If you sell on Wildberries, Ozon, or Amazon — you already know: the one who sees changes in competitor prices first wins. However, marketplaces actively block automated data collection and suspicious activity from a single IP. Proxies solve this problem — not only for scraping but also for managing multiple seller accounts without the risk of being banned.
Why Marketplace Sellers Need Proxies
Trading on marketplaces has long ceased to be just about "listing a product and waiting." Today, it is a full-fledged competitive battle where data decides everything. Sellers who know competitor prices in real-time respond faster to market changes, occupy top positions in search results, and earn more.
But here arises a problem: Wildberries, Ozon, Amazon, and other platforms protect their data. They monitor suspicious activity — too frequent requests from a single IP address, automated information gathering, and working with multiple accounts from one location. The result is a temporary or permanent ban.
Proxy servers allow bypassing these restrictions. They replace your real IP address with another — clean, unexposed, from the desired region. For a seller on a marketplace, this opens up several opportunities:
- Scraping competitor prices without the risk of being banned — you can collect data on thousands of SKUs daily
- Monitoring search positions — see actual results from different regions
- Managing multiple seller accounts on one platform without their interconnection
- Checking your own listings from the perspective of a buyer in another city
- Working with regional prices — marketplaces often show different prices depending on the user's location
- Analyzing competitors' advertising campaigns — what banners and promotions they launch
According to surveys among active sellers, over 60% of sellers working with more than 100 SKUs use some form of automated monitoring tools. And almost all of them sooner or later face the need for proxies.
Competitor Price Monitoring: How It Works in Practice
Imagine: you have 200 items on Wildberries. Every day you need to check prices from at least 5 competitors for each product. That’s 1000 checks a day manually — unrealistic. A scraper can do this in a few minutes, but without proxies, it will be blocked after the first 50–100 requests.
Here’s how a typical price monitoring scheme using proxies looks:
- The scraper sends a request to the product page through a proxy server
- The proxy substitutes a clean IP from the pool — each request looks like an action from a new user
- Data is collected into a database — price, availability, rating, number of reviews
- The system compares your prices with competitors' prices and provides recommendations
- If necessary, you automatically adjust the price to maintain your position
For quality monitoring, IP address rotation is crucial. If the same IP makes 500 requests per hour — that’s a clear sign of a bot. But if 500 different IPs make one request each — it looks like regular traffic. That’s why scraping marketplaces uses proxy pools with automatic rotation.
💡 Practical Example
An electronics seller on Ozon monitors 300 competitive products every 2 hours. That’s 3600 requests per day. With a pool of 100 rotating residential proxies, each IP receives an average of 36 requests per day — absolutely unnoticed load for the platform. The result: up-to-date price data without a single ban.
For price monitoring on Russian marketplaces, residential proxies are well-suited — they have IP addresses of real home users, making requests as organic as possible. Wildberries and Ozon block such addresses significantly less often compared to data center proxies.
Managing Multiple Seller Accounts Without Bans
Many experienced sellers work with multiple accounts on one platform. The reasons vary: different legal entities, different product categories, testing pricing strategies, risk diversification. However, marketplaces strictly prohibit multi-accounting and actively detect it.
How do platforms determine that multiple accounts belong to one seller? They analyze:
- IP address — the most obvious marker. If two accounts log in from one IP, the connection is clear
- Browser fingerprint — screen resolution, fonts, plugins, OS version
- Cookies and cache — traces of previous sessions
- Behavioral patterns — login times, sequence of actions
- Payment data — one card used on different accounts
- Device data — MAC address, serial number
Proxies cover the first and most important point — the IP address. But proxies alone are not enough for full protection. This is where anti-detect browsers come into play. The most popular among sellers are: Dolphin Anty, AdsPower, Multilogin, and GoLogin.
Each account gets a separate profile in the anti-detect browser with a unique fingerprint and a separate proxy. For the platform, this looks like different devices and different users. It is important to follow the rule: one account — one proxy — one browser profile. Never mix them.
⚠️ Important to Know
If one of your accounts gets banned — immediately stop using it. Do not try to log into other accounts from it. Marketplaces track "chains" of linked accounts and can ban the entire group at once (the so-called chain-ban).
Which Types of Proxies Are Suitable for Marketplaces
Not all proxies work equally well with marketplaces. The choice depends on the specific task. Let’s consider the main types and their applicability:
| Proxy Type | Price Monitoring | Multi-Accounting | Speed | Cost |
|---|---|---|---|---|
| Residential | ✅ Excellent | ✅ Excellent | Average | Above Average |
| Mobile | ✅ Excellent | ✅ Excellent | Average | High |
| Data Center | ⚠️ Risks | ❌ Not Recommended | High | Low |
Residential proxies — IP addresses of real home internet users. Marketplaces see them as regular buyers. They are suitable for both scraping and multi-accounting. The main downside is that they are more expensive than data center proxies.
