Maria, la gerente de marketing de Jack and Jill, quiere optimizar sus campañas en función de las acciones de los clientes que compran por primera vez. ¿Cuál de las siguientes estadísticas deberían usar?

Maria should use "New-to-brand customers" because this metric directly measures the number of first-time buyers acquired through her campaigns. This aligns perfectly with her goal of optimizing for actions from customers who are purchasing for the first time. "Investment" (spend) is a total cost, not a measure of new customers. "Cost per click" (CPC) and "Click-through rate" (CTR) are engagement metrics that indicate how many people clicked on an ad and how efficiently those clicks were acquired, respectively. While CPC and CTR are important for campaign performance, they do not specifically tell Maria how many of those clicks resulted in a new customer, which is her primary objective.
