How to Distribute Load Among Multiple Proxy Providers: Strategies for Arbitrage and Scraping

When working with dozens of accounts in Facebook Ads, managing an SMM agency, or scraping marketplaces, reliance on a single proxy provider becomes a critical risk. Technical failures, subnet blocks, or limit exhaustion can paralyze all operations. In this article, we will explore practical strategies for distributing load among several providers to ensure stability and minimize risks.

We will show specific balancing schemes for different tasks: from farming advertising accounts to mass scraping. You will learn how to properly combine providers, set up automatic rotation, and monitor the performance quality of each proxy source.

Why Use Multiple Proxy Providers

Working with a single proxy provider creates several critical risks for your business. Imagine this situation: you launched 30 advertising campaigns in Facebook Ads, each through its account with a proxy from one provider. Suddenly, the provider gets a block on an entire subnet of IP addresses — and all your accounts are at risk simultaneously.

Here are real problems faced by arbitrage specialists and SMM professionals when working with a single provider:

• Mass Subnet Blocks: Facebook and Google regularly ban entire ranges of IPs from known data centers. If all your accounts use proxies from one subnet, banning one account may lead to checks on the others.
• Technical Failures: Any provider can experience outages. If you have active campaigns running or important scraping tasks at that moment, downtime can cost serious money.
• Limit Exhaustion: When working with residential or mobile proxies, traffic is often limited. If you exceed the monthly limit with a single provider, operations come to a halt.
• Geographic Restrictions: One provider may not cover all the regions you need. To work with different geos, you need to connect additional sources.
• Different Quality for Tasks: Proxies that work great for Instagram may perform poorly for scraping Wildberries or vice versa.

Experienced arbitrage specialists use at least 2-3 providers simultaneously. For example, the main pool of accounts operates through Provider A (70% load), the backup pool through Provider B (20%), and Provider C is used for testing new combinations (10%). This scheme ensures continuity of operations even when one of the suppliers has problems.

Load Distribution Strategies

There are several proven strategies for load balancing between proxy providers. The choice depends on your task, budget, and the level of criticality for continuous operation. Let's consider each strategy with specific application examples.

Strategy 1: Main + Backup Provider (80/20)

This is the simplest and most popular scheme for beginners. You choose one main provider that handles 80% of the load and one backup for the remaining 20%. The backup provider serves as insurance in case of problems with the main one.

When to Use: Suitable for arbitrage specialists with 10-30 advertising accounts or SMM professionals managing up to 50 social media profiles. The budget is limited, but basic protection against failures is needed.

Example Setup for Facebook Ads: You have 25 advertising accounts. 20 accounts operate through residential proxies from the main provider, and 5 accounts through the backup. In the anti-detect browser Dolphin Anty, you create two template profiles with different proxies, duplicating the settings. If the main provider is unavailable, you quickly switch profiles to the backup proxies.

Strategy 2: Even Distribution (50/50 or 33/33/33)

The load is evenly divided between two or three providers. This strategy is suitable when you do not fully trust any single supplier or work in high-risk niches where maximum diversification is essential.

When to Use: For large operations in arbitrage (50+ accounts), scraping marketplaces with high loads, or when working in countries with strict restrictions.

Example for Scraping Wildberries: You need to scrape 100,000 product cards daily. You divide the task among three providers: Provider A scrapes the "Electronics" category (33,000 cards), Provider B scrapes "Clothing" (34,000), and Provider C scrapes "Home and Garden" (33,000). If Wildberries blocks the subnet of one provider, you will lose only a third of the data, not the entire scraping.

Strategy 3: Task-Based Division

Each provider is responsible for a specific type of task. For example, one provider is used only for farming accounts, another for launching active advertising campaigns, and a third for scraping and analytics.

When to Use: When you have heterogeneous tasks with different requirements for proxies. Farming accounts require high IP trust, active advertising needs stability, and scraping requires speed and cost-effectiveness.

Example for TikTok Ads Arbitrage: Provider A (mobile proxies) is for warming up new TikTok accounts, simulating real activity. Provider B (residential proxies) is for launching advertising campaigns in TikTok Ads Manager. Provider C (data center proxies) is for scraping competitors and gathering creatives. Each type of proxy is optimal for its task.

Strategy 4: Geographic Distribution

Providers are distributed by geographic regions. One provider covers the USA and Canada, another covers Europe, and a third covers Asia and Latin America.

When to Use: For international arbitrage or multi-regional SMM. Not all providers cover all countries equally well.

