But traditional methods often use separate steps for creating ad content and keyword targeting, which wastes time and makes ads work less well than they could. This article talks about a new method called Contextual Ad Generation and Targeting (CAGT). It uses Large Language Models (LLMs) to create ad content and improve keyword targeting all at the same time, within a single structure. To make ads more relevant and useful, CAGT uses adaptable prompt engineering and reinforcement learning-based feedback loops. CAGT increases the click-through rate (CTR) by 23% and the conversion rate (CR) by 18% compared to traditional methods. These results were found using a dataset of 10 million ad impressions from a major e-commerce site. When CAGT was used in a commercial ad network, it showed even better results, with an average increase in click-through rate (CTR) of 27% and an increase in click- through rate (CR) of 21% across 50 advertising programs over 3 months. The results show that LLMs could change contextual advertising by making ads more interesting and improving targeting all at the same time.
