Starting September 9, 2025, Google will expand AI Mode, the most powerful search experience, to Hindi, Indonesian, Japanese, Korean, and Brazilian Portuguese. This AI upgrade not only covers more users, but also points to the Gemini-driven "Q&A exploration + deep linking" paradigm, and content teams and sites should immediately carry out multilingual AI search optimization and GEO layout.
1. Key points and impact of the update

AIMode is launched in Hindi, Indonesian, Japanese, Korean, and Brazilian Portuguese, combining AI understanding and local semantics to solve the problem of "keyword migration" in cross-language search, and improve the quality and readability of AI answers to complex questions.
2. Core features of AI search experience
AI Mode helps users change from "input words" to "ask questions" through generative answers, key evidence aggregation, and follow-up exploration guidance. AI's ability to parse long problems, multiple constraints, and multiple steps has been significantly enhanced.

AI Mode prefers content with clear structure, verifiable facts, and can be cited by AI. Multilingual sites need to provide a consistent information structure, clear summary paragraphs, and extractable bullet points to increase the probability of being called and displayed by AI.
