Define the campaign question
Specify market, device class, landing URL, expected creative or advertiser, and the time window before opening a browser.
Campaign evidence workflow
Ad verification proxies for repeatable, location-aware campaign QA
Observe public ad delivery from the intended market, preserve the route and timestamp, and separate network evidence from creative, consent, account, and auction effects.

What a controlled proxy route changes—and what it does not
Treat the proxy as one measured input in the verification method, not as proof that an ad must appear.
Feature
✕Uncontrolled observer
✓Controlled geo session
Record the requested market
Often implicit
✓Country or region requested
Repeat a check with a bounded session
Route may drift
✓Sticky when continuity is needed
Separate route failure from ad absence
Hard to diagnose
✓Status and route recorded
Guarantee a specific ad impression
Auction-dependent
Still auction-dependent
Create an auditable observation
Missing context
✓Time, locale, route, artifact
A defensible ad verification run
Use the same sequence for spot checks and scheduled monitoring so missing creatives and blocked requests are classified consistently.
Create an isolated session
Match proxy geography, browser locale, timezone, and a clean cookie profile. Use a short sticky session only for a multi-page path.
Capture the public observation
Record response status, redirect chain, visible creative, destination domain, timestamp, and a screenshot when permitted.
Classify the result
Distinguish ad not served, consent wall, account targeting, geo mismatch, target error, and proxy authentication failure.
Store evidence and retry reason
Keep a compact redacted artifact and stop repeated checks when the result is policy- or account-dependent.
Frequently asked questions
Can a residential proxy guarantee that a specific ad appears?+
No. Ad auctions, audience rules, frequency caps, consent state, inventory, account history, and timing still affect delivery. A proxy controls the network location used for the observation.
Should every verification request rotate IPs?+
Use rotation for independent observations. Use a short sticky session when one verification path spans a landing page, redirect, and follow-up request that must keep the same network identity.
What evidence should be stored?+
Store the requested market, observed exit, timestamp, response status, destination URL, a redacted screenshot or HTML marker, and the reason for any retry. Avoid retaining personal account data.
Is logged-in ad verification supported?+
Prefer public or authorized test accounts. Logged-in checks add account risk and privacy obligations, so access, retention, and automation rules should be reviewed separately.
