What does AIDA stand for and why is this model still relevant in modern marketing?

AIDA is an acronym that stands for Attention, Interest, Desire, and Action, representing the four stages consumers typically go through when making a purchase decision. This model, first proposed by Elijah Elmo Lewis in 1898, remains relevant because of its adaptability to changing market conditions and its universality across both traditional and digital marketing channels. Despite the development of new marketing methods and techniques, the basic assumptions of the AIDA model prove its enduring effectiveness in guiding customers through the purchasing process.
