A sales funnel is a way of describing the steps a customer goes through when they are considering buying a product or service. The goal is to turn them into a paying customer. The funnel typically starts with attracting a potential customer’s attention, then getting them interested in the product, building desire for it, and finally getting them to take action and buy it. Marketing tactics are used to move the customer through the stages of the funnel, with the ultimate goal being to make a sale.
