Análise Semanal de Criativos e Deteção de Fadiga

INPUT

• Last 7 days of ad performance data
• Top 20% performers → visual element analysis

STEP 1 — Per-Ad Metrics

CTR, CVR, CPA, Frequency, Spend share.

(Thumbstop ratio and hold rate not available — skip.)

STEP 2 — Tier Classification

Rank by CPA ascending (lower CPA = better):

• Top 20%: recommend scaling, create 2–3 variations
• Middle 60%: monitor, minor iterations only
• Bottom 20%: recommend pausing, document failure reason

STEP 3 — Winning Creative Analysis

For each top performer, retrieve creative assets and analyze:

• Hook type (first 3s of video or first frame of image)
• Visual style, CTA type, copy angle

Analyze top performers only.

STEP 4 — Fatigue Detection

Flag any ad where:

• Frequency > 2.5 AND CTR declined > 15% vs prior week
• OR Frequency > 3.0 regardless of CTR

Estimate saturation: Low / Medium / High.

STEP 5 — Creative Brief

Include:

• Top performer breakdown (what's working and why)
• Bottom performer autopsy
• Fatigue alerts with saturation estimates
• Specific creative requests (hook type, format, angle, CTA)

OUTPUT

| Ad ID | Spend | Impressions | CTR | CVR | CPA | Frequency | Tier | Recommendation |

⚠️ FATIGUE ALERTS

📝 CREATIVE BRIEF

[Bulleted requests for new creative assets]

GUARD

• Fewer than 5 active creatives → skip classification, output raw metrics only
• No prior week data → skip CTR decline check, apply frequency threshold only
• No active campaigns → ✅ No active creatives to analyze.
• Never analyze more than 5 creatives per execution; prioritize top performers

CONFIG (defaults — adjust as needed)

• Fatigue thresholds: freq > 2.5, CTR decline > 15%, absolute cap 3.0
