WordPress Monitoring UK: What to Monitor and Why Uptime Checks Aren't Enough
Most WordPress monitoring is a green dashboard that says the site is up. Meanwhile the incidents that actually cost UK businesses money — malware, Google blocklisting, silently failing forms, expired certificates — happen on sites that were 'up' the whole time. Here is what monitoring should actually cover, and how to get it.
- Uptime monitoring answers the least important question — the expensive incidents happen while the site is "up"
- Seven signals cover the real risk: uptime, file integrity, malware/blocklists, SSL and domain expiry, vulnerability disclosures, admin activity, and critical journeys
- Tooling is cheap; response is what you are really buying — an alert nobody acts on is worth nothing
The green-dashboard problem
Uptime monitoring is where everyone starts because it is free and easy: a service requests your homepage every minute and alerts you if the server stops answering. Useful — and wildly incomplete. The server answering a request tells you nothing about what it answered with.
Consider what a basic uptime check waves through: a homepage serving injected spam links to Google’s crawler, a checkout that errors at the payment step, a contact form that stopped delivering enquiries three weeks ago, a “Deceptive site ahead” warning turning away nine out of ten visitors. Every one of these sites is “up”. Every one of them is bleeding money.
The seven things worth monitoring
1. Uptime and response time. Still the foundation — but monitor response time as well as availability. A site that slows from 800ms to 8 seconds is telling you something (resource exhaustion, a compromised process, a failing host) long before it goes down.
2. File integrity. WordPress core files should not change between updates. When they do — or when new PHP files appear in uploads folders — that is the single most reliable early signature of a compromise. File-integrity monitoring catches attacks days or weeks before visible symptoms, and it is the check that matters most in the 30 days after any cleanup.
3. Malware and blocklist status. Google Safe Browsing, and the blocklists email providers use, can flag your site before you notice anything wrong — and once flagged, organic traffic collapses within hours. Daily blocklist checks turn “why did enquiries stop this month?” into a same-day alert. You can spot-check your site’s current status free in about a minute.
4. SSL certificate and domain expiry. The most preventable outage in existence, and it still takes businesses offline every day. Browsers show a full-page security warning the moment a certificate lapses. Expiry monitoring costs nothing and removes the risk entirely.
5. Plugin and theme vulnerability disclosures. Most WordPress compromises exploit a known vulnerability — one that was publicly disclosed, patched by the developer, and simply never updated on the victim’s site. Monitoring vulnerability feeds against your installed plugin list converts “we got hacked” into “we patched within 48 hours of disclosure”.
6. Admin account activity. New administrator accounts, privilege changes, and logins from unexpected countries are the behavioural signature of an account takeover. This is the check that catches stolen-credential attacks, which file scanning cannot see.
7. Critical user journeys. If the contact form, quote calculator, or checkout is how the site makes money, it deserves its own check — a synthetic test that actually submits the form or reaches the payment step on schedule. Form failures are the classic silent loss: nothing errors publicly, the inbox just goes quiet, and most owners find out weeks later from an annoyed customer who tried to reach them.
DIY monitoring: what’s realistic
A reasonable self-managed setup is genuinely achievable: a free uptime service, SSL expiry alerts, Google Search Console (which emails you about security issues and manual actions), and a reputable security plugin providing file-integrity scans and login alerting. Total cost: roughly nothing. If your site is a brochure that changes rarely and an outage costs you little, this is a sensible place to stop.
The limitation is not the tooling — it is the operating model. Alerts arrive at 2am, on holiday weekends, and during your busiest week, and each one needs someone to judge whether it is noise or an incident, then act. DIY monitoring degrades the same way all good intentions do: attentively for a month, occasionally by month three, and effectively not at all by the time it matters.
What managed monitoring changes
Managed monitoring inverts the model: the checks run continuously, but the alerts go to a team whose job is to respond — apply the urgent patch, investigate the file change, get the blocklisting reviewed — usually before you know anything happened. It is typically bundled within a WordPress maintenance service alongside updates and backups, which is the right way to buy it: monitoring detects, but somebody still has to fix.
For sites where an incident has compliance or revenue consequences — regulated businesses, e-commerce, lead-generation sites where a breach carries real cost — a security retainer adds the layer that pure maintenance does not: guaranteed response times and incident handling when a check finds something serious.
Either way, the test to apply to any monitoring arrangement — including one you build yourself — is the same: when a check fails at 2am on a Saturday, what happens next, and who does it? If the answer is “nothing, until someone looks”, you have dashboards, not monitoring.
