In China, the rapid development of the internet industry has become a thing of the past. Faced with increasingly precious traffic, brands and advertisers need to put in more effort to “explore” and manage. Advertising monitoring naturally becomes an indispensable part of the advertising placement industry chain. Through advertising monitoring, advertisers can understand the effectiveness of their placements and further optimize strategies to gradually improve the return on investment. This article will explore how advertising monitoring is implemented in the Chinese market and what the current state of advertising monitoring is like.

What to monitor?

In China, advertisers also focus on the exposure, clicks, and in-app interaction effects of advertisements.

Exposure Monitoring: Also known as “impression monitoring,” it is usually the channel vendors who pass the data back to the advertisers.

Click Monitoring: Monitoring the number of clicks, which can be collected by the advertisers themselves or passed back by the channel vendors through data transmission.

In-App Monitoring: Refers to the monitoring of behaviors/events within the APP, such as basic PV, UV, APP activation/registration/login, etc., and user retention on the next day, 7 days, 30 days, pay rate, ARPU value, etc. These data are generally collected through the integration of third-party monitoring companies’ SDKs within the app, and the interfaces provided by different apps will vary.

Advertising Monitoring Process

To monitor the effectiveness of advertisements, advertisers fill in the corresponding monitoring address when creating the smallest unit of an advertisement, which is the creative. The monitoring URL generally includes the following macros: creative ID or advertisement ID identifier, user device identifier, IP, UA, operating system, etc., and special ones may include CLICKID, CALLBACK.

The entire monitoring process can be roughly divided into three steps:

Advertisers/ad agencies place advertisements with media outlets. When users browse and click on the advertisements, the media will report the data to the advertiser or a third-party advertising monitoring platform. Common third-party platforms include: Umeng, adMaster, and Miaozhen.
After users click on the advertisement, they enter the landing page and participate in the advertising activities, such as downloading and launching the APP. After completing a series of operations, the APP uploads the user data to the advertising monitoring platform through the corresponding interface. Of course, other interactive media such as websites and H5 can also monitor the interaction data from the source of the advertisement through tracking codes and embedded points.
After attribution through certain methods, the user’s relevant data will be associated with the channel merchant and ultimately fed back to the advertiser/ad agency.

Data Reporting Methods for Advertising Monitoring: SD& APIK

Advertising data monitoring in China is mainly implemented through SDK and API methods. The technical principles of the two are the same, both collecting user information and transmitting it back to the monitoring platform’s server for comparison. For example, when a user clicks on an advertisement link with tracking parameters, the monitoring platform collects the user’s IP, operating system version, device model, and other information through the link and stores it.

If a user clicks on an advertisement and is redirected to the App Store to download and activate the APP online, the APP will also collect all the user information stored by the monitoring platform.

Then, by matching the information collected when clicking on the link with the information collected after downloading and activating, subsequent conversion and other indicators can be monitored.

The SDK method is simple, easy to use, and powerful. Media outlets integrate SDKs into their Apps, and after completing certain development work, they can meet the vast majority of the needs of third parties and advertisers, with high accuracy and real-time performance.

The API method is flexible, versatile, and applicable to both Apps and mobile web pages. However, it requires media outlets to undertake some development work in accordance with API monitoring standards. API monitoring is divided into two types: C2S (Client to Server) API and S2S (Server to Server) API.

C2S, or Client to Server, refers to the terminal issuing a request instruction to the order placement proxy server. After the terminal receives and completes the instruction, it sends the completed instruction to the third-party monitoring proxy server, which conducts accurate traffic monitoring through mutual counting. Under the C2S model, user actions are directly reported to the third-party monitoring platform’s server, ensuring the timeliness and accuracy of the data. Renowned brand advertisers such as AdMaster and Nielsen often prefer this method to ensure seamless traffic authenticity verification.

S2S, or Server to Server, refers to the terminal issuing a request instruction to the order placement proxy server and then sending the completed instruction back to the order placement proxy server, which in turn sends the data to the third-party monitoring proxy server. This design may affect the timeliness of monitoring data while protecting user privacy, as it requires additional steps. Media outlets sometimes opt for S2S as an alternative strategy due to concerns over data security and may not support C2S monitoring.

C2S is more accurate and can reduce media cheating, commonly used by brand advertisers, but C2S requires client releases for each monitoring, making the implementation more complex.

Click Monitoring Methods: Synchronous Monitoring & Asynchronous Monitoring

Synchronous monitoring integrates the monitoring code with the landing page link. When a user clicks on an advertisement, they first visit the monitoring link, jump to the monitoring company’s server, and then jump to the landing page. Synchronous monitoring ensures the immediacy of the monitoring but may affect the user experience. In addition, synchronous monitoring does not support the transmission of parameters such as IDFA.

Asynchronous monitoring, on the other hand, directly redirects users to the landing page after clicking on the advertisement, with the media server sending a monitoring request to the monitoring company’s server. The asynchronous mode ensures a good user experience, but data transmission may be delayed. Moreover, since the request is sent by the server, the visits collected by the monitoring company all come from the same IP segment. If the client is targeting a specific city, determining the region solely based on the IP can lead to significant geographical discrepancies.

Current State of Advertising Monitoring

The mainstream third-party advertising media monitoring tools in China are TrackMaster introduced by AdMaster and AdMonitor introduced by Miaozhen. However, some dominant media outlets refuse third-party monitoring:

The first kind is top-tier vertical media, mainly out of concern for protecting their own data, fearing that clients obtaining the data will affect the media’s valuation and traffic value.
The second kind is dominant internet platforms, which often provide their own developed monitoring tools to clients.

Brands and advertisers must monitor advertising to better understand the effects, prevent data fraud, and continuously optimize the media mix, timing, geography, and creativity using the data obtained. The choice of monitoring mode depends on factors such as the brand’s demand for traffic authenticity, user privacy protection, and system compatibility between both parties. As the market evolves, China’s advertising monitoring methods may continue to evolve to adapt to the ever-changing advertising environment.
