E-commerce monitoring

Your Checkout Is Up. But Is It Actually Working?

A broken payment script doesn't return a 500 error — it silently fails while your uptime monitor says everything is fine. Sitewatch monitors the assets that power your checkout flow, product pages, and cart functionality. When a CDN drops your payment JS or a deploy breaks your product images, you know immediately.

  • Monitor checkout flow health — scripts, stylesheets, payment embeds
  • Catch broken payment scripts before they cost you revenue
  • Validate product page assets — images, pricing scripts, review widgets

Silent revenue killers

E-commerce failures uptime tools miss

Payment script failures

Critical

Stripe.js, PayPal SDK, or your payment processor's script 404s after a CDN change. The checkout page loads but the payment form is invisible. No errors in your uptime tool.

Product image breakage

Critical

A CDN purge or image optimization service fails. Product pages load with broken thumbnails. Customers can't see what they're buying.

Cart JS bundle failure

Critical

A deploy breaks the cart JavaScript bundle. Add-to-cart buttons stop working. The page looks normal but nothing is clickable.

Redirect chain on checkout

Moderate

A misconfigured redirect sends checkout traffic through 3+ hops before landing. Mobile users drop off. Conversion tanks.

Review widget failure

Moderate

Your third-party review widget (Trustpilot, Yotpo, Judge.me) fails to load. Social proof disappears from product pages.

Pricing display errors

Critical

A broken stylesheet or JS dependency causes pricing to render incorrectly — wrong currency, missing decimals, or invisible prices.
