How Are Negative Keyword Decisions Made?
← Back to How to Find Profitable Competitor ASIN Targets in Amazon Ads
Quick answer
Negative keyword decisions in Amazon Ads are made by reviewing search term performance against actual campaign data such as spend, clicks, sales, and conversion rate. Instead of using one universal threshold, the process identifies terms that receive exposure but do not convert efficiently. Based on that performance, the tool suggests either adding a negative keyword to block a term or lowering the bid to reduce how often it appears. This approach prioritizes observed results over assumptions.
In practice, that means the system is not guessing. It uses performance already recorded in your campaign reports. For example, the Amazon Negative Keyword Tool by Todoza groups underperforming search terms into negative keyword candidates or bid-reduction opportunities, which you can then review before applying changes.
Which Metrics Matter
A useful negative keyword decision usually combines several data points rather than looking at spend alone. Search terms that earn clicks but fail to produce sales are obvious candidates, while terms with some sales but a weak conversion rate may be better handled with a bid adjustment.
- Spend and clicks: identifies terms consuming budget without meaningful engagement.
- Sales and conversion rate: separates total waste from terms that still contribute.
- Performance over time: helps avoid reacting to one day of noise.
When these signals are evaluated together, the recommendation is more grounded in actual campaign behavior.
Choosing Between Negation and a Lower Bid
Not every inefficient search term should be blocked outright. The cleaner approach is to match the action to the problem.
- Add a negative keyword when a term has repeated spend without conversions and shows little chance of improving.
- Reduce the bid when a term still converts occasionally but falls below the target return on ad spend.
- Leave the term active if it is a new term with limited data and no clear trend yet.
The tool presents these as recommendations, not automatic changes, so an advertiser can use judgment before making updates.
When This Matters Most
This methodical review becomes more valuable when campaigns grow across multiple ad groups, accounts, or marketplaces. Low-performing terms can hide in large search term reports, gradually consuming budget. A structured cleanup workflow makes those terms visible and organizes the next actions.
It also supports a read-only review process: the dashboard does not edit live campaigns automatically. Bid changes, negative keywords, and pauses are applied only after a person approves them. That keeps optimization decisions deliberate and reversible.

Cleaning up low-converting search terms is a practical step in the same optimization loop used to find profitable competitor ASIN targets. Once wasted spend is reduced, more budget can shift toward placements and targeting options that actually produce orders. This fits directly into the broader process of finding profitable competitor ASIN targets.
