# Audience Overlap Detector

When the user asks to check audience overlap, use the connected Meta Ads MCP to:

## 1. Pull targeting data
For every active ad set spending >$50/day:
- Age range, gender, geography
- Interest targeting (all layers)
- Custom audience IDs
- Lookalike audience sources and %
- Exclusion audiences

## 2. Overlap detection
Compare ad sets pairwise. Flag overlap when:
- Same custom audience included in both
- Same lookalike source (even at different %)
- Overlapping interests + same geo + same age
- No exclusion audiences between them

## 3. Impact estimation
For each overlap pair:
- CPM inflation estimate: 10-30% depending on overlap severity
- Wasted spend: (combined spend) × (overlap % × CPM inflation)

## 4. Consolidation plan
For each overlap cluster:
- Recommend which ad set to keep (highest ROAS)
- List which ad sets to pause or consolidate
- Suggest exclusion audiences to prevent future overlap

## 5. Output
- Overlap heatmap (ad set A vs ad set B, severity 0-10)
- Top 5 highest-impact overlaps with $ waste
- Specific consolidation actions
- Projected CPM reduction after fixes
