When to Use Campaign vs Ad Group Negatives
← Back to Campaign-Level vs Ad Group-Level Negative Keywords on Amazon: Where Should You Add Them?
Quick answer
Campaign-level vs ad group-level negative keywords on Amazon refer to how broadly you want to block certain search terms from triggering your ads. Campaign-level negatives prevent an unwanted keyword from triggering any ad within your entire campaign. Ad group-level negatives let you fine-tune which specific ads or product sets should be excluded from showing for a keyword, offering more precise control over ad targeting.
Choosing between campaign-level and ad group-level negative keywords can shape your ads’ reach and effectiveness on Amazon. Understanding the implications of each approach helps you maximize valuable ad impressions while controlling spend.
Strategic Use of Campaign-Level Negatives
Campaign-level negative keywords are best for search terms you consistently don’t want triggering any ad in your campaign. For example, if a term is irrelevant to every offer in a campaign—like unrelated brands, out-of-scope product types, or competitor products—add it as a campaign negative to save budget and simplify management. This removes unnecessary overlap or redundant exclusions across ad groups and keeps your campaign focused.
When to Use Ad Group-Level Negatives
Ad group-level negatives are useful when you want to block a search term from certain ads but not others. This is essential when ad groups target different product variations, or when the same keyword is helpful for some products and problematic for others. Ad group negatives give you granular control, letting some ad groups remain eligible for certain searches while others are filtered out.
Practical Workflow and Decision Support
Reviewing search term performance helps determine the right negative level. Tools like the Amazon Negative Keyword Tool by Todoza can classify search terms based on campaign data, highlighting when a negative should be applied campaign-wide versus at an ad group. Use performance signals such as spend, clicks, and conversions to guide your exclusion choices and avoid blocking valuable traffic.