Example for Instagram SMM: You manage client accounts from different countries. Provider A specializes in the USA and provides quality IPs from New York and Los Angeles — you use it for American clients. Provider B is strong in Europe — for clients from Germany, France, and Spain. Provider C covers the CIS — for Russian-speaking accounts. Each account receives a proxy from its region, which reduces the risk of blocks.

How to Combine Proxy Types from Different Providers

Besides distributing among providers, it's important to correctly combine proxy types. Residential, mobile, and data center proxies have different characteristics, and their proper combination enhances operational efficiency.

Combination for Facebook Ads Arbitrage

A classic scheme for farming and launching advertising campaigns includes two to three types of proxies from different providers:

• Mobile Proxies (Provider A): Used for initial registration of Facebook accounts and warming them up for 7-14 days. Mobile IPs have maximum trust, as Facebook sees them as regular smartphone users. At this stage, you fill out the profile, add friends, and like posts.
• Residential Proxies (Provider B): After warming up, the account is switched to residential proxies for launching advertising campaigns. Residential IPs are more stable than mobile ones (they do not change every 10-15 minutes) and are cheaper, which is important for long-running campaigns.
• Data Center Proxies (Provider C, optionally): For auxiliary tasks — scraping competitor audiences, gathering targeting data. For these tasks, high trust is not needed; speed and low cost are essential.

This scheme allows for cost optimization: expensive mobile proxies are used only during the critical registration and warming phase (1-2 weeks), while the main work is done through more affordable residential proxies.

Combination for Mass SMM (Instagram, TikTok)

SMM agencies managing dozens of client accounts often use a hybrid scheme:

• Residential Proxies (Provider A) — 60% of Accounts: The main pool of client accounts operates through residential proxies. They provide a balance between trust and cost. Suitable for regular posting, stories, and interaction with followers.
• Mobile Proxies (Provider B) — 30% of Accounts: For VIP clients or accounts with a high risk of blocking (e.g., aggressive mass liking, mass following). Mobile IPs reduce the likelihood of bans during active actions.
• Data Center Proxies (Provider C) — 10% of Accounts: For internal test accounts of the agency, where blocking is not critical. Used for training new employees and testing new strategies.

Combination for Scraping Marketplaces

When scraping Wildberries, Ozon, or Avito, speed and request volume are crucial. Here, a different logic applies:

• Data Center Proxies (Provider A) — 70% of Requests: The main load goes through fast and cheap data center proxies. They allow thousands of requests per minute at minimal costs. Suitable for scraping public data (prices, names, descriptions).
• Residential Proxies (Provider B) — 30% of Requests: For more delicate tasks — scraping reviews, seller data, hidden categories. Marketplaces are stricter with data centers when accessing such data; residential IPs pass through more easily.

An important point: when combining providers, ensure that the IP addresses do not overlap in subnets. If two providers rent IPs from the same data center, diversification loses its meaning — a subnet block will affect both.

Setting Up Balancing in Anti-Detect Browsers

Anti-detect browsers are the main tool for working with multiple proxies. Dolphin Anty, AdsPower, Multilogin, and GoLogin allow you to create separate profiles for each account with individual proxies. Let's look at how to set up load distribution among providers in popular solutions.

Setup in Dolphin Anty

Dolphin Anty is a popular choice among arbitrage specialists due to its convenient profile management and built-in automation. Here’s how to set up work with three providers:

1. Create Profile Groups: In the left menu of Dolphin, create three folders: "Provider A (Main)", "Provider B (Backup)", "Provider C (Tests)". This will simplify visual separation.
2. Add Proxies for Each Provider: Go to the "Proxies" section → "Add Proxy". Paste the list of proxies from the first provider in the format IP:PORT:LOGIN:PASS. Name the group "Provider_A". Repeat for the other providers.
3. Create Profiles Linked to Proxy Groups: When creating a new profile in the "Proxies" section, select "Use from List" → choose the desired group. Dolphin will automatically assign a free proxy from that group.
4. Set Up Rotation: If the provider supports time or request-based rotation, specify this in the proxy settings. For example, for mobile proxies, set rotation every 10 minutes via a special IP change URL.
5. Check Operation: Launch several profiles from different groups and check the IP via the service whoer.net or 2ip.ru. Ensure that each profile uses a proxy from its provider.

The advantage of Dolphin is the ability to perform bulk operations. You can select 20 profiles and reassign them to another proxy group with one click if the main provider is unavailable.

