fixing-metadata

Audit and fix HTML metadata including titles, descriptions, canonical URLs, Open Graph tags, and structured data. Reference these guidelines when: - Covers eight priority categories: correctness and duplication, title and description, canonical and indexing, social cards, icons and manifest, structured data, locale and alternates, and tool boundaries - Ensures metadata consistency across page titles, descriptions, canonical URLs, and Open Graph tags; prevents duplicates and enforces deterministic values - Includes rules for social card rendering, favicon setup, JSON-LD validation, and hreflang alternates for localized content - Designed to work within existing metadata patterns (Next.js metadata API, react-helmet, manual head tags) without framework migration - Identify pages with missing or incorrect metadata (titles, descriptions, canonical, OG tags) - Audit against the priority rules below — fix critical issues (duplicates, indexing) first - Ensure title, description, canonical, and og:url all agree with each other - Verify social cards render correctly on a real URL, not localhost - Keep diffs minimal and scoped to metadata only — do not refactor unrelated code - adding or changing page titles, descriptions, canonical, robots - implementing Open Graph or Twitter card metadata - setting favicons, app icons, manifest, theme-color - building shared SEO components or layout...
