Common problems we detect and how to resolve them

1

Why publish-triggered scans matter

Preview regressions often start at publish time, especially when templates and content models evolve quickly.

Why it happens
  • CMS entries missing image fields or overriding metadata defaults.
  • Template-level changes that impact multiple page types at once.
  • Publishing workflows that skip metadata QA under deadline pressure.
How to fix it
  • Trigger scans from CMS webhooks on publish events.
  • Include newly published and high-priority evergreen URLs.
  • Review issue-level guidance immediately in report output.

How secure webhook-based monitoring works

Event-based scans need controlled access and predictable payload handling.

Why it happens
  • Unsigned webhooks or weak shared secret handling.
  • Inconsistent URL payloads between CMS environments.
  • No retry strategy for transient delivery failures.
How to fix it
  • Use secure webhook integration settings and shared secrets.
  • Normalize incoming URLs before scan requests are queued.
  • Send test reports to Slack to verify end-to-end routing.

How to prevent recurring publish regressions

Teams need feedback loops that connect publish events to release-quality ownership.

Why it happens
  • No monitoring between major launches.
  • No central trend view for metadata quality over time.
How to fix it
  • Combine webhook-triggered scans with scheduled monitoring.
  • Verify your domain to unlock URL management and 250-URL Free monitoring.
  • Track diff history to identify recurring metadata failure patterns.
