Homepage and top landing pages
These pages often drive the most traffic and shape first impressions for prospects and customers.
How to Monitor Website Uptime
Website uptime monitoring is one of the simplest ways to protect revenue, leads, and customer trust. The goal is to know when an important page becomes unavailable before users start telling you about it.

What real uptime monitoring checks — and the signals a basic ping misses.
Why monitoring website uptime matters
Most businesses depend on a small set of pages to drive results. That may be the homepage, a pricing page, a signup path, a checkout flow, or a campaign landing page. If one of those pages goes down, the impact starts immediately.
Manual checking is not enough. By the time someone notices a problem, the outage may already have cost traffic, conversions, and customer trust. A website monitoring tool closes that gap by checking key pages continuously.
How to monitor website uptime effectively
Start by choosing the pages that matter most to the business, not every page on the site. Monitor the routes tied directly to sales, signups, support, or account access.
NorthDuty monitors uptime with a real Chromium browser, not a simple HTTP ping. That means SSL validity, DNS resolution, blank-page detection, JavaScript errors, API call tracking, and performance are all captured in the same check that confirms whether the page responded. The result feeds a 0–100 health score built from four weighted components — Uptime (30), Performance (25), Errors (15), and Stability (10) — normalized over whatever was measured.
On the Uptime component specifically: a healthy HTTP response contributes a full score. A navigation error deducts 25 points, an invalid SSL certificate deducts 25 points, an SSL certificate expiring within 7 days deducts 15 points, and expiry within 30 days deducts 5 points. Checks run every 1, 5, or 15 minutes per project.
Finally, make sure alerts reach the right people quickly. NorthDuty supports nine alert channels including email, Slack, Discord, Teams, Google Chat, webhooks, Telegram, WhatsApp, and SMS. Uptime monitoring works best when it leads to fast action, not just a dashboard that someone checks later.
Examples of pages to monitor first
Choose pages where downtime creates immediate business pain.
Login and account access pages
If users cannot log in, the support burden rises quickly and trust drops fast.
Product, pricing, and signup pages
These pages sit close to revenue and usually deserve continuous monitoring.
Checkout and payment routes
For ecommerce teams, these are some of the most expensive pages to leave unmonitored.
Best practices for website uptime monitoring
A few simple decisions make uptime monitoring much more useful.
- Monitor business-critical pages before less important routes
- Use checks that confirm a page is usable, not just online
- Review slow pages as well as fully unavailable pages
- Alert the people who can actually act on the issue
- Pair uptime monitoring with website health monitoring for broader coverage
- Revisit the monitored page list after launches, redesigns, and new campaigns
What uptime monitoring catches — and what it misses
Uptime is the floor. It is worth having on every site, and it is worth being clear about its blind spots.
| Failure | Does an uptime check catch it? | What does |
|---|---|---|
| Server down, DNS failure, expired domain | Yes | Uptime checks |
| SSL certificate expired | Usually, as a failed HTTPS request | SSL expiry monitoring gives days of warning instead |
| Page returns 200 but renders blank | No — the status code is fine | A rendered health check |
| Add to cart or checkout stops working | No | A real-browser journey |
| Contact form submits but sends nothing | No | A journey that checks the destination |
| Layout broken by an update | No | A journey that fails at the missing element, with a screenshot |
| A third-party script fails | No | JavaScript error capture during a rendered check |
How often to check, and from where
Every 1 to 5 minutes is the right range for anything that earns money: at a 15-minute interval an outage can run most of an hour before anyone knows. Confirm failures from a second location before alerting, which removes most false alarms without delaying real ones.
Then decide what a check actually does. Requesting a URL proves the server answered. Rendering the page in a real browser proves it drew. Running a journey proves a customer could act. Most sites need the first on everything, and the third on the two or three flows that matter.
Conclusion
If your website drives revenue, signups, or customer access, uptime monitoring is not optional. It is the fastest way to reduce the delay between a page going down and your team finding out.
NorthDuty helps teams move beyond manual checks by monitoring important pages continuously and connecting uptime to broader website health and journey monitoring.

What Is Uptime Monitoring?
Uptime monitoring checks whether your server responds, but it can't see broken checkouts, failed forms, or broken user journeys. Here's what you're missing.
Read What Is Uptime Monitoring?Frequently Asked Questions
Short answers that summarize the practical takeaways from this guide.
Is uptime monitoring enough on its own?
No. It proves the server answered, not that the site works. Blank pages, broken layouts, failed forms and checkout errors all return HTTP 200. Uptime is the floor — add rendered page checks and a journey on each flow that makes money.
What is the best way to monitor website uptime?
Use a browser-based check — not a simple ping — on the pages that matter most to the business. That way you catch not just full outages but also SSL expiry, blank pages, and JavaScript failures that a 200 response check would miss. Set alerts so the right people know immediately.
Which pages should I monitor first?
Start with the homepage, landing pages, pricing pages, product pages, login, signup, and checkout routes because they usually have the most direct business impact.
What does NorthDuty's health score include beyond uptime?
The 0–100 health score has four weighted components: Uptime (30), Performance including load time, FCP, and LCP (25), Errors including JavaScript and API failures (15), and Stability including blank-page detection and CLS (10), normalized over whatever was measured. Security, accessibility, and SEO are scored separately, and journeys are reported on their own.
Is uptime monitoring enough?
It is a strong starting point, but most important websites also need broader health monitoring. Pages can return 200 OK while still being blank, slow, or throwing JavaScript errors.
