For a product to appear in the search results on Amazon, its listing must contain all the major keywords used by the customer to find the product. It is one of the many factors through which Amazon’s A9 algorithms rank a product in the search results. If your listing is optimized with all the necessary keywords, then Amazon will display your product for all those queries.
Hence, the main objective of keyword research for Amazon is to gather all such keywords and search queries, relevant to the product. It involves going through every source possible to build an exhaustive list. You don’t want to miss out on any potential sale and for that to happen, your products need to be visible clearly on Amazon. In order words, collecting keywords will help more customers see your products and ultimately, lead to more sales.
