Our modeling system is based on a new hash system that anonymizes user device description information, and gradually focuses on modeling and predicting users' real-time interests. At present, we have achieved very positive optimization effects, which can help advertisers and media publishers achieve sustained growth in an increasingly stringent privacy regulatory environment. Our in-app bidding technology ranks among the top in the industry, maximizing the value of each ad placement and efficiently predicting LAT traffic, allowing you to achieve transparent, efficient, and stable revenue growth even in the "post-IDFA era".
