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)

<meta property="og:url" content="https://yourdomain.com/page">
