How to use the Facebook Sharing Debugger.

Facebook, Messenger, and Threads cache Open Graph data aggressively. After you update og:image or og:title, platforms may still show the old preview until you force a re-scrape.

Step 1 — Validate your tags first

Before using the debugger, confirm your live page serves correct tags. Use our link preview checker or OG tag generator. Missing an image? Design a 1200×630 OG image first.

Step 2 — Open the Sharing Debugger

Go to the Facebook Sharing Debugger, paste your page URL, and click Debug.

Step 3 — Click “Scrape Again”

If the preview is stale, click Scrape Again. Facebook re-fetches your HTML and updates the shared cache used by Messenger and Threads.

Common issues

  • Wrong image — Update og:image to an absolute HTTPS URL, then scrape again.
  • Image too small — Use 1200×630 px. See our OG image size guide.
  • Tags missing — Ensure tags are in server-rendered HTML, not injected by JavaScript only.
  • Still stale on LinkedIn — LinkedIn uses a separate cache. Use the LinkedIn Post Inspector too.
