Best monitoring modes

Visible textRaw HTMLCSS selector

WatchSimple is not a security scanner, but it can provide a simple early-warning layer for public pages that should stay stable.

What to watch

  • Homepage copy
  • Public notices
  • Policy pages
  • Important static pages

Setup guidance

  • Use visible text mode for pages where unexpected public text changes matter.
  • Use raw HTML mode for more sensitive structural change detection.
  • Use lower sensitivity for noisy pages and higher sensitivity for stable pages.

Example alerts

  • Homepage text changed outside a planned update window.
  • A public policy page gained unexpected wording.
  • A static page returned changed source content.

Start with one page.

First snapshots do not send alerts, so you can start monitoring without inbox noise.
