Promotional pressure is an indicator measuring the frequency with which promotions are used by a company or in a particular sector. There are various approaches to assessing this promotional pressure, such as the number of flyers distributed, the diversity of products involved, or the intensity of the discounts offered. This level of promotional pressure can fluctuate depending on various factors, such as the economic climate, existing competition, or changes in consumer habits. For example, in the retail sector, promotional pressure can increase during periods of crisis or when competition is more intense. Promotional pressure can be measured using various data sources. It is also common to use graphical representations to visualize the evolution of promotional pressure in the retail sector.