Setup in AdsPower

AdsPower has a similar logic but with more advanced automation features:

1. Import Proxies via CSV: AdsPower allows you to upload hundreds of proxies at once via a CSV file. Create a file with columns: IP, Port, Username, Password, Provider_Name. Import it through the "Proxy Management" section.
2. Use Tags for Labeling: When creating a profile, add a tag with the provider's name (e.g., #ProviderA). This will allow you to quickly filter profiles by proxy source.
3. Set Up Automatic Switching on Errors: AdsPower has a "Fallback Proxy" feature — if the main proxy is unavailable, the profile will automatically switch to the backup. Specify in the profile settings the main proxy (Provider A) and the backup (Provider B).
4. Use API for Dynamic Balancing: AdsPower has a powerful API. You can write a simple script that monitors the availability of providers and automatically redistributes profiles on failures.

Setup in Multilogin and GoLogin

Multilogin and GoLogin operate on a similar principle. In both browsers, you create separate profiles and manually specify proxies for each. For load balancing, it is recommended to use a naming system:

• Name profiles according to the scheme: FB_Account_01_ProvA, FB_Account_02_ProvB. This will quickly clarify which profile uses which provider.
• Create an Excel table with correspondence: profile → proxy → provider → last check date. This will simplify management as the number of accounts grows.
• In GoLogin, use the "Proxy Checker" function for regular checks of all proxies' operability. Non-working proxies are automatically marked in red.

Automating Rotation Between Providers

Manually switching between providers during failures takes time and can lead to downtime. Automating rotation allows the system to independently choose the working provider and switch when problems occur. Let's consider several implementation methods.

Using Proxy Rotators

A proxy rotator is an intermediary service that receives your requests and automatically distributes them among several providers. You connect to one rotator address, and it internally switches between providers according to specified rules.

Popular Solutions:

• Proxy-Cheap Rotator: A free tool that allows you to combine proxies from different providers into a single pool. Configured via a web interface, it generates a single endpoint for connection.
• ProxyMesh: A paid service with advanced balancing logic. Supports prioritization of providers (main → backup → failover), automatic availability checks.
• Custom Rotator on HAProxy: For technically savvy users. HAProxy is a free open-source load balancer. Installed on a VPS, configured via a config file.

Example of Setting Up a Simple Rotator: Suppose you have proxies from three providers. You install Proxy-Cheap Rotator on your computer or VPS, add all proxies with provider tags. You set a rule: "Use Provider A 70% of the time, B 20%, C 10%". The rotator generates a single address like 127.0.0.1:8888. You specify this address in all profiles of the anti-detect browser. The rotator distributes requests among providers according to the specified proportions.

Scripts for Automatic Checking and Switching

If you are working with anti-detect browsers that have an API (AdsPower, Dolphin Anty), you can write a simple monitoring script. The script checks the availability of each provider's proxies every 5-10 minutes and automatically switches profiles to the working provider during failures.

Script Logic:

1. The script stores a list of proxies for each provider.
2. Every 5 minutes, it makes a test request through each provider's proxy (e.g., to google.com).
3. If Provider A does not respond or returns an error, the script marks it as "unavailable".
4. Through the anti-detect browser's API, the script retrieves a list of all profiles using Provider A's proxies.
5. It reassigns these profiles to Provider B's proxies (backup).
6. Sends a notification to Telegram: "Provider A is unavailable, 15 profiles switched to Provider B".
7. Continues monitoring. When Provider A is available again, it switches profiles back.

Such scripts can be ordered from freelancers on Kwork or FL.ru for 2000-5000 rubles. For experienced users, they can be written independently in Python in a couple of hours using the requests library and the browser's API documentation.

Built-in Features of Providers

Some proxy providers offer built-in balancing mechanisms. For example, you buy proxies from two providers, and they provide a single endpoint with automatic rotation between their servers. This is convenient but has a limitation: balancing works only within one provider; it does not switch between different providers.

A more advanced option is to use sticky sessions. The provider gives you one IP address that "sticks" to your session for a certain time (e.g., 10 minutes). This is useful for working with social networks, where frequent IP changes within one session raise suspicions.

Monitoring Quality and Switching on Failures

Distributing load among providers is not a one-time setup but an ongoing process. The quality of proxies can change: today Provider A works great, but in a month, its subnets may get blocked. Regular monitoring allows you to identify problems in time and adjust the distribution.

