E-commerce Uptime Monitoring

Every minute your store is down costs sales. Monitor your entire checkout flow and get alerted instantly when something breaks.

For e-commerce, downtime has an immediate cost: lost revenue. Studies show the average e-commerce site loses thousands per minute of downtime. But even worse than the immediate loss is the long-term damage—customers who hit an error during checkout rarely come back.

What to monitor on your e-commerce site

Storefront and product pages

Your homepage and product pages are how customers find and browse your products. Monitor response times and availability to catch issues before they impact browsing experience.

Cart and checkout flow

The checkout flow is where money changes hands. A broken checkout is an emergency. Monitor each step: add to cart, cart page, shipping selection, payment page, and order confirmation.

Payment gateway integrations

Your payment processor (Stripe, PayPal, Square, etc.) can have issues that break your checkout even when your site is "up." Monitor your payment integration endpoints directly.

Inventory and fulfillment systems

If your inventory sync breaks, you might sell items you don't have. Use heartbeat monitoring to ensure inventory sync jobs and order processing run on schedule.

Third-party services

Reviews, search, recommendations, shipping calculators—modern e-commerce sites depend on many services. Monitor the ones that are critical to purchase decisions.

E-commerce monitoring best practices

Use keyword monitoring for checkout errors

Don't just check if pages load—verify they show the right content. Use keyword monitoring to detect error messages like "payment failed" or "out of stock" on pages where they shouldn't appear.

  • Check frequently – Use 1-minute intervals for critical pages like checkout
  • Monitor from multiple locations – Customers shop from everywhere; check from regions where you have customers
  • Set up escalation – Checkout issues should wake someone up; blog issues can wait until morning
  • Track response times – Slow pages kill conversion rates even when they're technically "up"

Use case: Out-of-stock monitoring

Beyond uptime, you can use keyword monitoring to track product availability. Set up monitors that alert you when key products show "out of stock"—or when they come back in stock at competitors. See our out-of-stock alerts guide for details.

FAQ

The cost depends on your revenue, but studies show the average e-commerce site loses $5,600 per minute of downtime. Even small stores can lose hundreds per hour, plus the hidden costs of damaged customer trust.

At minimum: homepage, product pages, cart, and checkout. Also monitor payment gateways, inventory systems, and critical third-party services.

For e-commerce, faster is better. With 1-minute check intervals, you can detect issues within 1-2 minutes and often resolve them before customers notice significant impact.
