Why It Matters

Social sharing metadata ensures your content looks professional and compelling when shared on platforms like LinkedIn, Facebook, X (Twitter), Slack, and WhatsApp. Optimizing preview cards increases referral click-through rates, protects brand consistency, and prevents platforms from randomly selecting low-resolution page images or irrelevant text snippet fallbacks.

Essential Tags to Implement

  • <meta property="og:title" content="Compelling Title Here" /> - Open Graph Title

  • <meta property="og:description" content="Engaging summary for social readers" /> - Open Graph Summary

  • <meta property="og:image" content="https://example.com/images/og-card.jpg" /> - Preview Image URL

  • <meta property="og:url" content="https://example.com/canonical-url" /> - Canonical Link Location

  • <meta name="twitter:card" content="summary_large_image" /> - Large image card on X (Twitter)

Image Dimensions & Specs

Design preview images at 1200x630 pixels with an aspect ratio of 1.91:1. Keep files well under the platforms’ limits (5 MB for X, 8 MB for Facebook), ideally under 1 MB, so social bots fetch them quickly without timing out. After publishing, check the preview with LinkedIn’s Post Inspector or Facebook’s Sharing Debugger, which also refresh cached previews.
