Aeller seems to be a typo of “seller.” In the context of Amazon, a seller is anyone who lists and sells products on Amazon’s marketplace. Whether you’re an individual looking to sell personal items or a large company selling products globally, being an Amazon seller allows you to tap into one of the world’s largest online marketplaces. The key to success as a seller lies in optimizing your product listings, managing inventory, and using tools like Amazon FBA to streamline order fulfillment and customer service.
