Check Regional Ad Placements Without Spending a Dollar

Ad verification often starts with a simple question: does this ad actually appear in a given market? The free proxy list covers HTTP, HTTPS, and SOCKS5 proxies across 100+ countries, giving you real geo-distributed exit points to spot-check creatives, landing pages, and targeting rules before committing to a paid setup. Because the list refreshes every 30 seconds, you always have a current pool to pull from via the API or a downloaded TXT, CSV, or JSON file. This makes it practical for one-off regional checks or early-stage fraud triage where absolute uptime is not yet critical.

Understand the Limits Before You Rely on Free Proxies

Free proxies are best-effort: speeds and availability vary, and there is no uptime guarantee, so they are not suited to continuous, automated ad monitoring at scale. For ad verification tasks that require consistent residential IPs that mirror genuine user traffic, the paid Residential plan starts at $0.16/GB and carries 99.9% uptime with dedicated support. A practical approach is to use the free list for exploratory checks and preliminary fraud detection, then route high-priority or scheduled verification jobs through residential proxies to avoid false negatives caused by proxy downtime or blocks.

Integrate the Free List Into Your Verification Toolchain

The proxy list is accessible via API, which means you can programmatically rotate endpoints inside your existing ad-verification scripts without manual downloads. Filtering by protocol lets you match HTTP or SOCKS5 to whatever tool you are running, whether that is a headless browser, a custom scraper, or a third-party verification platform. When you find that a specific country or city requires a stable residential IP to replicate authentic user context accurately, the upgrade path to paid residential proxies is direct and uses the same integration pattern, minimising retooling time.
