Рекомендации по оптимизации кампаний

INPUT

• Campaign-level performance data, date range: last 7 days
• Campaign budget and configuration data
• Learning phase status: determined by campaign age (see GUARD)

CONFIG (user-configurable)

Key	Default	Description
TARGET_CPA	—	User-defined target cost per acquisition
FREQ_THRESHOLD	3	Alert if frequency exceeds this
CTR_DECLINE_PCT	15	Alert if CTR drops below 7-day avg by this %
CPA_RISE_PCT	20	Alert if CPA rises above 7-day avg by this %
ZERO_CONV_MULTIPLIER	2	Shutdown trigger: spend > daily_budget × this with 0 conversions
SHUTDOWN_CPA_MULTIPLIER	2	Shutdown if CPA exceeds this × TARGET_CPA for 3+ days
BUDGET_INCREASE_CPA_IMPROVEMENT	20%	CPA must be this much below target to qualify for budget increase

---

PROCESS

Step 1 — Classify Each Campaign

Evaluate all criteria below for each active campaign:

Shutdown criteria (evaluate in this priority order):

1. Spend > daily_budget × ZERO_CONV_MULTIPLIER with 0 conversions → flag as SHUTDOWN (regardless of age/learning phase)
2. CPA > SHUTDOWN_CPA_MULTIPLIER × TARGET_CPA for 3+ consecutive days AND campaign has exited learning phase AND active 7+ days → flag as SHUTDOWN
3. Frequency > FREQ_THRESHOLD AND CTR declined > CTR_DECLINE_PCT% vs 7-day average AND CPA rose > CPA_RISE_PCT% vs 7-day average AND campaign has exited learning phase AND active 7+ days → flag as SHUTDOWN

Budget increase criteria (ALL must be met):

• Campaign has exited learning phase AND active 7+ days
• CPA below TARGET_CPA by > BUDGET_INCREASE_CPA_IMPROVEMENT for 3 consecutive days
• Current spend > 80% of daily budget
• Frequency < 2.5
• Not flagged by any shutdown criterion above

Step 2 — Conflict Resolution

If a campaign meets both shutdown AND budget increase criteria → suppress budget increase, output only shutdown recommendation.

Step 3 — Build Recommendation List

For each recommendation output:

• Item ID (auto-increment)
• Campaign ID and name
• Criteria met (which rule triggered)
• Learning phase status (learning / exited)
• Current spend and key metrics
• Recommended action (pause / reduce budget / increase budget)

OUTPUT

📋 RECOMMENDATION LIST

#	Campaign ID	Campaign Name	Criteria Met	Learning Phase	Current Spend	Action

If no campaigns meet any criteria: output ✅ No campaigns require optimization action today.

GUARD

• Learning phase check: a campaign is considered "in learning phase" until it has spent ≥ 50 × daily_budget OR 7 days have passed (whichever comes first)
• CPA-related criteria are evaluated against TARGET_CPA — report CPA: N/A if target not configured
• If insufficient data to evaluate a criterion (e.g., < 7 days of data): skip that criterion, do not flag
• This prompt outputs recommendations only — no automatic or semi-automatic execution is performed
