In ad work, people often buy proxies and an antidetect browser together. But don't start with a pile of tools. Start with rules and infrastructure hygiene. In Russian-speaking markets this work is called "arbitrage" (traffic arbitrage): buying ad traffic and sending it to offers for profit, which English speakers know as media buying or affiliate marketing. A good setup gives you a stable working environment, clear payment, compatibility and control over risk.
To choose proxies, start with the general ranking. Then compare residential and static proxies and, if needed, antidetect browsers.
Separate the task from the tool first
Before you buy, answer these questions:
- which ad accounts or work profiles you use;
- in which countries you need to check;
- whether you need a stable IP or rotation;
- which antidetect browser is already chosen;
- how many people will work with the infrastructure;
- what budget you have for the test.
Without these answers, it is easy to buy expensive proxies that don't fit your browser, your geography or your team's process.
When to choose residential proxies
Residential proxies can help if you need flexible geography, a wide IP pool or a traffic-based model. But they require careful tracking of usage and a check of rotation terms.
Before paying, check the countries, the price per traffic, the session length, protocol support, authorization and whether there is a test package. If the task needs one stable IP, a residential option may be overkill.
When static proxies are enough
Static proxies are often more convenient for stable work profiles, tests, QA and cases where a predictable IP rental matters. They are easier to track: you have a price, a term, an IP, authorization and a clear replacement.
If you don't need a wide pool or a mobile network profile, start with static proxies and compare the result with residential on a small pilot.
Compatibility with the antidetect browser
The proxy has to work properly in your chosen browser: authorization, protocol, import format, session stability and a clear way to replace an IP. If you have already chosen an antidetect browser, check its requirements before you buy proxies.
You can compare browsers in the antidetect section, and see how to put the setup together in the guide to antidetect browsers and proxies.
What to check before paying
A checklist:
- the proxy type matches the task;
- the country and region are available;
- the price is clear before payment;
- there is a test or a small package;
- authorization works with your browser;
- support answers a specific question;
- the IP replacement terms are clear;
- there is a backup provider;
- the team understands the platform rules.
For a first shortlist, use RS Score for proxies, but don't treat it as a guarantee of results.
How to run a pilot
A pilot should be short and safe: one proxy type, one browser, one country, a small budget and a clear success criterion. Check proxy import, session stability, support, costs and how easy it is to replace an IP.
Don't scale the setup until you understand the real costs and weak spots. If a provider answers badly at the start, the problem usually gets more expensive as load grows.
How to keep an infrastructure map
For a team, it helps to keep one table: proxy provider, IP type, country, plan, payment date, antidetect browser, owner, work scenario, problems and the date of the next check. This is not bureaucracy. It is a way not to lose track of what was bought where and why.
Also note which profiles and tasks depend on a specific provider. If a service becomes unstable, you will see faster what to move first and which backup is already tested.
When not to buy
Don't buy proxies if:
- the plan terms are unclear;
- the provider promises the impossible;
- support gives canned replies;
- there is no test and the minimum package is large;
- the task breaks platform rules or the law;
- the team doesn't know who is responsible for payment, access and renewals.
Mistakes in the proxy and browser chain
The first mistake is buying proxies without checking the import format in the antidetect browser. The second is choosing a country with no link to the real task. The third is keeping all profiles on one provider with no backup. The fourth is not tracking renewals and losing access at a key moment.
It is better to build a small but clear setup: a main provider, a backup provider, payment rules, a list of owners and a checklist before scaling. That looks simpler than a chaotic purchase of several services, and it is usually cheaper to maintain.
When to review the setup
Review your infrastructure when countries change, the team grows, a new antidetect browser appears, a provider changes its plans or support gets slower. You don't need to rebuild everything all the time, but a working setup should have a review date.
If the project grows, split the tasks: stable profiles, test profiles, backup proxies, payments and notes on support. This order lowers the risk of sudden downtime and shows which services are really worth their money.
