How to Monitor Underperforming Keywords Across Amazon Marketplaces

Why underperforming keywords hide across marketplaces

Amazon treats each marketplace as its own environment, so the same product may match different search terms in the US, UK, Germany, or Japan. A keyword that looks acceptable in one region can burn spend in another because of language differences, local competition, or buyer intent. Without a shared view, underperformers stay buried in separate reports.

Common signals that a keyword is underperforming include high clicks but no sales, spend well above target ROAS, and repeated impressions with weak conversion. Monitoring these signals across regions helps you compare marketplaces side by side rather than patching one account at a time.

Using one dashboard to prioritize negative keyword candidates

Cross-marketplace tools such as the Amazon Negative Keyword Tool by Todoza centralize keyword performance reports and highlight search terms that fail against campaign-specific thresholds like spend, clicks, and ROAS. Instead of checking each marketplace individually, you can review a single list of potential negatives and sort by the waste they create.

To keep the process manageable:

• Import Sponsored Products search term reports from each marketplace on a regular schedule.
• Filter by spend, clicks, and ROAS to separate urgent negatives from low-priority terms.
• Confirm the search term does not convert in one marketplace before blocking it in another.

When this matters

This matters most when you manage the same product or brand across several Amazon marketplaces and need to process a high volume of search term data. A single-marketplace seller can handle negative keyword review manually, but cross-marketplace coverage quickly becomes repetitive. A consolidated view reduces the time spent jumping between accounts and helps you spot regional patterns, such as a keyword that wastes spend only in Europe or only when local competition spikes.
