Definition
AOV (Average Order Value) is your total revenue divided by the number of orders in a given period. It's what an average customer puts in the cart per purchase.

Why AOV is a lever, not a report
AOV is easy to overlook because it doesn't live in the ad account. But it's one of the strongest levers you have: raise AOV by 15% without touching the marketing budget, and both contribution margin and the CAC you can afford to pay go up.
Bundling, volume discounts, free shipping above a threshold and smart cross-sell at checkout are among the cheapest growth initiatives there are. They cost no extra ad euros.
AOV in the bigger equation
AOV feeds straight into CLTV: higher order value × number of purchases = higher customer value. And because a higher AOV improves the economics per order, you can bid higher in the auction and still hit your POAS target. That's how a seemingly small checkout improvement can unlock a whole new scaling ceiling.
The math behind a lift in AOV
Put numbers on it: AOV is €65 at a 45% margin — roughly €29 in contribution margin per order. If your CAC is €26, there's €3 left per new customer on the first purchase — thin. Raise AOV to €75 (+15%) without touching the ad budget, and contribution margin climbs to ~€34, so suddenly there's €8 left. You've more than doubled the profit per new customer without a single extra ad euro.
That lift propagates all the way up. Higher contribution margin per order lowers your break-even ROAS, which means campaigns that were marginal before are now profitable — and you can bid higher in the auction and win traffic the competitor has to leave on the table. That's how a checkout optimization becomes an ad ceiling.
The cheapest levers are rarely discounts: free-shipping thresholds set just above your current AOV, bundles and product sets, volume discounts on consumables, and relevant cross-sell in cart and checkout. Discounts lift AOV too, but they eat the very margin the lift was meant to create — use them deliberately, not by default.
Frequently asked questions
How do I raise AOV without discounting?
Bundles and product sets, free-shipping thresholds set just above your current AOV, cross-sell of accessories at checkout, and highlighting the more expensive variant. Discounting is only one route — and rarely the most profitable one.
