Ad fraud costs the industry billions annually. Residential proxies let you see ads exactly as a real user does -- verifying placement, creative, and targeting accuracy in every market.
Use rotating residential proxies for ad verification. You need to see what a real local user sees, and residential IPs are the only way to do that accurately. Mobile proxies help verify in-app ad placements.
