Most Shopify stores struggle to run A/B tests consistently because setup feels complicated, the process takes too much time, and teams often don’t know which idea deserves to be tested first. Decisions usually end up based on gut feeling rather than validated signals.
GemX reframes A/B testing into something directly tied to business outcomes instead of theory. Every experiment is designed to validate what actually moves revenue inside your funnel. A faster testing cycle unlocks clearer insights sooner, reduces wasted energy, and helps teams scale growth with confidence.
Overview of A/B Testing in Shopify
What is Shopify A/B Testing?
A/B testing in Shopify means comparing two versions of the same page or experience to see which one drives better performance based on real shopper behavior. Instead of guessing which headline, layout, offer, or content angle “should” convert better, merchants get clarity through data. Every change is validated through audience interaction, not through assumption or subjective preference.
Why A/B Testing is Critical for Shopify Growth?
Rising costs for Meta ads and other paid channels make each visitor more valuable than ever, turning funnel optimization into a necessity rather than an option. Performance now matters more than visual aesthetics alone, and relying on guesswork can significantly slow growth. A/B testing provides the only reliable way to make decisions based on real data and actual customer behavior.
Key reasons A/B testing matters for Shopify merchants:
- Performance always trumps aesthetics when driving conversions
- Data-driven decisions replace subjective guesses
- Merchants who test consistently enjoy compounding conversion improvements over time
GemX – A/B Testing App Built for Shopify Growth
GemX is an A/B testing solution built specifically for Shopify merchants and growth teams who want to run experiments faster and smarter. Strategically, it helps teams validate ideas quickly, reduce reliance on assumptions, and improve overall funnel performance. From a feature perspective, GemX reduces developer dependency, simplifies experiment setup, and shortens the time it takes to turn insights into action.
How GemX Simplifies the A/B Testing Workflow?
Running A/B tests on Shopify can feel overwhelming, particularly for non-technical teams. Traditional testing often requires coding, manual duplication of pages, or a complex setup that slows down the ability to validate ideas.
GemX addresses these challenges by providing a streamlined, no-code environment designed to make experimentation fast, intuitive, and data-driven. Every step, from selecting a control page to launching a variant and tracking results, is designed to minimize friction and maximize actionable insights.
Core workflow benefits:
- No-code flow for fast setup without developer support, lowering technical barriers
- Variant creation is seamless when the control page is built with GemPages, enabling easy duplication and editing
- Template-driven tests simplify repetitive work and standardize experiment setup across multiple campaigns
- Full-funnel visibility, tracking performance across landing pages, product pages, and checkout flows, rather than focusing on isolated pages
- Real-time analytics and actionable results that directly inform business decisions and help prioritize future tests
Key Use Cases You Can Test With GemX
Merchants can apply GemX testing to nearly every critical touchpoint in their Shopify store. By experimenting with different variations, teams can uncover what truly drives conversions and revenue growth.
Examples of high-impact experiments:
- Landing page variations to improve click-through rates, engagement, and add-to-cart conversions
- Product page (PDP) layouts, media angles, and image arrangements to highlight product value
- Offer messaging, bundle deals, and price structure experiments to identify the most compelling propositions
- Placement and design of social proof, reviews, and trust elements to increase credibility and reduce hesitation
- CTA copy, design, size, and positioning adjustments to maximize clicks and conversions
This approach allows merchants to run structured, repeatable experiments, learn quickly from real customer behavior, and scale optimizations across the store without relying on guesswork or developer-heavy processes. Over time, these small, continuous improvements compound, producing measurable growth and stronger conversion performance.
How To Start Your First Test with GemX (Step-by-Step)
Starting your first A/B test in GemX can be straightforward when the workflow is clear. GemX allows you to create two types of experiments:
- Template Testing: focuses on optimizing individual pages.
- Multipage Testing: focuses on optimizing the entire sales funnel.
Template Testing in GemX lets you A/B test different templates (Control vs. Variant) to see which one performs better based on key metrics like conversion or revenue.
To create a template testing experiment in GemX, follow these steps:
Step 1: Access the GemX Dashboard
From your Shopify Admin, locate the GemX: CRO & A/B Testing under the Apps section. Click on Create new experiment.
Then, select Create Template Experiment.
Step 2: Select the control template
The Control is your original or default template. It serves as the baseline for comparison against the experimental version (Variant).
Step 3: Select the variant template
The Variant is the alternative version you’ll test against the Control. This could involve a different design, layout, or messaging approach.
There are two scenarios:
Scenario 1: If your Control is a Shopify template, you will have one option: Select template for variant, which allows you to choose an existing template as the Variant.
