About this free twitter card checker

Twitter/X uses twitter:card meta tags for link previews. Relying only on Open Graph sometimes yields cropped or generic cards.

Audit twitter:card, title, description, and image tags before launches and PR pushes.

What it checks

  • twitter:card type (summary, summary_large_image, etc.)
  • twitter:title, twitter:description, twitter:image

Why it matters for SEO

  • Large image cards outperform plain summaries for engagement.
  • Consistent branding on X drives traffic from social and community shares.

How to use this tool

  1. Run on pages you expect to be shared on X.
  2. Set summary_large_image with a 2:1 image where possible.
  3. Use Card Validator if previews still look wrong after deploy.

Common issues we help you catch

  • Missing twitter:image on large card templates
  • Card type mismatch with available image
  • Stale cache showing old preview

If I have Open Graph, do I need Twitter tags?
X can fall back to OG, but explicit Twitter tags give predictable previews. Best practice: set both.
