A promotional model is a model hired to drive consumer demand for a product, service, brand, or concept by directly interacting with potential consumers. The vast majority of promotional models tend to be attractive in physical appearance. They serve to provide information about the product or service and make it appealing to consumers. While the length of interaction may be short, the promotional model delivers a live experience that reflects on the product or service he or she is representing. This form of marketing touches fewer consumers for the cost than traditional advertising media (such as print, radio, and television); however, the consumer's perception of a brand, product, service, or company is often more profoundly affected by a live person-to-person experience.
