As someone who works with ad campaigns and landing pages in different regions, one of my biggest headaches was making sure everything looked right across countries. Traditional VPNs were slow and often blocked, while cheap proxies just didn’t hold up for repeated testing.
I switched to residential proxies after reading how they use real user connections instead of datacenter IPs. That alone made a huge difference — no more weird redirects, fewer verification hurdles, and I could see the pages exactly how local users would.
I ended up using Nsocks because they have over 80 million residential IPs in 195+ countries, with the ability to target down to the city or even ISP. It made my quality assurance and ad verification process so much smoother.
Setup was straightforward, and the rotation features meant I didn’t have to keep changing IPs manually. If you’re managing ads, running A/B tests, or doing anything that needs true multi-region views, residential proxies are worth exploring.
