Content Monitoring
Monitor revenue-critical content, not just uptime
A CMS update removes your pricing section. A CDN purge serves stale content. A deploy changes page structure in ways you didn't intend. Sitewatch fingerprints your pages and detects structural changes before they cost you revenue.
- SHA-256 page fingerprinting detects structural changes
- Catch CMS updates, CDN purges, and deploy regressions
- Evidence-rich alerts show exactly what changed

Beyond defacement detection
Your page content is a revenue asset. Monitor it like one.
SHA-256 page fingerprinting
Every page's HTML is hashed with SHA-256. When the structure changes unexpectedly -- a missing section, a rearranged layout, a stripped CTA -- Sitewatch flags it.
Deploy regression detection
A code deploy changes your landing page in ways you didn't intend. Maybe a component disappeared, or a build error stripped critical content. Fingerprinting catches it.
CDN and cache drift
CDN purges gone wrong, stale cache served to some regions, edge nodes returning outdated content. Sitewatch detects when your pages diverge from what you expect.
CMS change detection
A content editor removes a section, changes pricing copy, or accidentally publishes a draft. Fingerprinting detects the structural change before it impacts conversions.
Non-HTML response detection
Your URL suddenly serves JSON, XML, or a file download instead of a webpage. Sitewatch catches this immediately -- a failure mode that uptime tools are blind to.
Revenue-critical page protection
Pricing pages, landing pages, checkout flows -- the pages that directly generate revenue deserve more than a simple uptime check.

Content change types
How page content breaks without anyone noticing
Structural changes
- Page HTML structure changes after deploys or CMS updates
- Missing sections, stripped CTAs, or rearranged layouts
- Build errors that produce incomplete or empty pages
- Template rendering failures that output raw markup
Content delivery issues
- CDN serving stale or outdated content to specific regions
- URLs serving non-HTML responses (JSON, XML, downloads)
- Redirect misconfiguration sending users to wrong pages
- Host drift causing the domain to resolve to an unexpected server
How it works
How Sitewatch monitors page content
Fetch your page
Sitewatch fetches the page over HTTP and retrieves the complete HTML response, the same content a browser would receive.
Generate SHA-256 fingerprint
The page HTML is hashed with SHA-256 to create a unique fingerprint. This baseline is stored and compared on every subsequent check.
Detect changes
When the fingerprint changes, Sitewatch flags it. Combined with asset verification (status codes + MIME types), you get a complete picture of page health.
Alert with context
Confirmed changes trigger alerts across your configured channels. You see which page changed, when, and can trigger an on-demand check to establish the new baseline after intentional updates.

Beyond keyword matching
Content monitoring that actually works
| Feature | String-matching tools | Sitewatch |
|---|---|---|
| Detection method | Search for specific text strings | SHA-256 fingerprint of entire page structure |
| JS-rendered content | Invisible -- only sees raw HTML | Fetches what servers deliver to browsers |
| Deploy regressions | Only if watched string disappears | Any structural change detected |
| Asset verification | Not included | Every script, stylesheet, image checked |
| False positives | High -- every minor text edit alerts | 2-of-3 confirmation, structural focus |

FAQ
Frequently asked questions
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.
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.
