The funnel metaphor represents the process of gradually narrowing down a larger group of potential customers (top of the funnel) into a smaller group of paying customers (bottom of the funnel).

The specific stages and strategies within a sales funnel may vary depending on the industry, product, and target audience. A well-designed and managed sales funnel can help businesses efficiently move potential customers through the buyer's journey, from initial awareness to conversion and beyond, while providing tailored content and support at each stage.
