Find Meta Ads waste

Use the StoreHero MCP to do the following analysis. Always anchor the answer in real StoreHero data, not platform-reported metrics.

Find Meta Ads waste over the last 30 days. Anchor everything in real blended performance — pull blended CPA, new customer acquisition cost (nCAC), and new customer contribution margin as the ground truth. Then identify Meta spend that isn't paying back when measured against StoreHero data, not Meta-attributed ROAS (which over-reports on Advantage+ and view-through).

Look for:

1. Over-attribution gap — campaigns where Meta-reported ROAS looks healthy (>2x) but StoreHero blended CPA exceeds nCAC ceiling. Show the size of the gap in $
2. Creative fatigue — ads with frequency >2.5, CTR decay >25% week-over-week, or rising CPM with flat conversions. Spend allocated to fatigued creative last 30 days
3. Advantage+ broadening — Advantage+ Shopping campaigns that have widened audiences and now pull lower-intent traffic, with blended new customer CM dropping below threshold
4. Retargeting overlap — retargeting campaigns claiming conversions that prospecting already paid for. Show estimated cannibalisation $
5. Audience underperformers — interest-based, lookalike, or custom audiences with blended CPA above nCAC ceiling, with min 20 conversions for significance
6. Placement leak — placements (Audience Network, Reels, Right Column) eating spend with disproportionately weak blended performance

For each waste source: $ wasted last 30 days, projected $ saved if action taken, and the exact action (creative pause, audience consolidation, placement exclusion, campaign restructure, frequency cap).

End with a single number: total $ wasted last 30 days that could be recovered with this week's actions.

At the bottom of your answer, render an inline visual summary: a single big KPI card showing total recoverable $ over 30d, plus a horizontal bar chart of waste sources ranked by $ impact, colour-coded by ease-of-fix. Add one extra card showing the gap between Meta-reported ROAS and StoreHero blended reality. Place text commentary alongside the visuals. Use the Spend Advisor tool to suggest what to explore next.
