With the help of Google AdSense for Search (AFS), publishers may make money from their websites by incorporating Google-powered search features along with pertinent ads. By improving ad relevancy, targeting precision, and revenue optimization through sophisticated analytics, machine learning, and ethical data practices, big data powers Google AdSense for Search. The foundation of AFS is Big Data Analytics, which optimizes ad delivery and revenue generation by processing massive volumes of data produced by user queries, ad interactions, and behavioral patterns. This study examines how big data plays a crucial part in improving the performance, personalization, and relevancy of advertisements shown through AFS. Real-time data processing frameworks, natural language processing (NLP), and sophisticated machine learning models are used to match user intent with highly tailored ads.Additionally, to maximize return on investment (ROI) for publishers and advertisers, cost-per-click (CPC) and click-through rates (CTR) are optimized through the use of dynamic pricing algorithms and predictive analytics. Notwithstanding its advantages, AFS has drawbacks such ad fraud, scalability issues, and data protection issues that call for creative fixes and adherence to regulations. This study sheds light on the potential and difficulties of big data in AFS while offering ideas into how it can revolutionize digital advertising networks.
