what is the best way to sell online often depends on individual goals, but Amazon FBA remains one of the most efficient methods due to its reach and infrastructure. Selling online successfully involves selecting the right platform, sourcing high-quality products, understanding your target audience, and optimizing listings for conversion. For beginners, marketplaces like Amazon, eBay, or Etsy offer a low barrier to entry. For those seeking more control, building a Shopify store may be better. Regardless of the platform, success requires good branding, customer service, and inventory management.
