Frequently asked questions
What is break-even CPA?
The ad cost per purchase at which an order earns exactly nothing: your price minus every other cost of the order. It's the profit per order shown here.
CPA or ROAS?
Both say the same thing: a CPA under your break-even CPA is a ROAS above your break-even ROAS. Use the one your ads manager reports.
How do I improve these numbers?
Fresh creatives are one of the levers you fully control. Adsmithy makes new ads from your product photo, so you can test more of them.
Is what I type stored?
