Common problems we detect and how to resolve them

1

What continuous monitoring catches

Metadata regressions often appear after deploys, template edits, and CMS updates that seem unrelated to social previews.

Why it happens
  • Shared layout changes touching title, description, or canonical fields.
  • Image pipeline updates that silently break `og:image` output.
  • Environment-specific behavior that only appears in production.
How to fix it
  • Scan priority URLs on a schedule and retain scan history over time.
  • Compare issue-level diffs between healthy and regressed runs.
  • Route alerts to Slack channels with clear ownership.

How timelines and diffs speed up fixes

Without a timeline, teams spend too long asking when a preview broke and why.

Why it happens
  • No baseline report to compare against.
  • No release-aware context when tags shift.
How to fix it
  • Use trend history to spot first-seen regressions.
  • Inspect field-level changes (`og:title`, `og:image`, `canonical`, and more).
  • Use Slack reports to coordinate content and engineering fixes quickly.

How to unlock scheduled scans on Free

Continuous monitoring requires verified ownership of the domain being scanned.

Why it happens
  • Unverified domains are limited to public ad-hoc scans.
  • No URL management workflow until ownership is confirmed.
How to fix it
  • Verify your domain in ShareScan to unlock scheduler and URL management.
  • Set recurring scans and watch up to 250 URLs on the Free plan.
  • Add GitHub Actions or CMS webhook triggers for event-based scans.
