Case Study: How BrillMark’s Expertise Skyrocketed Toplids’ Conversions by 128%
In the competitive eCommerce landscape, an outdated website makes the business bleed – it’s a barrier to growth. Toplids, a provider of premium aquarium accessories, faced this challenge. Their existing Shopify store struggled with confusing navigation, limited product customization, and suboptimal performance, hindering their ability to convert visitors into customers.
Recognising the need for a significant overhaul, Toplids partnered with BrillMark, a full-service experimentation agency, to migrate, redesign, and optimize their online store. Acting as expert experimentation consultants, BrillMark’s goal was ambitious: execute a conversion-focused redesign, implement robust customization features, and dramatically improve conversion rates ahead of the crucial Black Friday period. The results? A staggering 128% increase in conversion rate within just three months post-launch and optimisation.
