A well-established German sportswear brand was experiencing steady traffic on their Shopify store—but conversions had plateaued. Pages were slow to load, and bounce rates were unusually high during promotional campaigns.
They turned to Code Elevator to optimize their Shopify store’s performance, improve mobile UX, and prepare their e-commerce experience for peak seasons like Black Friday and the holiday rush.
