Running Amazon PPC campaigns can be a powerful way to boost sales—but without careful optimization, it’s also an easy way to waste your budget. Many sellers unknowingly bleed money by targeting the wrong keywords, neglecting campaign structure, or ignoring critical data. If your ACoS (Advertising Cost of Sale) is creeping higher or your profits are dipping, it might be time to audit your strategy.
Here are five common ways you might be wasting money on Amazon PPC—and how to fix them:
1. Bidding on Broad Match Keywords Without Control
Broad match keywords can help you discover new search terms, but they often trigger irrelevant queries. If not monitored, you could end up paying for clicks that never convert.
Example: Bidding on “coffee mug” might show your ad for searches like “travel coffee thermos,” which may not match your product at all.
Fix it:
-
Use negative keywords to filter out unrelated searches.
-
Regularly analyze your Search Term Report to find and eliminate wasteful terms.
-
Test phrase and exact match types for better control.
2. Ignoring Negative Keywords
Many sellers forget to add negative keywords, which means Amazon keeps showing their ads for searches that don’t lead to conversions. This leads to unnecessary impressions and wasted spend.
Fix it:
-
Add negative keywords to your campaigns weekly.
-
Start with obvious mismatches (e.g., “free,” “DIY,” or unrelated brand names).
-
Monitor poor-performing terms and block them.
3. Overlapping Campaigns Cannibalizing Each Other
Running multiple campaigns with overlapping keywords can create internal competition—driving up CPCs and reducing efficiency.
