This article walks you through how to install GemX: CRO & A/B Testing on your Shopify store and get started with your 14-day free trial.
What is GemX: CRO & A/B Testing?
GemX is an A/B testing and CRO (Conversion Rate Optimization) app designed for Shopify merchants. It allows you to test different versions of your store’s pages to find out what works best — based on real customer behavior.
You can test changes in layout, messaging, product display, images, CTA buttons, and more. Instead of guessing what might improve sales, GemX lets you use data to drive every decision.
GemX is part of the GemCommerce ecosystem, developed by the team behind GemPages. GemX works on any Shopify store, with or without a page builder.
What You Can Do with GemX?
GemX is built to help merchants at any stage of growth, from small stores looking for their first conversion uplift to larger brands optimizing at scale.
Here’s a breakdown of what you can test and optimize:
1. Template Testing for Quick Wins
With GemX Template Testing, you can test different versions of a single page.
For example:
-
Product page layout A vs. layout B
-
Different hero sections
-
Alternative pricing block structure
-
Variant-specific messaging strategy
This is ideal for:
-
High-impact product page optimization
-
Collection page redesign validation
-
Homepage layout experiments
Instead of editing live templates manually, you test them in parallel and measure real performance differences.

2. Multipage Testing for Full-funnel Experiment
E-commerce conversions rarely happen on a single page, and your customers move through:
| (1) Product page → (2) Cart → (3) Checkout → (4) Thank you page |
GemX Multipage Testing allows you to test changes across the entire funnel rather than isolating a single page.

For example, you can use GemX Multipage Testing to:
-
Test a new product page layout and updated cart design
-
Test bundle messaging across multiple steps
-
Evaluate a new funnel experience for paid traffic
-
Run experiments across your homepage, collection pages, and product pages
-
Create end-to-end funnel tests that measure performance across the customer journey
This approach is especially powerful for stores focused on improving the checkout completion rate, revenue per visitor, and funnel drop-off reduction.

3. Make Confident Decisions with Built-In Analytics
A/B testing only drives growth if you can read the data correctly. That’s why GemX doesn’t stop at traffic splitting. Besides, it provides a complete built-in analytics layer designed for Shopify e-commerce.
Instead of stitching together reports from multiple tools, you get structured insights across deep analytics modules:
Experiment Analytics (Your Test Reports)
See control vs. variant performance side by side with conversion rate, revenue, revenue per visitor, traffic distribution, and statistical confidence. This is where you validate winners with clarity, not assumptions.

Page Analytics
Analyze the performance of any store page, even outside active experiments with GemX Page Analytics. Identify underperforming product pages, high-bounce landing pages, and friction points before turning insights into new A/B testing hypotheses.

Order Analytics
GemX Order Analytics helps you track order-level impact across experiments, including revenue trends and purchase behavior shifts. This helps you evaluate not just conversion lifts, but actual revenue impact.

Metric Analytics
GemX has the built-in detailed analytics for any store metrics, so that you can monitor core ecommerce KPIs in a structured format that supports ongoing optimization decisions.

Journey Analysis
Understand how users move through your funnel, from product page to checkout, and identify drop-off stages where testing can generate the biggest impact.

Together, these analytics capabilities transform A/B testing from isolated experiments into a full-funnel growth system. You’re not just choosing winners, you’re building a continuous optimization engine based on real Shopify data.
4. Full Experiment Control
Take full control of your A/B test setup with flexible configuration options:
-
Set goals: Choose the primary metric that matters most to you, such as conversion rate or revenue. All other metrics will still be tracked and available in GemX Analytics.
-
Define traffic split: Easily distribute traffic between test variants (e.g., 50/50 or 70/30).
-
Target by device type: Run tests specifically on desktop, mobile, or both.
-
Target by visitor type: Segment your audience by new vs. returning visitors to refine test accuracy.
-
Target by traffic source: Focus your experiment on specific sources (e.g., Facebook Ads, email campaign, or organic traffic).
With these options, you can fine-tune your experiments to align with your experiment goals and audience behavior, ensuring more accurate and actionable results.
5. No-Code Setup
You don’t need to write a single line of code.
GemX is designed for marketers, store owners, and e-commerce teams who want to run experiments easily, without waiting for developer time.
