How CrazyBulk Lifted Conversion 141% and Delivered 16x ROI With a Guided Selling Quiz

CrazyBulk offers supplements for a wide range of fitness goals, but that variety created a familiar ecommerce problem: shoppers could see plenty of options without knowing which one fit their needs. When uncertainty became a barrier to purchase, the brand needed to replace browsing friction with clear guidance.

‍

The Challenge: Too Many Choices Were Stalling Purchase Decisions

Shoppers were leaving CrazyBulk without buying because they were unsure which supplements aligned with their goals. The brand’s conversion rate was around 2%, while the team was also watching the relationship between lifetime value and acquisition cost.

The opportunity was not simply to promote products more aggressively. CrazyBulk needed an experience that could ask the right questions, translate answers into useful recommendations, and make a large catalog feel easier to navigate.

The Approach: Give Every Shopper a Personalized Starting Point

CrazyBulk partnered with Digioh to build an interactive product recommendation quiz that acts like a digital guide, asking about fitness goals, dietary preferences, and workout habits before recommending relevant products.

• ‍Turn goals into product recommendations. The quiz uses shopper inputs to narrow the catalog and remove the guesswork that had been slowing purchase decisions.
• ‍Capture email while intent is high. Quiz engagement became a lead acquisition engine, adding more than 10,500 subscribers to Klaviyo.‍
• Send zero-party data into retention marketing. Goals and preferences captured in the quiz can be used for more relevant email and SMS segmentation.‍
• Extend the experience into mobile. CrazyBulk also runs the quiz inside its Tapcart-powered app so guided selling and data capture continue beyond the website.

CrazyBulk uses Digioh across both its Shopify storefront and Tapcart mobile app. Quiz responses and subscriber data flow into Klaviyo, giving the team a common source of customer preference data that can support more targeted retention campaigns.

The mobile integration expands the same guided selling and data strategy into a channel where CrazyBulk can continue engaging repeat shoppers.

“Our integration gives ecommerce teams the ability to showcase engaging, interactive product recommendation quizzes directly in their mobile apps.”

The Results: 7% Quiz Conversion, 16% Higher AOV, and 16x ROI

Quiz takers converted at 7% compared with CrazyBulk’s 2.9% overall conversion rate, a 141% increase. Those shoppers also generated a 16% higher average order value than non-quiz takers.

In 2024, quiz users contributed 7% of total online revenue, while the program generated a 16x ROI. The quiz also added more than 10,500 new email subscribers, expanding the audience available for lifecycle marketing.

Because zero-party data is passed into Klaviyo in real time, the value of the experience continues after the initial recommendation. CrazyBulk can segment customers around goals and preferences and use that context to support retention.

Why It Worked: The Quiz Converted Complexity Into Confidence

• ‍The recommendation logic mapped directly to shopper goals. Questions about desired outcomes, diet, and workouts made the experience feel useful rather than promotional.‍
• The quiz improved both conversion and order value. Better matching helped more visitors buy and helped quiz takers choose higher-value baskets.‍
• Data collection was built into the shopping experience. Email capture and zero-party data came from a high-intent interaction instead of a disconnected form.‍
• The experience followed shoppers across channels. Tapcart integration allowed CrazyBulk to use the same guided selling concept inside its mobile app.

Key Takeaways for Ecommerce Marketers

• ‍Use guided selling when assortment size creates friction. A large catalog can benefit from narrowing logic that turns broad choice into a manageable decision.‍
• Connect quiz questions to retention segments. The best inputs are useful both for the immediate recommendation and for future messaging.‍
• Measure revenue contribution, not only quiz engagement. Conversion rate, AOV, total revenue share, and ROI make the business impact easier to evaluate.‍
• Bring guided selling into the channels customers already use. A mobile-app quiz can extend the value of the onsite experience and create more data-rich touchpoints.
