I’ve had this campaign running for months with great acos and I recently sent few products to fba. Sales are 2/3 a day some days more. I want to boost sales, how could I achieve this with ppc?

Before running PPC, Optimized your listings well. Then you run the auto and exact Campaign.Also run Pharase Campaign. Then targeting Products and Category Targeting as well. In the beginning your PPC ACOS will be more and, gradually it will decrease after few Months. Be Patience
