Make your links
look right.

Understand the tags behind a shared link.

Set up page metadata in HTML, a CMS, or a framework.

Understand the two sets of sharing metadata.

Separate sharing metadata from search appearance.

Find conflicting tags, missing values, and bad URLs.

Check settings, permissions, and website metadata.

Inspect image access and LinkedIn’s fetched result.

Separate a click problem from a missing unfurl.

Work through card metadata and image fetching.

Check the live page before investigating stale previews.

Understand which tool can verify which result.

Compare live metadata with a platform’s stored preview.

Diagnose a missing or wrong link preview by checking the page response, metadata, image URL, redirects, and platform cache in order.

Find why Facebook shows no link image or an old preview. Check the exact URL, Sharing Debugger, page HTML, image response, and publishing context.

Choose dimensions and keep important content visible.

Troubleshoot an invalid or unreachable og:image URL: direct image responses, redirects, permissions, expired signatures, and public accessibility.

Investigate crawler access and security events.

Configure page metadata and dynamic share images.

Trace stale output through rendering and caches.

See why React or Vite meta tags can appear in DevTools but fail in link previews, and choose static HTML, prerendering, or server rendering.

Fix product, profile, and article links that all show your homepage preview. Compare route HTML, inherited metadata, redirects, and og:url.

Check Open Graph metadata locally, then use a public preview deployment or tunnel to test external fetching without confusing localhost and image URLs.
