AOV (Average Order Value)
AOV (average order value) is the average amount spent per order, calculated as total revenue divided by the number of orders.
AOV (average order value) is the average amount a customer spends per order, calculated as total revenue ÷ number of orders. If 200 orders generate $10,000 in revenue, the AOV is $50.
AOV is a deceptively powerful lever in paid advertising because it directly sets how much you can afford to pay for a customer. The higher your AOV, the more headroom you have on click costs and acquisition costs while staying profitable.
Why it matters#
AOV ties together your top-line and your unit economics. It's a key input to both ROAS (Return on Ad Spend) and your break-even CPA (Cost Per Acquisition): a higher AOV (at the same margin) raises the CPA you can profitably tolerate, which in turn lets you bid more aggressively and win more traffic than competitors stuck at a lower order value.
This is why media buyers and advertisers invest heavily in raising AOV through upsells, bundles, order bumps, volume discounts, and free-shipping thresholds. Lifting AOV improves campaign economics without needing a better Conversion Rate (CVR) or cheaper clicks; the same traffic simply becomes worth more.
A practical way to read it: two advertisers can run identical ads and bid identical amounts, but the one with the higher AOV will out-earn the other on every single sale, and can outbid them as the campaign scales.
