More about the OG Tag Debugger
When a shared link isn't previewing correctly anywhere, on Facebook, on Twitter, in a Slack unfurl, the actual problem could be a missing Open Graph tag, a malformed Twitter Card tag, or both at once, and checking one platform's preview at a time doesn't reveal which underlying tag is actually broken or absent. This tool validates both Open Graph and Twitter Card meta tags for a URL together, flagging exactly which tags are missing or malformed rather than only showing how a link happens to render on one specific platform. Useful for diagnosing why a link isn't generating a preview on any platform at all, confirming both tag systems are present and correctly formatted after a site redesign, or catching a malformed og:image tag that's silently breaking previews everywhere it's shared.
Debug Open Graph and Twitter Card meta tags for any URL with detailed validation. The OG Tag Debugger is one of 900+ free developer tools on Toolblip - all open to use without a signup.
