In descending order of weight:
- Transaction documents — buyer's orders, auction invoices, bills of lading, warranty claims with outcomes.
- Defect-and-remedy cycles — a problem plus its documented resolution outweighs any volume of frictionless praise.
- Verified-platform reviews — Google-verified and similar; treated as pattern evidence and always paraphrased with attribution.
- Our own test inquiries — response substance, fee itemization, disclosure behavior.
Unverifiable testimonials, including glowing ones, carry zero weight. That single rule filters most of the noise in this industry.
