Why Madrid matters for ad verification
Madrid brings its own quirks. Sites there personalise pricing, stock and even page layout by visitor origin, so a request from a foreign datacenter IP describes a market that doesn't really exist. Only in-country addresses reveal what a genuine local user sees — which is exactly why ad verification needs local exits here.
Best proxy type for ad verification
For ad verification, we recommend Residential Proxies as the default in Madrid, Spain. They give you the trust profile this workload needs, and a mixed session strategy suits how ad verification traffic behaves. Datacenter IPs are cheaper but get flagged faster on the strict targets ad verification usually involves.
