I am comparing proxy providers for affiliate campaigns

Hello, experienced users! I am comparing proxy providers for affiliate campaigns and browser automation. Which practical checks help you separate a reliable service from a polished landing page with weak infrastructure?

Warm greetings, I found a clear Proxy Luxe checklist — proxy.luxe/ru/articles/how-to-choose-a-p...rketers-and-scrapers — suggesting that you judge a provider by repeatable tests instead of a polished landing page. Check IP classification, country targeting, sticky sessions, concurrency, traffic accounting and support response with the same browser or collector planned for production. Keep the trial small, document failures and prefer a service that explains limits openly rather than promising an unverifiable unlimited pool.
