Review Which Search Terms Are Consuming Budget but Delivering Below-Average ROAS
← Back to How to Use Search Term Impression Share to Find Growth Opportunities
Quick answer
A below-average ROAS search-term review identifies the Amazon Ads queries that consume meaningful spend without generating proportional sales, so advertisers can shift budget toward profitable terms. This review typically ranks terms by spend and ROAS, flags negative-keyword candidates, bid-reduction opportunities, and terms needing more data before any campaign changes are made.
The manual approach works, but it is slow when you are looking at thousands of search terms across multiple campaigns. A clear ranking and action list helps you move from noticing wasted spend to actually reducing it before the next reporting cycle.
Prioritize by spend against your ROAS baseline
Start with search terms that have enough clicks or spend to be judged reliably. A term that has spent $40 and returned 0.8x ROAS is usually a clearer signal than a term with $4 and one conversion. Compare each term against your account or campaign average, not a fixed universal number.
Tools like Amazon Negative Keyword Tool by Todoza can rank terms by campaign-specific metrics like spend and ROAS, so the team starts with the most inefficient terms instead of reviewing alphabetically.
Separate waste from terms that need more data
Once you have a short list, place each term into one of three groups.
- Negative keyword candidates: high spend, clearly below ROAS, and not closely related to the product.
- Bid-reduction opportunities: some sales but not enough to justify current cost per click.
- More data needed: promising intent but too few clicks to decide.
This grouping prevents knee-jerk negatives on terms that might become profitable with a lower bid or more time.
When This Matters Most
This review matters most when total ACOS is creeping up, when a product receives many broad or auto-campaign clicks, or when impression share gains are not translating into profitable orders. A recurring review—weekly for active accounts or after a meaningful data window—keeps low-ROAS terms from compounding waste.
