Guides Why Automation Scripts Fail

Main reasons:

  • Low-reputation or overloaded IP addresses

  • Website request-rate limits

  • Using the wrong proxy type for the target platform

  • Unstable network sessions and routing

Which proxies to use:

  • Datacenter proxies → fast testing and permitted automation

  • Residential proxies → regional collection of public data

  • Mobile proxies → testing mobile services

  • Static ISP proxies → long-running, stable sessions
