Discovering Rebuy
Nermin has been working in conversion rate optimisation (CRO) consulting for over a decade, supporting brands across a wide range of eCommerce platforms and solutions. When Nermin joined Blend Commerce last year and shifted her focus entirely to Shopify brands, one of the most exciting discoveries was getting hands-on with Rebuy.
Thanks to Rebuy, projects that used to take weeks or even months on custom-coded websites can now be launched within minutes on a Shopify store. What makes this even more powerful is that it doesn’t require advanced technical or development skills. A marketer or product team manager can easily implement high-impact changes without relying heavily on engineering resources.
To give you an example: one of the largest European brands Nermin had previously consulted for, operating across 61 countries, invested nearly six months into developing its internal search algorithm. The process required dozens of meetings, significant financial investment, and careful coordination between multiple stakeholders and teams.
Yet, the very features they aimed for could have been launched using Rebuy Smart Search within a few hours. Honestly, there are times when Nermin wants to suggest a Shopify migration to brands just so they can benefit from Rebuy.
Why Rebuy Stands Out
For Shopify merchants, Rebuy combines features that would typically require multiple apps into one unified solution, saving time, money, and maintenance effort.
With Rebuy, brands can:
- Customise your cart drawer with Rebuy Smart Cart
- Deploy personalised product recommendation modules across your site,
- Create and test bundles
- Enhance user experience with Smart Search
- Customise the checkout within Shopify’s constraints
- Build more effective post-purchase and landing page flows
- And, most importantly, continuously test everything while integrating seamlessly with other tools.
In the past, Nermin has worked with Shopify clients who used different platforms for these features. The problem was that it made things more complicated for teams to learn, added extra work to manage, and slowed down their stores with too many apps, hurting conversion rates.
Rebuy’s true game-changing power lies in its accessibility. Even with limited technical knowledge, teams can implement and optimise all of these features with ease.
Case Study #1: Increasing Conversion with Rebuy's Recently Viewed Product Module
The Problem
Analytics revealed a key imbalance in our store performance: while only 24% of site visits came from returning visitors, they accounted for 46% of total revenue. Even more striking, their conversion rate was 176% higher than that of new visitors.
This suggested a behaviour pattern: many users were not purchasing during their first session but instead returning later, after further research, to complete their order. The challenge was clear: how could we make it easier for both new and returning visitors to quickly find and purchase the products they had already shown interest in?
New vs Returning Customers
The Hypothesis
If we added a Recently Viewed Product Recommendation Module to the homepage, we expected:
- Returning visitors would have an easier path to purchase, increasing their likelihood of conversion.
- New visitors exploring multiple product pages would also benefit, as they could quickly revisit items they had browsed, without needing to search again.
The Solution
Using Rebuy, we created the necessary data source and integrated it with Convert, our A/B testing platform. This allowed us to run a controlled test comparing two variations: one with the Recently Viewed carousel added to the homepage, and one without.
Varied Rebuy Product Recommendation Modules
The Results
The impact was dramatic. The homepage with the Recently Viewed module outperformed the control in every key metric:
- Conversion Rate: +44.31%
- Average Order Value (AOV): +191.8%
-
Revenue per Visitor: +206.06%
Recently Viewed Product Convert Data
Based on these results, we permanently implemented the Recently Viewed Product module on the homepage through Rebuy.
This test highlights the importance of surfacing personalised, context-aware recommendations, especially for users who may need multiple touchpoints before purchasing.
It also underscores one of Rebuy’s most substantial advantages: flexibility. Beyond its own native A/B testing tools, Rebuy can integrate seamlessly with platforms like Convert and Intelligems, enabling teams to validate ideas quickly and continuously optimise the customer journey.
This forms part of the structured testing approach within our CRO Program, designed to combine advanced tooling with customer lifetime value insights.
Case Study #2: Increasing Revenue per Visitor with a Rebuy Smart Cart
The Problem
According to Shopify Analytics, our brand’s average order quantity per order was 2.63. While reviewing session recordings, we noticed a recurring behaviour: users frequently added multiple items to their cart but removed some before completing checkout.
