Visual content selection is of utmost importance in the ever-changing realm of online advertising as it directly influences the ability to attract user attention and stimulate interaction. The emergence of artificial intelligence (AI) technology has led to the growing use of AI generated photographs and advertisements in conjunction with conventional human-generated pictures. The objective of this study is to evaluate the effectiveness of AI-generated images compared to human-generated images in the context of online advertising, particularly on Google Ads. Through the examination of variables like as click-through rates (CTR), conversion rates, and user engagement, this study explores the influence of both picture formats. User perceptions and preferences are investigated using a qualitative approach that includes in-depth interviews and content data analysis. Research findings indicate that although AI generated graphics provide the flexibility to be scaled and personalized, human-generated images elicit a stronger emotional impact and authenticity. The present study provides pragmatic suggestions for advertisers and examines the ethical implications linked to AI generated visuals.
