Counterfeiters no longer need their own ecommerce site to reach customers. They can move between major marketplaces, social commerce, standalone stores, paid ads, and new seller accounts as quickly as platforms remove individual listings.

That creates a different challenge for IP and brand protection teams. Finding an infringing listing is only one part of the job. You also need to understand who is behind it, whether the seller operates elsewhere, and how quickly your team can enforce.

Marketplace brand protection is the process of detecting, investigating, and enforcing against counterfeit products, trademark misuse, unauthorized sellers, impersonation, and other brand abuse across online marketplaces.

According to the OECD and EUIPO’s Mapping Global Trade in Fakes 2025 report, counterfeit and pirated goods represented an estimated $467 billion in global trade in 2021, equal to about 2.3% of global imports.

For brands selling through Amazon, AliExpress, Shopee, TikTok Shop, Walmart Marketplace, and other platforms, the question is no longer whether marketplace abuse exists. The question is how efficiently your team can find it, prioritize it, and remove it.

Key Takeaways

• Marketplace brand protection goes beyond finding counterfeit listings. It includes seller analysis, evidence collection, prioritization, and enforcement.
• Counterfeiters can move between marketplaces, social media, standalone stores, ads, and new seller accounts.
• AI can help identify suspicious listings at scale, but human validation still matters before enforcement.
• Repeat sellers and connected seller networks are often more important than any single listing.
• The strongest programs measure removal, recurrence, seller behavior, and enforcement outcomes, not just detections.

This article, together with our free Marketplace Brand Protection Guide, explains the main risks and the practical steps you can take to strengthen your program.

What Are the Main Marketplace Brand Protection Risks?

The main marketplace risks include counterfeit products, trademark and copyright infringement, unauthorized sellers, fake storefronts, impersonation, and coordinated seller networks.

The mistake teams often make is treating each listing as an isolated infringement. In practice, the same operator may control several seller accounts, reuse product images, advertise through social media, and direct buyers toward a separate ecommerce site.

1. Trademark and Copyright Infringement

Counterfeiters frequently misuse brand names, logos, product photography, packaging, and copyrighted descriptions to make listings appear legitimate.

For your team, the challenge is separating clear infringement from legitimate resale or nominative use. Evidence matters, especially when enforcement depends on a specific trademark, image, or copyrighted asset.

2. Counterfeit Listings Using AI-Generated Content

AI tools make it easier to generate product imagery, listing copy, advertisements, and storefront content at scale. That can help counterfeit sellers create more polished listings and change creative assets quickly when old ones are removed.

Detection therefore needs to look beyond exact keyword matches. Image recognition, logo detection, pricing, seller history, product attributes, and repeated imagery can all help identify suspicious listings.

BrandShield’s Online Counterfeit Protection combines visual and text-based analysis with seller monitoring and enforcement.

3. Unauthorized and Gray Market Sellers

Gray market sales involve genuine products sold outside a brand’s authorized distribution network. They are not automatically counterfeit or unlawful.

However, unauthorized sellers can create pricing conflicts, warranty confusion, channel disputes, and customer-service problems. Your enforcement strategy should therefore distinguish between counterfeiting, contractual distribution issues, trademark misuse, and lawful resale.

4. Fake Customer Support and Impersonation Accounts

Fraud does not always happen through the product listing itself. Attackers can impersonate customer-service teams, sellers, or brand representatives and use those identities to collect payment details, credentials, or personal information.

That means marketplace protection increasingly overlaps with social media scam protection and broader impersonation monitoring.

5. Marketplace Account Impersonation and Seller Networks

Counterfeiters can create storefronts that reuse legitimate brand names, logos, product descriptions, and imagery. When one seller disappears, another account may replace it.

This is why seller-level analysis matters. If several accounts share images, contact details, products, payment information, or other signals, they may belong to the same operation.

Why Is Marketplace Counterfeiting Still Difficult to Control?

Marketplace counterfeiting remains difficult because sellers can operate across borders, use multiple accounts, ship in small parcels, and move between platforms when enforcement occurs.

The OECD and EUIPO found that shipments containing fewer than ten items represented 79% of counterfeit seizures in 2020 and 2021, up from 61% in 2017 to 2019, according to the Mapping Global Trade in Fakes 2025 report.

Small shipments make enforcement harder because counterfeit activity can be distributed across many sellers, orders, and fulfillment routes rather than concentrated in one large shipment.

The U.S. Trade Representative’s 2025 Notorious Markets Review, released in March 2026, identified 37 online markets and 32 physical markets reported to engage in or facilitate substantial trademark counterfeiting or copyright piracy.

USTR also noted that the online ecosystem now includes ecommerce and social commerce sites alongside other services that can support infringing activity.

Southeast Asia

Marketplace risk varies significantly by country and platform. For example, USTR’s previous Notorious Markets reporting identified continuing concerns around counterfeit availability on several Shopee country platforms, while also recognizing improvements in IP reporting tools and seller verification.

For brands selling across Southeast Asia, this means enforcement should be assessed at the individual marketplace and country level rather than treating the entire region as one risk category.

