In the customer lifecycle funnel, "keep customers" refers to the strategies and actions a business employs to retain existing customers and maintain their loyalty over time. This phase focuses on ensuring customer satisfaction, building strong relationships, and delivering consistent value to prevent churn. Techniques used in this stage include providing excellent customer service, offering personalized experiences, implementing loyalty programs, and maintaining regular communication through newsletters or updates. By effectively keeping customers engaged and satisfied, businesses can reduce acquisition costs associated with attracting new customers and benefit from repeat purchases and positive word-of-mouth referrals.
