Why doesn't my new OG image show up on Facebook?

Facebook caches scrapes aggressively. Use the Sharing Debugger (developers.facebook.com/tools/debug) to force a re-scrape after changing OG tags.

1200×630 px is the universal best size — works on Facebook, LinkedIn, Slack, Discord. Minimum 600×315 to avoid a small thumbnail. Aspect ratio is 1.91:1.

Do I need both Open Graph and Twitter Card tags?

Twitter falls back to OG, so OG alone is fine for both. Add twitter:card and twitter:image only if you want a different X preview.

Must the og:image URL be absolute?

Yes — https://example.com/share.png. Relative paths fail because scrapers don't know your domain context.
