您的新书店客户新推出了一个培训系列图书并正在投放相关广告系列。广告中附带了说明手册。他们在 Campaign Manager 360 的 Floodlight 代码中添加了计数器代码。您应当使用下面哪种方法来统计下载该手册的用户数？

The correct answer is Unique count method. To count the number of users who download the manual, a unique count method is necessary. This method tracks each individual user only once, regardless of how many times they download the manual. This provides an accurate measure of distinct users engaging with the content. The Custom count method is used for specific, non-standard counting scenarios, often requiring custom JavaScript, which isn't needed here. The Standard count method would count every download instance, meaning if one user downloads the manual five times, it would count as five downloads, not five unique users. The Session-based count method would count each download within a single user session, but if the same user downloads the manual in different sessions, they would be counted multiple times, which is not the goal here.
