Deep Search
Also known as: ディープサーチ / 深層検索
Google AI Mode's deep-research capability that scrutinizes and synthesizes numerous pages for each sub-query generated by Query Fan-out, delivering research-grade answers beyond standard search.
Overview
Deep Search is a core AI Mode capability that reads and synthesizes a large number of web pages per sub-query. It is suited for creating research reports and supporting complex decisions — Google's answer to OpenAI's Deep Research.
Content Quality Requirements
Pages referenced by Deep Search are expected to contain primary information, concrete data, and clear structure. Google's official AI Optimization Guide details the content attributes that improve selection probability.
