Twitter Card Validator & X Preview

Validate Twitter Card and Open Graph tags for any URL. Preview the card on X and find missing title, description, image or card-type metadata.

How to Test a Twitter Card

Use this twitter sharing debugger to run a comprehensive twitter cards test for any page. Our validator checks essential tags including twitter:card, twitter:title, twitter:description, and twitter:image, then renders a realistic preview of your tweet.

Verify Live Twitter Card Tags

After updating your site, re-run the test to confirm the public page now exposes the new image, title, and description. LinkGlimpse does not clear or control X's platform cache.

How to Debug a Twitter Card

  1. Paste your URL and click “Preview Your Tweet Now.”
  2. Inspect the tweet and card preview, along with extracted tag values.
  3. Fix meta tags in your HTML template or CMS settings.
  4. Deploy your changes, then re-run the debugger twitter flow to verify.
  5. Share your link with confidence once the twitter card update is reflected.

Twitter Card Best Practices

  • Use summary_large_image for posts where the image should dominate the preview
  • Ensure images are at least 1200×630 and under a few MB for faster loads
  • Keep titles punchy and clear; make descriptions action-oriented
  • Use absolute HTTPS URLs for all assets, including images

Fix Common Twitter Card Problems

  • Outdated preview? Trigger a twitter card update by changing the image filename
  • Broken image? Verify the URL is reachable and returns 200 status
  • No card? Confirm twitter:card is set and meta tags are in the <head>

Twitter Card Validator Questions

What is a Twitter Card Debugger?

A Twitter Card Debugger (debugger twitter) is a tool that lets you preview and validate how a URL renders as a Twitter Card. It helps you test meta tags, detect issues, and see a live preview before sharing. With our twitter sharing debugger you can run a twitter cards test instantly and fix problems that could reduce visibility.

How do I refresh my Twitter Card cache?

Paste your URL and click “Validate Twitter Card.” LinkGlimpse fetches the latest public page metadata so you can confirm your deployed tags. It does not clear X's own cache; platform cache refreshes remain controlled by X.

Which Twitter Card types are supported?

We support Summary and Summary with Large Image. The tool validates twitter:title, twitter:description, twitter:image, and twitter:card values, and shows an instant preview of the tweet and card.

Can I debug a Twitter Card in other languages?

Yes. Our interface supports all URLs globally. If you search “depurar url twitter,” this is the same workflow—paste the URL, run the twitter cards test, and verify the live preview.
