Read check results correctly
A reachable URL is evidence about a response, not a guarantee about content or SEO.
Passing, failed and unverified
Inspect the recorded response, redirect chain and final destination. Failed checks need review. Network failures, blocked requests and timeouts remain unverified. Checks do not judge whether a destination is relevant to the old page.
Keep background work running
Manual checks run while their page stays open. Persistent checks use WordPress cron and support cancellation and retry. A quiet site may run cron late. Check timestamps before trusting a monitoring report.
Know the boundaries
Network checks require PHP cURL and supported direct connections. All resolved target addresses must be public. Proxies, unavailable safe transport and private networks prevent verification. Export reports you need before retention removes them.
