Residential Proxy Access for Ad Verification

Compare ad placements and redirects from selected residential locations. Combine these observations with publisher, campaign, and fraud-analysis data to investigate differences in delivery.

Residential Network Observations

Review ad delivery through an available residential location. Browser settings, cookies, account state, and the destination's targeting rules can affect the ads returned.

Campaign Quality Checks

Compare ad delivery from selected residential locations and use the observations alongside your existing fraud and campaign-quality signals.

Geotargeting Precision

Select a country and, where inventory supports it, narrow by state, city, ZIP code, and ASN in the Residential Data dashboard to review localized campaigns.

Campaign Verification Reinvented

Use a residential network perspective to review display and search placements from selected locations. Results remain subject to live inventory, routing, and each destination platform's policies.

COMMON QUESTIONS

Ad Tech FAQ

Why is it important to use residential IPs for ad verification?

Residential endpoints add network and location context to an authorized audit. They do not guarantee a specific consumer view or access, so compare observations with your campaign and publisher data.

Can I use PreProx to detect ad fraud?

PreProx provides proxy access for external verification tools. Comparing redirects and placements across available locations can support an investigation, but detecting or proving fraud requires additional campaign and publisher evidence.

Does PreProx work with modern ad managers?

Tools that accept authenticated HTTP or SOCKS5 proxies may support PreProx connection details. Check the tool's supported protocol and authentication settings, then test a small authorized request before using it in your workflow.
