Social Preview Tester — OG Tags & Cards

Share social preview results, discuss Open Graph and Twitter card optimisation, and help others get their previews looking great.

Every page should have og:title, og:description, og:image and og:url, plus twitter:card for X. Use an image large enough for a full preview. Platforms cache previews, so after changing tags you may need their own debugging tools to refresh them. Share a link that previews badly and what you changed to fix it.
