Pages without an image show up as a plain text link on most platforms. Make a card in seconds with the free OG image generator, or automate it: the API's signed OG URLs go straight into og:image, one per page. For a fully custom design, render your own HTML template:
curl -X POST https://shotmint.creasework.com/v1/screenshot -H "X-API-Key: YOUR_KEY" -H "Content-Type: application/json" \
-d '{"html": "<div style=\"width:1200px;height:630px;display:grid;place-items:center;background:#4f46e5;color:#fff;font:700 64px sans-serif\">My post title</div>", "width": 1200, "height": 630}' \

og:title | The headline of the card. Keep it to about 70 characters or fewer. |
og:description | One or two lines under the title. Many platforms cut it off after about 200 characters. |
og:image | An absolute HTTPS URL. 1200×630 (1.91:1) works on X, LinkedIn, Facebook and Slack. |
og:url | The canonical URL, so shares of variants are counted as one page. |
twitter:card | Set it to summary_large_image to get a large image card on X; summary gives a small thumbnail. |
