name: vkc-seo-metadata description: Standardize Next.js metadata in VKC (generateMetadata, buildPageMetadata, canonical, alternates, OG, Twitter, robots/noindex).

VKC SEO Metadata (generateMetadata)

When to use

• You touch generateMetadata or page metadata behavior.
• You need canonical / alternates (hreflang) alignment for i18n routes.
• You change OpenGraph(OG) / Twitter previews.
• You change src/app/sitemap.ts or src/app/robots.ts.
• You need robots control (e.g. noindex, gated pages, admin-only pages).

Hard rules (this repo)

• Prefer buildPageMetadata from src/lib/seo/metadata.ts to avoid drift.
• Always set:
  • alternates.canonical
  • alternates.languages
• If a page should not be indexed, set robots in metadata (do not rely on ad-hoc tags).

Canonical references

• Metadata builder: src/lib/seo/metadata.ts (buildPageMetadata)
• Sitemap: src/app/sitemap.ts
• Robots: src/app/robots.ts
