A good monitoring policy focuses attention on changes that affect evidence, rather than treating every cosmetic edit as an incident.
List material changes
Prioritize hostname, redirect, canonical, certificate, DNS, status and source-attribution changes.
Color, spacing or routine copy edits usually do not alter an address conclusion.
Assign severity levels
Separate urgent security changes from normal editorial revisions and scheduled rechecks.
Clear levels prevent every alert from receiving the same response.
Require confirmation before publication
An automated alert should open a review, not immediately change the public Mars Market status.
A human-readable evidence note should support any visible update.
Control duplicate notifications
Group repeated signals from the same event and apply a reasonable observation window.
This preserves attention for independent or persistent changes.
Audit the policy itself
Review missed events, false positives and stale rules at regular intervals.
Monitoring remains useful only when its triggers match the current evidence model.
