Lead churn refers to the rate at which leads disengage, lose interest, or exit the sales funnel before converting into customers. High lead churn can indicate ineffective nurturing, poor targeting, or slow follow-up times. Reducing churn involves improving engagement strategies, optimizing response times, and using automation to maintain consistent communication. Businesses monitor lead churn through CRM analytics, helping identify drop-off points and adjust marketing efforts accordingly. Lower churn rates lead to improved sales performance and a healthier pipeline.
