# Order Confirmation Page Product Suggestion A/B Test

Page: https://alidemirbas.com.tr/en/lab/ab-test-library/tests/order-confirmation-page-product-suggestion-ab-test

## Hypothesis

If buyers who have just completed an order see related products on the confirmation page, some may find a reason to place another order. The additional purchase rate over the fixed follow-up window could increase, though the recommendations may compete with the confirmation details for attention.

## When to run this test

Customers who come back soon after ordering for related products, or support requests asking to add an item to an order already placed, suggest buyers still want complementary items after checkout. When the recommendations land, some buyers pick one and complete a second order separate from the first. If the requests are about adding items to the original order, look at an order-editing option first. Do not show guest buyers an account-creation prompt on this page during the same test; it is a separate variable, and you would not be able to tell the two effects apart.

## Primary metric

**Additional purchase rate**: Measure completed additional orders per assigned order-confirmation page visitor over a fixed follow-up window.

## Other metrics

- **Value of additional orders**: Report the value of completed orders that are separate from the original order.
- **Order summary access**: Track whether users open the order summary after seeing recommendations; order details must remain visible.
- **Order-related support requests**: Compare questions about order status or tracking using the same denominator.
- **Confirmation-page exit rate**: Interpret exits alongside access to order information; leaving after confirmation can be normal.

## What to check before and during the test

- **Change**: Add a related-product recommendation module to the order-confirmation page.
- **Keep constant**: Leave the order summary, delivery details and confirmation content unchanged.
- **Behavior**: Review recommendation interactions alongside completed additional orders.
- **Order information**: Do not let the module obscure the order confirmation, number or delivery information.
- **Separate tests**: Test placement, recommendation count and recommendation logic separately.

## What to watch when reading the result

- Clicks on recommendations or started orders do not decide the test; count only additional orders completed within the fixed window. Report the value of additional orders separately from the original order, and do not read confirmation-page exits as bad on their own, since leaving after an order is normal.
- If order-related support requests or order summary access change, the module may be confusing buyers. Confirm the recommendation card can be dismissed, that the confirmation is reachable without getting past it, and that a purchase started from it does not suggest the original order still needs payment.
- Treat the outcome as specific to the module, placement and product-selection logic you tested; a different recommendation algorithm or count is its own experiment. Validate it again in context before moving it to other post-purchase screens.
- Should the difference stay unclear, note that this sample could not separate a change in additional orders, rather than reporting that the module had no effect. Once the follow-up window closes, enter each arm's confirmation-page visitors and buyers who completed another order into the [A/B test significance calculator](https://alidemirbas.com.tr/en/calculators/ab-test); it shows whether the gap is beyond chance. It does not test averages, so treat any difference in the value of additional orders with the same caution.

## Frequently Asked Questions

### What must recommendations leave unchanged on confirmation pages?

Preserve the order summary, number, delivery details and main confirmation content. Make the recommendation strip dismissible. Do not imply the completed order still requires another payment step.

### Do more recommendation clicks mean success?

No. Use the share of assigned confirmation-page visitors completing an additional order within a fixed window. Count completed orders, not starts, and report additional revenue separately from the original order.

### Is leaving the confirmation page a negative signal?

Not by itself. Assess access to order details and compare order-related support contacts using a common denominator. Summary openings can provide diagnostic context.
