How to Set Up a Product Upsell Test at Checkout

Steps to testing no products vs. 3 products vs. 1 product upsell at checkout

No Upsell vs. 3 Products vs. 1 Product

Adding upsells to your checkout page is easy with Intelligems. You have the power to not only show upsells to customers at checkout without needing another app, but you can test and measure the impact of product upsells. In this example, you can test no upsells vs. showing 3 products vs. showing 1 product at checkout.

Who is this for

This test is best for:

• Brands with accessories or easy add-on products

• Teams new to checkout upsells and wanting to validate impact

• Growth teams wanting to understand if there's tradeoff between conversion and AOV

What this Checkout Test does

This setup creates a Product Upsell Checkout test that compares different upsell strategies at checkout.

Specifically, this test allows you to compare:

• A control (no upsells)

• Showing 3 product upsells

• Showing 1 product upsell

The goal is to understand how the number of upsell products shown at checkout impacts performance. This can lead to more follow up tests like position of the checkout upsell, products included in the checkout upsell, and more.

When to use it

Use this setup when you want to :

• Test whether showing product upsells at checkout drives incremental value

• Compare the impact of one product vs. multiple products

• Introduce checkout upsells in a controlled, test-first way

• Understand how much choice is appropriate at checkout

Pro Tip: Choose products that are one size, and are obvious add-ons. This should feel like a no-brainer add on, similar to gum in the checkout line at the supermarket. Minimal decision making for the customer.

Why it matters

Checkout is the highest-intent moment in the purchase journey, but it’s also highly sensitive to friction. Testing one product versus multiple products helps you find the right balance between increasing average order value and maintaining conversion.
