E-Commerce Executive and Digital Marketing Specialist - Kates Associated Industries Limited
Sep 2023 - Present • 2 yrs 10 mos
Kates Associated Industries Limited operated an Official Store on Jumia with an established portfolio of beauty and personal care products. Despite having recognizable brands, the company had limited digital visibility, stagnant sales, low customer engagement, and minimal marketplace traction. The objective was simple: increase online sales. By combining marketplace SEO, Jumia Sponsored Ads, product optimization, pricing strategy, inventory management, customer review generation, and seasonal campaign execution, I transformed the store from fewer than 20 monthly orders to an average of 1,000+ monthly orders while achieving a ROAS of 5.29.
