One of the most effective strategies for lowering ACoS (Advertising Cost of Sale) in Amazon PPC campaigns is combining tight keyword targeting with constant search term pruning.
By focusing on high-converting, exact-match keywords and regularly reviewing the search term report, you can identify and add negative keywords to block irrelevant clicks that waste ad spend.
Alongside this, optimizing product listings for conversion (better images, pricing, reviews, and copy) ensures that the traffic you do pay for is more likely to convert.
Also, gradually shifting budget toward your top-performing campaigns while reducing bids on high-spend/low-return keywords helps you control costs and improve efficiency over time.
