Common problems we detect and how to resolve them

1

LinkedIn preview requirements that matter

LinkedIn cards depend on clean metadata, reachable images, and stable canonical URLs.

Why it happens
  • Missing `og:title`, `og:description`, `og:image`, or `og:url` values.
  • Image URLs requiring cookies or expiring tokens.
  • Conflicting metadata across server-side and client-side rendering paths.
How to fix it
  • Set complete Open Graph fields in the initial HTML response.
  • Keep share images public and high-resolution.
  • Ensure canonical and og:url both point to the final destination.

Why LinkedIn can show stale or unexpected cards

Even after metadata fixes, LinkedIn may continue showing previous preview state until recrawled.

Why it happens
  • Platform cache windows and delayed recrawl timing.
  • A shared URL variant differs from your intended canonical URL.
  • Deploys temporarily serving old metadata from cache layers.
How to fix it
  • Confirm the canonical URL returns updated metadata right now.
  • Use LinkedIn Post Inspector to troubleshoot and request re-fetch when needed.
  • Rescan from ShareScan after changes to verify source metadata quality.

How to prevent repeat incidents

Manual checking is easy to skip during fast-moving launch windows.

Why it happens
  • No scheduled checks tied to release cadence.
  • No alert loop for ownership when metadata drifts.
How to fix it
  • Run preflight scans before campaign launch.
  • Verify your domain to unlock scheduled scans and URL management.
  • Send Slack reports so regressions are visible immediately.

Frequently Asked Questions

No. ShareScan scans and validates metadata, then tracks diffs and alerts. LinkedIn cache operations are handled in LinkedIn Post Inspector.

LinkedIn may still be serving cached metadata. Confirm your live HTML output first, then use LinkedIn Post Inspector to request an updated crawl.

The image can be blocked, too small, or unreachable. Validate `og:image` and ensure the URL is publicly accessible.

Use scheduled monitoring and trigger scans from release workflows so metadata issues are caught before traffic spikes.
