Our Shopify CRO at a glance
Who we work with
Mid-market and enterprise Shopify and Shopify Plus DTC brands, typically generating $2M+ in annual revenue, processing 1,000+ orders per month, and investing $10K+ per month in paid media. Some of our clients include Enhance Auto, Mi Amante, Shelly, Moon Nude, and Takomo Golf.
What we manage
The full CRO program in house, including research, strategy, A/B testing, UX improvements, development, QA, site speed, tracking, and implementation of winning tests.
How we research
Our process is supported by Signalveritas, craftberry’s proprietary CRO research tool, which helps analyse customer feedback and surface stronger testing hypotheses.
How we measure success
Revenue per visitor and profit per visitor are measured alongside conversion rate and year-over-year revenue growth. This ensures that higher conversion translates into meaningful commercial growth.
What results we target
We aim to generate at least a 4x return on the CRO retainer, with some clients achieving up to 20x. The program is backed by a minimum ROI guarantee based on the amount invested with craftberry within 6 months.
Technology we use
Signalveritas, our proprietary CRO research tool, alongside Intelligems, our A/B testing partner, GA4, Shopify analytics, heatmaps, session recordings, and Shopify Plus.

Measured from your first test
We sell CRO based on the outcome it produces. Our aim is to deliver at least four times your investment in added revenue, and we guarantee a minimum lift. If we have not delivered at least a 10% improvement in revenue per visitor 90 days after the first test, as measured in the CRO tools, we continue working at no additional cost until we do. We set the exact target for each client based on your traffic and revenue.

Every result below comes from a controlled A/B test run on the client's own traffic.
Enhance Auto
AutomotiveWe found that trusted-creator YouTube reviews were buried at the bottom of the page, so shoppers made their decision before seeing the proof. We moved the reviews directly below the hero and refreshed the thumbnails to feature the creators' faces. Across their 2026 CRO program, 75% of the tests we have concluded have won.
Mi Amante
BeautyThe product-page upsells lacked a clear hierarchy, so shoppers could not easily distinguish between a single item, a bundle, and the better-value tier. We rebuilt the upsell as a single-select quantity ladder with per-unit pricing, struck-through original prices, savings, and "Most Popular" and "Best Value" badges. Overall, 80% of their concluded tests have won.
Shelly
ElectronicsThe device was sold individually, as a 2-pack, and as a 4-pack, but nothing guided shoppers towards the larger quantities. We added a "Most Popular" label to the 2-pack and a "Best Value" label to the 4-pack, without changing the price or layout. Framing changed the purchase decision without changing the price.
Moon Nude
Fashion accessoriesWe run a continuous testing program across the cart, product page, and homepage. Eight of the tests we have run for the brand have won so far this year.

Read the reviewOur CRO strategy on Shopify
We usually begin CRO once a store has meaningful post-launch data, roughly 1.5 to 2 months after a launch or migration.
Testing before that means testing against noise.
Reliable A/B testing generally requires around 1,000 orders per month. Below that threshold, we focus on qualitative research and roll out changes directly instead of splitting traffic.
1. We fix the data before testing anything.
If tracking is inaccurate, no test can produce a trustworthy result.
Before running a single experiment, we validate analytics and attribution so the numbers behind your decisions are accurate.
2. We identify where the journey breaks down.
We combine GA4 and Shopify Analytics with manual mobile and desktop walkthroughs to pinpoint where shoppers leave the funnel and what disrupts their customer experience.
3. We uncover why customers hesitate.
Reviews, support chats, and post-purchase surveys reveal the questions, objections, and product benefits that store pages often miss.
Our AI research tool, Signalveritas, accelerates this process and helps surface higher-quality hypotheses faster.
4. We prioritise with a scoring framework.
We score every hypothesis based on potential, importance, and ease, so the tests with the greatest upside and lowest effort run first.
This keeps the biggest blockers ahead of smaller refinements.
5. We build and QA the variant in house.
The CRO expert writes the requirements, our UX designer creates the mockup, our developer implements it, and QA checks it before it goes live.
One team, no external handoffs.
6. We run each test to significance across real business cycles.
We aim for 95% statistical significance and run each test for at least two full business cycles, because a Monday visitor behaves differently from a Friday visitor. We stop losing tests early and allow winners to compound.
7. We analyse the results, implement the winners, and learn.
Every outcome, whether a win or a loss, enters a knowledge base that makes the next hypothesis stronger.
We run CRO as an ongoing operation in which each month builds on the last.
What our Shopify CRO service covers
In our experience, CRO covers the entire journey from landing page to checkout, along with the technical foundation underneath it.
Conversion research and diagnostics.
Usability audits, session recordings, heatmaps, surveys, and analysis of your GA4 and Shopify data. This is how we identify where revenue leaks and why before changing anything.
Product-page and buy-box optimization.
Clear option hierarchy, honest value framing, objection handling, and upsell structure. This is where many of our biggest wins come from because it is usually where shoppers stall.
Cart, checkout, and AOV.
Bundling, quantity ladders, cross-sells, and free-shipping thresholds. In the carts we optimise, the second item from a customer you have already won is often the most cost-efficient revenue in the store.
Collections, navigation, and filtering.
For large cataloges, we treat the filter system as a primary conversion lever because fewer clicks to the right product can win the sale.
Site speed and Core Web Vitals.
In the stores we audit, app scripts are usually the main culprit. Faster pages improve both conversion and repeat purchase, and we often replace stacked apps with a single custom build to reduce script weight and recurring fees at the same time.
Tracking and attribution.
Server-side tracking and a clean GA4 setup, so every test result we report is one you can trust.
We focus on the metrics that move revenue: conversion rate, average order value, revenue per visitor, cart abandonment, and checkout completion.
