Amazon has rolled out a novel AI-driven search experience, powered by a large language model, in the United States market. This new feature defaults to the 'Alexa for Shopping' tool, effectively replacing its previous shopping assistant bot, Rufus. The innovative functionality delves into user search intentions, automatically generating AI-crafted product comparison reports, personalized recommendations, and succinct review summaries. For instance, when users initiate searches for particular products, the system presents a meticulously structured comparison panel on the search results page. This panel showcases horizontal comparisons of key parameters, interpretations of pain points in specific scenarios, and insightful purchasing advice. This capability is underpinned by the COSMO algorithm, which constructs a knowledge graph by extracting data from product detail pages and reviews. This marks a significant transition from a 'search ranking' approach to a 'decision support' logic. Consequently, sellers must optimize the structured information in their listings to conform to the AI's crawling logic; failure to do so may result in their products being overlooked in the comparison process due to unclear tags or missing parameters.
