AOV is one of the three numbers that determine e-commerce revenue: traffic, conversion rate, and AOV. Move any of them up and revenue goes up. AOV often gets the least attention because it feels less actionable than traffic or conversion, but it is usually the cheapest lever to pull.
AOV = Total Revenue ÷ Number of Orders
If a store does $50,000 in revenue across 500 orders in a month, AOV is $100.
Higher AOV means each customer acquisition pays back faster. If your customer acquisition cost is $25 and your AOV is $40, the unit economics are tight. If you can lift AOV to $60 through bundle pricing, threshold-based free shipping, or smarter cross-sells, the same ad spend suddenly works.
AOV also reveals pricing health. A falling AOV in a stable category often signals that customers are gravitating to your cheapest items, a sign that mid- and premium-tier prices may be uncompetitive.
Example: A homewares store notices AOV has dropped from $85 to $68 over six months. Investigating, they find competitor prices have risen on entry-level items but their own remained flat, pulling traffic toward the cheap end of the catalogue. Repricing the entry-level SKUs upward (still beating competitors but no longer dramatically below them) brings AOV back up.
