AI Optimization Terms

The paradigm where autonomous AI agents—rather than human users—browse, explore, evaluate, and select content, products, services, or information on behalf of people. In agentic discovery, AI agents act as intelligent intermediaries that navigate digital ecosystems, make comparisons, apply user preferences, and surface recommendations without requiring direct human interaction with source websites or applications.
