Ecommerce price changes
Detect when a product price, discount badge, or checkout flow is modified before customers notice a discrepancy.
Page Change Detection
Know the instant any webpage changes.
WatchPage's page change detection software monitors CSS-selected elements on any URL. When the content changes, you get an alert with the old and new values — no manual checking, no missed updates.
Why page change detection matters
Websites change silently. Prices drop without announcement. Stock labels flip. Competitor offers update overnight. Without automated change detection, your team only finds out when a customer complains or a campaign underperforms.
Competitor offer updates
Get alerted when a competitor changes their pricing page, hero copy, or feature list so you can respond the same day.
Regulatory and compliance pages
Track legal, terms-of-service, or policy pages for unexpected edits that require internal review.
Campaign landing pages
Ensure paid traffic destinations stay live and unchanged. Know immediately if a CTA or form disappears.
How WatchPage detects changes
Selector-based monitoring: Instead of diffing entire HTML pages, WatchPage watches the specific element you care about — a price span, a button label, a stock indicator. This eliminates noise from ads, navigation, and layout shifts.
Baseline comparison: On first run, WatchPage records the current value as a baseline. Every subsequent check compares against this baseline. If the value changes, an alert fires immediately.
Full change history: Every change event is stored with a timestamp, previous value, and new value. Your team can audit the exact sequence of changes on any monitor.
