Example Output
Example 1: Campaign Performance Analysis
Input: Monthly ACoS data for 5 Amazon PPC campaigns
Output:
- Campaign A (ACoS 28%): High performer → recommend 15% spend increase
- Campaign C (ACoS 52%): Underperformer → recommend keyword pruning and bid reduction on low-converting terms
- Forecast: Reallocating $500/month from C to A could increase overall ROAS by 12% ($2,400 annual impact)
Example 2: Budget Reallocation Strategy
Input: Q3 performance summary across 3 marketplace channels
Output:
- Amazon (ROAS 3.2x) → Increase budget 20%
- Walmart (ROAS 2.1x) → Maintain current
- eBay (ROAS 1.5x) → Reduce spend 30%, reallocate to Amazon
- Projected impact: +18% blended ROAS within 30 days
Example 3: Bid Strategy Adjustment
Input: Top 50 keywords with conversion data
Output: Bid recommendations ranked by priority—decrease bids on 12 low-converting keywords (save $800/month), increase bids on 8 high-converting keywords with volume potential (add $600/month)
