OGP Checker

Fetch a public page and review its Open Graph and Twitter/X card tags.

How to use it

  2. Run the check to fetch initial HTML through the SiteIndex metadata endpoint.
  3. Compare the returned tags and preview with the target's original HTML and the social platform's debugger.
What is OGP Checker?

Fetch a public page and review its Open Graph and Twitter/X card tags with a social preview.

How it works

SiteIndex fetches the public page, reads its Open Graph and Twitter/X meta tags, flags any missing fields, and renders a preview card similar to how the link would appear when shared.

Common uses
  • Confirm a page has the Open Graph tags needed for a rich social preview.
  • Check what title, description, and image will show when a link is shared.
  • Spot missing og:image or twitter:card tags before publishing.
Limitations
  • The metadata fetch does not execute the target page's JavaScript or guarantee a platform's cached preview.
  • The public URL and remote images require requests; avoid credentials, signed private links, or confidential targets.
Frequently asked questions
Why does my preview look different on the actual social network?
Each platform caches and renders previews slightly differently, and some require their own debugging tool to refresh a cached preview; this check reflects the tags found in the page's current HTML.
