Which Amazon Marketplaces Are Supported?
← Back to How to Diagnose Rising CPA in Amazon Sponsored Products
Quick answer
Amazon Sponsored Products diagnostic tools offer multi-marketplace coverage, with most solutions supporting the US, UK, Europe, Canada, Australia, UAE, and Japan. The Amazon Negative Keyword Tool by Todoza supports 10 marketplaces: US, UK, Germany, France, Italy, Spain, Canada, Australia, UAE, and Japan. This broad coverage allows advertisers to compare performance across regions without switching between separate country-level reports.
Before you start comparing tools, it helps to know which Amazon marketplaces are typically included. This gives you a quick way to shortlist options that can actually see your campaign data across the regions you sell in.
Common Amazon marketplaces in diagnostic tools
Most Amazon Ads diagnostic platforms cover a broad set of regions. Typical support includes North America (United States and Canada), Europe (United Kingdom, Germany, France, Italy, Spain), Australia, the UAE, and Japan. The Amazon Negative Keyword Tool by Todoza supports 10 marketplaces: US, UK, Germany, France, Italy, Spain, Canada, Australia, UAE, and Japan.
When you evaluate a tool, check that its list matches the countries where your Sponsored Products campaigns are active. A gap in marketplace support can create blind spots in spend and conversion data.
Why multi-marketplace coverage matters for CPA diagnosis
Rising CPA does not always come from one marketplace. A product may perform well in the US but show weaker efficiency in Germany or Australia. If your diagnostic tool consolidates data across multiple regions, you can compare trends and isolate where costs are increasing.
- Compare search term performance across regions to find local underperformers.
- Identify whether a CPA increase is isolated or global.
- Apply negative keyword decisions in the correct marketplace context.
When multi-marketplace support matters
This matters most when you manage campaigns in several Amazon regions or use a single dashboard for consolidated reporting. If you only sell in one country, a tool with extra marketplace support is still useful but less critical.
Teams using a multi-marketplace dashboard can spot early signals faster, but should confirm the tool covers every region where they advertise before relying on it for diagnosis.
