Verify how your ads really look to a genuine user in the target country and city, not from your own office IP but from our residential, mobile and ISP proxy pools — and catch click fraud and affiliate compliance breaches where they happen.
A fixed, corporate-looking IP for a repeatable audit vantage point.
Cost-first IPs for high-volume competitor sweep runs.
Genuine home-user IPs for desktop and web ad audits.
Real 4G/5G carrier lines for in-app ad audits.
Low-ping static IPs to audit in-game and esports ad placements.
Depending on your geo-targeting rules, ad networks serve a different creative, price or offer to users in different countries and even different cities. From your own office IP you never see that difference at all; with a real IP from the target location you check whether the ad is actually running the way it is supposed to look.
Check for yourself, rather than trusting reports alone, that an ad appeared on the agreed publisher, in the right page category and on the right device type. Repeated audits from different locations and device profiles catch placement breaches early.
Abnormally dense clicks from the same IP or the same datacenter block burn campaign budget on traffic that was never real. Monitor how your ad renders across a residential and mobile IP pool to tell genuine engagement apart from suspicious click behavior on the publisher side.
Connect like a real user from the region in question to verify that affiliate partners and publishers are honoring the geography, device and traffic-source rules set out in their contract. Redirects that break the rules, along with blacklisted or grey-listed traffic, come to light this way.
In-app mobile ads usually behave differently from desktop, and some networks serve dedicated creatives only to genuine mobile carrier IPs. With a 4G/5G mobile proxy you audit in-app inventory as though you were on a real user device.
If an ad network or a competitor spots that your audit traffic comes from your corporate IP range, it can serve you a tailored, sanitized ad experience. Because that traffic exits through a wide residential and mobile pool, you look like an ordinary consumer instead.
Instead of a one-off check, an audit repeated at regular intervals from the same city and device profile shows, with timestamps, exactly when a creative changed or when a placement breach began.
Compare impression and click data gathered across different countries and cities to reveal where the ad is working as expected and where the numbers look anomalous.
Ad verification is the process of independently checking whether an ad is genuinely being served as planned in the targeted country, city, device and publisher. The aim is not to take the ad network's own report at face value, but to observe directly what a real user sees.
Why You Need a Proxy: Ad networks and publishers can recognize corporate IP ranges, datacenter IPs and known audit tools, then serve those sources a different (usually sanitized) version. Without a genuine residential or mobile IP from the target location, the ad you see can differ from the one an ordinary consumer sees, and click fraud and affiliate breaches slip past unnoticed.
Which Proxy, and When: For a one-off sweep across a large number of locations, Rotating Proxy is ideal; when you need to follow a campaign session or a user journey end to end under a single identity, Sticky Proxy holds the IP steady for a while. The table below lays out which source IP type fits which audit:
| Proxy Type | When To Use It | Why |
|---|---|---|
| Residential proxy | Desktop and web ad audits | A genuine home-user IP the ad network can't tell apart from an ordinary consumer |
| Mobile proxy | In-app mobile ad audits | Some networks show in-app creatives only to real mobile carrier IPs |
| ISP proxy | A fixed, repeatable audit vantage point | A stable, corporate-looking IP that keeps the same identity across sessions |
The Proxynet pool unifies more than 160 million residential and mobile IPs across 194 countries in a single dashboard. Route your audit traffic over HTTPS Proxy or SOCKS5 Proxy and reuse the same infrastructure for your brand and content monitoring work.
The most basic scenario: you told the ad network to show your ad in Istanbul, but is it actually appearing there, or did the publisher shift the budget to a different city? Agencies verify this by browsing from a real IP in the target city and seeing the ad themselves, rather than trusting their own report — that's how the gap between the report and reality shows up.
"Cloaking" is another common trick: a site shows a clean page to verification bots and search engines while serving something completely different — sometimes policy-violating — to the actual user who clicked the ad. The only way to catch this is browsing from a residential IP that looks like an ordinary consumer; the site already behaves differently toward corporate or known datacenter IPs.
The same logic applies to competitor analysis: to see which cities and hours a competitor is advertising in, you scan from different locations, which gives you a concrete read on where they're concentrating budget and which markets they're prioritizing — similar to market research.
The four stages of setting up an ad audit workflow from scratch:
From programmatic display audits and affiliate compliance to in-app mobile ads and search ad verification — the fields ad verification powers.
Confirm that your display and video ads run with the planned creative in the target country, city and device, using audits repeated from IPs in different locations.
Connect over a genuine 4G/5G carrier line to check that in-app ad inventory, and the mobile-only creatives that behave differently from desktop, are being served correctly.
Verify that affiliate partners are honoring the geography, device and traffic-source rules in their contract by connecting like a real user from that region.
Independently check that in-feed and story ads show the right creative and the right offer for each audience, country and device type.
Test from a genuine search IP that your search ads appear in the expected position, with the right extensions and the right offer, in the target country and city.
Cross-check from regional IPs that the price and promotion promised in an ad match the real price in the target market.

When you take the quality of the proxies they sell together with pre-sales and after-sales support, I can say they are among the best on the market. I want to work with them for a long time — thank you.

I was using a proxy from another company and could not get support. I was already registered on proxynet.io before buying; when a customer-service email arrived on Saturday I decided to try. So far I can say their fast replies and problem-solving approach really impressed me.Read on Trustpilot

Technical support is fast. I was very happy with the ISP proxies; you could make prices a bit more affordable, mobile is unfortunately expensive, but ISP speeds and subnet quality are solid.Read on Trustpilot

City, ASN and carrier targeting on the Residential, ISP, Datacenter and Mobile plans. These are the deepest pools; each country has its own page with its ISPs, carriers and coverage.

Ad verification is the process of independently checking whether an ad is genuinely being shown as planned — right creative, right price, right placement — in the targeted country, city, device and publisher. Instead of trusting the ad network's own dashboard report, you connect like a real user from the target location and observe the outcome yourself.
Ad networks and publishers can recognize corporate IP ranges, datacenter blocks and known audit tools, and may serve those sources a different, usually sanitized version. Your office IP also represents a single city and country, while the campaign you need to audit may be live in dozens of different markets.
For auditing desktop and mobile web ads, residential proxies give the most realistic result because the traffic comes from a genuine home line. For in-app ad inventory you need a real 4G/5G mobile carrier line, because some networks show in-app creatives only to mobile carrier IPs.
Monitor how your ad renders from a wide residential and mobile IP pool, close to the conditions real users in each region would see, then compare that clean observation against the raw click data coming from the publisher. Abnormally dense clicks from the same IP block within the same time window are usually a sign of fake traffic; the proxy gives you the realistic reference point that makes the comparison possible.
Connect like a real user from the region using a proxy that matches the country, city and traffic-source limits set out in your affiliate agreement, then watch the redirect chain and the final page. Traffic routed in from unauthorized geographies, unlicensed use of brand keywords and blacklisted or grey-listed traffic all surface this way.
If you need to follow a user journey end to end under one identity (ad click → landing page → conversion), a sticky proxy holds the IP steady for a while. For impression and creative checks where you want to sweep a large number of locations quickly one by one, a rotating proxy that changes IP on every request is more efficient.
