What is ACoS in Amazon PPC? | Forum

ACoS (Advertising Cost of Sales) is a key metric in Amazon PPC that measures the ratio of ad spend to sales revenue generated from the ads. It is calculated by dividing the total ad spend by the total sales and multiplying by 100. A lower ACoS indicates a more efficient campaign, meaning you're spending less to generate sales. Monitoring and optimizing ACoS helps in managing profitability and ensuring your PPC campaigns are cost-effective.
