Which metric is used to measure marketing performance by examining the total revenue attributed to a customer?

The metric that measures marketing performance by examining the total revenue attributed to a customer is customer lifetime value (CLV). CLV represents the total worth of a customer to a business over the entirety of their relationship. This metric helps businesses understand how much revenue they can expect from a customer, which is essential for making informed decisions regarding marketing strategies, customer service, and resource allocation.

By calculating CLV, companies can evaluate the effectiveness of their marketing efforts, identify the most profitable customer segments, and tailor their strategies to enhance customer retention and satisfaction. Understanding CLV ultimately allows businesses to invest in initiatives that yield the highest returns because they have a clear picture of the long-term value a customer brings.

The other options related to specific metrics have different focuses. Cost per acquisition measures the cost associated with acquiring a new customer, click-through rate tracks the effectiveness of online ads by measuring how often users click on them, and return on investment evaluates the profitability of an investment compared to its cost. While all these metrics are valuable in their own right, they do not specifically assess the total revenue contribution of a customer like customer lifetime value does.
