If your site is taking off (congrats!), you’ve outgrown finding out about a downtime incident from a customer, a friend, or worse, a sales lead that never materialized.

Website uptime monitoring is an automated way to know when your site is down (or effectively down). With it, you can get alerted quickly and fix issues before they turn into lost income, lost trust — or lost sleep.

This guide takes you from nothing → basic, reliable monitoring in one page. It includes recommended default settings, a decision tree, and a basic starter stack you can install right now.

What uptime monitoring is (and isn’t)

Uptime monitoring is an automated system that answers the question: Can actual users reach the stuff on my site that matters?

Depending on the type of monitor, the stuff that matters could be:

Your homepage loading over HTTPS
A specific page rendering the right content
Your server responding to a ping
That a port is reachable (for example, port 443 for HTTPS)

Uptime monitoring isn’t:

A complete performance audit (it won’t tell you why a page is loading slow the way other performance tools would)
A security suite (it won’t prevent attacks, but it can help you detect symptoms of an attack quickly)
A guarantee of an optimal user experience (a site can be up, but a key process could be broken—like login or checkout)

If you’d like a deeper dive for beginners, start here: what uptime monitoring is.

Monitor types: HTTP, keyword, ping, and port (and when to use each)

Think of monitor types as different questions you’re asking your site.

HTTP monitor (the main one for most sites)

Question: Does this URL respond successfully over HTTP/HTTPS?

Use HTTP monitoring when you want to see if:

Your site is reachable by the internet
Your web server is working as expected
Your URL isn’t giving off 5xx errors, timeouts, or unexpected redirects

Best for: blogs, sales & marketing sites, SaaS (software as a service) front ends, e-commerce sites
Why it’s the main one: it closely mirrors the user experience.

Keyword monitor (an upgrade to HTTP monitoring)

Question: Does the page not only load, but also load the content it should?

Keyword monitoring loads a page and looks for a specific keyword on it. It is how you catch things like:

A cached error page that still returns 200 (the successful response status code)
A “maintenance mode” page when the page shouldn’t be in maintenance mode
A sign-in page loading where the homepage should
A partial outage where the site loads but the app the site hosts isn’t working

Best for: sales pages, sign-in pages, checkout pages, dashboards
Rule of thumb: if signups or income depends on it, add a keyword check

Ping monitor (useful, but not enough by itself)

Question: Does this host respond to network pings?

Ping is a network command that checks to see if a host is reachable on the internet. Using the ping command can tell you if:

The server or network path is reachable

Ping can’t tell you:

If your site is actually delivering pages
If TLS/HTTPS is working
If the app your site hosts is causing errors

Best for: site infrastructure monitoring (when paired with HTTP), internal services like SaaS apps

If you’re choosing between ping and HTTP for a typical site, start with HTTP. Here’s a detailed breakdown: ping vs HTTP checks.

Port monitor (for specific services)

Question: Is a service reachable on a port (like 443 for HTTPS or 22 for SSH)?

Port monitoring helps determining if:

A firewall, load balancer, or service is or isn’t blocking access
A specific service is online and listening

Best for: technical teams, agencies that monitor client infrastructure, custom stacks
Common ports: 443 (HTTPS), 80 (HTTP), 25/587 (mail), 21 (FTP), 22 (SSH)

Check frequency, regions, and timeouts (recommended settings)

You don’t need your settings to be perfect. You just need reasonable defaults that catch important incidents without giving you alert fatigue.

Recommended starter defaults (that will work for most websites)

Check type: HTTP (plus one keyword check on your most important page)
Interval: every 5 minutes
Timeout: 10 seconds
Retries: 2 (confirm before alerting)
Regions: 1–2 locations (add more as you grow)
Alert policy: alert only after a failure to confirm (not a single error)

Why this works:

5-minute checks catch most significant downtimes without creating a constant stream of alerts.
A 10-second timeout is long enough to avoid false alarms from brief slowdowns, but short enough to catch failures.
Retries prevent one-off blips from waking you up in the middle of the night.

When to tighten the interval

Move to 1-minute checks when:

Your site is revenue-critical (for example, SaaS signups, e-commerce checkouts)
You’re running an important campaign, launch, or sales window
You’ve set up an on-call rotation for your support team or there’s someone specifically responsible for rapid response

How many regions should you monitor?

Beginner / local audience: 1 region is fine to start
National audience or a CDN-heavy site: 2 to 3 regions is safer
International / mission-critical: 3+ regions, plus built-in confirmation logic

Multi-region monitoring matters because what’s working for visitors in one region may not for visitors from another region (due to routing, CDN, DNS, or regional provider issues).

A note on “down” that’s actually just “slow”

Many incidents start as spikes in response-time before they become a full downtime. If your tool supports it, set a “slow response” threshold for your most critical page. But keep the threshold conservative to avoid false positives.

Alert basics and escalation (how to get notified without stressing yourself out)

Alerts are the pressure point where monitoring either succeeds or fails. The goal is straight-forward:

Alert the right person, through the right channel, while giving them enough context to take the appropriate action.

