Quick answer

Amazon campaign performance improves when negative keywords are added promptly to block search terms with high spend but low or zero conversions. This action helps reduce wasted advertising budget, refine ad targeting, and ensure ad spend is directed toward searches most likely to generate sales. Regularly updating your negative keyword list is a practical step in effective campaign optimization.

Optimizing Amazon ad campaigns means paying close attention to how your ads spend money. Spotting underperforming search terms early makes it easier to refine your strategy and prevent unnecessary spend.

Identifying Negative Keyword Opportunities

Check your search term reports regularly for terms that consistently spend your budget but generate little or no conversions. High-spending, non-converting terms indicate a mismatch between shopper intent and your product. By flagging these terms as negative keywords, you prevent your ads from appearing for searches unlikely to result in sales, thereby protecting your advertising investment.

How to Add and Manage Negative Keywords

Add negative keywords as soon as inefficient search terms are identified. This can be done directly within your Amazon Ads interface or by using a specialized tool. For example, the Amazon Negative Keyword Tool by Todoza helps import search terms and evaluates them by campaign metrics to streamline the cleanup process. Revisit your negative keyword list regularly to ensure it remains aligned with your evolving campaign goals.

When This Matters Most

  • Managing multiple campaigns or large budgets where wasted spend can quickly add up.
  • Launching new ads that may target broad or generic search queries.
  • Trying to maintain a healthy ACoS and maximize your return on ad spend.
