How it works
- Paste the URL you want to share (for example
https://example.com/page). - The tool fetches the live page and reads its
og:andtwitter:meta tags. - It validates each required tag and loads the declared image.
- You get a visual card preview plus a pass/warn/fail list of every tag.
What it checks
- og:title — the headline shown on the shared card.
- og:description — the supporting text under the title.
- og:image — the preview thumbnail, plus whether it actually loads.
- og:url & og:type — the canonical link and content type.
- twitter:card — the card style (summary or large image).
- twitter:title & description — X-specific overrides when present.
- Image dimensions — whether the thumbnail meets recommended sizes.
Common use cases
- Before a launch or campaign — confirm a key page shares with a proper image and title.
- Fixing a blank preview — diagnose why a link shows no thumbnail.
- Brand consistency — make sure every shared page looks polished and on-brand.
- Auditing a whole site — spot-check templates that forgot social tags.
Example
Check a blog post and you might see a clean Facebook card with title and description, but a red flag that og:image points to a file that returns a 404 — which is exactly why the link has been sharing without a thumbnail.
Frequently asked questions
Is the Open Graph & Twitter Card Checker free?
Yes — completely free, no signup and no limits. Preview as many pages as you like with real, live tag data.
Why does my shared link have no image?
Usually the og:image tag is missing, points to a broken file, or the image is too small. Add a valid, properly sized image and re-check. Note that platforms cache previews, so you may need to refresh their cache after a fix.
How does this relate to my other meta tags?
Open Graph tags live alongside your title and description — review them all with the Meta Tag Analyzer and confirm overall page health with the On-Page SEO Audit. For writing the underlying snippet, see our meta description guide.
