Frequently asked questions
▸ ▾ What size should the og:image be?
1200x630 pixels (a 1.91:1 ratio), under about 5MB, served over HTTPS at an absolute URL.
▸ ▾ Why isn't my new preview image showing?
Platforms cache previews aggressively. Use the platform's debugger to force a re-scrape, and make sure the image URL is absolute and publicly reachable.
