Case Study: Major International Brand achieves 30% reduction in Amazon ad overspending with Rithum

Major International Brand Curbs Overspending on Amazon Advertising by 30%

An established global consumer brand with nearly a century in business faced runaway Amazon advertising costs and poor visibility because campaigns were fragmented across multiple accounts and departments. Without centralized reporting, clear goals, advanced keyword tactics or strict ACoS targets, the company was overspending at scale and needed a faster, more cost‑effective approach.

ChannelAdvisor Managed Services audited and rebuilt the company’s Amazon strategy, consolidated accounts, optimized keywords and bidding (including negative keywords), and introduced centralized pacing and reporting. Within a month ad costs fell 30%; after a year the ad budget was within 1% of target, ACoS improved 20%, ad revenue grew 24% year‑over‑year, and weekly sales increased substantially.
