Sales ranking refers to the position of a product or service based on its sales performance compared to others in the same category. This ranking is often determined by the number of units sold, revenue generated, or market share. Companies use sales rankings to assess their performance and identify trends in consumer preferences. Retailers and online platforms, such as Amazon or Walmart, frequently display sales rankings to help customers make informed purchasing decisions. Higher-ranked items are typically seen as more popular or desirable, influencing consumer behavior and potentially driving further sales for those products.
