Open Graph Previewer - Facebook/Twitter/LinkedIn Card Preview

1. Preview a share card

1. Fill in the page URL, og:title, og:description, og:image and site name.
2. Check the card: is the title truncated, the description complete, the image ratio right?
3. Update the matching tags in your page head (this is a previewer — it does not modify your site).

2. Three frequent share-card problems

• Broken or blank image: og:image must be an absolute, publicly reachable URL — relative paths, intranet addresses and login-walled images all fail to fetch.
• Wrong ratio: platforms differ on the ideal og:image ratio (commonly 1.91:1); mismatches get cropped or padded.
• Changes not taking effect: platforms cache their crawls — force a re-scrape with each platform's debugger (Facebook Sharing Debugger, Twitter Card Validator, etc.).

3. The tags that actually drive click-through

Four tags carry nearly all the weight: og:title, og:description, og:image, and og:url. Everything else is edge-case plumbing. The image is where most posts lose the click: 1200x630 is the safe aspect (1.91:1), text under roughly 48px becomes unreadable in feed thumbnails, and center-crop assumptions differ across platforms — LinkedIn crops tighter than Twitter. After editing tags, use the platform debuggers (they force a re-scrape) or your shares keep showing the cached old card for days, which makes correct tags look broken.
