Tips

Pro tips

  • Use `summary_large_image` for editorial content — much higher engagement than `summary`.
  • Image aspect ratio 2:1 (e.g. 1200×600) works everywhere.
  • Always set twitter:image to an absolute https:// URL.
Watch out

Common mistakes to avoid

  • Skipping validation before copying the output.
  • Not double-checking the input for hidden characters (leading spaces, invisible unicode).
  • Sharing sensitive data through URLs — use the copy button instead.
