Coupang invests heavily in data-driven digital advertising across Naver, Kakao, and Google Korea, using closed-loop attribution from its owned e-commerce environment to measure ROI at a granularity unavailable to competitors using third-party ad platforms.
The WOW membership program is the primary customer retention and monetization vehicle. Marketing investment is directed toward converting existing non-member active customers to paid membership, as WOW members generate significantly higher lifetime value.
