Should You Analyze Amazon Ads Spend Across All Marketplaces?

Why Marketplace-Level Review Catches Waste

Amazon Ads reports often look acceptable when totals are averaged across marketplaces, but that blended number can hide poor performance in one or two regions. A marketplace that generates lower clicks or conversions may still spend steadily, especially if budgets are set globally and not reviewed locally. Checking each active marketplace separately makes it easier to spot spend that does not support a clear return.

• Small regions can still produce meaningful waste when they are left running without local monitoring.
• CTR and conversion expectations vary by marketplace, so one blanket ROAS target may not fit every country.
• Negative keyword needs differ by language and shopping culture, making local review more useful.

For teams managing multiple marketplaces, the Amazon Negative Keyword Tool by Todoza can help because it supports 10 Amazon marketplaces and multiple account workflows.

How to Structure a Practical Multi-Marketplace Check

Start by pulling reports for every marketplace where you have active campaigns, even if the spend looks small. Convert local currency spend to your reporting currency for comparison, then review each marketplace against its own target ROAS and cost-per-order trend. A unified dashboard can reduce the manual work of combining reports from different regions.

• List all active marketplaces and map them to account-level budgets.
• Compare current period spend and sales against the previous period for each marketplace.
• Flag marketplaces where spend is rising while orders or conversion rate are falling.
• Prioritize the largest absolute waste first, but still capture smaller regional issues before they grow.

A tool like the Amazon Ads Dashboard by Todoza provides a centralized view of spend, sales, ROAS, and wasted spend so you can drill down from account to campaign and search term.

When This Matters

A marketplace-level review is especially useful when you expand into a new Amazon region, manage multiple client accounts, or run campaigns in countries with different languages and buying patterns. It also matters when a marketplace has low overall spend but high cost per conversion, because that pattern can continue for weeks before it becomes obvious in a combined report.
