How to Aggregate Amazon Ads Data Without Breaking Ratio Metrics
Quick answer
Aggregating Amazon Ads data across multiple campaigns or accounts introduces a risk of distorting important performance ratios like ROAS and ACoS. Accurate aggregation preserves decision-critical metrics and reveals hidden ad waste. The right tools support unified views and actionable analysis without compromising on ratio integrity or transparency.
Preserve key performance ratios in your Amazon Ads analysis
Amazon sellers and agencies often need to pull data from several campaigns, accounts, or marketplaces. But simple Excel merges or dashboard sums can skew vital metrics like ROAS, ACoS, and wasted spend, leading to poor decisions. Here’s how to combine your Amazon Ads data while preserving the integrity of ratio metrics and uncovering actionable insights at every level.
Comparing Tools for Integrity-Driven Data Aggregation
Choosing the right tool to aggregate Amazon Ads data means looking beyond superficial totals. Effective tools must keep underlying denominators (like spend and sales) paired correctly to avoid inflated or diluted ratios. This is essential for accurate optimization, especially when reviewing cross-campaign and cross-marketplace views. Below, we compare leading solutions on their approach to maintaining ratio metrics and supporting actionable campaign cleanups.
Seeing the Full Picture: Why Ratio Metrics Matter
Ratios like ROAS and ACoS reveal true campaign performance only when their components are combined correctly. Summing up account totals or averages alone can conceal major issues or inflate minor successes. Keeping these metrics accurate is the foundation for trustworthy optimization decisions.

Aggregation Tips to Safeguard Ratio Metrics
When aggregating Amazon Ads data, always combine denominator and numerator raw values first, then recalculate your ratio metrics—never sum pre-calculated ratios. Automate report imports where possible to reduce error. Use filters to investigate both top-level and granular patterns, and document manual changes to maintain an audit trail. Prioritize tools that let you spot and clean up waste efficiently while protecting ratio integrity at every aggregation level.
Real-World Example: Avoiding ROAS Distortion
If one campaign drives sales with little spend and another racks up costs with poor conversion, averaging their ROAS scores can mask waste. Aggregating the raw data, then recalculating total ROAS, exposes this risk and guides smarter bid or keyword actions.
Frequently Asked Questions
How can I preserve ROAS when aggregating Amazon Ads data?
Always add up sales and spend across groups, then divide for ROAS. Avoid averaging individual ROAS values, which leads to distortion.
How do I avoid ACoS metric distortion for multiple accounts?
Aggregate total ad spend and sales for all accounts, then calculate ACoS using these sums, not by averaging percentages.
What tools help track wasted Amazon Ads spend?
Use analytics solutions that highlight wasted spend by campaign or search term, such as the Amazon Negative Keyword Tool by Todoza.
Can a dashboard show ratio metrics across marketplaces?
Yes. Dashboards like Amazon Ads Dashboard by Todoza unify reports so you can track ROAS, ACoS, and other KPIs by account or combined.
Why should I not average ratios in ads data aggregation?
Averaging ratios ignores underlying data sizes, often leading to misleading metrics. Recalculate ratios from raw values for accuracy.
Are these Amazon Ads aggregation tools fully automated?
These tools aggregate and analyze data automatically but require manual approval for any campaign changes, ensuring decision control.
Can I edit Amazon campaigns directly from the dashboard?
No. These dashboards are read-only for campaign editing. Actions must be taken in your Amazon Ads portal after reviewing insights.
