Proxies for marketplaces

The storefront through a buyer's eyes

Marketplace search depends on location: rankings, prices with delivery, availability and sponsored blocks all change. Connect through an IP in the right country to check where your product ranks and what the listing looks like. For a specific city or carrier, turn on precise geo (traffic ×2).

Selling abroad

If you sell on international platforms such as Amazon or Etsy, check your listings from IPs in the countries you ship to. You'll see the real price with shipping, the currency and the competitors a local buyer sees. On Ukrainian platforms such as Prom, Rozetka or OLX, compare results across cities.

Several store accounts

If you run seller accounts for several of your own brands or for clients, give each one a separate connection in “Sticky session” mode and a separate antidetect browser profile. The guides for AdsPower and Dolphin Anty show how to add a proxy to a profile. Before you start, check whether the platform allows several stores per seller.

Residential for manual work

Marketplaces respond best to residential addresses, which are ordinary home connections. For one-off checks, “Rotating (new IP per request)” mode is enough; for work inside a seller account, use a stable IP. If you need to check prices in bulk, see the price monitoring page.

What a marketplace knows about a seller

When you register a store, the platform gets far more than an IP address: documents or company details, a bank account for payouts, a warehouse address, a phone number and an email. Technically it also sees the browser, cookies and device you log in from. Marketplaces check who is behind a store using all of this, not just the address.

So a proxy doesn't “hide” a seller or turn one business into several independent ones. Its job is more modest: give each seller account a stable address in the store's country so that logins don't jump between cities and countries. If a platform's rules forbid several stores per seller, a proxy doesn't change that. It doesn't guarantee an account won't be suspended either.

Setting up several store accounts

1. Create a separate residential proxy plan for each brand or client. Each plan has its own username, balance and statistics, so costs are easy to split.
2. In the generator, pick the country where the store is registered and “Sticky session” mode. A session duration of up to 120 minutes covers a working session.
3. Assign each store one line, meaning one port in the 10000–20000 range, and one antidetect browser profile. Besides AdsPower and Dolphin, there are guides for Octo Browser and Multilogin.
4. Before logging in, open the IP checker in the same profile: country, time zone and WebRTC should match.

This also helps teams. When the owner is in Kyiv, a manager in Lviv and a content editor in Odesa, the seller account sees logins from three cities. A shared profile with one port gives everyone who works on the store a single address. Better still, if the platform supports separate staff logins, each person signs in under their own.

Checking the storefront: what to watch for

For a one-off look at a listing or search results, “Rotating (new IP per request)” mode in the right country is enough. But a few details can make what you see differ from what a buyer sees.

• Delivery city. Some platforms take the city not from the IP but from profile settings or cookies. Check in a clean profile without logging in, or pick the delivery city manually.
• Personalisation. Results for a signed-in user depend on their history. For an objective picture, browse without logging in.
• Precise geo. City, region or carrier are available in advanced mode. Precise-geo traffic counts ×2, so only use it where price or delivery really depends on the city.
• Sponsored slots. Paid positions in search change from one view to the next. Look at the same results from several addresses before deciding a competitor is “always on top”.

It helps to record results: a screenshot with the date, city and query, plus a weekly table of positions for your main queries. That way you see how a listing moves after new photos, prices or reviews, not just a one-off snapshot.

Bulk checks: frequency, errors, traffic

When you need to review hundreds of listings every day, work like a script, not a person with a browser. Datacenter addresses at $0.80 per GB fit here, and residential ones for sites that respond with captchas.

• Moderate frequency. Pause between requests and don't open dozens of pages from one store per second. You put less load on the platform and hit limits less often.
• Error 429 means “too many requests”: wait and slow down rather than just switching IPs.
• Error 403 often means the site blocks datacenter addresses. Try residential ones, or turn on the anonymity filter in the pool settings: it drops IPs that websites have already flagged as proxies.
• Retries. If a page fails, retry from a new address 2–3 times, then skip it and log it. Endless retries just burn traffic.
• Saving traffic. Turn off images, fonts and video, and request only the pages that carry the price. Traffic counts in both directions, so every extra megabyte is paid for.

Connection examples are in the Playwright and Octoparse guides; for more on collecting prices, see the price monitoring and web scraping pages.

Which proxy for which seller task

Traffic figures are rough: pages with lots of photos weigh more.

Residential proxies cost $1.59 per GB, datacenter $0.80. The price is the same for any volume; details are on the pricing page.

Countries and limits

For Ukrainian platforms, sellers use Ukraine with a city selected. Selling in the EU usually calls for Poland, Germany, Czechia and Italy; for Amazon and Etsy, the USA and the United Kingdom. You can choose any of 195 countries at no extra cost.

If a store sells into several countries, keep the two roles of a proxy apart. For logging in to the seller account, stick to one address in the country where the seller is registered. Use the sales countries only for storefront checks, in clean profiles without logging in.

Some websites are closed to all customers: banks, payment systems and government services. So open payouts, the store's bank details and tax accounts from your regular connection. The full list is on the blocked sites page.

Also keep in mind that the pool is shared: another customer may have used an address before you. And a fixed residential IP can change before the set time if the device goes offline. The port then gets a new address in the same country, so take a second to check the IP before important actions in a seller account.

Best proxies for Amazon, eBay and Walmart

The best proxies for Amazon, eBay or Walmart are residential IPs from the marketplace's own country: the US for Amazon.com and Walmart, Germany for Amazon.de, Japan for Amazon.co.jp. Sellers use them to keep each store account on its own sticky IP; analysts use them to see listings and prices as a local shopper does.
