Case Study: Nuobell Achieves $1.36M in Amazon Sales with SellerApp

How a Swedish fitness brand scaled to $1,364,325 in sales within months of joining SellerApp

Nuobell, a Swedish fitness brand selling adjustable dumbbells on Amazon US, struggled early on with reseller crowding, weak A+ content, no reviews, inconsistent sales, and manual ad management that drove ACoS as high as 42–48%. As a new Amazon presence with little data or brand trust, the company needed a way to differentiate its products and stabilize growth.

SellerApp stepped in with full-funnel PPC, AI bid and budget automation, search term and negative keyword optimization, listing and A+ content improvements, keyword tracking, and custom dashboards. With SellerApp, Nuobell scaled to $1.36M in sales, increased ad revenue to $892,271, lifted total sales from $35,385 to $1,364,325, cut ACoS to 11.15%, reduced TACoS to 7.36%, and improved conversion rate from 0.55% to 1.93%.
