Decodo (Smartproxy) offers the best overall value for most ad verification teams, with a 115M+ IP pool, a 99.92% success rate, and city/ZIP/ASN targeting for location-accurate checks. Teams that need screenshots, timestamps, and full landing-page evidence in a single workflow should consider Scrapeless, which pairs proxy routing with a managed cloud browser.
Large, multi-market verification programs get the deepest control and compliance from Bright Data or Oxylabs, while VoidMob’s real carrier IPs are the strongest option specifically for catching mobile-app cloaking and ad fraud.
Ad verification exists because advertisers can’t trust that the creative, landing page, or placement a publisher reports is what’s actually being served. Malicious or non-compliant ad networks use cloaking techniques that detect known verification-company IPs — datacenter ranges especially — and quietly serve a “clean” version of the ad or redirect chain to anyone who looks like a bot or auditor.
Real users on real residential and mobile connections keep seeing the actual creative, malware redirect, or non-compliant landing page. That’s why verification and compliance teams rely on residential and mobile proxies with precise geo-targeting to see ads the way an actual person in a specific city or on a specific carrier would.
Below is a comparison of seven proxy providers used for ad verification, followed by a breakdown of which proxy type fits which verification scenario.

Provider Breakdowns
Decodo (Smartproxy) — Best Value for Most Teams
Decodo pairs a 115M+ IP pool with a measured 99.92% success rate and 0.53-second response time, backed by country, city, ZIP, and ASN targeting. Its pool is ethically sourced, which matters for verification vendors that need to stand behind their own data collection methods. For teams that need reliable, location-accurate checks across residential, mobile, and ISP proxy types without paying enterprise pricing, it’s the strongest general-purpose starting point.
Scrapeless — Best for Rendered Evidence Workflows
Scrapeless goes beyond raw proxy access by bundling proxy routing with a managed cloud browser, which captures screenshots, timestamps, and landing-URL chains as part of the same workflow. That matters for verification use cases where the deliverable isn’t just “was the ad there” but documented, timestamped evidence of what was actually served. A $5 free credit and pay-as-you-go pricing make it easy to test against a specific campaign before committing to volume.
Bright Data — Best for Enterprise-Scale Programs
Bright Data’s 400M+ IP pool spans residential, mobile, ISP, and datacenter types, with the broadest control surface in this comparison — targeting down to exact coordinates, not just city or ZIP. SOC 2 and SOC 3 compliance make it a fit for large verification teams operating under strict vendor and data-handling requirements. At $4/GB pay-as-you-go, it’s priced for scale rather than occasional spot checks.
Oxylabs — Best for Enterprise Network Operations
Oxylabs posts a 99.93% success rate — the highest tested rate in this comparison — across a 175M+ IP pool with country, state, city, ZIP, and ASN targeting. SLA-backed reliability suits high-volume, multi-market verification operations where consistent uptime matters as much as raw coverage. Entry pricing around $6/GB positions it toward larger teams running verification at meaningful scale rather than light spot-checking.
SOAX — Best for Granular Targeting Programs
SOAX’s 155M+ IP pool and stable sessions come with a 99.78% success rate and flexible filtering aimed at narrow, specific markets — useful when a verification program needs to confirm delivery in a particular city or ASN rather than just a country. At $3.60/GB entry pricing, it sits between budget and enterprise tiers, offering granular control without Bright Data or Oxylabs’ full enterprise pricing.
IPRoyal — Best for Smaller Deployments
IPRoyal covers residential, mobile, and ISP proxies with country and city-level targeting and non-expiring traffic, making it a workable option for smaller verification deployments or teams checking a limited set of campaigns rather than running continuous, large-scale monitoring. At $7/GB entry pricing it isn’t the cheapest per-GB option here, but the lack of expiring traffic suits lighter, irregular verification workloads.
VoidMob — Best for Mobile-First Verification (Anti-Cloaking)
VoidMob is built specifically around real carrier IPs rather than a general-purpose proxy pool, which gives it the lowest detection risk in this comparison for mobile-specific use cases. That matters because cloaking schemes targeting mobile app inventory are often built to detect and evade generic proxy traffic, while genuine 4G/5G carrier IPs see the same creative a real mobile user would. It’s positioned as a specialist tool — accessed via API or MCP with custom pricing — for catching cloaked creatives and mobile ad fraud that other proxy types can miss.
How to Choose a Proxy for Ad Verification
Match proxy type to the inventory being verified.
Desktop and web campaigns are well served by residential proxies, which mimic real user traffic at a reasonable cost. Mobile app inventory and carrier-sensitive delivery need real mobile (4G/5G) IPs, since cloaking systems targeting mobile ads are often specifically built to detect and serve a clean version to non-carrier traffic.
Avoid datacenter proxies for production verification.
Datacenter IPs are cheap but carry the highest detection risk and the poorest geo-accuracy of any proxy type — ad networks running cloaking schemes frequently recognize known datacenter ranges and serve a compliant “clean” version specifically to that traffic, which defeats the purpose of verification entirely. Reserve datacenter proxies for basic diagnostics, not compliance or fraud checks.
Prioritize measured success rate over pool size alone.
A larger IP pool doesn’t guarantee reliable results if a meaningful share of requests fail or time out. Providers that publish tested success rates (Decodo, Oxylabs, SOAX) give a clearer signal of real-world reliability than raw pool size.
Decide whether you need evidence capture, not just proxy access.
If the deliverable is documented proof — screenshots, timestamps, full redirect chains — a provider that bundles proxy routing with a managed browser (Scrapeless) saves building that capture layer yourself. If you already have your own capture pipeline, raw proxy access from any provider in this comparison is sufficient.
Weigh geo-targeting granularity against what you’re verifying.
Confirming national ad delivery only needs country-level targeting. Confirming that a specific city, ZIP code, or carrier is receiving the correct creative requires providers with that level of precision (Bright Data, Oxylabs, SOAX, VoidMob for carrier-level).
Consider compliance and sourcing for regulated or brand-safety-sensitive programs.
Verification vendors reporting to advertisers or operating under strict data-handling agreements should weigh certifications like SOC 2/3 and documented, ethical IP sourcing alongside raw performance and price.
