How to monitor a website

Website monitoring means automatically checking whether your website is online, responding correctly, and usable for visitors.

It is not enough to open your homepage once in a while and assume everything works. Websites break because of failed deployments, hosting issues, DNS problems, expired SSL certificates, slow databases, CDN failures, broken frontend builds, and third-party services.

A monitoring setup helps you detect these problems early, get alerted, and understand what failed.

This guide explains how to monitor a website in a practical way: what pages to check, what settings matter, which alerts to configure, and how to avoid false alarms.

What should website monitoring check?

A good website monitor should not only ask:

Does the server respond?

It should ask:

Is this page working the way users expect?

That can include several checks:

  • HTTP status code;

  • response time;

  • timeout;

  • page content;

  • SSL certificate validity;

  • DNS resolution;

  • availability from multiple regions.

For a basic website, checking the homepage may be enough to start. For a SaaS product, ecommerce store, or business website, you should monitor more than one page.

Step 1: Start with your most important pages

Do not monitor every page on day one. Start with the pages where downtime would hurt the most.

For a SaaS product, monitor:

  • homepage;

  • login page;

  • signup page;

  • pricing page;

  • dashboard;

  • API health endpoint;

  • checkout or billing page.

For a business website, monitor:

  • homepage;

  • contact page;

  • booking page;

  • lead form page;

  • main service pages;

  • paid ad landing pages.

For an e-commerce website, monitor:

  • homepage;

  • product pages;

  • cart page;

  • checkout page;

  • payment confirmation page.

The rule is simple: if a broken page can cost you leads, signups, payments, or trust, it should be monitored.

Step 2: Define what “working” means

A common mistake is treating any response as success.

That is weak monitoring.

A website can return 200 OK and still be broken. It may show a blank page, an error message, an empty React app, a broken CMS template, or the wrong content.

Define success clearly.

Examples:

Homepage should return HTTP 200.

Login page should return HTTP 200 and contain “Sign in”.

Pricing page should return HTTP 200 and contain “Pricing”.

API health endpoint should return HTTP 200 and contain {"status":"ok"}.

This is where status code checks and keyword checks work together.

Status code monitoring tells you whether the server responded correctly. Keyword monitoring tells you whether the expected content is actually present.

Step 3: Configure the expected HTTP status code

HTTP status codes are one of the simplest signals for website health.

Common examples:

Status code

Meaning

200

OK

301/302

Redirect

401/403

Unauthorized or forbidden

404

Not found

500

Internal server error

502

Bad gateway

503

Service unavailable

504

Gateway timeout

For most public pages, the expected result is 200 OK

But some URLs are expected to redirect. For example http://example.com may redirect to https://www.example.com

In that case, a 301 or 302 may be valid.

The important part is that you decide what is expected. Do not accept every response as healthy.

Step 4: Add keyword monitoring for important pages

Keyword monitoring checks whether a page contains expected text.

This is useful because many website failures are not visible through status codes alone.

Example:

The homepage returns 200 OK, but the frontend bundle failed and the page is blank.

A simple HTTP status check may say the page is fine. A keyword check can catch the problem.

Good keyword examples:

Start monitoring

Sign in

Pricing

Contact us

Book a demo

Bad keyword examples:

random testimonial text

rotating banner text

dynamic user-specific text

temporary promotion text

Use stable text that should always appear on the page.

This directly maps to an Uptimetry feature: HTTP check plus expected keyword/content validation.

Step 5: Choose the right check interval

The check interval is how often your monitor runs.

A practical setup:

Page type

Suggested interval

API health endpoint

1 minute

Login or signup page

1–3 minutes

Checkout or billing page

1–3 minutes

Homepage

5 minutes

Marketing landing page

5 minutes

Blog or non-critical page

10–30 minutes

Shorter intervals detect downtime faster. Longer intervals are acceptable for less important pages.

For most small SaaS products and business websites, checking key pages every 1–5 minutes is enough to start.

Step 6: Configure alerts where you actually respond

Monitoring without alerts is just passive data collection.

Useful alert channels include:

  • Slack;

  • Discord;

  • Telegram;

  • webhooks.

For a solo founder or small team, Discord or Telegram is often enough. For a bigger team, Slack or webhook-based workflows may fit better.

Step 10: Review incident history

Website monitoring is not only about instant alerts. It should also help you understand reliability over time.

Incident history helps answer:

  • How often does the website go down?

  • Which pages fail most often?

  • How long do incidents last?

  • Do failures happen after deployments?

  • Is response time getting worse?

This information helps you improve your website instead of only reacting to failures.

Simple website monitoring setup

For a small SaaS product, start with this:

Monitor

Check

Interval

Homepage

HTTP 200 + keyword

5 minutes

Login page

HTTP 200 + keyword

1–3 minutes

Pricing page

HTTP 200 + keyword

5 minutes

API health endpoint

HTTP 200 + expected response

1 minute

Checkout page

HTTP 200 + keyword

1–3 minutes

This is simple enough to maintain, but strong enough to catch serious issues.

Common mistakes

Monitoring only the homepage

Your homepage may work while login, checkout, or API endpoints are broken.

Checking only HTTP status

200 OK does not always mean the page is usable.

Sending alerts to a channel nobody checks

If nobody sees the alert, the monitor is almost useless.

Final thoughts

Website monitoring is not complicated. The hard part is choosing what matters.

Start with your most important pages. Define what a successful response looks like. Use status code checks, keyword checks, sensible intervals, retries, multi-region checks, and useful alerts.

The goal is not to collect random monitoring data.

The goal is to know when your website breaks, understand what failed, and respond before more users are affected.
