Open Graph & Social Preview Checker

When someone shares your link on LinkedIn, Facebook, WhatsApp, Slack or X, these platforms read Open Graph tags to build the preview card. This tool shows what they read and what is missing.

Checks performed

The three tags that matter

og:title (a short headline), og:description (one sentence), og:image (1200×630 px, under 5 MB, absolute https URL). Add twitter:card="summary_large_image" to get a large image on X.

Why previews fail

Relative image URLs, images blocked by robots.txt, or caches on the social platform that still hold an old version (use each platform’s debugger to refresh).

FAQ

Do Open Graph tags improve SEO?

Not directly, but attractive previews get more clicks and shares, which brings visitors and links.
