look, i'm seeing numbers all over the place. for my affiliate stuff, i need to test offers from different countries, you know. i'm curious about the actual data on using a vpn vs a residential proxy for this. like, if i need to see a german netflix library once, a vpn is fine. but if i'm running automated geo-tests on an ad campaign across 20 locations daily, i'm thinking proxies might be more stable. my vpn connection sometimes just drops and the ip changes, which ruins the data. ahrefs and semrush are great for competitors, but utterly useless for tracking this kind of stuff, lmao. so, genuinely want to know. what's the ctr difference on localized offers when using a proxy pool vs a vpn's rotating ips? anyone have hard numbers on this, or am i just going to have to run my own month-long test? citation needed.
