A hijacker does not knock. One morning your best-selling ASIN shows a third seller on the listing, undercutting your price by a few dollars and winning the Buy Box you built. Or a customer leaves a one-star review about a product that smells wrong, feels cheap, and was never made by you. By the time you notice, the damage to conversion, ranking, and reputation is already moving.
Brand protection is not a one-time setting you flip on. It is a habit. The brands that lose the least are the ones watching every day and ready to respond in hours, not weeks. Here is the playbook we run for the brands we manage.
Know the two threats you are actually fighting
"Hijacker" and "counterfeit" get used interchangeably, but they are different problems with different fixes.
A hijacker is an unauthorized seller listing on your ASIN. Sometimes they ship genuine product they sourced through a gray channel. Sometimes they ship nothing close. Either way, they steal the Buy Box with a lower price, pocket the margin, and leave you holding the customer service and the reviews.
A counterfeit is a fake version of your product. It may sit on your listing or on a cloned listing under a different ASIN. The unit is not yours, the quality is not yours, but your brand name takes the hit.
The reason this matters: your response is different for each. A hijacker often folds under a test buy and a cease-and-desist. A counterfeit usually needs a formal infringement report and, in serious cases, Amazon's Brand Registry team or legal action. Treating both the same way wastes the first 48 hours, which are the hours that count.
Build the moat first: enrollment and a clean catalog
You cannot defend a listing you do not control. Before you monitor anything, close the easy doors.
Enroll in Amazon Brand Registry. It is the foundation for every protection tool that follows, and without it you are arguing with Seller Support instead of a team that recognizes you own the brand. Layer on Transparency or Project Zero if your category attracts counterfeits, so each unit carries a code Amazon can verify at the warehouse.
Then tighten the listing itself. Hijackers look for ASINs that are easy to copy and easy to confuse. A thin detail page with generic images is a soft target. A page with branded photography, a registered trademark in the title, and rich A+ content is harder to fake and easier to prove ownership of. This is one more reason the work in the five listing mistakes quietly costing you the Buy Box pays off twice: it lifts conversion and it raises your defensive wall at the same time.
Brand protection is not a legal task you outsource once a year. It is an operations habit you run every morning.
Monitor like you mean it
Most brands find out about a hijacker from an angry customer or a sudden dip in their numbers. That is two weeks too late. Set up monitoring so you catch the change on day one.
Watch these signals every day
- The Buy Box seller. Check your top ASINs daily. If a name you do not recognize holds the Buy Box, the clock has started.
- Offer count on the listing. A jump from one seller to three overnight is the clearest hijacking signal there is.
- Price movement you did not make. A sudden drop usually means someone is racing you to the bottom.
- Review velocity and sentiment. A run of one-star reviews mentioning packaging, smell, or "not as described" often points to counterfeit units in the supply.
- Account Health notifications. Authenticity complaints and intellectual property flags show up here first.
You can do this by hand for a small catalog. Past a few dozen ASINs, use a monitoring tool that pings you when the seller count or Buy Box owner changes. The goal is a same-day alert, not a monthly audit.
This is also where running your account as a connected system pays off. When the same team watches ads, listings, and account health together, a strange conversion dip gets traced back to a hijacker fast instead of being written off as a slow week. We made that case in full in running your Amazon account as one system, not four projects, and brand protection is one of the clearest examples of why the silos cost you.
Have the response ready before you need it
When you spot a problem, speed and documentation win. Decide your steps now so you are not improvising while a hijacker drains your Buy Box.
The hijacker response, in order
- Buy the unit. Place a test order from the unauthorized seller. This is your evidence and your proof of what they are actually shipping.
- Document everything. Screenshot the listing, the offer, the seller name, and the order. Save the packaging and the product when it arrives.
- Send a cease-and-desist. A direct, firm message citing your Brand Registry rights and trademark resolves a large share of cases. Many hijackers leave the moment they realize you are watching and organized.
- Report through Brand Registry. If they ignore you, file the violation with your evidence attached. A clean, documented report moves faster than a vague complaint.
The counterfeit response
For a counterfeit, escalate harder and faster. File an intellectual property infringement report, attach your trademark and your test-buy evidence, and request removal of the offer or the cloned ASIN. If Transparency is enabled, flag the units that failed verification. For repeat or large-scale counterfeiting, this is where legal counsel and Amazon's brand team earn their keep.
In both cases, keep one rule: respond to the customer first. Refund or replace any buyer who received a bad unit, even one that was not yours. Protecting the review and the relationship matters more than winning the argument with Amazon in the moment.
Protect the reputation, not only the listing
Winning the takedown is half the job. A hijacker or counterfeit run leaves a residue of bad reviews and a bruised conversion rate, and that residue keeps costing you after the seller is gone.
Once the listing is clean, treat the recovery like a relaunch. Watch the review profile, respond where you can, and rebuild the trust signals that drive the sale. The same levers that raise conversion in normal times do the repair work here, and we walk through them in how to lift conversion without touching your price. If the attack also triggered a suppression or compliance flag, work that thread in parallel using the calm, prioritized approach in what to do the day your listing gets suppressed.
Where to start this week
You do not need a legal team to begin. You need a routine.
- Confirm you are enrolled in Brand Registry, and add Transparency if your category invites fakes.
- Pick your top ten ASINs by revenue and check the Buy Box seller and offer count on each today. Note what normal looks like.
- Set a daily alert, by hand or by tool, on seller count and Buy Box ownership for those ASINs.
- Write your cease-and-desist template now, so it is ready to send in five minutes instead of five days.
Do those four things and you move from finding out late to catching it on day one. That single shift, from reactive to proactive, is the whole game in brand protection.
