Newcomers in traffic arbitrage often buy one package of proxies and try to use it for everything: for the tracker, for ad accounts, for warming up accounts. The result is broken connections, banned Facebook Ads or TikTok Ads accounts, and unclear statistics in Keitaro. The reason is simple: proxies for trackers and proxies for buyers serve different purposes, and their requirements are fundamentally different.
Why These Are Two Different Purchases
In traffic arbitrage, there are two completely different technical contours. The first is the tracker (Keitaro, Binom, RedTrack), which is hosted on a server and receives clicks from ads, decides where to redirect the user, and collects conversion statistics. The second contour is the buyer's workspace: the browser (often an anti-detect type like Dolphin Anty, AdsPower, Multilogin, or Octo Browser) through which they access Facebook Ads, TikTok Ads, or Google Ads accounts, create accounts, and launch campaigns.
The tracker’s task is to quickly and reliably process the flow of clicks without getting caught by ad platform blocks and anti-fraud systems at the redirect level. The buyer’s task is to appear as similar as possible to a regular live user from a specific region so that the ad account does not trigger an account block. These are fundamentally different load profiles, with different requirements for geo, speed, type of IP, and even how many requests per second the proxy must handle.
If the same pool of proxies is used for both tasks, a conflict arises: a proxy that is good for the high load of a tracker (data center, fast) looks suspicious in the ad account as a data center IP rather than a home user. Conversely, a residential proxy, ideal for warming up an account, may be too slow and unstable for processing hundreds of clicks per minute on the tracker server.
What Is a Proxy for a Tracker
A proxy for a tracker is mainly needed in two scenarios. The first is when the tracker itself is not hosted on a dedicated server with its own IP, but operates through a proxy to mask the hosting address (so that the ad platform does not see that the click is coming from a data center server). The second is when it is necessary to check how the landing page or offer looks from the perspective of different geos, that is, to test redirects and cloaking from a specific country.
Key requirements for such a proxy are stability and speed. The tracker must process clicks almost instantly: if the delay at the redirect level is seconds, the user will simply close the page, and the ad platform will record low traffic quality. Therefore, for most tracking tasks, data center proxies are well-suited — they are fast, stable, and cheaper, which is important with large volumes of clicks.
An important point: for the tracker, the "naturalness" of the IP is not critical in the same way it is for the ad account. Facebook or TikTok anti-fraud systems do not see the IP of the tracker — they only see the IP of the end user who clicked on the ad. Therefore, a data center proxy for tracking and checking offers is an absolutely viable and economically justified option.
What Is a Proxy for a Buyer
A proxy for a buyer is a completely different story. Here, the IP address is directly linked to the account in the ad account, and it is based on this that the anti-fraud systems of Facebook Ads, TikTok Ads, Google Ads, and other platforms determine whether it is a real user or suspicious activity. If the buyer logs in with a data center IP, the system almost immediately sees the discrepancy: regular users do not browse the internet through a hosting provider's IP.
Therefore, to work with ad accounts, arbitrageurs use residential proxies — these are IP addresses from real home connections issued by internet providers to ordinary people. Such an IP appears natural to the ad platform, even if it is behind a proxy server.
For a number of verticals, especially when farming TikTok Ads accounts or working with mobile traffic, arbitrageurs go further and use mobile proxies — IP addresses from real mobile network operators. Such proxies are less likely to raise suspicion because mobile networks often use NAT, and one IP can indeed belong to thousands of real subscribers simultaneously — this is normal behavior that the system does not consider anomalous.
For the buyer, another critical factor is that the geo of the proxy must exactly match the geo targeting of the campaign. If the campaign is set for Germany, and the account's IP is identified as being in another country, this is an immediate red flag for the ad account's security system.
Comparison Table: Tracker vs Buyer
| Parameter | Proxy for Tracker | Proxy for Buyer |
|---|---|---|
| Main Task | Processing clicks, redirects, cloaking offers | Accessing the ad account, farming and managing accounts |
| Type of IP | Data Center | Residential or Mobile |
| Priority | Speed and stability under load | Naturalness and trust of anti-fraud systems |
| Geo Sensitivity | Needed for checking cloaking by countries | Critical, must match targeting |
| Traffic Volume | High, thousands of clicks per day | Low per account, but many parallel sessions |
| IP Binding to Session | Not critical, can change frequently | Needs a static IP for the entire account's lifespan |
| Cost | Lower due to data center | Higher, but pays off by preserving accounts |
Typical Mistakes of Arbitrageurs
The most common mistake is saving on proxies for buyers. An arbitrageur buys a cheap data center package, sets it up in both the tracker and the anti-detect browser for the ad account. For the first few days, everything works, but after several campaign launches in Facebook Ads, the account gets banned — the system recognized the data center IP as inconsistent with the "regular user" profile.
