Frequently asked questions

Do I need twitter: tags if I have Open Graph tags?

Mostly no: X falls back to og:title, og:description and og:image. Add twitter:card to choose the large image style.

Why was the official validator removed?

X removed its Card Validator; this preview shows the same fallbacks X applies.

Which pages can it read?

Public web pages that return HTML. Pages that need a login, private network addresses and pages built entirely with JavaScript can't be read.
