Amazon PPC Amazon PPC (pay-per-click) allows Amazon sellers to bid on keywords (and competing products) in order to display their product when a customer is browsing the platform. When a buyer clicks on an ad, the seller is charged a fee. The nature of PPC on Amazon makes it very targeted and one of the most cost-effective ways for Amazon sellers to advertise. In order to maximize your return on investment, it is highly advised to work hard at developing good products with clear USPs (unique selling propositions) and optimize Amazon listings to achieve the best conversion rate possible. Sellers can also utilize a wide range of Amazon PPC tools to help optimize campaigns and reduce the time spent managing them.
