Questions
How do I calculate CPA?
Divide what you spent by the number of conversions. $500 for 20 sales is a $25.00 CPA.
What counts as an acquisition?
Whatever you are paying to get: a sale, a lead, a signup or an install. Pick one and measure it the same way every time.
What is a good CPA?
One that leaves profit. If a customer is worth $60 to you, a $25 CPA works and a $70 CPA does not.
