Working on regional marketing campaigns often means testing landing pages, ad creatives, and offer flows across different countries. At first, I used basic VPNs and public proxies, but they were constantly blocked or too slow to handle multiple requests.

After some research, I switched to residential proxies, and the difference was night and day. With real residential IPs, the traffic looked genuine, avoiding most captchas or bans, and made A/B testing across regions much smoother.

I've been using Nsocks because of their huge pool — 80 million+ residential IPs across 195 countries — and the ability to target by city or ISP. It was easy to integrate into my existing tools, and the stability has been excellent so far.

If you deal with ad verification, price monitoring, or geo-restricted testing, residential proxies are absolutely worth considering. Nsocks has made it a lot easier for me to run global campaigns without worrying about getting blocked.
