Ad verification is the process through which brands ensure that ads are correctly displayed, aligned with their intended placement, and protected from fraud schemes like cloaking or bot-driven impressions. However, verifying ads from a single server or datacenter IP can be easily spotted and blocked. But with residential and mobile IP proxies that mimic real users' browsing behavior, brands can see what a real visitor would.
In this guide, you will get an actionable list of the 5 best proxies for ad verification with a table that breaks down their strength, coverage, and pricing.
Proxies allow brands to test campaigns from the perspective of real users on particular devices, regions, and networks. This helps to safeguard important KPIs that help to keep brands safe, such as cloaking detection, redirect chain visibility, landing page compliance, and geo/device targeting validation.
When it comes to ad verification, each proxy type has its trade-offs, and a choice of the right mix is important for accurate and scalable testing.
Here is a list of the top 5 proxy providers for ad verification. The list was curated after considering geographic diversity, anonymity, speed, reliability, scalability, transparency, and compliance.

Before you select a proxy solution, consider the following factors:
| Proxy Type | Rotation (Short vs Sticky) | Targeting (Geo Depth) |
|---|---|---|
| Residential | Rotating IPs for broad sampling; sticky for ad journeys | Country → city-level targeting; good for retail/CPG audits |
| Mobile (3G/4G/5G) | Frequent rotation mirrors user churn; sticky sessions mimic app sessions | ASN/carrier targeting for in-app & social ads |
| Datacenter | High-volume rotation for scale testing; limited stickiness | Mostly country-level; less reliable for local authenticity |
To run an effective ad verification workflow, here is a structured playbook that would help you keep audits not only credible but consistent.
Common challenges that brands may face while running ad verifications are blocks and CAPTCHA, geo drifts, cost creep, session drops, as well as policy and compliance issues. Platforms can detect automation and block access or even trigger CAPTCHA. In cases like this, you may need to switch to residential or mobile IPs, add rendering equivalents, and rotate more frequently.
Geo drift occurs when the reported location does not match the intended market. When this happens, results may be skewed. A quick fix for this is to tighten targeting to the city level or carrier-specific IPs. Additionally, an IP change may result in a long ad journey break, so it's best to use ISP or static residential proxies during sticky sessions to prevent this.
Other problems that brands may encounter while utilizing proxies in ad verifications are high traffic volumes resulting in higher cost implications, and misalignment with data privacy laws and the provider’s TOS. In the case of the former, implement throttling and sampling cadence. The latter will require you to review terms of service, source IPs ethically, and maintain compliance. Ensure you seek legal counsel whenever in doubt.
Each proxy provider has their unique strengths based on your use case. Live Proxies offers premium reliability and sticky sessions that are up to 60 minutes. Proxies from this provider provide high-quality audits and are best suited for enterprise and use cases where stability is a priority.
Oxylabs, however, is ideal for enterprise-grade scale, while SOAX offers fine city and carrier-level controls, making it suitable for granular geo-targeting. A provider like IPRoyal is best for brands on a strict budget, while ProxyEmpire offers strong multi-geo coverage with both rotation and sticky session options.
The demand for accurate, scalable, and ethically sourced proxies for ad verification continues to grow as ad fraud becomes more sophisticated. While the providers reviewed in this article each have their unique strengths, the best choice depends on your specific use case. To ensure that your verification efforts are effective, prioritize providers that offer high-quality proxy, compliance, and success rates.
