Listing Hijacking
Unauthorized sellers attach themselves to an established marketplace listing to piggyback on its reviews and ranking, then ship counterfeit or inferior products.

Listing hijacking occurs on open-catalog marketplaces where multiple sellers can offer the same product under one listing. A fraudster identifies a high-ranking, well-reviewed listing for a legitimate product and joins it as a seller—sometimes by obtaining a suspiciously low-cost version of the product to game price-matching algorithms and win the 'buy box.' Buyers who trust the listing's existing reviews then receive counterfeit, substandard, or entirely different items.
Because the reviews are genuine (for the original seller's product) and the listing page appears legitimate, consumers have no obvious reason to distrust the purchase. The damage falls on both the consumer and the original seller, whose brand reputation suffers from negative experiences they did not cause.
Brand owners and legitimate sellers combat listing hijacking by monitoring their product listings for unauthorized sellers, using brand-registry programs, and enrolling in anti-counterfeiting tools offered by major platforms. Buyers who receive a product inconsistent with its listing should report the specific seller immediately.
Examples
- A well-reviewed kitchen appliance listing was joined by a fraudulent seller who won the buy box with a lower price, then shipped an unbranded imitation to buyers who trusted the original reviews.
- An original brand owner found their Amazon listing shared by dozens of unauthorized sellers shipping counterfeit units under the same product page.
