Several storefronts, kept separate
Sellers end up with more than one account for ordinary reasons — different brands, different regions, a business bought from someone else, a wholesale account beside a retail one. The platform's job is to work out which accounts belong together, and browsers make that easy.
Read your marketplace's rules first
Marketplaces differ on multiple accounts: some permit them outright, some on request, some only for distinct legal entities, some not at all. Isolation is how you keep separate businesses genuinely separate — it is not a way around a rule that says no. Getting this wrong risks the accounts themselves, which is a bigger loss than any tooling gain.
What platforms correlate on
Marketplaces correlate harder than most sites, because linked selling accounts are a real fraud vector for them. In rough order of how often it catches people:
| Signal | Notes |
|---|---|
| Payout bank details | The strongest link there is, and no browser setting touches it. Separate businesses need separate banking. |
| Business address & tax ID | Registered at the account level, again outside the browser. |
| Device fingerprint | Canvas, GPU, fonts — identical across every tab of one browser. |
| IP address | Two storefronts from one connection is an obvious pair. |
| Contact details | A shared phone or recovery email links accounts permanently. |
| Listing overlap | Identical photos and descriptions across storefronts are matched directly. |
Worth being blunt about: the first two are outside a browser's reach entirely. Isolation solves the device and network layer. If the accounts share a bank account, nothing here matters.
Setting it up
One profile per storefront, from day one
Retrofitting is painful — accounts opened together have already been seen together. New storefronts should get their own profile before the first login.
A stable address, in the right country
Selling accounts are long-lived, high-value and slow-moving, which argues for a static residential or ISP proxy in the market you actually sell into, held steady for the life of the account. Rotating addresses are worse than none here — an account that appears from a new city every week is exactly the pattern review teams look for. See residential vs datacenter.
Timezone that matches the market
A UK storefront whose browser reports a Karachi clock is a contradiction, and it costs nothing to avoid — the profile's timezone follows the proxy's tested location automatically.
Day-to-day habits
- Never open two storefronts in one profile, not even for a moment to check something. That is the mistake that cannot be undone.
- Keep working hours plausible. Six storefronts all active at 03:00 and idle by day is a pattern in itself.
- Write listings separately. Duplicated copy links storefronts through content, whatever the browser does.
- Export sessions before a machine change. Cookies move deliberately; do not rely on signing in fresh from a new device mid-season.
The repetitive parts
Once storefronts are separate, the daily work multiplies: checking orders, updating stock, answering the same question on six accounts. Building it once and running it across the group is what makes several storefronts practical for one person — no-code automation covers how, and staggering the runs matters as much as the automation itself.
Start with three
Three profiles free, permanently — enough for a couple of storefronts and a test profile, before deciding whether to license more.
