12 Proven Ways to Increase Average Order Value

Web and E-Commerce, 10 min read. By Sefa Aydın. Last updated: September 16, 2026

E-commerce growth has three levers: more visitors, a higher conversion rate and a bigger basket. The first two require either ad budget or a long optimization process. The third is money most brands leave on the table, because getting a customer who has already decided to buy to add one more product is many times cheaper than finding a new customer from scratch.

In this guide we explain how average order value is calculated, why it grows profit without lowering customer acquisition cost, and the 12 methods that grow the basket, with concrete TL examples. At the end you will find measurement, A/B testing and the traps that erode your margin. Filter each method through your own category, and instead of applying them all at once, start with the two or three that have the highest impact.

What Is Average Order Value (AOV) and How Do You Calculate It

Average order value is total revenue in a given period divided by the number of orders in the same period. If you made 1,000 orders and 500,000 TL in revenue in a month, your AOV is 500 TL. Decide once whether you include shipping revenue and VAT in the calculation, otherwise month-to-month comparisons break. For a healthy reading, track AOV across three breakdowns: new vs returning customers, device (mobile baskets are usually smaller) and traffic source. These breakdowns show which method will work where.

AOV alone is not a sufficient metric and should be read together with gross profit per order. A campaign that grows the basket by 20% but cuts margin by 30% looks like a success on the AOV chart and a loss on the profit sheet.

Why AOV Grows Profit Without Lowering CAC

A higher AOV grows profit because ad costs are paid per order, not per basket size. When you earn more revenue from each order with the same ad budget, the same clicks and the same number of orders, most of the additional revenue goes straight to profit. The example below shows a brand whose 500 TL AOV rises by 15% to 575 TL.

The example is hypothetical and excludes VAT, shipping and returns. Try your own numbers in the e-commerce profitability calculator.

While revenue grew by 15%, profit after ad spend grew 2.3 times, from 12,500 TL to 29,375 TL. This leverage moved ROAS from 2.5x to 2.9x without buying a single extra click. Capturing the same 15% growth with new customers would have required 15,000 TL in extra ad budget plus the assumption that CAC stays flat, and in competitive periods like November that assumption rarely holds. For the full unit economics, see the CAC and LTV guide.

Methods 1-4: Thresholds and Bundle Design

The first four methods are the most natural ways to tell a customer "add a little more", and in most brands they deliver the fastest results.

1. Free shipping threshold

Set the threshold roughly 20-30% above your current AOV. If AOV is 500 TL, 600-650 TL is the right starting point. Set the threshold too high and customers give up, set it too low and you give free shipping to people who would have bought anyway. A "120 TL away from free shipping" bar in the cart is the engine of this method. With a threshold but no bar, you lose half of the effect.

2. Product bundle

Bundle three products that are used together at one price and show a 10-15% advantage over buying them separately. In skincare, think cleanser, toner and moisturizer, and in sports, a mat, a resistance band and a water bottle. A bundle both grows the basket and reduces decision fatigue. Replacing the lowest-margin product in the bundle with a low-cost complementary item protects your margin.

3. Gift threshold

A setup like "free travel-size product with orders over 1,000 TL" creates the same effect as a percentage discount at a lower cost. A gift that costs 40 TL is a 4% margin loss on a 1,000 TL basket, whereas a 10% discount costs 100 TL. Make the gift a product the customer has not tried yet, and you also plant the seed for the next order.

4. Tiered discount

Tiers like "10% off over 1,500 TL, 15% off over 3,000 TL" move customers up a step. Build the tiers around your AOV distribution: put the first tier just above the amount where orders cluster, and the second tier at the distance where a customer who reached the first tier would add one more product.

Methods 5-8: Recommendations and Limited Offers

This group works in situations where the customer cannot know what to add to the basket unless you show them.

5. Cross-selling

A "frequently bought together" block on the product page and in the cart works best with complementary, lower-priced products. A screen protector with a phone case, filters with a coffee machine. When the recommended price is within 10-30% of the main product, the add rate rises noticeably. Recommend what is actually bought together, not random "popular products".

