The Best Proxies for Ad Verification in 2026

How Does Ad Verification Work?

Digital ads often get misplaced, either deliberately or accidentally. Where do they end up? After scammers tamper with them, the ads are placed on lewd, untrustworthy websites, where they’re seen mostly by bots.

Ad verification is a process that aims to correct both accidentally and intentionally misplaced ads. During this process, the ad verification specialists check if the ad is displayed according to the advertiser’s criteria, such as location preference. They also make sure that the ad is placed on the right website and is seen by real people.

Proxies are closely tied to this process. Let’s see how.

How Proxies Assist with Ad Verification

Scammers often are familiar with ad verification companies and blacklist their IP addresses. They also have strict anti-botting measures on their websites to filter out all the scrapers. That’s where proxies come in. They allow changing the IP address and looking like a regular user to let the script do its job.

Ad verification specialists use proxies to check ad redirection paths. Scammers frequently steal clicks from legitimate ads by redirecting the user to their websites. Fraudsters do this to lure unsuspecting users to their products or services. Sometimes they even try to install malware on the user’s device.

The third use case is checking how an ad appears in a localized context. This is particularly important for global ad verification companies that need to confirm how ads appear in hundreds of markets simultaneously.

If you place geographic restrictions on an ad, such as targeting users near your physical store, you need to make sure that fraudsters aren’t taking advantage of it. They can find ways to feed advertisers fake location data to get higher prices for their ad impressions. Imagine how much money you’d waste if your ad appeared to users somewhere in Asia instead of the US? Proxies allow you to connect from various locations to see how people worldwide can view the ad.

How to Choose Proxies for Ad Verification

It’s hard to imagine a successful ad verification process without proxies. That’s why you need to make sure you have suitable proxies for the job. Here are a few things to consider when choosing a provider:

First of all, make sure you’re using residential proxies. Any other kind of proxies may get you banned before you get any job done. Meanwhile, residential proxies provide anonymity and make you look like a regular internet user. That way, owners of fraudulent sites won’t be able to know that you’re using proxies and won’t prevent you from running an ad verification script.
The second criteria is a wide range of IP locations because you might need to check ads from a wide variety of locales. Also, make sure you can actually target those locations.
Proxy pool quality is secondary, however still worth considering. The quality is best measured by looking at the composition of a proxy pool. A good quality residential proxy IP network should contain landline, mobile, or mixed IP addresses.
Depending on your budget, the price may also be an important aspect to think about. When it comes to proxies, you get what you pay for. Premium providers offer both well-performing proxies and plenty of additional tools to go with them. Meanwhile, mid-range and cheap providers have to cut corners to keep prices low, but they usually deliver satisfactory performance.

Where You Can Buy Proxies for Ad Verification

There’s a wide variety of proxy providers, and it can be resource-intensive to test them on your own. That’s why we used our expertise in the market to do the hard work for you. We tested and analyzed the most prominent providers and composed all the data into our annual Proxy Market Research.

However, you won’t find free proxies in our recommendations. Not only do they lack performance, free proxies can also compromise your security. You can read more about them in our article here.

3. Webshare

Quality proxies for less.

Get 40% off your first purchase.

General info

Webshare is the proxy provider of choice for any entry-level user – and even mid-range outfits will find something for them. For one thing, at 80 million IPs, the proxy network is large and offers global coverage. Plus, the infrastructure success rate is among the best in the industry. Only the response time and limited targeting options (nothing below the country level) leave something to be desired.

For ease of use, Webshare proxies can be integrated via an API. The company also offers a browser extension if you need to check a cheeky ad right at your work laptop. And if something goes amiss, support is provided via email and chat.

Bright Data is the largest proxy provider. It dominates the market with an outlandish proxy pool, which is just a little smaller than Oxylabs’ and consists of 400 million IPs. As a premium service, it gives all you need – global locations and targeting up to ZIP code level. The performance is also one of the best we’ve seen. The company is well known for its wide range of tools; however, setting everything up can be challenging for inexperienced users.

If you’re interested in all of the benefits this company has to offer, don’t expect it to come cheap. It’s one of the more expensive providers, especially if you need features like city or ASN targeting.

7. Dataimpulse

Cheap residential proxies with basic features.

Advertised pool: 90M IPs
Countries: 150+ with state, city, ASN, ZIP targeting
Rotation: Every request, sessions up to 120 min

However, the price doubles with extra features, like city, ASN, and ZIP code targeting. The provider has a proxy pool of 5 million addresses and allows you to target any of the 150 countries.

But don’t expect much more; the service doesn’t include proxy management tools, and its peer-to-peer addresses are slower than the top options on this list. But usage graphs reflect expenditure, which will help track your expenses.

8. Rayobyte

Residential proxies with a competent set of features.

Use the code proxyway to get 5% off.

General info

Protocols: HTTP, HTTPS, SOCKS5
Authorization: Credentials, IP whitelist (excl. rotating DC)

Support: 24/7 via email, ticketing system, or live chat

Rayobyte doesn’t disclose the size of its IP pool, but according to our tests, it controls one of the bigger proxy pools in the US, not that many IPs in Europe or Australia. You can target any of 150 countries, thousands of cities, and ASN. In terms of price, Rayobyte is especially competitive between 50 GB and 250 GB of traffic.

There are some drawbacks, too. Rayobyte’s residential proxies are slow, and you can only keep the same IP for as long as it remains online – no custom intervals.

For more information and performance tests, read our Rayobyte review.

9. Infatica

Reasonably priced proxies with granular targeting.

Use the code proxyway2024 to get 20% off your first purchase.

10. IPRoyal

Affordable residential proxies with non-expiring traffic.

Use coupon PROXYWAY30 to get a 30% discount.

General info

IPRoyal offers affordable pricing for its services. It owns 32 million IPs and allows you to specify over 150 locations by country, state, and city. IPRoyal uses pay as you go-based pricing, and the traffic stays until you use it. The pricing is slightly more expensive at fewer GBs, but it scales well at one terabyte of data.

Although this provider does offer a decent service, it can’t compete with the market giants. We’ve encountered more errors when running tests, and the proxies were slow.
