Definition

Deep research is an AI-assisted research mode in which a model autonomously conducts multi-step web searches — querying, reading, synthesizing, and iterating across many sources — to produce a comprehensive answer to a complex question. It is a form of agentic search applied to research tasks. Deep research mode dramatically expands the citation surface. Deep research sessions typically retrieve and synthesize a significantly greater number of sources compared to single-turn AI searches, enhancing the breadth of information. Brands that have built comprehensive, well-structured content across a topic domain are significantly more likely to appear in deep research outputs than brands with sparse or fragmented coverage. Deep research rewards topical completeness and citation architecture — not just single optimized pages.
