Open Graph validator FAQ
What the validator checks, how to read the results, and how to fix the most common Open Graph issues.
What does the Open Graph validator check?
It fetches your page's HTML and reads every Open Graph and Twitter Card meta tag — og:title, og:description, og:image, og:url, og:type, twitter:card and more. You get a 0–100 score, a pass/warn/fail checklist, and live previews showing how the link unfurls on X, Facebook, LinkedIn, Slack and Discord.
Why is my link preview not showing an image?
Most often the page is missing an og:image tag, the image URL is relative instead of absolute, or the file is too large or behind authentication. Use a full https URL to a 1200×630 image under ~5MB. After fixing tags, re-scrape with each platform's debugger so it refreshes its cache.
What is the correct Open Graph image size?
Use 1200 × 630 pixels (a 1.91:1 ratio). It's the universal sweet spot that renders cleanly on X, Facebook, LinkedIn and Slack without cropping. Keep the file under 5MB and use PNG or JPG. Smaller images may be shown as a tiny thumbnail instead of a large card.
Do I need both Open Graph and Twitter tags?
Open Graph tags cover Facebook, LinkedIn, Slack, Discord and most apps, and X falls back to them too. Adding twitter:card and twitter:image gives you explicit control on X, including the large summary_large_image layout. Setting both is best practice and takes only a few extra lines in your <head>.
Why don't my updated tags appear when I share the link?
Platforms cache the first version they scrape. After editing your meta tags, paste the URL into the platform's own debugger (Facebook Sharing Debugger, LinkedIn Post Inspector, X Card Validator) to force a fresh fetch. Changes then propagate to new shares, usually within a few minutes.
