What Metrics Should I Track for Portfolio-Level Amazon Ads Reviews?

Core metrics to review

At portfolio level, the numbers to watch fall into two groups: spend efficiency and customer response. Start with total ad spend and wasted spend to understand how much budget is going toward terms or targets that do not convert. Then look at return on ad spend, conversions, traffic, and cost per sale to see whether that spend is producing profitable demand.

Amazon Ads Dashboard by Todoza can help pull those metrics into one view across accounts and marketplaces.

• Ad spend and wasted spend — total investment and the portion not generating meaningful returns.
• ROAS — revenue generated for each dollar of ad spend.
• Traffic and conversions — how many shoppers clicked and how many completed a purchase.
• Cost per sale — average advertising cost required to acquire one sale.

How to read the metrics across accounts

Do not evaluate any metric in isolation. A high ROAS account might still have growing wasted spend if broad keywords are draining budget. Compare accounts side by side and look for trends over time. For example, if traffic is rising but conversion rate is falling, the issue may be a mismatch between search terms and the product detail page rather than a budget problem.

Use automated reporting to keep the review consistent. Scheduled imports and performance snapshots reduce the manual work of pulling the same numbers each week, especially when multiple Amazon accounts or marketplaces are involved.

When this matters

This metric set is most valuable when you manage several Amazon accounts, marketplaces, or product lines. Without a shared portfolio-level view, a profitable account can mask waste in another. Reviewing spend, ROAS, and cost per sale together makes it easier to spot anomalies and assign cleanup tasks before small inefficiencies become large budget leaks.
