With the rapid development of the digital advertising industry, ad verification has become an important means to ensure the effectiveness of advertising and prevent fraud. Among them, the proxy service provider plays a key role.

There are currently two main types of proxy services on the market, namely rotating proxy ISP and dynamic residential proxy, each with its own characteristics. This article will discuss in detail the advantages and disadvantages of these two proxy methods in advertising verification to help advertisers and related practitioners better choose the appropriate proxy method.

1. Rotate proxy ISP

Rotating proxy ISP is a more traditional proxy method. Its principle is to hide the user's real IP address through the rotating use of multiple proxy servers. This approach protects user privacy to a certain extent, but advertisers may face some challenges when using rotating proxies.

Protect privacy: Rotating proxy ISPs hide advertisers’ real IP addresses by constantly changing proxy servers, thus increasing privacy protection.

Prevent fraud: Rotating proxy ISPs can effectively prevent some IP address-based fraud, such as IP blocking, malicious clicks, etc.

Limitations: However, due to the limited number of proxy servers of rotating proxy ISPs, the user's real IP address cannot be completely hidden, so it is still possible for advanced network tracking techniques to be identified. In addition, due to the limited number of rotating proxy ISP servers, IP address conflicts may occur when a large number of users use them at the same time.

2. Dynamic residential proxy

Dynamic residential proxy is an emerging proxy method, which is characterized by the fact that the IP address of the proxy server is real and widely distributed, and it can simulate the network behavior of home users. Dynamic residential proxies have clear advantages in ad verification compared to rotating proxy ISPs.

Real IP address: Dynamic residential proxies use real household or individual user IP addresses, making the advertiser's IP address more hidden and harder to track.

Wide distribution: The IP addresses of dynamic residential proxies are widely distributed, covering all parts of the world. This allows advertisers to advertise globally without worrying about geographical restrictions.

Simulate home user behavior: Dynamic residential proxy can simulate the network behavior of home users, such as usage duration, access frequency, etc. This makes the advertising behavior of advertisers closer to real users, thereby improving the accuracy of advertising verification.

Cope with complex network environments: Dynamic residential proxy can better cope with complex network environments and tracking technologies. Dynamic residential proxies protect advertisers' privacy by constantly changing their real IP addresses, even in the face of advanced web tracking technology.

It is recommended to use lunaproxy, which provides 200 million proxy resources covering 195+ regions around the world. It is cheap and has comprehensive IP types. It is suitable for various business scenarios and is one of the most reliable proxy service providers.

3. Conclusion

In summary, dynamic residential proxies have significant advantages over rotating proxy ISPs in ad verification. Dynamic residential proxies use real household or individual user IP addresses, making the advertiser's IP address more deeply hidden and harder to track.

At the same time, its IP addresses are widely distributed and can simulate home user behavior, making advertising closer to real user behavior and improving the accuracy of advertising verification. In addition, dynamic residential proxies can better cope with complex network environments and tracking technologies. Therefore, dynamic residential proxies are a more suitable choice when it comes to ad verification.

However, this does not mean that rotating proxy ISPs has no value. For some advertisers who have low privacy protection requirements, rotating proxy ISPs is still a viable option. 

Moreover, rotating proxy ISP also has its own advantages, such as relatively low cost and simple operation. Therefore, when choosing an appropriate proxy method, advertisers should make comprehensive considerations based on their own needs and actual circumstances.