China and Hong Kong

China and Hong Kong remain important parts of the global counterfeit supply chain. The OECD and EUIPO reported that they accounted for the highest value of seized counterfeit goods in the data analyzed for the 2025 report.

However, origin data should not be confused with where counterfeit products are ultimately sold. Seller accounts, fulfillment infrastructure, and customer-facing storefronts may operate in completely different markets.

United States and Global Marketplaces

Large platforms serving U.S. consumers also face counterfeit, unauthorized seller, impersonation, and social-commerce risks.

For rights holders, the practical issue is not whether a platform has an IP reporting system. Most major marketplaces do. What matters is how quickly your team can identify violations, collect evidence, submit the correct complaint, and detect the same seller when they return.

What Does Marketplace Brand Protection Look Like in Practice?

A useful marketplace brand protection program connects detection with investigation and enforcement instead of measuring success only by the number of listings found.

A published BrandShield engagement with Ferrara shows how this can work across channels.

Over a three-month period, BrandShield reported 1,319 fraudulent listings and removed 1,221 of them, resulting in a 92.7% takedown success rate, according to BrandShield’s Ferrara success story.

The activity spanned social media and marketplaces, including products marketed as THC-related, freeze-dried, or packaged in fake candy-style bags.

“BrandShield’s staggering ~90% takedown success rate of our fraudulent online listings, speaks for itself.”

The important point is not just the percentage. The program combined monitoring, validation, and enforcement across more than one channel.

That is often where marketplace programs gain the most value. A seller account may be only one part of a wider network.

How Should You Build a Marketplace Enforcement Strategy?

A strong enforcement strategy starts with your rights, your priority marketplaces, and a consistent process for turning suspicious findings into verified cases.

If your team is reviewing hundreds or thousands of listings, trying to remove everything at once is rarely the best starting point. Prioritize the activity most likely to harm customers, revenue, distribution, or brand trust.

1. Map your rights. Document trademarks, copyrights, product imagery, packaging, and authorized sellers before enforcement begins.
2. Prioritize marketplaces. Focus first on the platforms, countries, and product categories creating the greatest commercial or consumer risk.
3. Validate suspicious listings. Use seller information, imagery, pricing, product details, test buys where appropriate, and other evidence before submitting complaints.
4. Look beyond individual listings. Track repeat offenders and identify seller networks that share accounts, imagery, contact details, or other signals.
5. Use the correct enforcement route. Trademark infringement, copyright abuse, counterfeit products, and unauthorized resale may require different approaches.
6. Measure recurrence. Track whether removed sellers or products return through new accounts rather than treating every takedown as the end of the case.

BrandShield’s Marketplace Brand Protection is designed around this workflow, combining AI-powered detection, seller analysis, visual recognition, prioritization, and expert-led enforcement.

The Role of Expert Brand Protection Solutions

At marketplace scale, manual searches alone are difficult to sustain. A brand may need to monitor many marketplaces, languages, product categories, sellers, and visual variations at the same time.

Technology can help your team:

• Monitor multiple marketplaces continuously
• Identify copied logos, product imagery, packaging, and other visual assets
• Analyze sellers and related listings
• Prioritize high-risk cases
• Preserve evidence for enforcement
• Track takedown outcomes and repeat offenders

However, automation should not turn every suspicious listing into an automatic enforcement action. Context still matters.

BrandShield combines automated detection with human validation and expert-led enforcement. Its broader Online Brand Protection platform also helps connect marketplace abuse with websites, social media, domains, paid ads, and other external channels.

Marketplace Brand Protection FAQ

What is marketplace brand protection?

Marketplace brand protection is the process of monitoring ecommerce platforms for counterfeit products, trademark misuse, unauthorized sellers, impersonation, and other forms of brand abuse. It also includes investigation, evidence collection, seller analysis, and enforcement against confirmed violations.

How do brands detect counterfeit marketplace listings?

Brands can use keywords, product details, seller information, pricing, logos, packaging, and image recognition to identify suspicious listings. Human review or test buys may still be needed when the evidence is unclear.

Are unauthorized sellers always infringing?

No. An unauthorized seller may be selling genuine goods lawfully, depending on the market and circumstances. Your team should distinguish gray market activity from counterfeiting, trademark infringement, contractual issues, and other violations before enforcement.

Why do counterfeit sellers return after takedowns?

Sellers can create new accounts, change names, move to another marketplace, or reuse the same products through connected storefronts. That is why repeat-offender tracking and seller-network analysis are important parts of marketplace protection.

Can marketplace brand protection cover social media and websites too?

A broader online brand protection program can connect marketplace listings with fake websites, social profiles, paid ads, domains, and other external assets. This helps teams investigate the wider operation instead of responding to each listing separately.

Final Thoughts

Marketplace brand protection in 2026 is not simply about finding more counterfeit listings.

Your team needs to know which sellers create the most risk, how infringement moves between platforms, which cases deserve enforcement first, and whether removed operators keep returning.

AI and automation can make detection faster. However, validation, evidence, seller analysis, and enforcement remain essential if those detections are going to produce meaningful results.

For IP professionals and brand managers, the goal should be a repeatable system that moves from detection to investigation to enforcement, while giving you a clearer view of the networks behind the listings.
