Meta account health audit

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

Run a full Meta Ads account health audit. Anchor everything in real blended performance, not Meta-attributed ROAS — pull blended CPA, new customer acquisition cost (nCAC), new customer contribution margin, and StoreHero MER as the ground truth. Then layer Meta campaign data on top.

Flag the top 5 issues ranked by estimated $ impact in the store's currency. Look across:

1. Campaign structure — Advantage+ Shopping vs. manual prospecting vs. retargeting split, and where over-attribution is masking real performance
2. Creative performance — fatigue signals (CTR decay, frequency >2.5, rising CPM), top vs. bottom 10% creative by StoreHero contribution margin per acquired customer (not Meta-reported ROAS)
3. Audience overlap and broadening — Advantage+ broadening into low-intent audiences, lookalike vs. broad performance gap when measured against StoreHero new customer CM
4. Account-level efficiency — frequency vs. CPA curve, optimal spend ceiling before efficiency collapses, day-of-week and time-of-day patterns
5. Tracking and signal quality — CAPI health, deduplication issues, EMQ score, missing purchase events vs. Shopify orders in StoreHero

For each issue: wasted spend over the last 30 days, expected blended CPA reduction if fixed, and the specific lever (creative refresh, audience consolidation, campaign restructure, signal repair).

End with a prioritised action list — top 3 fixes, ranked by $ impact, each with effort estimate (hours) and confidence level.

At the bottom of your answer, render an inline visual summary: KPI cards for total Meta spend, Meta blended CPA vs nCAC target, Meta-reported ROAS vs StoreHero contribution margin reality, and biggest single $ leak. Add a horizontal bar chart of top 5 issues by $ impact, colour-coded by traffic light. Place text commentary alongside the visuals. Use the Spend Advisor tool to suggest what to explore next.
