Google Update Correlation
When volatility spikes:
- Check Google Search Status Dashboard
- Cross-reference with industry volatility tools (SEMrush Sensor, Moz MozCast)
- Identify pattern: site-wide vs topical vs page-level
- If confirmed update: document affected pages, defer changes 2-4 weeks until stable

Technical Health Monitoring
Index Coverage Tracking
| Signal | Threshold | Severity | |
|---|---|---|---|
| Indexed pages drop >10% weekly | 🟠 High | Check robots.txt, noindex, server errors | |
| Indexed pages drop >20% | 🔴 Critical | Immediate investigation | |
| "Excluded" pages increase >20% | 🟡 Medium | Review exclusion reasons | |
| New crawl errors spike | 🟠 High | Fix 5xx, check redirects |
CWV Degradation Detection
| Metric | Warning | Critical | |
|---|---|---|---|

| INP | >200ms (was passing) | >500ms | |
| CLS | >0.1 (was passing) | >0.25 |
Trigger re-audit via seo-performance when any CWV degrades from "good" to "needs improvement".
Security Monitoring

| Day 14 | Ranking movement | Climbing | Stuck or declining | |
| Day 30 | Stable position | Top 20 | Outside top 50 | |

Content Decay Detection
- Traffic decline: Organic sessions drop ≥20% for 3 consecutive weeks
