti-patterns

  • Same title/description on every page; missing canonical; relative og:image; JSON-LD that doesn't match the page; noindex accidentally left on production.

  • test social previews before shipping pages

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
