Amazon Pay-Per-Click (PPC) is a form of advertising offered by Amazon that allows sellers to bid on keywords and pay for their products to be displayed in sponsored search results on the Amazon website. This is similar to Google AdWords, where advertisers bid on keywords and pay for their ads to appear at the top of search results. Amazon PPC includes Sponsored Product Ads, Sponsored Brands Ads, and Sponsored Display Ads.
By using Amazon PPC, sellers can increase visibility and sales of their products on the Amazon platform. However, it's important to note that PPC can be competitive and requires monitoring and optimization in order to be effective.
