Amz Ad Waste Detector takes a broader view, evaluating campaign waste, ROAS, and cleanup opportunities. Both are analytical tools that require team approval for changes and do not apply automatic campaign edits.
For sellers and agencies, the practical question is usually whether you need a focused Search Term workflow or a wider account health review. Many teams pair the two, using the Negative Keyword Tool to handle search term decisions and Amz Ad Waste Detector to see where spend is leaking across campaigns.
