Alert Severity Rules for Small Business Website Monitoring

Too many teams treat every alert as an emergency and then ignore the next one. Severity rules fix this by matching response effort to business impact.

Clear tiers reduce burnout and improve real incident response speed.

Simple 4-level severity model

• SEV1: Revenue path down (checkout, booking, lead form fully broken)
• SEV2: Major degradation (high latency, partial failures on core pages)
• SEV3: Non-critical failure (blog pages, low-traffic assets)
• SEV4: Informational signals (single timeout, warning trends)

Define response targets per severity

Each level should have an owner, response time, and escalation path. For example, SEV1 response in 5 minutes, SEV2 in 30 minutes, and SEV3 during business hours.

Alert channels by severity

Route SEV1 to SMS plus phone escalation. Keep lower levels in chat or email to avoid alert fatigue.

Channel design is as important as threshold design.

Write conditions in business language

"Checkout confirmation page unavailable for 2 consecutive checks" is better than "HTTP monitor failed." Clarity speeds action.

Review and tune monthly

Incident patterns change with traffic and releases. Run a monthly severity review and adjust thresholds based on false positives and missed incidents.
