Final answer:
Return on Investment (ROI) and Customer Lifetime Value (CLV) are two marketing profitability metrics that provide insights into the relative marketing efficiencies of different net marketing contributions.
Step-by-step explanation:
The two marketing profitability metrics that allow a business insight into the relative marketing efficiencies of various net marketing contributions are Return on Investment (ROI) and Customer Lifetime Value (CLV).
ROI measures the profitability of a marketing campaign by comparing the net profit generated to the cost of the campaign. It helps businesses assess the overall efficiency and effectiveness of their marketing efforts.
CLV quantifies the value of the relationship between a customer and a business over their entire lifetime. It helps businesses identify and prioritize high-value customers and allocate resources accordingly.
