Why Seller Trust Matters on Amazon

Amazon's marketplace includes millions of third-party sellers. While most are legitimate, the open marketplace also attracts bad actors who list counterfeit products, fail to ship orders, or provide no after-sales support. Checking the seller before buying is one of the most effective ways to reduce risk.

What the Seller Checker Analyzes

Seller Identity

STG identifies who is selling the product — whether it is Amazon directly, a well-known brand, or a third-party reseller. Amazon-fulfilled and brand-direct listings generally carry lower risk than unknown third-party sellers.

Seller Age and Track Record

A seller who has been active for years with consistent positive feedback is generally more trustworthy than a seller who launched recently. STG surfaces how long the seller has been on the platform and flags new sellers as a potential risk signal.

Reseller vs. Original Brand

When a product is sold by a reseller rather than the original brand, there is a higher risk of counterfeit or grey-market goods. STG checks whether the seller appears to be the brand owner or a third-party reseller.

Trust Score Integration

Seller trust is one of several factors that contribute to the overall Trust Score. A product with excellent reviews but a brand-new, unknown seller may receive a lower score than the same product sold by an established brand.
