Share card preview
Paste a page address to see the card a link to it shows, before you post it anywhere.
What it checks
- og:title and og:description
- The headline and text on the card. Without them, sites fall back to the page title and meta description.
- og:image
- The picture on the card. Without it, most sites show a small grey box. Use 1200 × 630 pixels.
- twitter:card
- summary_large_image gets the full-width card on X; without it X shows a small one.
- og:url
- The address the card links to. Optional; most sites use the shared address.
It reads the HTML your server sends, before JavaScript runs, the way link-preview bots do. Sites cache cards, so a fix can take a while to show where a link was already shared.
