When someone shares your link on Facebook, LinkedIn, Discord or Slack, the preview card — title, description and image — comes from your page’s Open Graph meta tags. If those tags are missing or wrong, your link shows up as a sad grey box instead of a rich preview. Our Open Graph Checker fetches any URL and lists every og: and twitter: tag it finds, so you can see exactly what social platforms will see.
This is the fastest way to debug sharing problems: a missing og:image is the most common reason previews look broken, while a mismatched og:url can send clicks to the wrong page. Content marketers use the checker to verify every article before promotion; developers use it after deploying new templates to confirm tags render correctly in production.
The tool also flags which recommended tags are absent — og:title, og:description, og:image, og:url and og:type — so you know precisely what to add. Pair it with our free Open Graph Generator to create a correct tag set, then re-check the page. No account needed, and checks run instantly from our server.

FAQs
Facebook still shows the old preview after I fixed my tags. Why?
Social platforms cache link previews. Use Facebook’s Sharing Debugger to scrape the URL again and clear the cached version.
What is the difference between og: tags and twitter: tags?
og: tags are the open standard used by Facebook, LinkedIn and most platforms; twitter: tags fine-tune how the card looks specifically on X. Setting both gives you full control.
Which image size works best for og:image?
1200×630 pixels is the widely recommended size — large enough to look sharp on high-resolution screens without slowing the page down.
