Marketing Funnel of the AIDA Model is a marketing strategy that helps marketers to understand how the customer moves from awareness to consideration to decision. The process begins with an introduction in which the marketer makes their product or service known and creates awareness. The next step is when they decide on a target audience that would be relevant for their product or service. The third step is to send out information about their product or service so that people are more aware and interested in it. The final step is when people make a purchase and become customers.
