Screenshot Monitoring
See when a page changes visually — defacement, broken layout, a new banner.
Each check captures a screenshot of the page and compares it with the previous one pixel by pixel. Changes that status codes and keywords miss show up here.
What it detects
- Visual changes above the threshold you set (5% by default)
- Redesigned or resized pages, always reported as a full change
- Error pages that replace your content
