Pinpoint Underperforming Keywords Before They Drain Your Budget
← Back to Why Is My Amazon Ads Spend Rising Faster Than Sales?
Quick answer
Underperforming Amazon Ads keywords are search terms that spend budget without delivering enough conversions or revenue to meet the account's efficiency targets. They often sit inside broad, auto, or long-tail matches and can go unnoticed while aggregate spend trends look acceptable. Pinpointing them before they drain the budget means reviewing search term reports against cost, clicks, orders, and ROAS, then separating terms into negatives, bids to reduce, or opportunities to test. That process keeps budget moving toward the terms actually supporting sales.
The harder part is doing this consistently without getting lost in large search term reports. A focused cleanup process can turn raw data into a clear list of terms to negate, lower, or keep, so budget decisions are based on signals rather than guesswork.
Where Budget-Draining Keywords Tend to Hide
Underperforming terms rarely appear as one obvious target. They often show up as high-impression, low-click queries, or as clicks with no orders after a meaningful window. Broad and auto match campaigns are common hiding places because Amazon can match a phrase to many close variants that each burn a little budget.
- Broad and auto match terms with high impressions but low click-through
- Search terms with multiple clicks and no sales after the expected conversion window
- Long-tail variants that duplicate a higher-performing exact match term
Reviewing those terms against campaign-level goals helps separate harmless exploration from consistent waste. A term with repeated clicks, no orders, and spend above the account's typical cost per acquisition is a stronger negative keyword candidate than a term with one click and no history.
Prioritize Cleanup with a Ranked List
Manual scrolling through search term reports makes it easy to miss terms that bleed small amounts across multiple campaigns. A better approach is to build a cleanup queue that ranks terms by signals such as spend, clicks, orders, and ROAS. The Amazon Negative Keyword Tool by Todoza is designed to organize search terms into that kind of prioritized list using campaign-specific metrics.
Reports can be imported via CSV or XLSX, or scheduled as daily email reports, which helps keep the cleanup queue current as new search terms appear. From there, the team can decide which terms to negate, which bids to lower, and which to leave running. Because the tool is read-only, those decisions stay with the account owner rather than being applied automatically.
When This Matters Most
Early keyword cleanup is most valuable when total ad spend is climbing before a corresponding lift in sales, or when a campaign's blended ROAS slips even though top-line revenue looks stable. It is also worth doing before expanding budget, because additional spend often flows into the same low-performing pockets if left unchecked.
Teams managing multiple campaigns benefit the most, because a small leak in several places can add up quickly. A consistent review cadence helps catch those terms before they accumulate into a larger budget problem.

Pinpointing underperforming keywords is one step in a wider Amazon Ads cost review. Once low-value terms are removed or reduced, the next question is whether the remaining spend is still rising faster than sales because of competition, seasonality, or campaign structure.
