Perfectly legal and ethical ways to promote your products on marketplaces do not always comply with the platforms’ rules. For example, you may want to sell different types of products from separate accounts — such differentiation increases promotion efficiency and brings more organic traffic.
However, neither Amazon nor Walmart allows more than one seller account per person, except for rare cases (for instance, you can open two accounts if you establish two separate legal entities).
Amazon and Walmart allow sellers not only to list products but also to launch advertising campaigns on their marketplaces and partner websites. Two key points should be kept in mind:
If you break the rules and register two, three, or more accounts, the system will block them. Large marketplaces use advanced anti-fraud systems that detect multi-accounting very effectively. They also detect the use of proxies and VPNs quite well, so you can’t convincingly imitate another country with them alone.
For multi-accounting, an anti-detect browser is essential. First, it allows you to create and manage several accounts in parallel. Second, together with proxies, it lets you change your apparent location without the risk of de-anonymization.
An anti-detect browser provides each account with an isolated digital environment, including:
The combination of all these parameters is called a digital or browser fingerprint. This is what an anti-fraud system analyzes to identify a user who logs in again or tries to create multiple accounts.
Thanks to anti-detect technology, the marketplace perceives every account as a separate user — the anti-fraud system sees no signs indicating that all accounts belong to the same person.
When the “Auto” option is selected, the time zone, language, and geolocation automatically match the proxy.
The anti-detect browser synchronizes device and browser parameters with the user’s geolocation and local time, so the anti-fraud tracker cannot see that your real country differs from the one shown by the proxy. As a result, every marketplace account gains the system’s trust.
Fingerprint masking and substitution make it possible to perform the following tasks:
Open new accounts when restrictions appear or after an old one is banned. Without anti-detect protection, the anti-fraud system recognizes you and won’t let you create a new account.
Research competitors’ campaigns. You select target regions and create accounts for them, then search by keywords within the region and analyze the ad results and recommendations. This way, you discover the most successful sellers, products, and ad creatives with their text versions;
Launch and scale advertising campaigns on Amazon and Walmart. The amount of advertising you can run becomes practically unlimited, since anti-detect allows you to open dozens, hundreds, or even thousands of accounts.
Check localization across different GEOs. By setting a proxy for a chosen country, you can see how a foreign user views your product page, what keywords lead to it, and what competing offers appear nearby.
The same product page and its recommendations look different in different GEOs.
Anti-detect browsers also make it possible to select trusted accounts and manage reputation.
Amazon and Walmart assign each account a kind of rating score — a trust level. Random factors can affect it: a delayed shipment, a slow response to a buyer, or a negative review — and as a result, the seller’s rating may not be as high as desired. The higher the rating, the more organic traffic and purchases the account receives.
If you run many seller profiles, some of them will eventually become top-quality performers. Those are the ones you should focus on — place products there, launch ads, and so on. If you work with only one seller account, you may never reach that level of quality. High-quality accounts deliver maximum sales with minimal investment of time and money.
Anti-detect browsers can also help manage the reputation of a brand or seller. To improve reputation, a “farm” of accounts can be created through which positive reviews are published. This increases customer trust and boosts product ranking.
However, remember that review manipulation violates platform policies and can be detected by other indicators not related to the browser fingerprint — for example, automated posting patterns or AI-generated text. Therefore, such tactics should be used only defensively — when competitors artificially inflate negative reviews on your products and there is no other way to contest them.
An anti-detect is a powerful tool when working with marketplaces. But it requires proper configuration — otherwise the platforms’ tracking systems will detect multi-accounting and fingerprint spoofing. Below are a number of rules for correctly creating a digital profile (we’ll use Dolphin Anty as an example).
Use a proxy — no exceptions. Even if you operate from your own GEO, you still need a proxy connection to mask the IP. Without a proxy, anti-fraud systems will notice that all your digital profiles have different parameters but share the same Internet protocol, which is a red flag.
Upload or “grow” cookies. Without cookies, a digital profile looks suspicious — as if it were created just to register a new account. If you don’t have a cookie file, create a browser profile and use a bot to collect cookies automatically — it will quickly gather realistic cookie files.
Choose your real OS. Although you can emulate another operating system, we do not recommend doing so because the emulation can be detected at the level of system fonts. It’s better to use your actual operating system.
Leave technical parameters at the default. Dolphin Anty uses real user fingerprints, so the default combinations of technical parameters (RAM, GPU, etc.) look natural.
If you change any technical parameter manually without sufficient knowledge, or especially if you add random “noise,” the fingerprint quality may degrade and become suspicious to Amazon, Walmart, and similar trackers.
One exception is the WebGL Info field — there you can use the rotate arrows to select a GPU vendor/model that is consistent with the rest of the digital fingerprint.
Important! Anonymity depends on more than just the anti-detect. De-anonymization can happen for reasons beyond the browser fingerprint. Watch out for these leak points:
Knowing these leakage points will help you avoid de-anonymization and successfully operate multiple accounts on marketplaces.
Don’t assume that multi-accounting and anti-detect tools are needed only by large operations. Even small businesses and early-stage sellers understand that working on marketplaces often requires means of anonymity.
We therefore recommend an anti-detect browser that produces high-quality digital fingerprints and offers additional features that speed up marketplace workflows. One such solution is the Dolphin Anty product mentioned above.
