Case Study: Lights4fun increases revenue 22% and transactions 10% with Klevu AI Personalization

Lights4Fun - Customer Case Study

Lights4fun, a UK-based homewares retailer that scaled from a family business to an international operation, faced stagnating growth tied to its legacy tech stack after moving to Shopify. To improve onsite search and personalization, Lights4fun integrated Klevu, using Klevu’s Search Personalization Engine and Smart Search tools as part of its Shopify tech stack.

Klevu implemented one-to-one search personalization and Smart Recommendations (tested via an A/B split from March 2020–May 2021), resulting in measurable uplifts: +10% transactions, +0.3% conversion rate, +22% revenue and +10% per-session value. Klevu’s fuss-free Shopify integration and automated personalization also freed Lights4fun to focus on content and CRO while delivering higher customer spend and expanded market growth.
