what are good items to sell on amazon depends on current trends, seasonality, and competition levels. Generally, small, lightweight, and high-demand items with low competition are ideal. Categories like home improvement, kitchen gadgets, fitness accessories, and pet supplies often perform well. Products that solve specific problems or cater to niche audiences can also generate strong ROI. Tools like Helium 10 or Jungle Scout help identify these winning products. The key is balancing profit margin, customer demand, and your ability to differentiate through branding or bundling.
