Open Graph Image Not Showing: 1200 x 630
If your Open Graph image is not showing, the usual culprits are a relative (not absolute) image URL, missing og:image:width and og:image:height tags, Open Graph tags injected by client-side JavaScript that scrapers never run, or a stale scraper cache. The correct og:image is 1200 x 630 pixels (1.91:1), served as an absolute URL in server-rendered HTML. Drop an image below and crop it to 1200 x 630 in your browser - nothing is uploaded.

Platform scrapers fetch your raw HTML once and do not execute JavaScript, so any og:image added on the client is invisible to them. They also cache aggressively, so even a fixed tag can keep showing the old (or blank) preview until you force a re-scrape with the platform's debugger.
Common mistake: The most common mistake is a relative og:image path (like /og.png) instead of an absolute URL (https://yoursite.com/og.png). Scrapers cannot resolve relative paths and fall back to a blank card. Always use an absolute URL, add explicit width/height, and re-scrape with the Facebook Sharing Debugger or LinkedIn Post Inspector.
Frequently Asked Questions
Most often: a relative image URL instead of an absolute one, missing og:image:width / og:image:height tags, OG tags added by client-side JavaScript (scrapers do not run JS), or a cached preview. Serve an absolute 1200x630 image in server-rendered HTML and re-scrape.
Use the platform debugger: the Facebook Sharing Debugger, LinkedIn Post Inspector, or by re-posting on X. Each re-fetches your page and clears the cached preview, so your corrected og:image shows on the next share.
1200 x 630 pixels, a 1.91:1 ratio, above 600px wide. Keep the important content in a centered 1080x600 safe zone and declare og:image:width and og:image:height so the card sizes correctly on the first share.
