Abstract
To address the existing problems of insufficient accuracy of user portraits in intelligent advertising recommendation, high privacy risks, poor real-time delivery performance and low marketing efficiency for Small and Medium-sized Enterprises (SMEs), this paper constructs an intelligent advertising recommendation system for SMEs that integrates the fused LightGBM-KNN algorithm with privacy-preserving computation. Privacy-preserving computation is adopted to achieve secure fusion of multi-modal operator data. A lightweight user portrait model integrating LightGBM and the KNN algorithm is built to accurately classify residential and commercial users. Kafka is utilized to realize real-time secure backhaul of advertising data and iterative optimization of delivery strategies. Comparative experiments verify that the Click-Through Rates (CTR) of advertisements targeting residential and commercial users increase by 83.96% and 68.09%, respectively, and the overall conversion rate increases by 201.47%. The optimized CTR reaches 3.95%, and the conversion rate reaches 2.05%. Further performance improvements can be achieved through technological upgrades in future research. Balancing privacy compliance and advertising delivery efficiency, the proposed system provides effective technical support for the precision marketing of SMEs.
