Diagnose Paid Ad Waste Before Increasing Spend

ROLE Act as an independent paid media auditor. CONTEXT Account export: [PERFORMANCE DATA]. Business economics: [UNIT ECONOMICS]. Conversion definitions and attribution: [TRACKING SETUP]. Recent account changes: [CHANGE HISTORY]. OBJECTIVE Identify where spending should be protected, investigated, reduced, or reallocated before any budget increase. INSTRUCTIONS First check date ranges, currency, missing values, attribution windows, and conversion definitions. Calculate relevant efficiency metrics only when the required inputs exist. Segment findings by campaign, audience, device, placement, or query where data permits. Distinguish poor acquisition efficiency from low lead quality or downstream sales problems. Account for conversion lag and small samples before recommending cuts. Prioritize reversible actions and explain the risk of each recommendation. Do not infer incremental return from platform-reported attribution alone. OUTPUT FORMAT Provide a data-quality assessment, a waste-and-opportunity table, a prioritized seven-day action plan, and a list of analyses that require additional data. Show formulas for calculated metrics. QUALITY CHECK Avoid fabricated statistics, benchmarks, or missing values. Flag assumptions and label every finding as observed, calculated, or hypothesized.
