Surveillance quotidienne des performances et du pacing

CONTEXT

Monitor active campaigns for performance anomalies and budget pacing issues. Run this check daily, weekly, or monthly based on your configured schedule.

CONFIG

Parameter	Default	Description
Analysis Type	daily	How often this runs: daily, weekly, or monthly
CPM Spike Alert	30%	Flag if CPM exceeds 7-day average by this much
CTR Drop Alert	20%	Flag if CTR drops below 7-day average by this much
CPA Breakeven	—	Alert if CPA exceeds this value
Zero-Conv Spend Threshold	2× daily budget	Flag if spend exceeds this with zero conversions
Under-pace Threshold	45% at 50% elapsed / 56% at 80% elapsed	Flag if expected spend not reached
Over-pace Threshold	110%	Flag if spend exceeds this vs expected

---

PROCESS

Learning Phase Check

For each campaign, determine whether it is still in the learning phase:

• Still learning: spend is less than 50× the daily budget AND it has been less than 7 days since launch
• Exited learning: either condition has been met

Learning-phase campaigns are excluded from CPA anomaly checks, but always included in pacing analysis.

Anomaly Detection

Compare current performance against 7-day averages. Flag the following:

• CPM spike: current CPM is elevated beyond the configured threshold vs its 7-day average
• CTR drop: current CTR has declined beyond the configured threshold vs its 7-day average
• CPA above breakeven: CPA has exceeded the breakeven threshold
• Zero-conversion overspend: no conversions recorded and spend has exceeded the configured multiplier of daily budget

Budget Pacing

For each campaign, calculate expected spend based on time elapsed and compare against actual spend.

Time Elapsed	Expected Spend	Flag if Under	Flag if Over
50% of day	50% of daily budget	< 45% = under-paced	> 110% = over-paced
80% of day	80% of daily budget	< 56% = under-paced	> 110% = over-paced

Severity

• Critical: multiple anomalies detected, or zero-conversion overspend
• Warning: a single anomaly

---

OUTPUT

If no active campaigns: ✅ No active campaigns to analyze.

Otherwise output:

🚨 ALERT SUMMARY

📊 PACING STATUS

• Critical: show recommended action only
• Warning: include suspected cause and recommended action

NOTES

• CPA checks are skipped when conversion data is unavailable — report CPA: N/A
• Always include learning-phase campaigns in pacing analysis
• If data is insufficient to evaluate any metric, skip that check without flagging
