A hot-selling item on Amazon does not have to be a new product. Optimizing Amazon keywords is the most important step before you rank new products. You can try to select, classify and collect keywords through the Amazon search bar, similar product sales and high-ranking competitors, third-party keyword tools (such as Seller Home long-tail keyword discovery, Scientificseller, Amzdatastudio, MerchantWords keyword search tool) and other related channels, and apply them to product titles and descriptions. Do not use the same keyword repeatedly and ensure that the product title matches the keyword.
