What this audit checks
Listing completeness (visibility)
- Suppressed listings due to missing required attributes
- Bullet points <5 or shorter than 200 chars
- A+ content absent on flagship ASINs (top-50 by revenue)
- Backend search-term coverage <80% of byte limit
- Brand-registry-eligible ASINs without enrolment
Buy-box & competitiveness (revenue at stake)
- Buy-box ownership <85% on revenue-driving ASINs
- Buy-box loss reason mix (price / shipping / feedback / availability)
- Active third-party offers on private-label ASINs (hijack risk)
- ASINs out-of-stock with active ad spend (cross-references amazon_ads)
Account health (account-survival)
- Order Defect Rate trending toward 1% suspension threshold
- Late Shipment Rate >4%
- Cancellation Rate >2.5%
- Negative feedback velocity vs 30-day baseline
- Policy violation count + unresolved A-to-z claims
FBA economics (margin protection)
- ASINs aging toward long-term storage (>270 days)
- Referral-fee % outliers vs category benchmark
- Stranded inventory (no buy-box, has stock)
- Sell-through rate <0.5x category median (FBA fee bleed)
