Website monitoring tells you when a site becomes unavailable or starts responding slowly. It is not a replacement for good hosting, but it gives you visibility before customers start reporting problems.
Monitor the Right URL
Monitor a public page that represents the real site. For shops or apps, also consider monitoring checkout or login flows with a more advanced tool.
Choose Alert Channels
Email alerts are useful, but they may be missed. For important sites, add SMS, chat, or incident-management alerts.
Avoid False Alarms
Set a sensible check interval and require more than one failed check before alerting. One failed request may be a temporary network issue.
Review Incidents
When monitoring alerts, record what happened and what fixed it. Over time, patterns become easier to spot.
Monitoring is most useful when someone is responsible for responding to it.
Start with External Availability
Monitor the public HTTPS URL from outside the hosting account at a sensible interval. Check the expected status code and, for an important page, a short piece of text so a branded error page is not mistaken for success. Add certificate-expiry monitoring and follow redirects to the canonical hostname.
Monitor Important Journeys Carefully
A homepage check will not detect a failed contact form, login or checkout. Add synthetic checks for critical workflows where the tool can run them safely without creating real orders or exposing credentials. Keep monitoring accounts restricted and exclude test messages from business reporting.
Design Alerts People Can Use
Send alerts to more than one responsible route and include the failed URL, time, region and error. Require several consecutive failures before paging somebody, but do not hide a prolonged fault behind excessive delay. Document who checks DNS, hosting, application logs and external providers.
Measure Recovery
Record when an incident began, when it was detected and when service returned. Review false alerts and missed failures. Monitoring should lead to better thresholds, clearer ownership and tested recovery - not simply a dashboard nobody opens.