Metrics to Track

For each provider, track the following indicators:

Maintain a simple Google Sheet where you enter these metrics for each provider weekly. This will allow you to see trends: for example, Provider B has shown an increase in bans over the last two weeks — perhaps its subnets have been blacklisted by Facebook.

Monitoring Tools

To automate monitoring, use specialized services:

• Proxy Checker Pro: A free program for Windows/Mac that checks lists of proxies for operability, speed, and anonymity. Supports bulk checks of up to 1000 proxies at once.
• Whoer.net API: A paid API for checking the trust score of proxies. Can be integrated into your scripts to automatically check the quality of each provider's IP.
• UptimeRobot: An availability monitoring service. Set up checks for the availability of each provider's proxies every 5 minutes. Receive notifications via email or Telegram when unavailable.
• Custom Dashboard in Google Sheets: Create a table with formulas that automatically calculates the percentage of successful/unsuccessful requests for each provider based on the logs of the anti-detect browser.

Switching Scenarios on Problems

Determine in advance under what conditions you will switch the load from one provider to another:

• Scenario 1 — Complete Failure: The provider is unavailable for more than 30 minutes. Action: automatically switch all profiles to the backup provider, notify the support of the main provider.
• Scenario 2 — Increase in Bans: Over the last 3 days, the percentage of account bans through Provider A has risen from 2% to 15%. Action: stop creating new accounts through this provider, switch new accounts to Provider B, test the quality of Provider A's IP.
• Scenario 3 — Decrease in Speed: The average page load time through Provider B has increased from 2 to 8 seconds. Action: reduce the load on this provider from 30% to 10%, redistribute the released load to Providers A and B.
• Scenario 4 — Traffic Limit Exhaustion: Provider's residential proxies have only 5% of the monthly traffic limit left, and there are still 10 days until the end of the month. Action: transfer some tasks to a provider with unlimited traffic (usually data center proxies).

Write these scenarios down as a checklist and follow it when problems arise. This will prevent panic decisions and help preserve accounts.

Cost Optimization When Working with Multiple Providers

Working with multiple proxy providers increases costs, but with the right approach, you can optimize expenses without sacrificing quality. Let's consider cost-saving strategies.

Combining Expensive and Cheap Proxies

Not all tasks require expensive mobile proxies. Use the principle of "the right tool for the right task":

• Mobile Proxies ($80-150/month per IP): Only for critical tasks — registration and warming up new Facebook/Instagram accounts, working with VIP clients in SMM.
• Residential Proxies ($50-100/month per IP or $7-15 per GB): For main work — managing active advertising campaigns, posting on social media, scraping with high trust.
• Data Center Proxies ($1-5/month per IP): For auxiliary tasks — scraping public data, monitoring competitors, test accounts.

Example of Optimization for an Arbitrage Specialist: Instead of using mobile proxies for all 30 accounts ($2400-4500/month), use them only for the first 14 days of warming each account. After warming, switch the account to residential proxies ($50/month). Savings: from $4500 to $1500/month while maintaining quality.

Using Traffic Tariffs vs. Dedicated IPs

Residential proxy providers offer two types of pricing:

• By Traffic: You pay for gigabytes of data used (usually $7-15 per GB). Suitable for tasks with low traffic volume — managing social media, launching ads.
• Dedicated IPs: Fixed price per IP per month ($50-100), unlimited traffic. Suitable for scraping large volumes of data.

Calculate your monthly traffic and choose the optimal option. For an SMM agency managing 40 Instagram accounts (approximately 2-3 GB of traffic per account per month), the traffic tariff is more profitable: 40 accounts × 2.5 GB × $10/GB = $1000/month versus $2000-4000 for 40 dedicated IPs.

Negotiating Discounts with Providers

When working with multiple providers, you become a large client for each of them. Use this to negotiate discounts:

• Request a volume discount: "I plan to use 50 GB/month, what discount can you offer?" Many providers give a 10-20% discount for large package purchases.
• Ask for a trial period: "I am testing several providers, give me 3-5 days free or with a 50% discount to assess quality."
• Pay for several months upfront: usually gives a 10-15% discount.
• Use referral programs: bring in other users and receive bonuses to your balance.

Abandoning Ineffective Providers

Regularly assess the performance of each provider. If one consistently underperforms, consider switching to a more reliable option. This will help maintain the overall quality of your operations and minimize risks.

Conclusion

Distributing load among multiple proxy providers is essential for ensuring stability and minimizing risks in your operations. By implementing the strategies outlined in this guide, you can optimize your workflow, reduce costs, and enhance the overall effectiveness of your proxy usage.
