Website change detection is the automated process of monitoring web pages for content modifications and alerting you when changes occur. It's a crucial tool for businesses, researchers, and individuals who need to stay informed about updates across the web.
How Does Website Change Detection Work?
At its core, website change detection follows a simple process:
- Fetch - The tool retrieves the webpage content at regular intervals
- Compare - It compares the new content with the previous version
- Detect - Algorithms identify meaningful changes
- Notify - You receive an alert when changes are detected
Technical Note
Modern change detection tools like Drifter use smart algorithms to filter out noise like timestamps, dynamic ads, and random elements that change on every page load.

|---|---|---|
| Time per check | 2-5 minutes | 0 minutes |
| Daily time | 20-50 minutes | 0 minutes |
| Monthly time | 10-25 hours | 0 hours |
Never Miss Changes
Automated monitoring ensures you catch every change, even if it happens at 3 AM on a Sunday.
