Amazon role
Key marketplace for both B2B and B2C growth
“Capline completely transformed our performance. We had been struggling to scale before working with them, but within a few weeks Capline tripled our advertising profit and doubled our advertising revenue, all while maintaining a steady ROAS of 20x. This proves their unique ability to drive rapid, efficient growth. No other tool or agency has delivered such dramatic results, so quickly. Capline truly sets a new standard.”
The challenge
A Fortune 200 office supplies brand was growing quickly on Amazon, but its advertising program was both inefficient and incomplete. A meaningful share of their 50k+ product catalog lacked ad support and had very thin margins, while other products carried unprofitable spend that Finance could not easily see or explain. Existing partners focused on ROAS and coverage but did not integrate product-level cost, margin, and inventory data into their bidding logic, so large portions of the catalog were deemed un-advertisable.
What Capline did
Capline onboarded the brand's vast Amazon catalog in just three days and rebuilt the program around profit-first decisions.. Campaigns were restructured from multi-SKU, blended setups into a single-SKU architecture that enabled product-level bidding, keyword and product targeting expansion, and clear separation of branded vs. non-branded performance. Capline's machine-learning bidding system then set bids using conversion and elasticity models that explicitly accounted for product costs, margins, and demand patterns, with bid updates aligned to peak B2B demand windows.
This gave the brand granular control over spend by segment, budget pool, and fulfillment type while preserving centralized, model-driven optimization. The result was a system that could scale across thousands of ASINs without losing precision or financial discipline.
Results
Capline shifted the brand from their prior-agency baseline into a profit maximizing program covering roughly 95% of products, with bids constrained by a 2% margin floor and only a small minority of ASINs on ACoS targets.
Some key outcomes:
- Coverage: Ad coverage expanded from 24% of sales to 100% of sales, unlocking scale
- Keywords: There was also a 25x increase in keyword and product targets, plus gains from roughly 25K ASINs that previously had no ad spend at all.
Gross profit grew faster than revenue, and attributed contribution profit flipped from negative to positive as the system learned. That is exactly what a successful Profit Max program should do -- improve the quality of growth, not just the quantity.
