How Do I Know if My Negative Keywords Aren’t Working?
← Back to Why Your Amazon Negative Keywords Aren't Working and How to Fix Them
Quick answer
Signs that Amazon negative keywords aren’t working include continued ad spend on irrelevant or low-converting search terms, high wasted spend, and limited improvement in ad performance metrics. These issues can indicate negative keywords are too broad, too narrow, or incorrectly applied, leaving your campaigns exposed to unwanted traffic.
Noticing your Amazon ads still spending money on unrelated or poor-quality searches? This is a strong indicator that your negative keywords aren’t set up optimally. Let’s look at the most telling signs and what you can do about them.
Key Warning Signs
Some common symptoms show when negative keywords are failing to filter out unwanted queries:
- Your search term report shows ongoing spend on terms you’ve attempted to block.
- Increasing ad spend on non-converting or irrelevant keywords.
- Steady or rising wasted spend despite adding negatives.
If you catch these patterns, review your negative keyword lists and placements.
Common Causes for Ineffective Negatives
- Negatives are too generic: Broad exclusions often miss closely related wasteful queries.
- Negatives applied to the wrong campaigns: Make sure every campaign’s list is relevant to its targeting.
- Phrase and exact match confusions: Know the differences—phrase negatives stop only certain word orders, while exact type blocks specific entries.
How to Catch and Fix These Problems
Routine audits are essential. Regularly scan Search Terms reports for unwanted matches that have slipped through. A tool like the Amazon Negative Keyword Tool by Todoza helps flag underperforming search terms and highlights candidates for new negatives, giving teams visibility across products and campaigns.
When This Matters
These warning signs are especially important if you manage large campaigns or multiple brands, where wasted spend can add up fast and negatives are harder to track manually.
