Merchandising involves actions taken to promote and display products at the point of sale to encourage consumers to purchase them. It aims to improve profitability, optimize product exposure, and control product flow. There are different types of merchandising including permanent displays for regular products, promotional for special offers, management of attractive space and category presentation, and seduction merchandising that meets consumers outside of stores. Elements to consider at the point of purchase include shelves, furniture, lighting, signage, product placement, sensory aspects, and personal attention. The layout, or floor plan, arranges products strategically by category, brand, price, and supplier agreements.