The second mistake is using the same residential or mobile IP simultaneously for dozens of accounts in the anti-detect browser. Even a quality residential proxy starts to look suspicious if 20 different Facebook Ads profiles suddenly log in from it consecutively. Advertising platforms analyze not only the type of IP but also the behavior patterns on it.
The third mistake is frequently changing the IP of the buyer's account. If a residential proxy rotates every few minutes, and the account is set for a static IP, the system sees the user's "jumps" between cities and even countries within minutes — this is a classic sign of fraud, leading to a ban or restriction of the ad account.
The fourth mistake is ignoring the load on the tracker proxy. If thousands of clicks per day are attempted to be processed through a cheap residential IP with limited speed, the tracker starts to "choke," the percentage of users not reaching the offer increases, EPC drops, and ultimately the connection seems unprofitable, although the problem was purely with the proxy.
How to Choose a Proxy for a Tracker
For a tracker, the top priority is response speed and stability under load. When choosing, look at the response time of the proxy (the lower, the better for redirect speed), the percentage of successful connections without interruptions, and the ability to handle a large number of simultaneous connections if you have several active campaigns.
For most tracking and cloaking tasks, data center proxies are sufficient — they provide high speed at a reasonable price and easily scale with increasing traffic volume. For checking cloaking in specific geos, it is important that the proxy provider has a wide selection of countries and cities so you can accurately simulate the location of the target audience for the campaign.
If your tracker processes traffic from sensitive verticals where anti-fraud systems of ad networks sometimes check the redirect server itself, it is worth considering residential proxies even for the server part — but in most cases, data center proxies are quite sufficient and significantly cheaper at high volumes.
How to Choose a Proxy for a Buyer
For a buyer, the main rule is one static IP per account, and this IP must match the geo targeting of the campaign as closely as possible. When choosing proxies for ad accounts, pay attention to the ability to assign a specific IP to the account for a long time (sticky session), rather than a random IP from the pool with each connection.
For Facebook Ads and Google Ads, residential proxies are more commonly used — they provide a balance between the naturalness of the IP and affordable pricing when working with dozens of accounts. For TikTok Ads and verticals where maximum "liveliness" of traffic is important, many arbitrageurs switch to mobile proxies because TikTok pays particular attention to analyzing mobile behavior patterns.
Be sure to check that the proxy provider offers the countries you need and, ideally, cities — major advertising platforms can verify IP not only by country but also by region, comparing it with billing card data or the device's interface language.
Practical Setup: Keitaro + Anti-Detect Browser
In practice, the setup looks like this: the Keitaro or Binom tracker is installed on a VPS, and if necessary, a data center proxy is connected to mask the server's IP — this is configured at the server configuration level or through a proxy wrapper before the tracker. This setup does not require coding; it is enough to specify the address and port of the proxy in the hosting panel or in the server network settings.
For the buyer, the setup occurs within the anti-detect browser. In Dolphin Anty, AdsPower, Multilogin, or Octo Browser, for each profile, the proxy is specified separately: open the creation or editing of the profile → "Proxy" tab → choose the type (HTTP, SOCKS5) → insert the login, password, IP, and port of the residential or mobile proxy → save and check the IP through the browser's built-in checker.
It is important to assign to each profile exactly the proxy with which the account was registered and warmed up — changing the IP of an already working account is extremely risky. If you need to manage 20-30 client accounts or your own ad accounts, it is more convenient to purchase a pool of static residential IPs with geo binding upfront and distribute them across profiles in the anti-detect browser at the start, rather than changing them on the fly.
Checklist Before Buying Proxies
- Determine what exactly the proxy is needed for: tracker server or access to the ad account
- For the tracker — check response speed and limit of simultaneous connections
- For the buyer — ensure that static IPs are available with long-term binding
- Match the geo of the proxy with the geo targeting of the ad campaign, including the city if it is important for the platform
- For TikTok Ads and mobile verticals, consider mobile proxies separately from residential ones
- Do not use the same IP simultaneously for multiple accounts in the anti-detect browser
- For large volumes of clicks in the tracker, calculate the cost of data center proxies separately from the budget for residential buyer IPs
Conclusion
Proxies for trackers and proxies for buyers serve different purposes and therefore require different characteristics: speed and stability versus naturalness and trust of anti-fraud systems. Attempting to cover both needs with one cheap pool of proxies almost always leads to either losing accounts in ad accounts or losing statistics and money due to a slow tracker.
For the server part and processing large volumes of clicks, it is reasonable to use data center proxies — they are fast and cost-effective when scaling. For managing ad accounts in Facebook Ads, Google Ads, and Instagram, residential proxies are better suited, while for TikTok Ads and mobile verticals, it is worth considering mobile proxies — they provide maximum naturalness of traffic and reduce the risk of account blocks.
