We are now at a turning point where the very “decision-maker” in the purchasing process is undergoing a fundamental change. Until now, purchasing decisions were ultimately made by “people.” Consumers searched, compared, read reviews, and decided to purchase on e-commerce sites or in physical stores. The starting point of this process was search engines, and companies competed to “rank highly in search results” through investments in Search Engine Optimization and advertising.
However, consumer information-gathering behavior is now changing significantly. Instead of “searching,” consumers are increasingly “consulting” AI, including their objectives and preconditions. They ask conversational AI such as ChatGPT and Gemini in natural language, for example, “Please recommend camping gear for beginners,” or “What time-saving home appliances would you recommend for dual-income households?” Rather than returning a list of links, AI presents options as recommendations accompanied by reasons.
The change occurring here is not merely an evolution of search behavior. It is a structural transformation in which AI is being incorporated as a new decision-making entity within the purchasing decision process itself.
In this article, we position this change as a management issue for the retail industry and propose “AIO (AI Optimization)” as the next theme after Search Engine Optimization. AIO refers to initiatives for information design and structural design that enable AI to understand, compare, and recommend. Today, retail companies are being asked whether they can evolve into entities that are chosen by AI before they are chosen by consumers.
