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
CriticalStripe.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
CriticalA 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
CriticalA deploy breaks the cart JavaScript bundle. Add-to-cart buttons stop working. The page looks normal but nothing is clickable.
Redirect chain on checkout
ModerateA misconfigured redirect sends checkout traffic through 3+ hops before landing. Mobile users drop off. Conversion tanks.
Review widget failure
ModerateYour third-party review widget (Trustpilot, Yotpo, Judge.me) fails to load. Social proof disappears from product pages.
Pricing display errors
CriticalA broken stylesheet or JS dependency causes pricing to render incorrectly — wrong currency, missing decimals, or invisible prices.

E-commerce monitoring FAQ
Sitewatch monitors any website regardless of platform. We automatically detect Shopify, WooCommerce, Magento, BigCommerce, and custom builds — then tailor root cause diagnosis and fix playbooks to your specific platform.
Yes. Add your checkout URL and key product pages as monitored pages. Sitewatch checks every linked asset — scripts, stylesheets, images, and embedded content — on each page independently.
With deploy hooks, within minutes of a deploy. With scheduled monitoring, within 5–30 minutes based on your chosen check interval. All plans let you configure the frequency — Pro goes as low as every 5 minutes.
No. Sitewatch monitors from external servers — it doesn't install anything on your store and doesn't add any client-side JavaScript. Zero impact on page load times.
