Salecalc is a free website that calculates your potential net profit, return, and margin based on granular item details. Once you've discovered successful products to sell, you can use several tools to determine a potential item's profitability. Amazon reviews are another helpful resource for gauging consumer interest and identifying gaps in the market. You can use keyword research to measure consumer demand for the product and the level of competition surrounding it. To gauge an item's chance of success and profit, consider qualities such as ship weight, sturdiness, category popularity, competition, wholesale price, and shipping costs. As you dive in, look for generic items that don't rely on the appeal of a brand name and those that would be easy to ship. You can browse by category to hone in on items in a specific niche or explore rising trends and new releases. The Amazon Best Sellers list is an excellent place to start your research and find promising item ideas. For your Amazon products to be successful, they must be profitable, in demand, and not dominated by well-established brands. Part of carving out your selling strategy is performing product research to identify the best items to sell.
