A sales funnel is the process your prospects must go through before deciding to become your customers. Imagine a real-life funnel. At the top, some substance is poured in, which goes down to one fixed destination. In sales, something similar occurs. At the top, many visitors arrive who may enter your sales funnel. In contrast to a real sales funnel, not all visitors entering your sales funnel will emerge from the other end. However, by keeping in mind these key elements and not falling into the common pitfalls, you can improve the closing rate.
