Listing Hijacker
A listing hijacker is an unauthorized third-party seller who attaches to your Amazon ASIN — often selling counterfeit, gray-market, or undercut units — to steal your Buy Box, siphon your sales, and erode your brand reputation.
How Listing Hijacking Works
- A seller finds your live listing on Amazon.
- They click Sell on Amazon and match your ASIN, listing under the same product page.
- Their offer competes for the Buy Box, usually by undercutting your price.
- Shoppers buy from them expecting your brand quality.
- Negative reviews, returns, and A-to-z claims land on your listing.
Signs You’ve Been Hijacked
| Signal | What It Means |
|---|---|
| Sudden Buy Box loss | Another seller has taken the offer |
| Unexpected price drop | The hijacker is undercutting your list price |
| Reviews mentioning “wrong product” | Buyers received counterfeit or repackaged units |
| A new seller name on your offer page | An unauthorized seller has attached |
| Sales dip without a traffic change | Sessions are converting to a competing offer |
| Listing edits you didn’t make | The hijacker has altered your content |
