Case Study: Ice Jewellery achieves 52% conversion lift and 19% AOV growth with BigCommerce

New Platform Helps Ice Jewellery Turn Up the Heat to Melt the Hearts of Its Customers

Ice Jewellery is a family-run online jewellery retailer founded by brothers Simon and Nick Molnar that outgrew its legacy Magento setup. The old site suffered from poor performance, checkout and payment issues, an inflexible structure that required manual product ranking across 20,000+ SKUs, and SEO and mobile limitations — all of which suppressed conversion rates and led to lost sales.

Migrating to BigCommerce with agency Moustache Republic delivered the flexibility, automated merchandising and SEO-friendly structure they needed, plus personalization and search integrations. Results included a 52% increase in conversion rate, a 19% rise in average order value, a 563% single-day YoY conversion uplift, and 10% more revenue even after cutting marketing spend by 60%.
