How do I detect wasted ad spend across currencies?

Start with a consistent multi-marketplace view

Begin by bringing campaign data from each Amazon marketplace into one read-only view. The Amazon Ads Dashboard by Todoza tracks spend, sales, ROAS, ACoS, orders, clicks, CPC, CTR, conversion rate, and wasted spend across accounts. This helps you compare trends without editing live campaigns from the dashboard.

Use that baseline to spot accounts or marketplaces where spend continues without a proportional return. Once you see the pattern, move to the search terms driving it.

Evaluate search terms, not just totals

Waste often hides inside broad or loosely matched search terms that appear acceptable at campaign level. The Amazon Negative Keyword Tool by Todoza imports search term reports and classifies terms as negative keyword candidates, bid-reduction opportunities, or items that need more data. It evaluates each term against campaign-specific signals rather than forcing one universal threshold.

• Import Search Terms reports via CSV/XLSX or scheduled email
• Separate negative keyword candidates from bid adjustments and low-data terms
• Keep live campaign changes manual and approval-based

When this matters

This approach matters most when daily FX and monthly FX reporting produce different performance signals. Currency conversion can make a keyword look stronger or weaker than it really is, especially across multiple marketplaces. Reviewing waste at the search-term level with daily data helps separate real performance changes from simple exchange-rate movement.

Amz Ad Waste Detector supports this by tracking daily recommended actions and search terms with lower-than-target ROAS, while keeping campaign changes read-only until you approve them.
