Questions
Cost per acquisition: total ad spend divided by the orders it produced. If you spent $1,200 on ads for 100 orders, CPA is $12.
Return on ad spend at which a sale makes exactly zero profit: revenue ÷ ad spend. A product with $49.99 price and $20 contribution breaks even at 2.5× — every dollar of ads must bring back $2.50 of revenue.
