# Campaign #19: Standard Shopping Margin Segmentation (Multi-Category E-Commerce)

## Platform & Benchmark Profile
- **Platform:** Google Ads (Google)
- **Audited Spend Benchmark:** $1,120,000
- **Delivered Traffic:** 412,000 clicks
- **Average Cost:** $2.72 CPC
- **Production Results:** +27% Gross Margin Lift
- **Key Efficiency Metric:** Zero Volume Collapse

## The Operational Failure Mode
Increasing Target ROAS by 20% caused impression volume to collapse by 68%. Pacing adjustments in 5% increments every 7 days and segmenting by margin labels lifted gross profit by 27%.

## The Code-First Execution Fix
Custom label margin tiering (High/Medium/Low), conservative 5% bi-weekly tROAS stepping, negative search query routing.
