Mobile Proxy Brand Protection
Counterfeits and unauthorised sellers surface where the customer buys, and marketplaces show that page differently in every country. This guide covers separating the three problems, finding them from the markets they target, and capturing evidence that survives a challenge.
- Three different problems, three responses — a counterfeit, an unauthorised seller and a grey-market diversion are not the same finding.
- Listings are shown per country — an infringing offer aimed at one market is often invisible from anywhere else.
- Survival time is the metric — monitored brands do not get fewer counterfeits, they get counterfeits that last days instead of quarters.
- A screenshot is not evidence — without the exit IP, market and timestamp, a takedown becomes an argument about methodology.

Brand Protection Challenges
Brand protection programmes usually fail in one of two ways. Either they treat three quite different problems as one, and respond to all of them with the same ineffective action; or they monitor from one country and conclude, accurately, that nothing is wrong in that country.
The first problem is definitional. A counterfeit listing copies your name, images or trademarks to sell goods that are not yours. An unauthorised seller offers your genuine product without a current reseller agreement — very often stock diverted through grey-market channels. Trademark misuse in paid placements is a third thing again: somebody bidding on your brand terms to intercept your customers. Same brand, three violations, three entirely different responses.
| What you found | What it actually is | What the response looks like |
|---|---|---|
| Counterfeit listing | Goods that are not yours, sold using your marks and imagery | Intellectual-property notice and takedown, with evidence attached |
| Unauthorised seller | Genuine product, no current agreement — frequently grey-market diversion | A channel and contract matter, usually alongside a pricing breach |
| Grey-market diversion | Genuine stock sold outside its intended territory, often below local pricing | Trace the channel; a takedown treats the symptom and not the leak |
| Trademark misuse in ads | A third party bidding on your brand terms to intercept demand | Platform complaint, and it overlaps directly with ad verification |
The second problem is geographic. Marketplaces show different listings, different sellers and different search results depending on where the shopper is. An offer targeted at one market frequently does not appear to anyone outside it. A programme run from head office therefore produces clean reports for exactly the markets it cannot see, which is the worst possible failure mode: it looks like coverage.
Detecting Counterfeit Products
Every counterfeit and every diverted-stock route eventually resolves to the same place: the listing where your customer buys. That is the practical monitoring surface, and it is also where the useful evidence lives. Chasing the supply chain is slow and often outside your reach; watching the point of sale is neither.
The metric worth managing is not how many infringing listings exist. Monitored brands do not get fewer counterfeits than unmonitored ones — they get counterfeits that survive days rather than quarters. Survival time is what determines whether infringing at scale is worth anybody’s effort, and it is a cadence problem far more than a coverage problem.

Two details repay attention. Capture the whole page rather than the product image, because seller identity, shipping origin and the surrounding storefront are usually what distinguishes a counterfeit from a legitimate reseller. And record the shipping origin explicitly — for grey-market diversion it is frequently the only field that shows the stock left its intended territory.
Monitoring Unauthorized Sellers
Unauthorised selling is a slower, more structural problem than counterfeiting and it is often more expensive. The goods are genuine, so customers are not complaining. What suffers is the authorised network: a diverted channel undercuts your minimum advertised price, your legitimate resellers lose the sale, and eventually they stop defending the price at all.
Detection is mostly a matter of maintaining a current list of who is allowed to sell, and then continuously comparing it against who actually is — per marketplace and per market. The comparison is trivial. Keeping the authorised list current, and seeing the full seller set in each country, is the work.
- Watch the buy box and the full seller list — The default seller is only part of the picture; diversion often sits several rows down where nobody looks.
- Compare shipping origin against the territory — Genuine stock arriving from the wrong region is the clearest diversion signal you will get.
- Pair seller monitoring with price monitoring — An unauthorised seller and a minimum advertised price breach are usually the same event seen from two angles.
- Record first-seen and last-seen — Survival time is the metric your programme is actually managing, and you cannot report it without both timestamps.
Scaling Brand Protection Efforts
Coverage is tempting and cadence is what works. A weekly sweep of forty marketplaces finds problems long after the damage, while continuous watching of the four marketplaces and three markets where your infringements concentrate keeps survival times short enough to change the economics for the infringer.
Start by working out where your problem actually is, using whatever complaints, customer reports and channel data you already have. Put continuous monitoring on those markets, run a slower discovery sweep everywhere else, and let the discovery sweep promote a market into continuous coverage when it starts producing findings. That structure spends most of the budget where the return is, and still notices when the problem moves.
| Symptom | Most likely cause |
|---|---|
| A market reports clean for months, then a backlog appears | You were never seeing that market’s listings. Check the exit country you monitored from. |
| Takedowns are refused for lack of evidence | Captures lack provenance, or are cropped images rather than full pages. |
| The same seller returns under a new storefront | Expected. Track shipping origin and listing fingerprints, not storefront names. |
| Genuine product, undercut price, no counterfeit | Grey-market diversion. A takedown will not fix a supply leak. |
| Findings dry up abruptly across all markets | Your collection is being handled rather than blocked. Verify from a fresh address. |

Frequently Asked Questions
What is the difference between a counterfeit and an unauthorised seller?
A counterfeit listing copies your name, images or trademarks to sell goods that are not yours. An unauthorised seller is a merchant offering your genuine product without a current reseller agreement — frequently stock diverted through grey-market channels. The distinction matters because the responses differ entirely: one is an intellectual-property takedown, the other is a channel and contract problem, often accompanied by a minimum advertised price breach.
Why does brand monitoring need proxies in different countries?
Because marketplaces show different listings, sellers and search results depending on where the shopper is. An infringing offer targeted at one market may simply not appear to anyone outside it, so a monitoring programme run from a single location reliably reports that market as clean. Local addresses in the regions where the problem concentrates are what let you see what local customers see.
What should be captured for an enforcement action?
Enough for somebody else to reproduce the finding. That means the full listing page rather than a cropped image, the seller identity and storefront, the price and shipping origin, and — critically — the exit IP, the market and the timestamp behind the capture. Listings change and disappear, so a capture without provenance frequently cannot be defended a month later when the takedown is contested.
How often should marketplaces be checked?
Continuously for the marketplaces and markets where your problem concentrates, and on a slower sweep everywhere else. The goal is not to catch every listing at the moment it appears; it is to keep the average survival time short enough that infringing at scale stops being worth the effort. That is a cadence question long before it is a coverage question.
Does this overlap with ad verification?
They meet at trademark misuse. Ad verification asks whether your own campaigns ran as bought; brand protection asks who else is using your name — including in paid placements you did not buy, where a competitor or a counterfeiter bids on your brand terms. Both need requests that genuinely originate in the target market, which is why teams usually run them on the same infrastructure.
