What a monitor does
A monitoring service requests your page from servers around the world at regular intervals, often every one to five minutes. If the page fails to respond or returns an error, it sends an alert by email, text or an app notification. Reports show uptime percentages and response times over time.
Free plans exist and are enough for a typical small business site.
What to monitor
Watch the home page at minimum. Add your contact page, booking page or checkout. A keyword check goes beyond whether the server answers; it confirms that expected text appears, which catches blank pages and error screens that still return a normal code. Monitor the SSL certificate expiry date and domain expiry if the service offers it.
If the site depends on an outside service, such as a booking widget, check that too.
Choose intervals and alerts
Five-minute checks are common on free plans. Shorter intervals suit stores. To avoid false alarms from a brief network blip, set the monitor to confirm failure from more than one location or after two consecutive failures. Send alerts to more than one person and one channel, since an email alone might sit unread.
Agree who responds and what they do first.
Have a response plan
Write a short checklist. Check whether the problem is on your side or the visitor side, look at the host status page, test from another network, review recent changes such as plugin updates, and contact the host with details and the time the outage started. Know where your backups are and how to restore.
Keep contact numbers for your host and your web provider where you can find them without the website.
Learn from the reports
Slow response times often precede an outage. Repeated short failures may point to an overloaded plan or a failing plugin. Review the monthly report, and keep a record of incidents with causes. Use the data when deciding whether to upgrade hosting or change providers.
Also tell customers when a planned maintenance window will occur, and use a maintenance page that returns the correct temporary status code.
Beyond uptime: what else to watch
A site can be up and still broken. Add a test for the contact form by sending a scheduled submission to a mailbox you check, or use a synthetic monitor that clicks through a booking flow. Watch for sudden changes in page weight, which can signal a hacked file or a new heavy script.
If your host offers a status page or email notices for maintenance, subscribe. Planned downtime on their side should never surprise you.
Look for a plan that offers alert escalation, multiple locations, certificate checks and an easy way to share the status with staff. Read what happens to alerts if your own email is the thing that is down; a text message or app push is a useful second route.
Common questions
Is 100 percent uptime realistic?
Not really. Most hosts promise high availability, but short outages happen. Monitoring shows the actual record.
Do free monitors work?
For basic checks, yes. Paid plans add frequent checks, more locations and richer alerts.
Will monitoring slow my site?
No. The checks are a few requests per hour and have negligible impact.
