Campaign-Level vs Ad Group-Level Negative Keywords on Amazon: Where Should You Add Them?
Quick answer
Negative keywords are critical for controlling ad spend and improving targeting in Amazon Ads. The choice between campaign-level and ad group-level negatives affects how search terms are blocked and impacts reach and efficiency. Sellers need to consider campaign structure, targeting strategy, and waste minimisation when deciding at which level to implement negative keywords.
Master Amazon Ads control by choosing the right negative keyword level.
If you’re running Amazon Ads, you’ve likely heard about negative keywords — but should you add them at the campaign or ad group level? This guide walks you through the differences, best practices, and practical implications of each approach. Whether you’re an experienced PPC manager or an Amazon seller refining your strategy, understanding where to block wasted spend is crucial for smart optimization.
Overview: Comparing Campaign-Level and Ad Group-Level Negatives
Amazon Ads offers two ways to prevent irrelevant or poor-performing search terms: campaign-level and ad group-level negative keywords. Both strategies have unique strengths, and the right choice depends on your goals, account structure, and the nature of your ad groups.
- The broad impact of campaign-level negatives means a blocked term is excluded from all ad groups within that campaign. This is efficient for eliminating obvious waste across a wide set of products or targets.
- Choose a more surgical approach with ad group-level negatives to fine-tune which products or targeting types are excluded from specific search queries. This is valuable when you want to block a term for one ad group but let it run in others.
By understanding these differences, you can avoid over-blocking valuable terms or letting wasted spend slip through the cracks in complex Amazon accounts.
How Negative Keyword Placement Impacts Campaign Efficiency
Choosing campaign-level negatives simplifies account management by quickly excluding terms from all ad groups, but can unintentionally reduce reach if overused. Ad group-level negatives allow for precision, helping you tailor exclusions without affecting campaign-wide coverage. Teams often combine both for maximum control.

When selecting where to add a negative keyword, always ask: is this search term unwanted for all ad groups (campaign-level), or just specific ones (ad group-level)? For strong, consistent waste, use campaign-level negatives to cut across the board. For overlap or nuanced targeting, leverage ad group negatives. Reviewing search term performance data — ideally with tools that highlight risk and opportunity — helps you avoid suppressing valuable traffic while minimizing wasted budget.
Tips for Smarter Negative Keyword Management
Regularly review your search term reports and adjust negatives based on recent performance trends. Use tools that provide cross-campaign visibility so that negative keyword decisions are consistent and strategic, not reactionary. Collaboration and review before applying changes reduce risk.
