What is a Proxy in Arbitrage?

A proxy (proxy server) routes HTTP/HTTPS traffic through an intermediary, replacing the client's visible IP and often GEO. In traffic arbitrage, proxies are infrastructure for landing QA, ad-cabinet access from a target country, and profile isolation in an anti-detect browser—not a mass paid-traffic source.

Proxy types

  • Datacenter — cheap data-center IPs; easily detected, often banned on signup.
  • Residential — home ISP IPs; higher trust, higher cost; used in farming and QA.
  • Mobile — carrier IPs; highest trust, highest price; rarely for bulk.
  • Rotating — IP changes per request or timer for scraping and tests.

Typical media-buyer tasks

Viewing landings and pre-landers as users see them in target GEO; checking tracker redirects; cabinet access under travel restrictions. Proxies do not replace traffic sources—buying runs through ad networks, not proxy pools.

Limits and risks

Meta, Google, and TikTok block datacenter/VPN IPs on account creation. IP GEO vs billing country mismatch is a red flag. Public free proxies leak credentials and fingerprints. Compliance: working from an allowed GEO should be documented for agency clients.
