Monitor revenue-critical content, not just uptime

Sitewatch hashes your page's HTML content with SHA-256 to create a unique fingerprint. On each check, the new fingerprint is compared to the previous one. If they differ, the page structure changed. This catches everything from missing sections to template rendering failures.

Yes. You can set up to 5 watched phrases per page -- a price, a "30-day free trial" line, a phone number, a key CTA. Sitewatch only alerts when a phrase that was confirmed present then disappears, so it catches a botched edit dropping the words that matter without firing on every harmless content change. Fingerprinting watches the whole structure; watched phrases pinpoint the specific copy you can't afford to lose.

Sitewatch uses 2-of-3 retry confirmation before alerting. If the fingerprint changes consistently across retries, it is a real change. Transient variations from dynamic elements (timestamps, session tokens) are filtered out by the confirmation system.

No. Defacement detection is focused on security -- checking if a page was hacked or vandalized. Sitewatch content monitoring is focused on operational reliability: catching CMS errors, deploy regressions, CDN drift, and build failures that change your pages unintentionally.

After deploying intentional changes, trigger an on-demand check from the dashboard. This establishes the new fingerprint as the baseline. The 2-of-3 confirmation system also helps -- a one-time change during deploy won't trigger alerts if the page stabilizes.

Sitewatch fetches pages over HTTP and analyzes the HTML response. It checks every referenced script and asset for availability and correct delivery. For content fingerprinting, it hashes the server-rendered HTML, which captures the page structure as delivered to browsers.
