Why We Built GemX

Traffic doesn’t always equal success. Businesses invest heavily in getting visitors to their sites, but when those clicks don’t convert into sales, the frustration mounts.

For many online merchants, low conversion rates are a major pain point, one that can make or break their business. The reality: clicks don’t pay the bills, but revenue does

And in an increasingly competitive landscape, businesses need more than just traffic. They need the real results.

As conversion rate optimization (CRO) grew from a buzzword to an essential strategy, merchants began experimenting with everything from copywriting tweaks to new upselling tactics.

But one crucial question remained: "How can you know if these changes are actually working?".

The answer is simple: A/B testing.

At GemPages, we’ve helped countless merchants design high-converting landing pages, and the feedback was clear—our users needed a tool that could go beyond design. 

They wanted to know which changes were driving conversions and which weren’t. We heard this request over and over: "Can you help us test what works?".

This was the spark that led to the creation of GemX.

GemX wasn’t just born out of market trends. It was a direct response to our users’ needs. We recognized that guesswork was no longer enough. 

Our merchants needed actionable insights that could transform their online strategies. So, we built GemX to give them exactly that. With the ability to test different versions of their pages, adjust designs, and measure performance with precision, GemX offers a smart, affordable solution to conversion challenges.

Clicks may bring visitors, but it’s conversions that drive success. With GemX, our users don’t just hope their changes work, they know.

As clicks don’t pay the bills, we built GemX.

How to Use GemX to Run Smarter Tests

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 Experiment

Template Testing allows you to compare two versions of the same page, your original (Control) and a new one (Variant), to identify which version performs better.

It helps users optimize their website's performance by running experiments that test different variations of web pages, enhancing the user experience and boosting conversion rates. Consequently, it increases opportunities for conversions and drives revenue growth.

Multipage Testing Experiment

GemX Multipage Testing is an advanced testing feature designed to help you make smarter design decisions not just on one page, but across your entire customer journey.

Instead of testing a single landing page or product page, this feature lets you test two complete sets of templates at once:

  • Group A (Control Group): Your current live designs.

  • Group B (Variant Group): A new version you want to test.

When a visitor lands on your store, they’re automatically assigned to either Group A or Group B, and will stay within that group for the entire session. 

At the end of the experiment, you'll receive both aggregated performance data by group and detailed comparisons between each matching template pair, so you can confidently determine which version performs better and apply it to your live store.

What Can You Test with GemX?

A/B testing works best when you focus on high-impact elements that directly influence how customers interact with your store. With GemX, Shopify merchants can experiment with multiple components across their storefront to identify what truly drives conversions.

Here are some of the most common elements you can test with GemX:

Hero Sections

The hero section is usually the first thing visitors see, which makes it a critical area for experimentation.

Possible tests include:

  • Different headline messaging

  • Alternative product images or lifestyle visuals

  • Background videos vs. static images

  • Different CTA placements within the hero section

Testing variations here helps identify which first impression resonates most with your audience.

Product Descriptions

Product descriptions influence how customers perceive value and trust the product.

You can experiment with:

  • Short vs. long descriptions

  • Bullet-point highlights vs. paragraph formats

  • Emotional storytelling vs. technical specifications

  • Feature-focused vs. benefit-focused copy

Even small copy changes can significantly improve conversion rates and engagement.

Pricing Displays

Pricing presentation can affect purchase decisions more than the price itself.

Common pricing tests include:

  • Showing discounts vs. regular pricing

  • Anchored pricing (e.g., Was $79 → Now $49)

  • Displaying bundle savings

  • Showing installment or payment options

These experiments help identify which pricing strategy encourages customers to purchase faster.

Testimonials and Reviews

Social proof plays a major role in building trust for new visitors.

With GemX, you can test:

  • Review placement (top vs. bottom of page)

  • Customer testimonials vs. star ratings

  • Number of reviews displayed

  • Highlighted customer quotes

For example, placing reviews closer to the product title may increase buyer confidence and improve conversions.

Page Layouts

The structure of a page can impact how easily customers find the information they need.

You can test layout changes such as:

  • Product image placement

  • Order of content sections

  • Mobile-first layout adjustments

  • Collapsible vs. expanded product details

Layout testing helps identify the structure that guides visitors smoothly toward checkout.

Multi-Page Funnel Elements

With Multipage Testing, you can also experiment across the entire customer journey instead of just a single page.

multipage funnel testing

Examples include testing:

  • Product page → Cart flow

  • Landing page → Product page sequence

  • Upsell pages in a sales funnel

  • Checkout messaging across multiple steps

Testing these flows helps merchants understand how each step of the funnel contributes to final conversions.
