name: open-graph description: When the user wants to add, audit, implement, or optimize Open Graph metadata for social sharing, including og:title, og:description, og:image, og:url, Facebook previews, LinkedIn previews, or social share previews. For a full metadata lifecycle use page-metadata; for X-specific previews use twitter-cards. metadata: version: 2.0.0

SEO On-Page: Open Graph

Owns Open Graph writing and implementation rules for social previews. page-metadata owns the full-page lifecycle and release verification.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope (Social Sharing)

• Open Graph: Facebook-originated protocol; controls preview card when links are shared on social platforms

The 4 Essential Tags

Every shareable page requires these minimum tags:

<meta property="og:title" content="Your Page Title">
<meta property="og:description" content="Your description">
<meta property="og:image" content="https://yourdomain.com/image.png">
<meta property="og:url" content="https://yourdomain.com/page">

Tag	Guideline
og:title	Concise and useful in a sharing context; same page identity as SEO title, not necessarily identical text
og:description	Accurate social summary; may differ from the meta description without changing the promise
og:image	Absolute HTTPS URL; representative of the page; include dimensions when known
og:url	Stable public page identity; normally the same URL declared canonical

Recommended Additional Tags

Tag	Purpose
og:type	Content type: website, article, video, product
og:site_name	Website name; displayed separately from title
og:image:width / og:image:height	Image dimensions (1200×630px)
og:image:alt	Alt text for accessibility
og:locale	Language/territory (e.g., en_US); for multilingual sites

Image Best Practices

Item	Guideline
Size	Use a high-resolution image and verify the target platforms' current requirements; 1200×630 is a common cross-platform starting point
Format	Use a platform-supported web image format and verify the deployed response
URL	Absolute URL with https://; no relative paths
Unique	One unique image per page when possible

Common Mistakes

• Using relative image URLs instead of absolute https://
• Images too small or wrong aspect ratio
• Empty or placeholder values
• Missing og:url (canonical)
• Reusing a generic logo or unrelated image when a representative page image is available
• Copying SEO title/description mechanically when the share context needs different wording

Implementation

Next.js (App Router)

export const metadata = {
  openGraph: {
    title: '...',
    description: '...',
    url: 'https://example.com/page',
    siteName: 'Example',
    images: [{ url: 'https://example.com/og.jpg', width: 1200, height: 630, alt: '...' }],
    locale: 'en_US',
    type: 'website',
  },
};

HTML (generic)

<meta property="og:title" content="Your Title">
<meta property="og:description" content="Your description">
<meta property="og:image" content="https://example.com/og.jpg">
<meta property="og:url" content="https://example.com/page">
<meta property="og:type" content="website">
<meta property="og:site_name" content="Your Site">
<meta property="og:image:width" content="1200">
<meta property="og:image:height" content="630">
<meta property="og:image:alt" content="Alt text">

Testing

• Facebook: Sharing Debugger
• LinkedIn: Post Inspector

Preview services cache metadata. Test the deployed absolute URL and refresh the cache when supported. Also inspect the raw initial HTML; a client-only tag insertion may not be available to every scraper.

Consistency boundary

Open Graph and SEO metadata may use different copy because search and social feeds are different contexts. They must still identify the same page, describe the same product or content, and avoid unsupported claims. Do not require string equality.

• title-tag, meta-description: Search copy; may differ while preserving page identity
• twitter-cards: Twitter uses OG as fallback; add Twitter-specific tags for best results
