The Open Graph Tags Checklist: What to Verify Before You Publish

Run through this before you consider Open Graph tags actually done:

1. Set a dedicated `og:image` sized correctly per platform (1200×630 is a safe general default) rather than letting the platform guess from the first image on the page.
2. Write an `og:description` distinct from the meta description if the ideal share copy differs from the ideal search snippet — they're serving different contexts.
3. Test previews on every major platform separately — Facebook, LinkedIn, and X/Twitter each cache and render Open Graph data slightly differently.
4. Refresh cached previews after changing tags — most platforms cache the old preview aggressively and need a manual re-scrape via their own debugging tool.
5. Double-check this after any site migration or major redesign, not just at launch.

None of these individually take long. The value is in doing all of them, every time, instead of remembering most of them most of the time.

Pair this with the UTM tracking parameters checklist if you're doing a fuller pre-launch pass.
