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 Can You 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 Experiment
Test different versions of a single page. For example:
- Try two versions of a product page, one with a video, one with a static image
- Compare a minimalist landing page vs. one with social proof elements
- Test different call-to-action buttons or product descriptions
2. Multipage Testing Experiment
Test changes across several pages in a single experiment. Use multipage testing to:
- Run experiments across your homepage, collection pages, and product pages
- Create end-to-end funnel tests that measure performance across the customer journey
- Identify where drop-offs happen and fix friction points
3. Analytics
GemX Analytics gives you a clear view of how each page drives traffic, engagement, and sales — with side-by-side comparisons over time.
Track key metrics, spot trends, and understand how visitors interact with your content to optimize performance and make smarter decisions.
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, revenue, or bounce rate. 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 ecommerce teams who want to run experiments easily, without waiting for developer time.
