Open Graph Validator, Explained

When someone shares your link, Open Graph tags decide whether it appears as a rich card with your title, description and image, or a blank, ignorable line. This generator lets you build those tags with live previews for Facebook, LinkedIn, X/Twitter and Slack side by side, so you can see the same link the way each platform renders it.

It goes further than typing tags: it actually loads your og:image in the browser and reports the real dimensions and aspect ratio, warning you when the image is too small, below the recommended 1200×630, or a ratio that will crop badly. Those image problems are the number-one cause of 'my share has no picture'.

You can import a live URL to pull the existing Open Graph tags for auditing, and the output includes synced Twitter Card tags (since X reads og: as a fallback), all HTML-escaped so a quote or bracket in your copy can't break the markup.

Add the tags to your page's <head>, then force a re-scrape with each platform's sharing debugger to clear cached previews. Pair this with the Twitter Card Generator and the Meta Tag Validator for complete search-and-social coverage.

Getting the Best Out of Open Graph Validator

  • Use a 1200×630 image, it's sharp on retina screens and crops cleanly on every platform

  • Always use an absolute https URL for og:image; relative paths silently fail on social platforms

  • After deploying, re-scrape with the platform's debugger to clear the cached old preview

Open Graph Validator FAQs

Common questions about this tool, its workflow, and what to expect before you use it.

Enter a URL and the validator fetches its Open Graph and Twitter tags, checks the image, scores share-readiness and previews the card on Facebook, X, LinkedIn, Discord, WhatsApp and Google. You can also build tags from scratch and copy or download the fixed code.

1200 by 630 pixels, a ratio of about 1.91 to 1, is the recommended size for sharp, correctly cropped previews. The validator loads your image and warns if it is too small, under the recommended size or far from that ratio.

Usually the og:image tag is missing, uses a relative path instead of an absolute URL, is too small, or is not publicly reachable. The Open Graph validator checks for each of these and tells you which one applies.

X can fall back to Open Graph tags, but the validator outputs a twitter:card tag and the key Twitter tags anyway, kept in sync with your Open Graph values. You can choose between summary and summary_large_image cards.

Social platforms cache Open Graph data. After deploying your fixes, use the platform's own debugger or inspector to force a re-scrape. The tool links to those refresh tools so the new card shows up. Previews in this tool always show your current tags.