Scenario 2: If your Control is a GemPages template, you have two options for creating the Variant:
- Select an existing template: Choose another existing template to use as the Variant.
- Create Variant based on Control: Create a duplicate of the Control template as the Variant.
Important note: The option “Create Variant based on Control” is only available in GemPages version 7.
If you choose the “Create Variant based on Control” option, a new tab will open in the GemPages Editor where you can customize the duplicated template.
This duplicated template is used exclusively within GemX and will not appear in your GemPages page listing.
Important note: You can change, preview, and remove templates. However, removal is only allowed for the Variant template, not the Control.
Also, you can view the specific Pages/Products/Collections/Articles(*) to test within the Template pair in the campaign by clicking the Pages/Products/Collections/Articles to test button:
Step 4: Configure Advanced Settings
Then, configure the Advanced Settings before starting your experiment.
- Set winning metric
Choose the primary metric that’s most important to you for this test. It helps to identify which version wins.
- Set device type
You can choose to target specific device types, including desktop, tablet, or mobile or All devices. This ensures that the variant templates are shown only to visitors on the selected devices. The default is set to All devices.
- Set visitor type
All Visitors: This option includes both new and returning visitors, allowing you to test the templates across your entire audience.
New Visitors: Target only first-time visitors to your website. This is useful if you want to see how your templates perform with visitors who have no prior experience with your site.
Returning Visitors: Focus on visitors who have previously visited your website. This can help you understand how familiar visitors react to the changes in the template compared to their past experiences.
- Set traffic source
All Sources: Include all traffic sources in your A/B test. This option is ideal if you want to get a comprehensive view of how your templates perform across all channels.
Specific Source: Target traffic from specific channels to see how your templates perform with visitors coming from particular sources. The specific sources you can target include:
|
Referral |
Visitors who arrive at your site through links from other websites. |
|
Organic Social |
Traffic from unpaid social media posts or shares |
|
Organic Search |
Visitors who find your site through unpaid search engine results |
|
|
Traffic generated from email campaigns |
|
Paid Search |
Traffic from paid search engine ads |
|
SMS |
Visitors who access your site via links sent through SMS campaigns |
Important note: These traffic sources are currently fixed and cannot be customized. If you need additional options, feel free to send us a Feature Request.
- Set traffic split
You'll allocate the percentage of traffic that each variant will receive during the A/B test. This distribution determines how many visitors will see the origin template versus the variant template when they visit the associated page.
- Set Markets and Language
Show the page only to visitors coming from selected markets and languages.
Step 5: Activate your experiment
You'll activate your experiment, making it live and operational based on the settings you've configured.
Once you click the start button, your experiment will go live. The live page will start functioning according to the settings you've established, such as the selected templates, traffic allocation, targeted devices, visitor types, and traffic sources.

Best Practices for Winning Testing Velocity
The impact of A/B testing depends on running the right experiments at the right pace, rather than simply running tests. High-velocity testing helps merchants gain insights faster, reduce wasted effort, and steadily improve conversion performance across their Shopify store.
Key practices for faster, smarter testing:
- Focus on small but meaningful tests that can move key metrics instead of minor aesthetic tweaks
- Run one test per funnel stage at a time to avoid overlapping results and confusion
- Prioritize speed of iteration, as roughly 70% of testing value comes from learning quickly and iterating often
- Make decisions based on data rather than opinions or assumptions, letting results guide next steps
These practices build a continuous learning loop, allowing teams to gain insights faster and achieve steady, long-term conversion growth.

Frequently Asked Question
What is GemX A/B Testing?
GemX A/B Testing is a Shopify app that allows merchants to run experiments comparing different page or template variations to see which performs better. By duplicating a control page (ideally built with GemPages) into a variant, you can test layouts, messaging, offers, or CTAs, and track the data-driven results across key metrics such as conversion rate, revenue, and engagement.
How long should an A/B test run to get reliable results with GemX?
Reliable results typically require around two weeks of running an experiment or collecting approximately 2,000 visitors, depending on traffic and audience size. This timeframe ensures enough data for GemX to determine a statistically meaningful winner while still allowing teams to iterate quickly.
Which pages or funnel stages can I A/B test using GemX?
GemX supports testing across virtually every stage of a Shopify funnel. Merchants can run experiments on landing pages, product pages, collections, blog posts, and even multi-page flows, helping teams identify which changes drive the most conversions at each step of the customer journey.
Does running experiments with GemX impact my store's performance or page speed?
Experiments in GemX are designed to run smoothly without slowing down your Shopify store. The app works efficiently in the background, and Variant pages created for testing do not affect the performance of live pages outside the experiment. Merchants can run multiple tests while maintaining a fast, responsive storefront.
