FAQ
How do CPM, CTR and conversion rate turn into CPA?+
CPM is what 1,000 impressions cost. Click-through rate sets how many of those impressions become clicks, which gives cost per click. Conversion rate sets how many clicks become orders, which gives cost per acquisition.
Why does a small change in conversion rate matter so much?+
CPA is cost per click divided by conversion rate. Going from a 1 percent to a 2 percent conversion rate halves what each order costs to acquire.
Does this include repeat purchases?+
No. It measures the first order only. If customers come back, a first order that loses money can still pay off. Use the customer lifetime value calculator to size that.
