I am running localized advertising campaigns across multiple tier-one countries, but checking how our ads look to actual consumers is super difficult. Whenever we use standard VPNs or mobile proxies combined with browser developer tools, search engines and ad networks still detect our desktop origin or proxy headers, showing altered search layouts. I need a way to see exact ad placements, localized Google Play store rankings, and native mobile feeds as a real local resident would see them. How do you handle true geo verification?
