## How These Metrics Relate

* **ROAS** = Revenue ÷ Spend — measures overall profitability
* **CPA** = Spend ÷ Purchases — measures acquisition cost
* **New Customer metrics** filter to first-time buyers only

A ROAS above 1x means revenue exceeds spend. Target CPA depends on your margins and customer lifetime value.

## Choosing the Right Metric

* **Profitability focus**: Use ROAS to ensure revenue exceeds spend
* **Acquisition campaigns**: Use CPA/CPP to measure cost per outcome
* **New customer acquisition**: Use New Customer metrics to isolate first-time buyer efficiency
* **Budget allocation**: Compare ROAS across campaigns to optimize spend distribution
* **LTV analysis**: Compare CPA against customer lifetime value for sustainable growth
