Why uptime matters

In e-commerce, every minute of downtime is measurable in lost orders. A 60-second outage on a peak Saturday afternoon is not an inconvenience — it is hundreds or thousands of pounds in revenue that walked away to a competitor. And yet most retailers still run on a single uptime check that only catches full outages, missing the partial failures that drain conversions all day.

Modern commerce stacks fail in subtle ways: a payment gateway that times out only on Visa cards, a CDN that serves stale product images, a cart that returns 200 OK but silently drops items above £100. E-commerce uptime monitoring needs to look at the customer journey end-to-end, not just whether the homepage loads.

What goes wrong

Monitors that matter

These are the Uptrue monitor types that map most directly to the failures above. Each links to a full setup guide.

Keyword monitoring →

Verify "Add to cart", "Checkout", "Place order" or any other critical button text is present on every check. Catches the broken-page-with-200-OK failure that destroys sales.

Response time monitoring →

Slow checkout is abandoned checkout. Alert when TTFB on /cart or /checkout exceeds your conversion threshold.

SSL certificate monitoring →

A browser SSL warning on checkout instantly drops conversion to zero. Get alerted 30, 14 and 3 days before expiry on every subdomain.

Redirect chain monitoring →

Excessive redirects after a CMS migration drop pages from Google index and slow every visitor. Catch chains over 3 hops or broken final destinations.

Security headers monitoring →

Headers like CSP and X-Frame-Options often disappear after CDN reconfiguration — opening you to compliance issues and Magecart-style attacks.

Cookie consent monitoring →

A missing consent banner is a GDPR/ePrivacy violation under European law. Catch it within minutes of a regression.

Frequently asked questions

How is e-commerce uptime monitoring different from a basic uptime check?
A basic uptime check tells you the homepage loads. E-commerce uptime monitoring tells you whether the cart, checkout, payment gateway and post-purchase flow actually work. A retailer can have 100% homepage uptime and still lose 20% of conversions to a broken cart endpoint that returns 200 OK with an error in the body.
Do you monitor Shopify, WooCommerce, BigCommerce stores?
Yes — Uptrue monitors any public URL regardless of the e-commerce platform. We additionally publish a WordPress plugin (free, on WordPress.org) that runs internal WooCommerce checks: payment gateway health, rogue admin accounts, plugin CVE detection, and order volume anomalies. The browser-side monitors and the plugin are complementary.
Can we run a smoke test of the full checkout flow?
For a full multi-step browser-based checkout test, you need browser automation (synthetic transaction monitoring) which is on the V1.5 roadmap. For now, the recommended pattern is to monitor each step independently: cart endpoint, checkout endpoint, /thank-you page presence after order. This catches 90% of real failures without the cost of full synthetic monitoring.
How do we handle Black Friday or peak campaign traffic?
Increase check frequency on critical paths (cart, checkout, payment) to 30 seconds in advance of the peak. Set tighter response-time thresholds. Connect alerts to Slack and a paging tool. Pre-publish a status page so customers see "we know" instead of refreshing in frustration. The Free plan includes 3 monitors — most retailers upgrade temporarily during peak season.
Will monitoring add load to our checkout?
Negligible. A monitor check is a single HTTP request from the edge — comparable to one bot crawl per check interval. At a 1-minute interval that is 1,440 requests per day from Uptrue, against typical checkout traffic of tens of thousands per day. Use HEAD requests or a dedicated /__health endpoint if you want zero-cost checks.
What about monitoring the payment gateway itself?
Use API Endpoint monitoring against your gateway test endpoint. Configure assertions on response status and body content (e.g. "status: \"success\"" must appear). Use Response Time monitoring with tight thresholds — gateway slowness is often the first sign of an upstream incident at Stripe, Adyen, or Braintree.
