You've invested heavily in building your product, optimizing your listing, and generating positive reviews. Then one day you check your Amazon Seller Central and discover something alarming: your sales have plummeted, you've lost the Buy Box, and an unknown seller is now the default offer on your own product listing. Welcome to the world of marketplace hijacking—one of the most frustrating and financially devastating challenges facing brand owners today.
What Is Listing Hijacking?
Listing hijacking occurs when an unauthorized seller attaches themselves to your product listing on a marketplace like Amazon. Instead of creating their own listing (which would require them to build reviews from scratch), they piggyback on your established listing, benefiting from all the work you've done to build product visibility and trust.
Types of Hijackers
- Counterfeit sellers: Sell fake versions of your product at lower prices
- Gray market sellers: Sell authentic products obtained through unauthorized channels
- Arbitrage sellers: Buy your products from retail outlets and resell them online
- Malicious competitors: Attach to listings to undercut your pricing or damage your brand
To understand the full financial impact of hijacking, read our analysis of how counterfeits impact your bottom line.
How Hijacking Damages Your Business
Immediate Revenue Impact
The most immediate impact is lost sales. On Amazon, the seller who wins the Buy Box captures approximately 83% of sales on that listing. When a hijacker undercuts your price by even a few cents, they can capture the Buy Box and your revenue disappears overnight.
Brand Damage from Counterfeit Sales
When hijackers sell counterfeit products, customers receive inferior goods they believe are authentic. This leads to:
- Negative reviews on your legitimate listing
- A-to-Z claims that damage your seller metrics
- Customer service burden from complaints about products you didn't sell
- Long-term brand reputation damage
Price Erosion
Hijackers typically compete on price, driving prices down across the marketplace. Even if you win back the Buy Box, you may have to lower your price to do so, compressing margins on every sale.
MAP Policy Violations
Unauthorized sellers aren't bound by your Minimum Advertised Price policies, which can create conflict with authorized retailers who are being undercut.
How Hijackers Operate
Understanding hijacker tactics helps you defend against them:
Finding Target Products
Hijackers typically target products that are:
- High-volume with strong sales velocity
- Well-reviewed with established credibility
- Easy to source from unauthorized channels or counterfeit manufacturers
- In categories with historically lax enforcement
Sourcing Products
Hijackers obtain products through various means:
- Counterfeit manufacturing: Ordering fakes from overseas factories
- Distributor leakage: Acquiring products from distributors selling outside authorized channels—learn how to prevent this in our supply chain vulnerabilities guide
- Retail arbitrage: Buying discounted products at retail and reselling
- Liquidation purchases: Buying customer returns or excess inventory
Winning the Buy Box
Once attached to a listing, hijackers win the Buy Box by:
- Pricing below the brand owner
- Using FBA for Prime eligibility
- Maintaining adequate seller metrics (at least initially)
- Ensuring inventory availability
Detecting Hijackers Early
The key to effective hijacker management is early detection. The longer a hijacker operates on your listing, the more damage they cause.
Manual Monitoring
At minimum, check your listings daily for:
- New sellers attached to your ASINs
- Buy Box status changes
- Price changes you didn't make
- Sudden drops in sales velocity
Automated Monitoring
For brands with more than a handful of products, manual monitoring is insufficient. Automated monitoring tools can:
- Scan your entire catalog continuously (24/7)
- Alert you immediately when new sellers appear
- Track Buy Box ownership over time
- Monitor pricing across all sellers
- Detect listing content changes
BrandedOps' Hijack Shield provides exactly these capabilities—automated monitoring, instant alerts, and streamlined enforcement workflows.
Removing Hijackers: A Step-by-Step Approach
For a complete enforcement framework, see our guide on building an effective takedown strategy.
Step 1: Document the Violation
Before taking action, gather evidence:
- Screenshots of the hijacker's offer on your listing
- Seller information (name, storefront URL)
- Pricing history showing their offers
- Any product condition or description discrepancies
Step 2: Conduct a Test Purchase
If you suspect counterfeiting, purchase the product from the hijacker. This provides:
- Physical evidence of the counterfeit (or confirmation of authenticity)
- Shipping information that may reveal the seller's identity and location
- Evidence for Amazon reports and potential legal action
Step 3: Send a Cease and Desist
Contact the seller through Amazon's buyer-seller messaging:
- Identify yourself as the brand owner
- State that they are not authorized to sell your products
- Request they remove their offer within 24-48 hours
- Note that you will escalate to Amazon and legal action if needed
Many unauthorized sellers will simply move on to easier targets when confronted.
Step 4: Report to Amazon
If the seller doesn't comply, report through official channels:
- Brand Registry Report a Violation tool: For enrolled brands
- Project Zero self-service removal: For qualified brands
- Seller Performance reports: For serious policy violations
Step 5: Legal Escalation
For persistent infringers, consider:
- Formal cease and desist from legal counsel
- Civil litigation for trademark infringement
- Coordinated action across multiple marketplaces
Review our legal landscape guide for enforcement options.
Preventing Hijacking in the First Place
Product Authentication
Make your products difficult to counterfeit:
- Unique packaging elements
- Serialization with verification systems
- Security features (holograms, special inks, tamper-evident seals)
Learn about GTIN and barcode ownership as a foundation for product authentication.
Distribution Control
Many hijacker issues trace back to distribution problems:
- Limit distribution to trusted, authorized partners
- Use distribution agreements with anti-diversion clauses
- Implement serialization to track product through the supply chain
- Regularly audit distributor compliance
MAP Policy Enforcement
A strong Minimum Advertised Price policy, consistently enforced:
- Removes price incentive for unauthorized selling
- Protects authorized retailers from being undercut
- Maintains brand value perception
Listing Optimization
Make your listing difficult to hijack:
- Register all product variations under your Brand Registry
- Use A+ Content that clearly identifies your brand
- Include authentication messaging in product images
- Maintain strong product reviews through great customer experience
Handling Persistent Hijackers
Some hijackers are sophisticated and persistent. They may:
- Create new seller accounts after being removed
- Operate from multiple accounts simultaneously
- Game Amazon's systems to avoid detection
- Use fulfillment networks to obscure their identity
Strategies for Persistent Cases
- Pattern recognition: Track hijacker behavior to identify when they reappear under new accounts
- Legal action: Pursue formal legal remedies that impose real consequences
- Source investigation: Trace the supply chain to stop counterfeits at their origin
- Amazon escalation: Work with Amazon's Brand Specialist teams for complex cases
The Role of Technology in Hijacker Defense
Effective hijacker defense at scale requires technology solutions that can:
- Monitor all your ASINs continuously without manual checking
- Alert you within minutes of new unauthorized sellers appearing
- Track patterns across multiple hijackers and time periods
- Automate initial enforcement steps like templated warnings
- Generate reports for legal action and Amazon escalation
Modern AI-powered detection systems can identify threats faster and more accurately than manual monitoring.
Measuring Your Hijacker Defense Success
Track these metrics to evaluate your anti-hijacking efforts:
- Time to detection: How quickly do you identify new hijackers?
- Time to removal: How long until hijackers are removed from your listings?
- Buy Box win rate: What percentage of time do you control the Buy Box?
- Recurrence rate: How often do removed hijackers return?
- Revenue recovery: How much revenue do you recover after removing hijackers?
