Open Graph preview
See how a link looks when shared on Facebook, LinkedIn, X, Slack and iMessage, and what to fix in your og: tags.
Public pages only, one page per scan. First results in a few seconds; the accessibility check takes 10–20 s and the speed test up to 40 s. Reports stay unlisted unless a page has been scanned several times.
What this check looks at
We fetch the page like Facebook, LinkedIn, X and Slack do and read the Open Graph and Twitter Card tags: og:title, og:description, og:image (reachable, absolute, at least 1200×630, close to 1.91:1), og:url, og:type, og:site_name and twitter:card. Then we draw the card each platform would show, so you see the crop and the truncation before you post. Writing new tags? Draft a card from typed values.
