A sales funnel is a systematic process that guides potential customers through the stages of awareness, interest, decision, and action. It’s designed to attract leads, nurture them with valuable content, and ultimately convert them into paying customers. You need a sales funnel because it provides a structured approach to marketing and sales, maximising your ROI by focusing your efforts on a defined process that moves prospects towards a purchase. Without a funnel, you risk losing leads and wasting valuable marketing spend.
