How to Pinpoint Inefficient Amazon Search Terms
← Back to Amazon Search Term Impression Share: When Should You Increase Bids?
Quick answer
Inefficient search terms are Amazon Ads queries that generate regular impressions or clicks but fail to meet the campaign's ROAS or conversion expectations. Identifying them involves grouping search-term performance data by spend, sales, clicks, and conversion rate, then flagging terms with high spend and low return. The goal is not always immediate negation; some terms may need bid reductions, more data, or placement review before action.
For Amazon advertisers, pinpointing wasteful search terms is the practical first step before deciding whether to raise bids on terms that are working. Without this cleanup, bigger bids can accelerate spending on the wrong queries.
What counts as an inefficient search term?
An inefficient search term usually shows one or more of these patterns: meaningful spend with no sales, a click-through rate far below the account average, or a cost-per-acquisition that exceeds the product's target. Terms that receive many impressions but no clicks can also drag down relevance if they accumulate over time.
- High spend, zero orders: the most direct signal for negation or bid reduction.
- Low CTR with high impressions: may indicate a relevance mismatch.
- High ACoS or low ROAS: may still be profitable at a lower bid, so test before negating.
Pinpointing inefficient terms without guesswork
Start by exporting a Sponsored Products search-term report for a meaningful date range, such as the last 14 to 30 days. Sort terms by spend in descending order, then compare orders and sales. Terms with repeated spend and no conversions are usually the clearest candidates for negative exact or phrase match.
Tools built for this work can speed up the review by classifying terms into groups such as "review before increasing," "reduce bid," or "negate." A tool like Amazon Negative Keyword Tool by Todoza can support that classification, but the output should still be reviewed by a person before any campaign changes are made.
When this matters
This matters most before you increase bids on high-performing terms. If you raise bids without identifying waste, you may spend more on the same inefficient queries, reducing the return from your better terms.
