SEEK is a multidisciplinary team blending strategy, design, and technology to deliver human-centered digital products, services, and experiences that generate real business value. We are expanding our analytics capability to support data-driven decisions across multiple storefronts (US, UK, FR) in a headless Magento + Next.js environment. This project focuses on implementing robust, accurate data tracking and analytics across all store views, ensuring data integrity for ecommerce operations, marketing attribution, and conversion optimization. The engagement involves collaborating with our development and marketing teams to deploy GA4 and GTM across dev, staging, and production, configure data layers, and establish reliable cross-domain tracking and consent-compliant measurement flows. The result will be a scalable analytics foundation that empowers reliable reporting, experimentation, and strategic insights post go-live.
