What is web scraping change tracking?
TL;DR
Change tracking scrapes pages periodically and compares results. When data changes—prices, availability, content—it triggers alerts.
What is change tracking?
Automated systems capture page content at intervals, compare against previous versions, and notify you of differences.
Common use cases
- Price monitoring: Track competitor pricing changes
- Stock alerts: Detect when items become available
- Content updates: Monitor news or regulatory changes
- Job postings: Watch for new positions
How it works
- Initial scrape establishes baseline
- Scheduled scrapes capture current state
- Comparison identifies differences
- Changes trigger configured actions
Firecrawl's changeTracking format returns structured diffs automatically—no custom comparison logic needed.
Key Takeaways
Change tracking transforms scraping from one-time extraction to continuous monitoring for real-time market awareness.
