Free meta tag checker and link preview for any URL

See how any URL shows up on Google, Facebook and X before you share it.

Need one check only? Go straight to the Open Graph checker or the Twitter card validator.

What Metadata Scout checks

Metadata Scout is a free meta tag checker. Paste any public URL and it fetches the page once, reads the head, and shows what search engines and social networks will see. Warnings call out the common misses: no description, no og:image, no canonical. Nothing is stored beyond a one-hour cache, and there is no sign-in.

title, description, canonical, favicon

Google search preview

The title tag, meta description, canonical URL and favicon, laid out the way Google shows a result, so you can see the truncation before Google does.

og:title, og:description, og:image, og:url, og:site_name

Open Graph tags

og:title, og:description, og:image, og:url and og:site_name, rendered as a Facebook link preview. Relative image paths are resolved to absolute URLs. See the Open Graph checker.

twitter:card, twitter:title, twitter:description, twitter:image

Twitter cards

twitter:card, twitter:title, twitter:description and twitter:image, with the same fallback to Open Graph that X applies. X retired its own tool, so use the Twitter card validator instead.

lang, charset, viewport, robots, theme-color, icons, feeds, hreflang, JSON-LD

Everything else in the head

Language, charset, viewport, robots, theme color, every icon link, RSS and Atom feeds, hreflang alternates, and any JSON-LD structured data blocks.
