Generative AI to Become New Discovery Layer in E-Commerce
A report by Similarweb indicates that generative AI is increasingly influencing online purchase decisions, appearing in over 11% of shopping journeys prior to transactions, up from under 5% two years ago. However, traditional search remains crucial, with 89% of AI-influenced journeys also using search engines. AI is primarily used in early stages for problem definition and product comparison, while search is relied upon for specific product checks. This creates challenges in attribution, as last-click models often misattribute AI-driven conversions to search or direct traffic. Retailers must now optimize for visibility across multiple digital layers, including AI-generated answers and on-platform shopping assistants like Amazon's, and ensure structured product data to enhance AI recommendations.
