What's the best way to check proxies for reliability and speed? or How do you properly check proxies

If you wanna check proxies fast, try ScraperBox or Smartproxy’s tester.

Pinging is useless if the proxy bans you after one request.

I test with Google—if it loads in under 2 sec, it’s a keeper.

Free tools? Meh. Spys.one is okay for a quick check, but don’t rely on it.
