how to start an amazon seller business involves selecting a niche, sourcing products, creating a seller account, and building optimized listings. The process begins with research—analyzing what’s trending, profitable, and sustainable over time. Once a product is chosen, sellers secure inventory, typically from Alibaba or domestic suppliers. After creating an Amazon Seller Central account, listings are created with SEO in mind. Fulfillment can be handled via FBA for automation or FBM for control. Continuous optimization, customer feedback, and marketing strategies help drive growth and ensure long-term success on the platform.
