The smell of a bakery item in a supermarket significantly increases sales of baked goods from the bakery. Smell triggers a faster sense of time, such that in a scented location, the  time spent waiting in line appears shorter and the perceived quality of service higher. The more a product successfully triggers sensory stimulation in terms of type of sense and  strength of the sensory stimulus, the more attractive the product and the greater its market success rates.
Sensory branding research is engaged in fitting a brand with an ideal sensory mix and testing its effectiveness on the consumer, i.e. how a combination of sensory elements in a product's marketing mix (such as scent circulation at point of sale, music, lighting, package textures and more) influence the perception of a production and its potential.
