I was reviewing advertising campaigns for a freelance client and noticed that the banners and sponsored posts I saw from my side looked completely different from the screenshots people in the United States were sending me. My friend recommended America proxy https://spaceproxy.net/en/proxy-usa/ because he already uses it for checking how US-targeted ads actually appear in different regions. I decided to test it during a long campaign review session and immediately noticed how much more accurate the previews became. I could finally see the same placements, recommendations, and ad formats American users normally experience. That helped me identify several targeting problems much faster than before. It also made my reporting feel way more professional and detailed.
