# A/B Testing for Upsell Offers

# ${color}[#204a87](A/B Testing for Upsell Offers)

A/B testing lets you show two or more versions of an upsell offer to your customers and see which one sells better. You don't have to guess. For example, if a customer just bought skis, you could show one group of customers **ski goggles** and another group **ski gloves** — then let the results tell you which offer works best.

You can run an A/B test on **any offer block** on these pages:

* **Checkout**
* **Post-purchase**
* **Thank You**
* **Order Status**

| Checkout page offers are only available with a Shopify Plus subscription due to Shopify plan [limitations](https://help.shopify.com/en/manual/checkout-settings/customize-checkout-configurations).


Each version of the test tracks its own **Impressions, Clicks, Conversion rate, and Revenue**, so you can see exactly how it performs.

# ${color}[#204a87](Starting an A/B Test)

1. Open your funnel and go to the offer block you want to test (for example, **Upsell Offer 1** on the Checkout step). The block needs to already have a product, collection, automatic, or add-on offer configured.
2. Click the **⋯ (three-dot)** menu on that offer block.
3. Hover over **Create A/B test**, then pick how the second version should be created:
    * **Duplicate** – copies the current offer as-is
    * **Product** – pick a different product
    * **Collection** – pick a collection
    * **Auto** – let Shopify recommend a product automatically
    * **Add-on** – add an add-on offer

This creates an **A/B test** panel with **Version A** and **Version B** cards side by side. Version A is your original offer and starts as **Active**; Version B starts as **Inactive**.

# ${color}[#204a87](Adding More Versions)

Need to test more than two options?

Click **+ Add Version** above the version cards to add Version C, D, and so on, using the same offer-type choices (Duplicate, Product, Collection, Auto, Add-on).

Each version card has its own **⋯ (three-dot)** menu where you can change what it offers (**Change product**, **Collection offer**, **Automatic offer**, **Add-on offer**), **Copy offer**, or **Delete** it — as long as the test isn't currently running.

# ${color}[#204a87](Setting the Traffic Split)

Click the **⚙️ gear icon** next to **Add Version** to open the **Impression percentage** window. Drag the slider to decide what share of visitors sees each version (for example, 50% / 50%, or 33.3% each for three versions), then click **Save**.

If you pause or delete a version later, the remaining versions automatically split its share of traffic between them.

# ${color}[#204a87](Running the Test)

Click **Start** to launch the test.

* Your funnel must be **published** first. If it isn't, a **Publish required** window appears telling you the funnel needs to be saved and published before the test can start — click **Save & Publish** to continue.
* Once the test starts, the **Start** button becomes **Stop**, and every version's status changes to **Testing**.
* While a test is running, editing is locked: **Add Version** and the percentage settings are disabled, and each version's **⋯ (three-dot)** menu is grayed out. The only action available is **Stop**.

All impressions, clicks, conversion rate, and revenue numbers update in real time and also feed into your overall funnel analytics.

# ${color}[#204a87](Stopping the Test and Picking a Winner)

Click **Stop** to end the test. A **Select winner** window opens showing every version that took part, each with its offer preview and live metrics (Impressions, Clicks, Conversion rate, Revenue).

The app automatically highlights one version with a **Recommended winner** badge, based on its performance (for example, highest revenue or conversion rate). It's pre-selected, but you can click any other version to pick it instead — only one version can be chosen.

Click **Save** to confirm. The version you picked becomes **Active** and stays live on the page; every other version switches to **Inactive**. The test panel resets and the **Stop** button turns back into **Start**, so editing (Add Version, percentage split, per-version offer changes) is unlocked again — meaning you can adjust versions and launch another round whenever you like.
