← Back to How to Compare Amazon Auto Targeting Groups by ROAS
Quick answer
Amazon auto targeting group ROAS differences are visible when you place each group's spend, sales, and conversions in a single comparison view. Scorecards that normalize the data by targeting expression let you see which groups clear your efficiency threshold and which are consuming budget without enough return. This turns raw Amazon Ads reports into a practical read, so you are not estimating performance from a blended account-level number.
Most Amazon Ads reports already contain the numbers you need, but the gaps between targeting groups only become obvious when they are arranged next to each other. A consistent comparison removes the manual work that often hides small ROAS differences.
Pull targeting-level ROAS into one view
Start with a report that includes the targeting group or targeting expression as a dimension. Group the rows by that dimension and calculate ROAS as sales divided by ad spend over the same date range. A dashboard tool like Amazon Ads Dashboard by Todoza can consolidate scheduled report imports so the comparison stays current.
- Use one consistent ROAS target across all groups
- Compare the same date window for each group
- Keep spend volume alongside ROAS to avoid misleading low-volume wins
Read the differences, not just the ranking
A simple ranking can overstate small differences. Watch for groups that look efficient only because they have very little spend, and groups that drive sales but fail to clear your threshold at higher volume. If your data includes search terms within those groups, you can also see whether a small number of queries is pulling ROAS down.
- Compare ROAS with weekly spend volume
- Segment by campaign or marketplace if the account is mixed
- Review underperforming search terms inside each group
When this matters
This matters when auto campaigns run across several products, accounts, or marketplaces. A small ROAS gap may not be obvious in a blended report, but at higher ad spend it can add up. A read-only scorecard or dashboard view is useful here because it keeps the analysis focused on identifying differences before you decide where to move budget.