Mobile proxies — IP addresses from mobile operators (MTS, Beeline, MegaFon, Tele2). These are the "cleanest" addresses in terms of platform trust: one mobile IP is actually used by hundreds of people simultaneously, so marketplaces cannot block it without a huge number of false positives. Ideal for managing seller accounts.
Data center proxies — the fastest and cheapest, but easily identified as non-human traffic. Wildberries and Ozon actively block ranges of data center IPs. They are not suitable for multi-accounting. For scraping — only with very cautious rotation and low request frequency.
Features of Working with Wildberries and Ozon
Russian marketplaces have their own protection specifics, which is important to understand before starting work.
Wildberries
WB is one of the most aggressive in terms of protection against scraping. The platform uses several levels of protection:
- Rate limiting — limiting the number of requests from one IP. Usually triggers after more than 30–50 requests per minute
- Captcha — appears during suspicious activity. Modern scrapers can bypass it, but it slows down the process
- Blocking IP ranges — entire data center subnets are already blacklisted
- Request header analysis — non-standard User-Agent or absence of usual browser headers immediately raises suspicion
- JavaScript checks — some pages require JS execution, which filters out simple HTTP scrapers
For working with WB, it is recommended to use residential proxies with Russian IP addresses, imitate real user behavior (pauses between requests, random order), and use headless browsers instead of simple HTTP requests for complex pages.
Ozon
Ozon is somewhat less aggressive in protection but also has its specifics:
- Uses Cloudflare to protect against bots — this means additional checks on the first request
- Prices may vary depending on the user's region — for accurate monitoring, proxies with the necessary geolocation are needed
- Category and search pages are more resistant to scraping than individual product pages
- Ozon Seller — the seller's personal account — has a separate protection system. Working with multiple accounts requires strict IP separation
📌 Geolocation Tip
Both WB and Ozon show different prices and availability of products depending on the user's region. If you want to see prices as a buyer in Moscow, St. Petersburg, or Yekaterinburg sees them — choose proxies with the corresponding geolocation. This is especially important when analyzing competitors in specific regions.
Proxies for Amazon: Specifics and Setup
Amazon is a global marketplace with one of the most developed bot protection systems. If you work with Amazon as a seller or engage in arbitrage (retail arbitrage, wholesale), proxies become a necessary tool.
The main tasks for which Amazon sellers use proxies:
- Monitoring Buy Box — tracking who owns the buy button for your products
- Analyzing competitors by BSR (Best Seller Rank) — sales dynamics by categories
- Checking listings from different countries — prices on Amazon.com, Amazon.de, Amazon.co.uk can vary significantly
- Managing multiple Seller Central accounts — Amazon is extremely strict about multi-accounting
- Working with tools like Helium 10, Jungle Scout via proxies to bypass regional restrictions
Amazon uses a complex bot detection system, including TLS fingerprint analysis, behavioral analysis, and reputation databases of IP addresses. For working with Amazon, residential proxies with IPs from the country where you are selling are strongly recommended. Using Russian IPs for Amazon US or Amazon EU significantly increases the risk of being banned.
A separate story is Amazon Seller Central accounts. Amazon links accounts by IP, cookies, payment methods, and even behavioral patterns. If you have multiple seller accounts (which is only allowed with different brands and Amazon's approval), each must operate through a separate proxy and a separate browser profile in an anti-detect browser.
Ready-Made Tools for Sellers: Scrapers and Anti-Detect Browsers
The good news: you don’t need to be a programmer to use proxies for working with marketplaces. There are many ready-made tools with intuitive interfaces.

Anti-Detect Browsers for Multi-Accounting
For managing multiple seller accounts, an anti-detect browser is an essential tool. Here are the most popular options among sellers:
- Dolphin Anty — popular among Russian-speaking users, user-friendly interface, good integration with proxies, free tier for up to 10 profiles
- AdsPower — widely used for e-commerce, supports automation through a built-in RPA tool
- Multilogin — one of the oldest and most reliable, used by large teams, high cost
- GoLogin — an affordable alternative with cloud storage for profiles, convenient for team collaboration
- Octo Browser — relatively new but quickly gaining popularity among marketplace sellers
Step-by-Step Proxy Setup for Working with Marketplaces
Let’s break down specific setup scenarios — without programming, only through ready-made tools.
