Amazon PPC Guide
Stop paying for irrelevant clicks. Find, add, and maintain negative keywords that protect your ACOS.
Sellers who add negatives from their search term report in the first week typically cut wasted spend 15–30% before touching bids. See the full ACOS reduction guide.
Add negatives at the campaign or ad group level in Sponsored Products. Campaign-level negatives apply everywhere; ad group negatives are more surgical when you run multiple targets in one campaign.
Pull 30–60 days of search terms. Export to a spreadsheet. Filter: spend > $5 AND orders = 0. Add each term as a negative exact. For recurring junk patterns (competitor brands, wrong size, "free"), use negative phrase.
Wrong audience: "kids", "men", "professional". Wrong intent: "free", "diy", "how to make". Wrong product type: "replacement part" when you sell the whole unit. Wrong brand: competitor names you do not carry.
Review new search terms weekly. Amazon constantly matches new queries to your broad and auto campaigns. A standing negative keyword process is what separates profitable accounts from bleeding ones.
