Why does my OG/Twitter preview look different from production?

Platforms cache previews. After updating meta tags, use each platform’s debugger to refresh cache (e.g., Facebook Sharing Debugger, X Card Validator, LinkedIn Post Inspector).

What size should my Open Graph image be?

A common recommendation is 1200×630 (1.91:1) for Facebook/LinkedIn and 1200×628 for X large summary. Keep images under a few MB and use JPG/PNG/WebP.

Do I need both Open Graph and Twitter tags?

Twitter falls back to Open Graph in many cases, but adding explicit twitter:* tags ensures consistent previews across clients.

Why is my og:image ignored?

Common reasons: too small dimensions, blocked by robots.txt, 404/redirect loops, non-public URL, or unsupported content-type. The tool flags these issues.
