Residential proxies route traffic through IP addresses assigned by consumer ISPs to real households. Because they look like normal users, they are preferred for:
- Ad verification & brand protection — see ads the way real users do.
- Localization & UX QA — test city or country-level experiences.
- Price and availability monitoring — track SKUs across regions.
- Fraud & abuse research — observe behavior without exposing your own network.
Residential vs Datacenter: Datacenter IPs are cheaper but easy to flag. Residential IPs are harder to detect and carry higher trust.
