The Challenge

A leading e-commerce brand was facing stagnating online sales and low customer retention rates, struggling to compete in a crowded market. Despite steady traffic, conversion rates had plateaued, repeat purchase rates dropped below industry benchmarks, and ad performance deteriorated due to rising CPMs. The brand lacked a unified user experience and personalized retention engine, causing high cart abandonment and low lifetime value.

The Solution

I developed a comprehensive digital marketing strategy focused on improving user experience, optimizing conversion funnels, and implementing targeted advertising campaigns. Key initiatives: UX audit & CRO (checkout flow, site speed), AI-driven product recommendations, segmented email/SMS retention flows, and omnichannel ad strategy (Meta, Google, TikTok) using first-party data & lookalike modeling. Also launched a loyalty program and post-purchase engagement automation.
