What is cost per order?

Cost per order (CPO) is the ad spend required to generate one order. Compared against the profit each order earns, it tells you if acquisition is sustainable.

Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.

CPO vs profit per order

$ per order

The same $22 CPO loses money on thin SKUs and prints profit on heroes — why blended CPO targets mislead.

CPO in context

A $22 CPO is great if orders earn $60 profit and terrible if they earn $15. The number is meaningless without the profit comparison.

This is why profit-first teams track CPO against contribution margin per order, not against AOV or a fixed target.

Levers on CPO

CPO moves with the same funnel math as CPA:

  • Lower CPC via relevance and Quality Score.
  • Raise conversion rate to spread spend across more orders.
  • Improve targeting to reduce wasted spend.
  • Bid on profit so CPO scales with each order's margin.

Frequently asked questions

Common questions about this topic — tap to read answers.

Is CPO the same as CPA?

Often, yes, when a conversion equals an order. CPA can also count leads or signups; CPO specifically counts purchases.

What CPO can I afford?

Up to your per-order contribution margin, minus the profit you want to keep. Higher-AOV or higher-margin orders support a higher CPO.
