Question

RT,想问下IFDA具体是指什么？，我做的一个免费工具应用上有个滚动视图，滚动视图显示一些产品信息，点击就跳转到网页这样算不算使用了IFDA？如果不算的话能否跟我说下具体是怎样才算用了IFDA？

Answer 1

IFDA is a unique identifier. The general situation is as follows
1. For example, if a certain software knows that a unique individual like me (unique according to IFDA) often looks at digital products, it will recommend digital products to me based on my unique identification (IFDA). Play a role in advertising targeting.
2. Calculate the number of advertisements based on IFDA. Third-party advertising platforms use more and are more accurate.
Pan-advertising does not require IFDA.
