"With hundreds of products, we struggled to surface the right pieces at the right time. Cluster not only solved that problem but shipped tests faster than I thought possible; we saw results in weeks, not months."

Introduction

Venderby's is a Danish fashion brand specializing in elevated wardrobe essentials with a minimalist aesthetic. They were growing fast in the European market and struggled to enable seamless product discovery with their sizable product catalog. They also wanted to tailor the shopping experience to the individual. They partnered with Cluster to systematically test improvements across their site, resulting in a 13.57% revenue per visitor increase and meaningful lifts in AOV and checkout completion.

The Solution

Cluster's analysis agent audited Venderby's entire customer journey and identified key friction points where shoppers were dropping off. Rather than attempting a full site redesign, the teams focused on targeted, data-driven experiments that could be executed quickly. Venderby's and Cluster ran a series of tests through the platform, prioritizing changes that maintained the brand's aesthetic while improving commercial performance.

Spotlight High Impact Tests for Venderby's

1. "Complete the Look" Upsell Module

One of the biggest advantages of shopping in a physical store is having a stylist suggest complementary pieces. Online shoppers at Venderby's were viewing products in isolation, missing out on outfit inspiration and additional purchase opportunities.

Cluster added a "Complete the Look" module directly below the product description on each PDP. The section displayed other items the model was wearing in the hero image, with streamlined add-to-cart buttons for effortless multi-item purchasing.

After

Result:

  • +10.96% Conversion Rate

  • +2.35% Average Order Value

2. Personalized Reviews in Cart

Social proof is critical, but different product categories have different objections—fit concerns for pants, fabric sensitivity for knitwear, and style confidence for everything else.

Cluster implemented dynamic reviews in the cart that changed based on what category the customer had added.

Category-Matched Reviews:

Pants — "Accurate to pictures… very lovely designs."

Wool — "Love the feel of the knitted pieces… usually have skin reactions to knitwear… Shipping was efficient."

Tops — "Obsessed with every piece… makes me feel so confident and stylish."


Result:

+8.03% Checkout Initiation Rate

+6.54% Revenue per Visitor
