We are the hero of our own story, and to build a successful business, one needs a lead - someone interested in your product or service who could be your next customer. A lead is not just anyone on the street; they're people who take action, show interest, and need your product to complete their story. The marketing funnel concept helps move potential customers from awareness to sale by starting with a wide group of people, then narrowing down to those who are highly likely to become customers. The journey from lead to customer involves capturing, nurturing, qualifying, and converting leads into sales. Customer retention and churn reduction strategies also play a crucial role in keeping existing customers around and encouraging them to make repeat purchases. By understanding the importance of leads and the marketing funnel, businesses can create effective sales strategies that help turn potential customers into loyal customers who complete their own story with your product or service.
