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

<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

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
