  Audit and fix HTML metadata including page titles, meta descriptions, canonical URLs, Open Graph
  tags, Twitter cards, favicons, JSON-LD structured data, and robots directives. Use when adding
  SEO metadata, fixing social share previews, reviewing Open Graph tags, setting up canonical URLs,
  or shipping new pages that need correct meta tags.

## Workflow

1. Identify pages with missing or incorrect metadata (titles, descriptions, canonical, OG tags)
2. Audit against the priority rules below — fix critical issues (duplicates, indexing) first
3. Ensure title, description, canonical, and og:url all agree with each other
4. Verify social cards render correctly on a real URL, not localhost
5. Keep diffs minimal and scoped to metadata only — do not refactor unrelated code
## when to apply

Reference these guidelines when:
- 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 metadata defaults
- adding structured data (JSON-LD)
- changing locale, alternate languages, or canonical routing
- shipping new pages, marketing pages, or shareable links

## rule categories by priority

| priority | category | impact |
|----------|----------|--------|
| 1 | correctness and duplication | critical |
| 2 | title and description | high |
| 3 | canonical and indexing | high |
| 4 | social cards | high |
| 5 | icons and manifest | medium |
| 6 | structured data | medium |
| 7 | locale and alternates | low-medium |
| 8 | tool boundaries | critical |

## quick reference

### 1. correctness and duplication (critical)

- define metadata in one place per page, avoid competing systems
- do not emit duplicate title, description, canonical, or robots tags
- metadata must be deterministic, no random or unstable values
- escape and sanitize any user-generated or dynamic strings
- every page must have safe defaults for title and description

### 2. title and description (high)

- every page must have a title
- use a consistent title format across the site
- keep titles short and readable, avoid stuffing
- shareable or searchable pages should have a meta description
- descriptions must be plain text, no markdown or quote spam

### 3. canonical and indexing (high)

- canonical must point to the preferred URL for the page
- use noindex only for private, duplicate, or non-public pages
- robots meta must match actual access intent
- previews or staging pages should be noindex by default when possible
- paginated pages must have correct canonical behavior

### 4. social cards (high)

- shareable pages must set Open Graph title, description, and image
- Open Graph and Twitter images must use absolute URLs
- prefer correct image dimensions and stable aspect ratios
- og:url must match the canonical URL
- use a sensible og:type, usually website or article
- set twitter:card appropriately, summary_large_image by default

### 5. icons and manifest (medium)

- include at least one favicon that works across browsers
- include apple-touch-icon when relevant
- manifest must be valid and referenced when used
- set theme-color intentionally to avoid mismatched UI chrome
- icon paths should be stable and cacheable

### 6. structured data (medium)

- do not add JSON-LD unless it clearly maps to real page content
- JSON-LD must be valid and reflect what is actually rendered
- do not invent ratings, reviews, prices, or organization details
- prefer one structured data block per page unless required

### 7. locale and alternates (low-medium)

- set the html lang attribute correctly
- set og:locale when localization exists
- add hreflang alternates only when pages truly exist
- localized pages must canonicalize correctly per locale

### 8. tool boundaries (critical)

- prefer minimal changes, do not refactor unrelated code
- do not migrate frameworks or SEO libraries unless requested
- follow the project's existing metadata pattern (Next.js metadata API, react-helmet, manual head, etc.)

## review guidance

- fix critical issues first (duplicates, canonical, indexing)
- ensure title, description, canonical, and og:url agree
- verify social cards on a real URL, not localhost
- prefer stable, boring metadata over clever or dynamic
- keep diffs minimal and scoped to metadata only

Overview

This skill helps teams ship correct, consistent, and complete page metadata so pages index and share reliably. It applies lightweight, practical checks and fixes for titles, descriptions, canonicals, social cards, icons, structured data, and locale alternates. The goal is minimal, safe diffs that respect existing metadata patterns and tool boundaries.

How this skill works

Run the skill to inspect a page or a specific file for metadata violations. It reports each violation with the exact snippet, a one-sentence explanation of why it matters, and a concrete code-level fix you can apply. The skill enforces determinism, prevents duplication, and prioritizes critical issues like canonical, indexing, and social card mismatches.

When to use it

  • When adding or changing page titles or descriptions
  • When implementing Open Graph or Twitter card metadata
  • When setting canonical URLs, robots, or noindex rules
  • When adding favicons, manifest, or theme-color
  • When introducing JSON-LD structured data
  • When localizing pages or adding hreflang alternates

Best practices

  • Define metadata in one place per page and avoid competing systems
  • Prefer stable, deterministic values; never emit random or time-based values
  • Keep titles short; provide plain-text descriptions for shareable pages
  • Ensure canonical equals og:url and matches the preferred public URL
  • Use absolute URLs for social images and validate recommended dimensions
  • Limit JSON-LD to accurate, rendered content and include only one block when possible

Example use cases

  • Scan a new marketing page to ensure it has title, description, canonical, og tags, and a social image with absolute URL
  • Audit a site migration to remove duplicate titles/descriptions and fix canonical routing
  • Validate staging previews are noindex and production pages are indexable
  • Fix duplicate metadata emitted by framework defaults plus a custom head component
  • Review JSON-LD to remove invented ratings or prices and align structured data with page content

FAQ

What does the skill change automatically?

The skill does not change files automatically unless you request edits; it reports precise violations and provides exact code suggestions to apply manually or via your preferred tooling.

Will it introduce new SEO libraries or refactor frameworks?

No. The skill recommends minimal diffs and follows the project’s existing metadata pattern; it avoids adding new frameworks or migrating SEO libraries unless explicitly asked.
