Metrics & Measurement
What is CPA?
CPA stands for Cost Per Acquisition (or Cost Per Conversion).
It's calculated by dividing total advertising spend by the number of conversions generated.
For example:
Spend: $5,000
Conversions: 100
CPA = $50
CPA is one of the most important metrics because it connects advertising spend directly to business outcomes.
