Open Graph tags are meta tags defined in your HTML <head> section that control how your page appears when shared on social media platforms like Facebook, LinkedIn, WhatsApp, and Discord. Key tags include og:title, og:description, og:image, og:url, and og:type. They were originally created by Facebook and are now widely adopted across all major social platforms.
The recommended og:image size is 1200×630 pixels for Facebook and most platforms. LinkedIn recommends 1200×628px. For Twitter summary_large_image cards, use 1200×628px or larger. The image should be at least 200×200px minimum. Always use absolute URLs (starting with https://) for og:image.
Twitter Cards (now X Cards) are meta tags specific to X (Twitter) that control how links appear on the platform. Tags include twitter:card, twitter:title, twitter:description, and twitter:image. If Twitter Card tags are missing, X falls back to Open Graph tags. The twitter:card type (summary, summary_large_image, app, player) determines the card layout.
Common reasons include: (1) Missing og:image tag, (2) Using a relative URL instead of an absolute URL for the image, (3) The image URL returns a 404 or requires authentication, (4) The image is too small (under 200×200px), (5) The image format is not supported (use JPEG, PNG, GIF, or WebP), (6) Platform cache — Facebook and LinkedIn cache OG data; use their debugger tools to refresh.
Facebook provides a Sharing Debugger tool at developers.facebook.com/tools/debug/. Paste your URL to see how Facebook reads your OG tags, and click "Scrape Again" to clear the cache. For LinkedIn, use the Post Inspector at linkedin.com/post-inspector/. For X, use the Card Validator in the X developer dashboard.
Open Graph tags do not directly affect search engine rankings. However, they indirectly impact SEO by improving click-through rates when links are shared on social media. A compelling og:title and og:description with an attractive og:image can significantly increase social engagement and referral traffic to your site.