A starter alert setup (2 alerts that cover most needs)

Immediate alert: an email + Slack/Teams message for a confirmed downtime
Escalation alert: text message/phone call (possibly including a second person) if the downtime lasts more than 10 minutes

That’s all. There’s no need to over-complicate things when you’re staring out.

What your alert should include (basic context)

What’s down (URL/service name)
When the downtime began
Which regions detected it
Error type (for example, timeout, 5xx, DNS failure, SSL issue)
A link to the monitoring history

Escalation for different audiences

Solo site owner: email + text (or email + push notification)
Agency: Slack channel + tagged owner; notify client only after a prolonged incident
SaaS/e-commerce team: on-call rotation + escalation cascade + incident Slack channel

Reduce noise early (so you don’t start ignoring alerts)

Alert fatigue can seriously undermine you and your teams’ confidence in monitoring. If you’re getting lots of false alarms, consider tweaking the settings before you learn to tune out alerts altogether. Here’s a place to start: reduce false positives.

What to monitor first (homepage, sign-in, checkout, API)

A common mistake is to only monitor the homepage and assume you’re good. Instead, monitor what users need to have a positive experience on your site.

The minimum for most websites

Homepage (HTTP): confirms core reachability
Most important page (Keyword): confirms the site is actually working

Examples of important pages:

SaaS: sign-in page or dashboard landing page
E-commerce: product page or cart page
Lead gen or sales page: landing, pricing or booking page
Content site: a high-traffic or high-organic-search article

Next features to add as your site grows

Sign-in flow (keyword or multi-step if supported)
Checkout or payment confirmation page (non-destructive checks only)
Core API endpoints (a health endpoint, auth endpoint, or critical dependency)

As a rule of thumb, if a failure would generate a support ticket, refund, or lost lead, it warrants monitoring.

Tool selection checklist (with a basic starter stack)

A monitoring setup can perform well with only simple tools. Choose based on what you need, not because a service has the longest feature list.

Tool selection checklist

You can ask the following questions:

1) What do I actually need to monitor?

Uptime? (HTTP)
Is a specific page working? (keyword checks)
Multi-step flows? (sign-in/checkout)
An API?

2) How soon do I need to know?

5-minute checks are adequate for most sites
1-minute checks are better for revenue-critical sites

3) Who needs to be alerted—and how?

Email only?
Slack/Discord/Teams?
Text/escalation?
Webhooks to route into your system?

4) Do I need checks for multiple regions?

Local business: probably not
National/international: likely yes

5) Do I need reporting or a status page?

Agencies often need reports
SaaS/e-commerce often prefer a status page (public-facing or internal)

The basic starter stack

Start here:

1 uptime monitoring tool (HTTP + keyword checks)
2 alert channels (email + Slack/Teams OR email + SMS)
1 procedure doc (“If this happens, do this”)

A simple formula for calculating the cost of downtime

You can use this to justify the expense to the decision-makers in your organization. It’s accurate enough for them to make a decision.

Estimated downtime cost per hour ≈
(Revenue per hour) + (Leads per hour × value per lead) + (Support cost per hour) + (reputation risk)

If the numbers you plug into this formula don’t feel realistic, here’s an even simpler one:

Revenue per hour = monthly revenue ÷ 30 ÷ 24
Leads per hour = monthly leads ÷ 30 ÷ 24

Even smaller sites can be caught off guard by the realization that downtime costs aren’t just about sales. They’re also about lost trust and lost growth momentum.

Sample naming convention for monitoring

It’s extremely helpful to invest the time initially to establish a naming convention for your monitoring system. That way, the system can scale without becoming a mess. Consistent naming especially matters when you have more than a handful of monitors—which is often the case for agencies or multi-site operators.

Consider deploying a convention like this:

[Brand/Site] – [Environment] – [Check Type] – [Target]

Examples:

AcmeCo – Prod – HTTP – Homepage
AcmeCo – Prod – Keyword – Pricing Page
AcmeCo – Prod – HTTP – /login
AcmeCo – Prod – API – /v1/health

If you manage multiple sites, consider prefixing a client code or folder/group tag:

Client123 – AcmeCo – Prod – HTTP – Homepage

A clear, concise naming convention makes alerts readable and mitigates against mistakes in the heat of a downtime incident.

What should you set up today? A decision tree

If you’re starting from scratch, try this:

If you only do one thing:
✅ Create an HTTP monitor for your homepage that checks every 5 minutes with 2 retries.

If your site makes money or generates leads:
✅ Add a keyword monitor to your most important page.

If you have users signing in or checking out:
✅ Monitor /login and/or a key checkout step.

If you have a product that uses an API:
✅ Monitor a lightweight health endpoint plus one critical endpoint.

A way to take action right now

pick 1 site → set up 2 monitors + 2 alerts

Here’s a 15-minute action plan:

Pick the one site you care most about.
Set up two monitors:
- An HTTP monitor for the homepage
- A keyword monitor for your most important page
Configure two alerts:
- A main alert (email + Slack/Teams or email + SMS)
- An escalation if downtime lasts more than 10 minutes
Test the alert at least once, so you can begin to build trust in it.

If alerts get annoying, fix them using this guide: reduce false positives.
