A business funnel is a marketing and sales tool that is used to visualize the different stages that a potential customer goes through on their way to becoming a paying customer. The funnel typically starts with a large number of potential customers at the top, and as the potential customers move through the different stages of the funnel, the number of people decreases. The stages of the funnel may include activities such as learning about the product or service, considering the product or service, making a decision to purchase, and making the actual purchase. The business funnel is used to help businesses understand the customer journey and to identify where potential customers may be dropping out of the funnel, so that they can take steps to improve the customer experience and increase sales.
