CPA

Remember how conversion rate was an indicator of the success of a campaign? Well, Cost per Acquisition also measures the impact of a campaign, but it’s a financial metric. It calculates the cost a business incurs to acquire a new customer or subscriber to take an action. In other words, it’s the waiter that brings you the bill for those conversion meals. 

Calculating CPA involves considering factors like advertising expenses, sales team costs, and lead generation efforts, the total expenses, divided by the number of conversions during a specific period. 

Cost per acquisition is crucial in ecommerce as it helps companies evaluate the effectiveness of their marketing campaigns and allocate resources efficiently. This knowledge allows companies to optimize their marketing efforts and focus on targeted strategies.

But CPA alone is not enough. Hardly any metric is. CPA must be compared against customer lifetime value (CLV) to gauge profitability. As long as CPA remains lower than CLV, things are fine. A positive ROI and the promise of a potentially prosperous campaign await. However, if the CPA exceeds the CLV, it’s time to go back to the drawing board and reevaluate strategies.
