How it works
CPA = cost ÷ conversions
Highest affordable CPA = average order value × margin
At €85 per order and a 40% margin, a sale can cost up to €34 in ads before it loses money.
For leads, use what a lead is worth instead: the share of leads that become customers, times what a customer is worth to you.
Read CPA per campaign, not for the whole account. Brand campaigns pull the account average down and hide what non-brand search really costs.

What is a good CPA in Google Ads?
One below what a conversion is worth to you. An industry average says nothing about your margin, so compare your CPA with your own highest affordable CPA.
Is CPA the same as cost per conversion?
In Google Ads, yes: cost divided by conversions. CPA is the name used for the target in Smart Bidding.
