Monitoring
Website change monitoring for specific data, not just pixels
Change monitoring becomes useful when you define what counts as a meaningful update: a price, status, row, text field, link, or structured value.
Select stable targets
Prefer semantic fields or well-defined page regions over broad visual comparisons when you need structured alerts.
Set a useful interval
Checking every minute is wasteful if the source changes weekly. The right frequency follows the business decision.
Filter noise
Timestamp banners, rotating ads, and personalization can create false positives. Exclude or ignore them where possible.
Record context
Store the old value, new value, source URL, and time so alerts are actionable.
