Why AOV Is the Right Metric to Optimise
Every WooCommerce store has three growth levers: traffic, conversion rate, and average order value. Traffic is the most expensive to increase. Conversion rate is the most constrained (you can only convert as many visitors as your product and UX allow). AOV is often the most accessible — a well-configured promotion can increase AOV by 15–30% without any traffic or conversion investment.
But AOV growth has a trap: unconditional discounts (10% off everything) often reduce revenue per order without increasing item quantity. The goal is to create conditional discounts that give customers a specific reason to buy more.
Bulk Pricing: The Most Reliable AOV Tool for Physical Products
Bulk pricing — tiered quantity discounts — works because it aligns the store's interest (higher order value) with the customer's interest (lower per-unit cost). A customer who buys 1 unit gets no discount. A customer who buys 5 units gets 8% off. The economics of the deal improve as quantity increases.
Key rule: set the first tier threshold above the typical order quantity for that product. If most customers buy 1–2 units, the first tier should be at 5 units. If most buy 5–10, the first tier should be at 12–15.
Display a bulk pricing table on the product page. Customers who see a better price at 5 units before they add to cart will often add 5 instead of 2. Customers who discover the deal only at checkout rarely change their cart.
Cart Discount Threshold: The Fastest AOV Win
A cart discount threshold — "spend $80, get 10% off" — is the most direct AOV-increasing tool. It creates a specific monetary target that some percentage of customers will reach to unlock the discount.
The mechanism: a customer with $62 in cart sees "Add $18 more to save 10%." The $10 saving on a potential $80 order is concrete and immediate. Many customers will add an item they were considering — or add something they weren't — to reach the threshold.
Set the threshold 20–30% above your current AOV. Use a cart progress bar to make the remaining amount visible. Without visibility in the cart, few customers know the offer exists until they reach checkout — too late to change their purchase decision.
Buy X Get Y: AOV Through Cross-Sell
Buy X Get Y increases AOV differently from bulk pricing and cart thresholds. Instead of increasing quantity of existing planned purchases, it adds a new item (the reward product) to the cart.
The AOV effect works if the reward product is at a partial discount — say, 30% off rather than free. A customer who adds a $25 accessory at 30% off ($17.50) to a $60 main purchase produces a $77.50 order — an AOV increase of $17.50.
For AOV growth (rather than loyalty or cross-sell awareness), the reward product should be priced so that the customer perceives value in adding it, but the store maintains margin. A reward product at 30–40% off with reasonable margin on the qualifying product works better than a free reward that erodes margin.
Buy X Get X: AOV Through Quantity Rewards
Buy X Get X at higher qualifying quantities produces AOV growth in the same way as bulk pricing, but with a different presentation. "Buy 3 get 1 free" is equivalent to 25% off when you buy 4 — but customers often perceive "get 1 free" as higher value than "25% off."
BXGX is particularly effective for products where customers have a replenishment mindset — skincare, supplements, cleaning products — where buying a larger quantity now saves a future purchase.
Combining AOV Strategies: The Stacking Risk
Running a bulk pricing promotion and a cart discount simultaneously can produce compounding AOV effects — or compounding margin loss, depending on configuration.
If a customer gets a 15% bulk discount on a product and then the cart hits the $80 threshold for a 10% cart discount, the effective discount on the bulk-discounted items is ~23.5% (15% + 10% applied sequentially), not 25%. Still compound discounting, just slightly less than additive.
Configure stacking controls to match your intent. If both promotions can apply to the same order, model the effective discount on your lower-margin products before publishing both simultaneously.
What Doesn't Increase AOV
- Flat percentage discounts with no threshold — 10% off everything gives customers no reason to add more items. It just reduces revenue on existing purchases.
- Cart thresholds too close to current AOV — if most customers naturally reach $75 and you set the threshold at $80, you're rewarding existing behaviour, not changing it.
- Bulk pricing tiers starting at the typical purchase quantity — same problem: rewarding existing behaviour without producing incremental order value.
- BXGY with an unappealing reward — a reward product the customer doesn't want won't add to AOV, regardless of the discount depth.
Measuring AOV Impact
Compare average order value for orders that included the promotion against the baseline using Ezhance promotion analytics. A 10–15% AOV increase in the promoted population is a meaningful result. Less than 5% suggests the threshold or tier structure needs adjustment.
Also look at conversion rate on the promoted product pages. Bulk pricing tables and cart progress bars can increase conversion rates as well as AOV — especially on products where customers were previously uncertain about quantity.
