Listing hijacking happens when another seller adds themselves to your product listing and starts selling — often with a lower price, counterfeit goods, or items that don't match your listing. It is one of the most frustrating experiences for private label sellers and brand owners on Amazon, and it can damage your sales, reviews, and brand reputation if not dealt with quickly.
How to Spot a Hijacker
The most obvious sign is a sudden drop in Buy Box percentage. If you were winning the Buy Box 100% of the time and it drops to 50% or lower, another seller has likely joined your listing. You can check this by looking at the "Other Sellers on Amazon" section of your product page, or by checking your Buy Box percentage in Business Reports.
Other signs include unexpected negative reviews mentioning product quality issues (the hijacker may be sending inferior products), a drop in conversion rate, or customer messages complaining about receiving the wrong item.
Immediate Steps to Take
First, purchase a unit from the hijacker. This gives you physical evidence of what they are selling. If it is counterfeit or materially different from your product, you have grounds for an intellectual property complaint. Document everything — photos of the product received, the packaging, and any differences from your genuine product.
Next, check whether the hijacker is actually violating any rules. If they are selling genuine, legitimately sourced units of your product (common in wholesale), they have every right to sell on your listing under Amazon's marketplace rules. This is frustrating but not hijacking in the intellectual property sense.
Filing a Complaint
If the hijacker is selling counterfeit goods, file an intellectual property complaint through Amazon's Brand Registry portal or through the Report a Violation tool. Provide your evidence — photos, test buy order number, and a clear explanation of how the product differs from your authentic item. Amazon typically investigates within a few days and will remove the seller if the complaint is substantiated.
If you are enrolled in Amazon's Transparency programme, this is where it pays off. Transparency codes on every unit prove authenticity, and any seller without codes cannot sell on your listing.
Prevention Is Better Than Cure
Enrol in Brand Registry and the Transparency programme. These are your two strongest defences. Monitor your listings regularly using alerts from tools like Helium 10 or Jungle Scout, which can notify you when new sellers join your listings. Keep your pricing competitive so that hijackers cannot easily undercut you. And maintain excellent product quality so that even if someone joins your listing legitimately, your reviews and reputation keep the Buy Box in your hands.
