Twitter Card驗證工具

預覽任意URL在Twitter/X上分享時的顯示效果。驗證所有Twitter Card元標籤。

如何使用本工具

1
Paste the full public URL (including https://) of the page you want to inspect.
2
Run the tool so the server fetches the page and parses its HTML head.
3
Read the status banner: green means card, title, and description were all found; red means at least one is missing.
4
Scan the tag table and the rendered card preview to see exactly which twitter: values came back and which show as missing.

Twitter（現稱X）使用帶有twitter:前綴的元標籤，在URL被分享時呈現富媒體卡片。最常見的類型是summary_large_image，它會顯示大圖、標題、描述和來源。本工具會擷取並驗證每一個Twitter專屬標籤，然後渲染出卡片，讓你看到受眾將會看到的效果。

Confirm a new blog post exposes twitter:card, twitter:title, and twitter:description before you publish it.
Debug why a shared link shows a bare URL instead of a rich card by spotting which required tag is missing.
Check that twitter:card is set to summary_large_image when you expect the wide-image layout rather than a small thumbnail.
Verify a twitter:image URL actually loads by viewing it in the rendered card preview.
Audit a competitor or reference page to see how they configure their five core twitter: tags.
Spot-check a staging or production deploy to catch templates that dropped the twitter: meta tags during a build.
