How WLS achieved +32% return with data, CRO, and smart tooling
WLS Products is the go-to brand for people who take a conscious approach to their health. Its carefully curated range includes supplements and protein products, often tailored to individuals who have undergone bariatric surgery. For years, WLS and XSARUS have worked together on e-commerce and online growth. The challenge we took on once again: how do you optimize the digital customer journey to drive more growth and conversions?
The challenge: a strong foundation with room for more
How do you turn visitors into customers? And how do you increase campaign impact without raising your budget? These questions marked the starting point of this project. WLS already had a solid foundation in place. At the same time, we identified clear opportunities together:
- Customer data and insights from user behavior were not fully leveraged
- Strong customer loyalty created opportunities to improve conversion
- Personalization within the customer journey remained limited
- Campaigns delivered insufficient return
The approach: smart building blocks for sustainable growth
Not a one-off project, but an ongoing trajectory focused on continuous optimization. Data and user insights form the foundation, translated into actions that deliver measurable results.
- CRO as a continuous optimization cycle
Using heatmaps, feedback tools, and A/B testing, we continuously gather insights from user behavior and improve the bottlenecks that emerge.
→ Result: a smoother customer journey and fewer drop-offs. - Webshop redesign
We gave the webshop a fresh new look, built on trust and ease of use.
→ Result: longer sessions, higher customer satisfaction, and increased conversion. - Aiden product advisor
We introduced Aiden, a smart product advisor that guides customers step by step to the right product.
→ Result: +160% conversion among new visitors who use Aiden. - Personalization and automation with Spotler Activate
We personalized the webshop and email flows with smart retargeting and relevant triggers.
→ Result: better timing, higher relevance, and more repeat purchases. - Driving margin with an improved performance advertising strategy
We optimized campaign structures and audience segmentation without increasing the budget.
→ Result: +32% higher ROI, achieved purely through smarter media buying.
These results are no coincidence. They stem from a strategy where data, creativity, and smart technology are perfectly aligned. Just as important is the collaboration itself, built on trust, speed, and a shared ambition for growth.
And the optimization continues. The 2026 roadmap includes expanding Aiden, further optimizing SEO and SEA, and introducing a subscription model for repeat purchases.