Scenario 1: Setting Up Proxies in Dolphin Anty for Managing Accounts on WB
- Open Dolphin Anty and click "Create Profile"
- In the "Proxy" section, select the type — SOCKS5 (recommended) or HTTP
- Enter proxy details in the format:
IP:port:username:password - Click "Check Proxy" — ensure the correct IP and country (Russia) are displayed
- Set the User-Agent to Windows 10 + latest version of Chrome
- Save the profile and launch the browser
- Log into your WB or Ozon Seller personal account
- For each subsequent account — create a new profile with a different proxy
Scenario 2: Connecting Proxies to a Price Scraper (using MPStats as an example)
- Log into your MPStats personal account
- Go to "Settings" → "Proxy"
- Add the list of proxies in the format
http://username:password@IP:port - Enable automatic rotation — the system will automatically change IP with each request
- Set a delay between requests: recommended from 2 to 5 seconds for WB
- Run a test data collection for 10–20 products and ensure there are no blocks
- Scale to the entire product list
Scenario 3: Checking Competitor Prices from Different Regions
- Obtain proxies with IPs from the desired region (e.g., Moscow, St. Petersburg, Krasnodar)
- Open a browser with this proxy (can be through Dolphin Anty or a regular FoxyProxy extension)
- Go to WB or Ozon as a regular buyer
- Find your product or a competitor's product
- Compare the price, delivery conditions, and availability with what you see from your region
Common Mistakes and How to Avoid Them
Even experienced sellers make mistakes when working with proxies. Here are the most common ones — and how to avoid them:
❌ Mistake 1: Using One Proxy for Multiple Accounts
This is the most common cause of chain bans. The marketplace sees that different accounts log in from one IP and blocks them all at once. The rule is strict: one account — one proxy.
❌ Mistake 2: Too High Request Frequency
Even with proxy rotation — if you make 1000 requests per minute, it’s noticeable. Set reasonable pauses: 2–5 seconds between requests on WB, 1–3 seconds on Ozon. Imitate real human behavior.
❌ Mistake 3: Proxies from Another Country for Russian Marketplaces
Logging into Wildberries Seller from a German or American IP immediately raises suspicion. For Russian marketplaces, use only Russian proxies. For Amazon US — American ones. The geolocation of the proxy must match the platform.
❌ Mistake 4: Cheap Public Proxies
Free and cheap public proxies have long been blacklisted by all major platforms. Moreover, they are unsafe — your login data can be intercepted. Use only paid private proxies from reliable providers.
❌ Mistake 5: Forgetting About Browser Fingerprint
Changing IP without changing the browser fingerprint is a half-measure. If you manage multiple accounts, be sure to use an anti-detect browser. Otherwise, the marketplace will link accounts by device parameters, even if the IPs are different.
❌ Mistake 6: Ignoring Proxy Change After a Ban
If an account gets banned — the IP that was used to log in is now marked. Do not use it for other accounts. Get a new clean proxy.
Safe Start Checklist
- ☑ Chose residential or mobile proxies with Russian IPs
- ☑ Each account received a separate proxy
- ☑ Installed an anti-detect browser (Dolphin Anty / AdsPower / GoLogin)
- ☑ Created a separate browser profile for each account
- ☑ Set delays between requests in the scraper
- ☑ Checked the geolocation of the proxies before starting work
- ☑ Do not use one proxy for multiple accounts
- ☑ Do not log into accounts from your real IP
Conclusion
Proxies for marketplaces are not a technical whim, but a practical tool for competitive struggle. Sellers on Wildberries, Ozon, and Amazon who use automated price monitoring and manage multiple accounts wisely gain a real advantage: they respond faster to market changes, maintain positions in search results, and scale their business without unnecessary risks.
Key takeaways from this article:
- For price monitoring and data scraping on WB and Ozon, use residential proxies with Russian IPs
- For managing seller accounts — a combination of proxies + anti-detect browser is essential
- For Amazon, choose proxies with geolocation from the country where you are selling
- The rule "one account — one proxy" must not be violated
- Mobile proxies are the safest option for working with accounts, residential ones for scraping
If you are just starting to build a competitor monitoring system or plan to work with multiple seller accounts, we recommend starting with residential proxies — they provide the optimal balance between reliability, speed, and trust level from the platforms. And if your main task is safe account management on WB or Ozon without the risk of bans, pay attention to mobile proxies: they closely mimic the traffic of real buyers and are practically immune to marketplace blocks.
