Scaling a multi-marketplace brand with PPC automation
A low-price, high-competition brand selling across a dozen Amazon marketplaces needed to scale without sacrificing margin. Seller AURA built a per-SKU bidding-stack automation strategy that grew sales while holding a lean Real ACoS.
The account
This is a business of low prices and fierce competition, where every point of ACoS matters. Growing it efficiently across multiple marketplaces meant solving manual effort, imprecise bidding and the tension between scale and margin.
Seller AURA automated the repetitive parts of PPC management, so operators could focus on strategy.
What was holding growth back
High manual effort
Managing PPC by hand across a large catalogue took enormous operator time.
Many marketplaces at once
Multiple marketplaces had to be monitored and advertised in simultaneously.
Suboptimal bid adjustments
Reactive, imprecise bidding led to inefficient spend.
Scale versus margin
Scaling risked compromising Real ACoS and gross margin.
How Seller AURA approached it
Per-SKU bidding stacks
A planned bidding stack for each SKU's campaigns in each marketplace, with high-barrier stacks on SKAG campaigns.
Rolling performance windows
Target bids adjusted on a rolling 30 to 90-day performance window.
Automated keyword import
Rules continuously imported new keywords per SKU using a custom ad-group strategy.
Account-wide propagation
A shared stack meant an improvement to one SKU applied across the whole account at once.

- Monthly sales rose from £21,830.18 in July 2025 to £63,063.46 in June 2026.