6. Upselling

You offer a bigger size, a higher model or a 2+1 variant of the same product. The message "Get 1 liter instead of 500 ml and save 25% per milliliter" is persuasive when it comes with a numerical comparison. Upselling happens on the product page, not in the cart, because in the cart the customer has already made a decision and disrupting it is risky.

7. In-cart recommendations

The cart page should have a single recommendation row, limited to 3-4 products and addable with one click. Showing "products that complete the threshold" to a customer close to the free shipping threshold is the strongest application of this method. A 10-product recommendation strip in the cart, on the other hand, distracts and lowers the move to checkout.

8. Limited editions and time-limited bundles

A special set produced in limited numbers or a bundle price valid only this week brings the decision forward and adds extra products to the basket. This method works only if it is genuinely limited. If "last 3 items" stays the same every day, customers notice and trust in the brand drops.

Methods 9-12: Payment, Loyalty and Proof

The last four methods support basket growth through payment convenience and trust.

9. Installments and buy now pay later

Showing the monthly installment amount on the product page grows the basket for higher-priced products. When a 3,000 TL product is presented as "500 TL a month in 6 installments", the customer moves more easily to a higher model or a second product. Do not forget to include the installment fee in your margin calculation.

10. Subscription

For consumables, a subscription grows not only AOV but also customer lifetime value. For regularly consumed products such as coffee, supplements and pet food, a "subscribe and save 10%" option turns one-time buyers into year-round customers. Keep cancellation easy, otherwise it turns into a trust problem that backfires.

11. Loyalty points

A message like "You will earn 150 points on this order, and 200 points equal a 100 TL discount" creates its own reason to add one more product to the basket. The link between the points system and AOV is made when the points are spent on the next order. You will find the setup details in the article on customer loyalty and CRM strategies.

12. Social proof on the product page

Review count, rating and "customers who bought this also bought" information let the customer move with confidence to a higher-priced option or a complementary product. Social proof does not look like a direct AOV method, but it determines the conversion rate of the other 11 methods. We cover product page optimization in the conversion rate optimization guide.

Measurement and A/B Testing

In AOV work, decisions should rest on a controlled test, not on a single week's chart. Every change, such as moving the free shipping threshold from 600 TL to 700 TL, should be shown to two groups at the same time and tested for at least two weeks with meaningful order volume. The three metrics to measure are AOV, cart-to-checkout rate and gross profit per order. If AOV rises while the move to checkout falls, you have raised the threshold too much. You can see what cart abandonment costs you in the cart abandonment loss calculator.

Read the test by day of week and campaign period. AOV naturally rises in payday week, so do not credit that increase to your method. Likewise, do not expect a basket that grew during a November campaign to hold in December, and always compare periods of the same kind. Once you make the winner of the test permanent, move to the next method. Testing two methods at the same time makes it impossible to see which one worked.

An offer that grows the basket does not tell the customer "spend more", it says "get more for this price".

Traps: Discounts That Erode Margin and More

Most AOV methods lower profit instead of raising it when set up wrong. Check this list before you apply them:

• The discount tier was built with a margin calculation. If a 3,000 TL basket at 15% off leaves less profit than a 2,000 TL basket at 10% off, the tier is wrong.
• The free shipping threshold was calculated from average shipping cost and your current AOV distribution, not by looking at competitors.
• The bundle price includes the margin of each product in the bundle, and the total margin is not lower than selling them individually.
• Cart recommendations do not slow down the checkout step and can be added with a single tap on mobile.
• Gift and discount setups are reversed on returned orders, otherwise a wave of returns erodes your margin a second time.
• There is no permanent discount. A brand that runs a tiered campaign every week teaches customers that the non-campaign price is not real.
• Cart abandonment rate is tracked alongside AOV growth. If abandonment is rising, clear the friction first with the steps in the cart abandonment guide.

Growing average order value is the only growth lever that does not depend on ad budget, and in most brands thresholds, bundles and recommendations alone deliver measurable results within the first month.
