Consolidate Amazon Ads Performance Data Across Campaigns

What a clean consolidated dataset includes

A useful consolidation should include the same core fields from every active campaign: date, account, marketplace, campaign name, ad group, search term, spend, sales, orders, clicks, and impressions. Keeping these fields aligned is more important than having every possible metric.

If your reports come from different Amazon marketplaces or accounts, add an identifier column for each source. That simple step makes it possible to filter performance without losing the original context.

Set up a comparison-ready view

After standardizing the fields, add a date column and a day-of-week column. This lets you isolate weekends and weekdays without rebuilding the dataset later. For most advertisers, grouping data by day name while retaining campaign and search term detail gives the clearest picture.

• Keep one row per search term and date where possible
• Preserve target ACOS or ROAS fields for quicker filtering
• Tag missing or partial data so it does not skew comparisons

Reduce manual consolidation with reporting tools

Manual merges work for small accounts, but they become fragile as campaigns multiply. A reporting tool can accept multiple file formats and source accounts, then normalize the data into a single dashboard or export.

The Amazon Ads Dashboard by Todoza is designed for this type of consolidation and provides drill-down from account level to individual search terms. For identifying wasted spend once data is combined, the Amz Ad Waste Detector can track ROAS below target across accounts.
