Open Graph Checker
Verify og: and twitter: tags so links unfurl with the right title and image.
How it works
Enter a URL and the checker fetches the page and inspects the Open Graph and Twitter Card meta tags that social platforms and chat apps read when a link is shared.
Required tags (og:title, og:description, og:image, og:url) fail loudly when missing; recommended tags and Twitter Card fallbacks warn. Every finding includes the fix.

Frequently asked questions
Which tags are required for a link preview?
og:title, og:description, og:image, and og:url cover the core preview on most platforms. twitter:card upgrades the rendering on X; most other fields fall back to the OG tags.
Why does my og:image warn even though it's set?
Scrapers are strict about image URLs — the checker warns when og:image is a relative path, because many platforms ignore anything that isn't an absolute https URL.
