How LN Digital Grew Ad Purchases 127% in 30 Days

LN Digital, a Brazil-based seller, began their Amazon PPC journey in 2023. The company first tested the U.S. marketplace before strategically pivoting to focus on Brazil. Today, LN Digital specializes in domestic utility products, with a strong presence in the water filter category.

The client first approached us with a concern that their Advertising Cost of Sales (ACOS) was alarmingly high and were determined to improve ad efficiency and unlock better campaign performance.

Despite their efforts, manual optimization was a time-consuming grind. Ad spend increased with lower returns. On top of that, the data felt overwhelming. They lacked clarity on how to access, interpret, or apply it in a way that could drive results.

In search of answers, the client enrolled in an external crash course on Amazon advertising. During the course, their mentor personally recommended SellerMate.AI as a trusted solution for Amazon PPC optimization and automation. That recommendation, shared casually over a messaging app, was the turning point.

SellerMate focused on delivering data-backed AI optimization that translated into measurable performance improvements. To ensure strategies were aligned with the client’s unique goals, the customer success team designed tailored automation rules based on the account’s historical performance.

Driving Performance with AI-Powered Automation and Smart Insights

Client implemented bid and budget dayparting rules to control ad spend and optimize budget allocation throughout the day. In addition, we built customized smart board dashboards that provided clear weekly and monthly visibility into results, making it easy to track progress and compare pre- vs post-optimization performance.

Together, these solutions created a streamlined, performance-driven advertising strategy that gave the client greater confidence and control over their campaigns.

Within just 30 days, the account achieved significant improvements across key advertising metrics. Shopper engagement rose sharply, with CTR increasing by 17.5% and CVR nearly doubling (+98%). This translated into a 127% jump in ad-driven purchases and a 48.6% uplift in ad sales, directly boosting revenue. Importantly, these gains came alongside improved efficiency. ACoS dropped by 5%, while ROAS climbed by 5.3%, proving that growth was balanced with profitability.

Following the 30-day optimization success, SellerMate helped LN Digital implement more rule-based automations to maintain spend control while continuing to drive sales.
