Frequently asked questions
How is CPA calculated?
CPA = total ad spend / number of conversions. If you spent 500 dollars for 25 conversions, your CPA is 20 dollars.
What is the difference between CPA and CPL?
They use the same formula. CPL usually refers to leads (form fills), while CPA refers to a completed action such as a sale.
How do I know if my CPA is profitable?
Compare CPA to the payout or lifetime value of each conversion. If your payout is higher than your CPA, the campaign is profitable.
