Social preview monitoring for content & web teams

Check the metadata behind your LinkedIn previews.

Review Open Graph titles, descriptions and images on campaign and product pages. Find missing or conflicting values before your team shares the links on LinkedIn.

Start with a free scan. No account or credit card. Then choose weekly follow-ups by email or Slack for up to 10 report pages.

Paste a page, a domain, or up to 10 URLs, one per line.

Quick diagnosis

LinkedIn preview image missing or stale? Check these three things.

  1. Confirm the image in the source

    Scan the exact URL you plan to share. Check that og:image points to the intended public image and that your published HTML contains the tag. The image in your CMS editor is not proof of what the page serves.

  2. Check the image response

    Open the image URL without signing in. If it returns an error, a login screen or an expired asset, fix that first. Also check whether your CDN or firewall blocks the platform’s request.

  3. Refresh in LinkedIn Post Inspector

    Once the source is correct, inspect the URL in LinkedIn’s own tool and check the preview for a new post. LinkedIn says existing posts keep their original preview. A ShareScan scan cannot refresh LinkedIn’s cache.

A clear place to start

See the issue. Find the page. Follow up.

  1. Check the sourceInspect titles, descriptions and images in the metadata your pages serve.
  2. Review the findingsOpen affected pages and use the issue details to decide what needs fixing.
  3. Check again after changesRun another scan after a fix, or set up recurring checks for the pages that matter.

Previews are based on fetched metadata. Slack, LinkedIn and X may show a different or cached card.

From finding to fix

What to check and how to follow up.

Check 01

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.

What to do next

  • 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.
Check 02

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.

What to do next

  • 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.
Check 03

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.

What to do next

  • Run preflight scans before campaign launch.
  • Choose weekly follow-ups by email or Slack from the report.
  • Verify your domain when you need scheduled scans and URL management.

When your team needs broader coverage

Bring recurring checks into your publishing workflow.

Create a workspace and verify your domain to schedule scans, manage URLs and connect CMS or GitHub Actions triggers. The Free workspace plan covers up to 100 pages.

Before you start

A few useful details.

Can ShareScan refresh LinkedIn cache for me?

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

Why is LinkedIn still showing an old title?

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

Why is the preview image missing?

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

How do I stop regressions after each deploy?

Use scheduled or release-triggered scans in a verified workspace to review metadata issues after publishing changes.
