Methodology

How These Benchmarks Were Compiled

These benchmarks are derived from CSB Concepts' proprietary portfolio data across 100+ actively managed Amazon brands spanning the supplement, health & wellness, beauty, consumer product, and food & beverage categories on Amazon's U.S. marketplace.

All performance data reflects accounts managed using CSB Concepts' proprietary AI-powered advertising and optimization systems from January 2025 through March 2026. Manual management benchmarks are based on pre-onboarding performance data from these same brands before transitioning to AI-managed operations.

ROAS figures represent blended return on ad spend across Sponsored Products, Sponsored Brands, and Sponsored Display campaign types. Revenue growth is measured as the percentage increase in total Amazon revenue comparing the 12-month period before and after AI management implementation.

For Amazon Brands

How to Use These Benchmarks

These benchmarks provide a clear performance baseline for Amazon brands evaluating whether their current advertising management approach is delivering competitive results. Compare your brand's current ROAS, conversion rate, and revenue growth trajectory against the category-specific benchmarks above. If your Amazon advertising is being managed manually and your ROAS falls below the 2.1x manual average, or if your AI-managed campaigns are underperforming the 4.2x AI benchmark, there is likely significant room for improvement. Brands consistently below these thresholds should evaluate whether their current management strategy, tooling, and optimization frequency are sufficient to compete in today's Amazon marketplace, where AI-driven competitors are setting the performance standard.
