Why Lisbon matters for ad verification
The reason Lisbon deserves dedicated attention is simple: fraudsters cloak against known checker IPs, so you must look like a real local user. Layer on its status as an emerging startup and tourism data market, and generic global pools that work elsewhere start returning partial or misleading results for ad verification.
Best proxy type for ad verification
For ad verification, we recommend Residential Proxies as the default in Lisbon, Portugal. 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.

Which proxy type should I use for ad verification?
Confirming ads render correctly and detecting fraud across markets. Residential Proxies are the safest default here because they carry genuine consumer trust, and a mixed session pattern fits this workload. Datacenter IPs work for lenient targets but fail fast on strict ones.
Do I need Lisbon-based IPs specifically?

How much do proxies for ad verification in Lisbon cost?
Residential traffic runs from about $0.80/GB at value networks like Cheapest Proxies up to $6/GB at legacy vendors; datacenter IPs can be under $1 each. Compare on cost per successful request — a cheap pool that fails often is more expensive in the end.
