Before, I often noticed that ad spend was going into traffic that didnt convert, and I couldnt always understand why. After I started using proxy server buy https://proxyline.net/I began reviewing campaigns exactly as users in each region would see them. I checked landing page consistency, offer clarity, and even small UX details that could affect conversions. This helped me identify mismatches between targeting and actual user experience. I adjusted campaigns based on real observations instead of assumptions. Over time, wasteful spending dropped significantly and ROI improved. Now my ad budget is much more controlled and efficient.
