Methodology

Full transparency on how we collected and analyzed the data

Data Collection

All metrics collected via Amazon Advertising API with daily granularity. Pre-automation baseline established from historical campaign data before AdFixer activation. For new product launches, performance is measured against category benchmarks.

Cohort Selection

Data aggregated from AdFixer managed and self-serve accounts across 8 Amazon marketplaces. Cohorts defined by monthly ad-attributed revenue. Analysis includes both existing campaign takeovers and new funnel launches.

Metric Definitions

ACOS (Advertising Cost of Sale)
Ad spend divided by attributed sales. Lower is better. Industry average: 25-35%.
ROAS (Return on Ad Spend)
Attributed sales divided by ad spend. Higher is better. Industry average: 3-4x.
Wasted Spend
Spend on keywords with zero conversions over 14+ days with sufficient impressions (>1000). Identified and eliminated by AI.
Time to Value
Days from AdFixer activation to first month with measurable ACOS improvement or profitable scaling.
Revenue Growth
Percentage increase in ad-attributed sales comparing before/after periods of equal length.

Study Limitations

  • Results vary by category, competition level, and product margins
  • External factors (seasonality, inventory, pricing) can influence outcomes
  • New product launches measured against targets rather than baseline
  • Individual results may differ from aggregate averages

Metrics derived from documented case studies with verifiable Amazon Advertising data. Full case studies available at adfixer.com/case-studies.
