ROAS Drop Root-Cause Analyzer

Build a SaaS tool that connects ad accounts, analytics, and store data to explain sudden return declines in plain English. It would detect whether the issue is likely traffic quality, attribution drift, checkout regression, device-specific failure, or inventory mix change, then prioritize next steps.

Pourquoi c'est important

You are running a profitable online store and one week your ad returns fall hard even though nothing obvious changed. The ad dashboard still shows traffic, your search terms look similar, and competition data does not reveal a clear answer. Now you are forced to compare multiple systems by hand to decide whether the problem is broken tracking, lower-quality traffic, or something wrong after the click. Existing tools give you numbers, not a diagnosis. What you need is a system that quickly tells you what most likely broke, how confident it is, and what to check first before you waste more budget or overreact with campaign edits.

Différenciation

Solutions existantes
Google AdsGA4Integrated tracking API
Notre angle
There is a gap for a lightweight diagnostic layer that translates cross-tool metrics into plain-language root-cause hypotheses and prioritized next actions for smaller advertisers.

Pourquoi cela pourrait échouer

Auto-contre-argument — le signal de confiance le plus important

  1. 1The diagnosis may feel too uncertain because automated ad products do not expose enough granular placement data to prove causality.
  2. 2Smaller merchants may prefer agencies or free spreadsheets if incidents are infrequent and they do not value continuous monitoring.
  3. 3Cross-platform setup friction could reduce activation if users struggle to connect analytics, ads, and store systems.

Résumé des preuves

Comment l'IA a synthétisé cet aperçu — pas de citations textuelles

Several participants focused on the difficulty of explaining a sharp decline when traffic and top-level reporting do not obviously signal the cause. Multiple comments recommended comparing store revenue, analytics data, and device-level performance, showing a need for cross-source diagnosis rather than another dashboard. There was also evidence that this kind of issue can persist for months, making a fast debugging layer commercially valuable.
