Product Price Testing in GemX allows you to compare your current product price with a different price and determine which one delivers better results. You can test one product or a group of products, allocate traffic between two prices, and compare performance metrics such as Revenue and Conversion Rate.
This guide explains how to create, preview, and launch a Product Price Testing experiment in GemX.
What Is Product Price Testing?
A Product Price Testing experiment compares the following two versions:
-
The Control (Original) is the product with its current price. This version serves as the baseline for the experiment.
-
The Variant is the product version with the price that you want to test against the Original.
GemX distributes eligible visitors between the Original and Variant according to the traffic split that you select. As the experiment collects data, GemX Analytics shows how each price performs and helps you make a pricing decision based on actual customer behavior.
Product Price Testing is available on both Page Optimize and Funnel Optimize plans.
Before You Start
Before you create an experiment, make sure that:
-
Your Shopify store has GemX: CRO & A/B Testing installed and activated.
-
You have a clear pricing hypothesis and know which price you want to test. If you need help defining your hypothesis, refer to How to Run a Test From My Hypothesis.
-
The product that you want to use as the Control has an Active status and is available on the Online Store sales channel.
-
You have decided whether GemX should duplicate the Control or whether you want to use an existing product as the Variant.
Important note: The price should be the only difference between the Control and Variant. Both products should use the same title, description, images, options, and other product information so that the experiment can isolate the impact of the price change.
How to Set Up a Product Price Testing Experiment
Step 1: Create a New Experiment
From your Shopify Admin, open Apps > GemX: CRO & A/B Testing and click Create new experiment.
Then select Product Price Testing as the experiment type.
GemX will create a new Product Price Experiment with the Draft status.
Step 2: Select the Control Product
In the Product price setup section, select the product whose current price will serve as the baseline.
You can search or browse the product list to find the appropriate product, then click Select product.
Important note: GemX only displays products that have an Active status and are available on the Online Store sales channel.
After you select a product, GemX will add it to the experiment as the Control.
Step 3: Set Up the Variant Product
The Variant contains the price that you want to compare with the Original. GemX provides two ways to prepare this product.
Option 1: Duplicate the Control and Set a New Price
This option is suitable when you have not prepared a separate Variant product.
Select Duplicate Control to let GemX automatically duplicate the selected Control product and set it as the Variant one.
Duplicate the Control product to create a price-test Variant.
From here, you can click Edit price to access the duplicate in a new tab. When the Shopify product page opens, update the price for the product or its individual variants.
Once done, click Save in Shopify, and return to GemX to continue the experiment setup.
Important note: Do not change other product information on the duplicate. The test price should be the only difference between the two products.
Option 2: Choose an Existing Product
This option is suitable when you have already prepared a separate product with the price that you want to test.
Select Choose existing product, then search for and select the appropriate product.
You can click Edit price to open the product in Shopify and check its current pricing.
If you update the price, click Save in Shopify before returning to GemX. You should also confirm that the selected product matches the Control in every aspect other than price.
Step 4: Review the Experiment Settings
The settings panel at the top of the experiment shows how GemX will run the test. By default, the experiment displays the following settings:
-
The Winning metric is Revenue.
-
The Traffic split assigns 50% to the Original and 50% to the Variant.
-
The Device setting includes all devices.
-
The Visitor setting includes all visitors.
-
The Traffic source setting includes all sources.
-
The Market & language setting includes all markets.
If you want to change the traffic allocation, click the edit icon next to Traffic split. You can then move the slider to adjust the percentage of eligible visitors assigned to each version.
A 50/50 split usually provides the most balanced comparison because both versions collect data at a similar rate. To understand other allocation options, refer to How Does Traffic Splitting Work in GemX?.
Step 5: Save and Preview Both Versions
After both products are ready, review their names, Shopify links, and displayed prices. Click Save when all information is correct.
Before you launch the experiment, use Preview to inspect both the Original and Variant.
During the preview, confirm that:
-
Each version displays the intended product price.
-
Every product variant displays the correct price.
-
Customers can add the product to their cart successfully.
-
The cart and checkout display the expected price.
-
No product information other than the price has changed unintentionally.
If you identify an issue, return to Shopify to correct the product before starting the campaign.
Step 6: Start the Experiment
When both versions are ready, click Start experiment. The confirmation dialog will display the experiment information for one final review.
After you confirm, GemX will start the experiment and distribute eligible visitors between the Original and Variant according to your traffic split.

Manage Your Product Price Experiment
After the experiment goes live, GemX Analytics allows you to compare the Original and Variant using Revenue, Conversion Rate, and other available metrics.
Try to keep both products unchanged while the experiment is active. Additional product changes can introduce new variables and make the results more difficult to interpret.
