1. How proxy checkers work

Proxy checkers are software tools used to detect and verify whether the IP address accessing an advertising platform is provided by a proxy server. Its working principle mainly includes the following steps:

IP identification and verification: Proxy checkers analyze the visitor's IP address to determine whether it comes from a known proxy server. This identification usually relies on the characteristics of the proxy server, such as public proxy lists or anonymous proxy detection.

Filtering and blocking: If a visitor is detected using a proxy server, the proxy checker can selectively filter or block these visits to ensure that the target group for advertising is real users rather than robots or malicious attackers.

Real-time update and anti-fraud technology: Advanced proxy checkers usually have the ability to update the proxy database in real time, and combined with anti-fraud technology, identify and respond to complex IP camouflage behaviors to ensure the advertising effect and ROI of advertisers.

2. The role of proxy checkers in online advertising

Online advertising faces challenges from automated tools and malicious behavior. The role of proxy checkers is reflected in the following aspects:

Improve advertising effectiveness: By excluding proxy IP access, proxy checkers ensure that advertisers' ads are only displayed to real users, thereby improving the effectiveness and conversion rate of advertising.

Protect advertising budgets and brand reputation: Prevent advertising budgets from being consumed by invalid clicks and automated robots. Proxy checkers help maintain advertisers' budget security and brand reputation.

Comply with the policy requirements of advertising platforms: Most advertising platforms require advertisers' delivery behaviors to comply with their policy requirements, including using real user traffic and avoiding cheating. Proxy checkers help advertisers comply with these requirements and reduce the risk of being punished by the platform for violations.

3. How to choose a proxy checker

When choosing the right proxy checker, it is crucial to consider the following key factors:

Detection accuracy and real-time performance: Ensure that the proxy checker has the ability to identify IPs with high accuracy and update in real time to effectively respond to the ever-changing proxy technology.

Ease of use and integration: Choose a proxy checker with a user-friendly interface that is easy to integrate into existing ad delivery platforms to reduce operational complexity and integration costs.

Supported ad platforms and ad types: Make sure the proxy checker supports the ad platforms you are currently using and their specific ad types to ensure smooth delivery.

Conclusion

Proxy checkers play a key role in ensuring the quality and effectiveness of online advertising. By understanding its working principles, application scenarios and selection guidelines, advertisers can more effectively deal with automated attacks and improper clicks, improve advertising ROI and protect brand interests. Choosing a proxy checker that suits your needs is an important step to ensure the success of ad delivery.
