Case Study: Castorama achieves 24% higher search conversions with Nosto

Castorama Conversions Grow By 24% From Site Search

Castorama, Poland’s largest home improvement retailer, needed to fix poor site search relevance, reduce manual work, and better support omnichannel shopping across online and offline channels. The company turned to Nosto’s site search solution, SearchNode, to improve results for its large e-commerce catalog and handle Polish language nuances more effectively.

Nosto implemented an AI-powered, automated search and merchandising setup with custom algorithms, contextual filters, smarter autocomplete, and faster search experiences. The solution launched in seven weeks and quickly delivered measurable gains: conversion rates from sessions with search rose by 24%, CTR from site search increased by 30%, and during the pandemic site-search sessions drove +186% YOY conversion growth and +211% YOY revenue growth.
