Eye tracking on shelves refers to the process of using specialized technology to monitor and analyze the eye movements of consumers as they browse and make purchasing decisions in a retail setting. This technique allows retailers and marketers to gain valuable insights into how shoppers interact with products on shelves, including which items catch their attention, how long they spend looking at each product, and which products ultimately lead to a purchase. By understanding the visual behavior of consumers, eye tracking on shelves can help businesses optimize product placement, packaging, and marketing strategies to increase sales and improve the overall shopping experience.
