“Many of our products come in dozens of colours, and those pages used to take forever to load. With Speed Kit it simply feels faster.”
— Steven Müller, Head of Marketing & Sales, VBS Hobby Service GmbH

Introduction

VBS Hobby has supplied craft and hobby materials since 1964 and is today one of Europe's largest specialist mail-order suppliers in its field, with 16,000 products and more than 750,000 regular customers. Its busiest months run from autumn to Christmas.

Challenge

Many products at VBS Hobby have dozens of variants. One acrylic paint alone is sold in around fifty shades of yellow, and its product page has to load all of them, which makes pages like this slow. An earlier front-end clean-up had fixed the worst problems, but the Core Web Vitals in Google Search Console were still poor. The nine country shops run on a licensed shop system without a CDN, and shop updates ship every six to eight weeks.

Solution

Speed Kit runs on top of the existing shop and required no change to its architecture. It works out which page a visitor is likely to open next and prepares it in the background, so that page is often already complete in the browser by the time the customer clicks.

Results

Business Impact — PoC Phase: During the PoC phase, half of the visitors got Speed Kit and the other half, the control group, did not. The Speed Kit group reached a 2.59% higher conversion rate, and add-to-cart rose by 2.89%.
