AOV means average order value. Add up the revenue from all orders in a period and divide by the number of orders. A store that took 500 orders worth 30,000 in total has an AOV of 60.
It is a core ecommerce number and appears in Shopify, GA4 and most store dashboards. AOV is measured per order, not per customer, so one shopper who buys three times counts as three orders.
AOV matters to advertisers because it sets how much an order can absorb in acquisition cost. Together with conversion rate, it decides how much revenue each visitor brings, and that in turn decides how much you can pay per click and still make a profit.
Mechanics
What moves average order value
Product mix is the first driver. If traffic lands mostly on low priced items, AOV stays low no matter how good the checkout is. Promoting bundles, larger pack sizes or premium versions shifts the mix upward.
Store mechanics come next. A free shipping threshold set a little above the current AOV nudges shoppers to add one more item. Product recommendations in the cart, volume discounts and gift sets work the same way.
Discounts pull in the other direction. A sitewide sale can lift order count while each order gets smaller, so AOV drops even as revenue rises. Traffic source matters as well: people arriving from a search for a specific product often buy just that product, while returning email subscribers may fill a larger basket.
Example
A worked example with a shipping threshold
Assume a pet supply store took 1,200 orders last month worth 54,000 in revenue, an AOV of 45. Free shipping currently applies above 40, so most orders already qualify and the threshold does little.
The store raises the threshold to 60 and adds a cart suggestion for treats and toys. Say the following month brings 1,150 orders worth 59,800, an AOV of 52. Order count fell slightly, but revenue rose by 5,800.
Now link it to advertising. If the store keeps 35 percent of revenue as gross profit, an order at 45 leaves 15.75 to pay for ads, while an order at 52 leaves 18.20. With a conversion rate of 2 percent, the break-even click price moves up by about 0.05, which lets campaigns bid a little higher on the same keywords without losing money.
Use
When AOV helps and when it misleads
- Use it to set affordable acquisition costs and bid limits, since the value of a typical order caps what a click or a conversion is worth.
- Use it to judge store changes such as bundles, thresholds and cart suggestions, reading it next to order count and total revenue.
- It misleads when a few very large orders pull the average up; the median order value shows what a typical shopper really spends.
- It misleads if returns and cancellations are not removed, because refunded orders still sit in the average.
Watch out
Common mistakes with AOV
- Celebrating a higher AOV while total orders drop enough that revenue and profit fall.
- Mixing wholesale or B2B orders with retail ones, which produces an average that describes neither group.
- Reporting AOV with tax and shipping in some months and without them in others, so trends reflect a change of definition.
- Treating AOV as customer value; it covers one order only, and repeat buying is what LTV measures.
