The Grocery grid layout varies as much as the storefronts themselves. Some retailers will pack products densely onto a store floor, whereas others will space them out for casual browsing. Many businesses use signage to help customers navigate their surroundings, while others allow their products to speak for themselves. Grocery grid layout can even be combined in novel ways. All retail stores have in common, regardless of size or industry category, are their entrances. The store's exterior can draw customers' attention and encourage passers-by to enter through display windows or outdoor signage. Exteriors can also be used to promote special promotions, products, or line-ups that will appeal to your target audience.