This insight led us to a key assumption: constantly showing the full Cart Drawer experience might overwhelm users. Because it covers the entire screen every time, it could disrupt the flow and potentially reduce Average Order Value (AOV).
The Hypothesis
Instead of pushing users straight into the purchase process, we believed a more balanced experience would help. By combining the existing mini notification cart pop-up with Rebuy Smart Cart functionality, users could stay engaged in shopping without feeling pressured, while still having easy access to all Rebuy Smart Cart features when they needed them.
The Solution
We transitioned from the brand’s standard cart drawer to the Rebuy Smart Cart structure. Thanks to Rebuy’s flexibility, we could configure it so that the Smart Cart opens via the notification, rather than displaying immediately.
Original, Variant 1 and Variant 2 with Rebuy Smart Cart A/B/C Test
Based on the experiment outcomes, Variant 2 (Notification → Smart Cart) delivered clear improvements compared to the original mini notification cart:
- eCommerce Conversion Rate: +2.49%
- Average Order Value (AOV): +1.31%
- Revenue per Visitor (RPV): +7.83%
- Average Purchase Revenue per User: +2.88%
Variant 2 Metrics Achieved
The Results
These results confirmed our assumption: by gradually easing users into the new Rebuy Smart Cart experience, rather than displaying it right away, we reduced friction and encouraged higher-value purchases.
The flexibility of Rebuy's Smart Cart truly drove the success of this A/B test. Its fully customisable structure allowed us to create a shopping experience precisely tailored to our users’ needs.
Customised cart experiences are a common area of focus in our CRO Insights service, where we identify and prioritise opportunities to increase AOV and Revenue.
Case Study #3: Rebuy's A/B Testing Tool
The Problem
During user testing, we noticed a recurring issue inside the Rebuy Smart Cart: users sometimes confused the product recommendations (upsell/cross-sell items) with the products they had already added to their cart. This lack of clear separation risked creating friction and reducing the effectiveness of upsell opportunities.
The Hypothesis
We assumed that two design adjustments could solve this problem:
Variant 1: Visual distinction
Changing the background styling of the recommendation area to create a clearer separation from cart items.
Variant 2: Carousel Format
Displaying upsell/cross-sell products within a carousel at the bottom of the Smart Cart, making the experience feel more organised and less cluttered.
Variant 1 vs Variant 2 with Rebuy A/B Testing
The Solution
We implemented this test for our client using Rebuy’s A/B testing feature. This means that future A/B tests with Rebuy can be run directly, without needing an external platform, while measuring their direct impact on revenue metrics.
We tested two different variants with Rebuy over a two-week period.
The Results
Based on the experiment outcomes, displaying Rebuy Smart Cart upsell and cross-sell items in a carousel (Variant 2) outperformed the original version:
- Variant 1 (Background styling only):
–7% decrease in Revenue per Visitor
- Variant 2 (Carousel layout):
+12.5% increase in Revenue per Visitor
Rebuy A/B Test Data
Simply changing background styling was not effective and even had a negative impact on performance.
Moving upsell/cross-sell items into a dedicated carousel created a clearer user experience and drove a +12.5% lift in Revenue per Visitor.
The test demonstrates the importance of not only adding upsell opportunities but also presenting them in a way that feels intuitive and distinct from the shopping cart itself.
One of the biggest advantages of this test was leveraging Rebuy’s built-in A/B testing feature. This feature not only simplified the development process and reduced costs but also made experimentation accessible. For smaller businesses that may not have the resources to invest in standalone A/B testing platforms, this functionality removes a major barrier and makes continuous optimisation achievable.
These are just a few of the experiments we’ve run with Rebuy. For more examples across different Shopify brands, head to our A/B Test Case Studies.
What These Tests Tell Us
The three experiments highlight a consistent truth: technology is only as effective as the strategy behind it. Rebuy provides the flexibility and speed to launch high-impact features, but the real gains come from applying CRO expertise to shape, test, and validate those ideas.
At Blend, this is where our strategists excel. By combining deep CRO knowledge with tools like Rebuy, we help Shopify brands turn incremental changes into measurable growth, not just in conversion rate and AOV, but in overall customer experience and lifetime value.
