The Unauthorized Seller Crisis: A Growing Threat to Brand Value
Revenue Impact
Unauthorized sellers who violate MAP pricing reduce your Buy Box ownership and organic sales. This wastes ad spend on listings outside your control and diverts revenue from authorized partners.
Channel Disruption
Persistent price violations may cause authorized retailers to drop your products and make wholesale partners question investments. Distribution leaks create channel conflict, hurting marketplace performance metrics.
Brand Damage
When inconsistent pricing occurs, customers become confused and often leave negative reviews from unauthorized seller experiences. This gradually erodes your premium positioning and damages trust with key retail partners.
Today's Marketplaces: A Perfect Ground for Unauthorized Sellers
Today’s marketplaces create ideal conditions for unauthorized sellers through multiple platforms with limited oversight, complex distribution networks, policy-exploiting tactics, and poor cross-channel visibility.
Without protection, your brand remains vulnerable—but with the right approach, these challenges can be overcome.
Measure Your Risk Exposure
How vulnerable is your brand to unauthorized sellers? Consider these key indicators:
- Number of unauthorized sellers currently listing your products
- Frequency of MAP violations across marketplaces
- Buy Box ownership percentage on key SKUs
- Distribution network complexity
