Why Marseille matters for ad verification
Marseille 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.

The proxy type that fits ad verification best is Residential Proxies, paired with mixed sessions. It balances success rate against cost for this exact use case; you can fall back to datacenter for easy targets, but the hard ones in Marseille, France demand residential-grade trust.

Which proxy type should I use for ad verification?
