This article walks you through how to apply the winning template from your experiment in GemX safely. Once your experiment has collected enough data and GemX identifies a clear winner, you can publish that version to your live store in just a few clicks.
What It Means to Apply a Winning Template
When you apply a winning template, GemX replaces the current live template with the version that performed better during the experiment. This lets you deploy the best-performing design without manually updating the page.
Important notes:

Before You Apply the Winner
Before selecting the winning template, review your results to confirm that the outcome aligns with your CRO goals.
In the summary bar, GemX highlights:
-
The winning version (Control or Variant)
-
The primary metric used to determine the winner (e.g., Conversion rate)
-
Whether other metrics are similar between versions (AOV, Revenue per visitor, etc.)
-
Probability to win for each version
Once you are confident in the results, continue to apply the winner.
How to Apply the Winning Template
Step 1: Access Your Experiment Analytics
From the GemX dashboard:
-
Go to Experiments tab
-
Open the experiment you want to finalize
-
At the top of the report, you’ll see a summary such as: “Control wins on Conversion rate".
This indicates which version performed best.
Step 2: Click Make winner
On the right side of the summary bar, click Make winner.
Once you click Make winner, GemX displays a detailed summary of how each version performed. 
This section helps you double-check and confirm the winning version truly aligns with your testing goal before applying it.
Step 3: Choose the Winning Template
Click Choose winning template.
A confirmation dialog will appear. This modal shows both versions side by side so you can review and select which template you want to publish as the final winner.

Step 4: Verify the Update on Your Storefront
To make sure the winning version is applied correctly:

Open the page on your storefront

Check desktop and mobile views

Confirm that key functions still work (Add to Cart, navigation, images, etc.)
This ensures everything is working exactly as expected after publishing.
