Methodology

These definitions describe how we calculate the metrics shown on the homepage.

Wasted spend cut (first 4 weeks)

Percentage reduction in ad spend on search terms with no orders after an eligibility threshold (e.g., ≥8 clicks) during the first 28 days after onboarding compared to the 28‑day baseline prior to onboarding. Reported as median across the cohort.

Relevant sales velocity

Rate of sales for queries judged relevant to the catalog (brand/ASIN‑aligned search intent) measured as units/day or revenue/day. Reported as median 30‑day change vs the 30‑day baseline prior to onboarding. Relevance is derived from mapping search terms to ASINs and excluding navigational or unrelated intent.

TACoS change (30 days)

Change in Total Advertising Cost of Sales (ad spend ÷ total revenue) over the first 30 days after onboarding relative to the 30‑day baseline. Reported as median.

Long‑tail coverage

Multiple by which the count of unique converting search terms increases in the first 30–60 days, focusing on profitable queries (below median CPC and at/under target ACOS).

Time to first impact

Median time from API connect to the first batch of approved changes applied (bids/budgets/ placements/negatives). We also show the 90th percentile (P90).

Cohort

n=27 accounts spending $25k–$500k/month on Amazon Ads, last 90 days. Outliers trimmed; results are shown as medians and ranges (IQR/P90) where applicable.
