SEO On-Page: Open Graph

Guides implementation of Open Graph meta tags for social media previews (Facebook, LinkedIn, Slack, Discord, etc.). Pages with proper OG tags get 2–3× more clicks than bare URL links.

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	Keep under 60 chars; compelling; match page content
og:description	150–200 chars; conversion-focused
og:image	Absolute URL (https://); 1200×630px recommended
og:url	Canonical URL; deduplicates shares

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	1200×630px (1.91:1 ratio) for Facebook, LinkedIn, WhatsApp
Format	JPG, PNG, WebP; under 5MB
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)

Implementation

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',
  },
};
