Which type of layout encourages unplanned purchasing among customers?

The loop layout is effective in encouraging unplanned purchasing because it creates a continuous path for customers to follow throughout the store. This layout typically guides customers in a circular or figure-eight pattern, exposing them to various product categories and displays as they move through the space. The design encourages exploration and can result in impulse buys, as customers may discover items they were not initially seeking. The layout draws attention to different areas and products, increasing the likelihood of adding unplanned items to their shopping carts.

In contrast, other layout types, such as the grid layout, are designed for efficiency and ease of navigation, leading to a more straightforward shopping experience that may limit spontaneous purchases. The department layout organizes products in distinct sections, which can also lead customers to stick to their shopping list rather than encouraging broader exploration. The free-form layout can promote a more relaxed shopping atmosphere but may not consistently drive traffic through the entire store like the loop layout does. Thus, the loop layout stands out as the most effective for promoting unplanned purchasing behaviors.
