Google is testing a merged feature called "AI Overview + AI Mode" on mobile devices worldwide, allowing users to engage in multi-turn conversations directly on the search results page without switching tabs. This experience is currently available only on mobile devices, supporting text, voice, and image inputs, with conversation lengths up to three times that of traditional searches, while retaining citation sources and web ranking logic.

Robby Stein, Vice President of Products, stated that the new design aims to eliminate the "whether to use search or chat" decision cost, saying "users can ask follow-up questions continuously, and the system will provide summaries and conversational in-depth answers within the same interface." On the technical side, the AI mode uses a "query expansion" mechanism to parallelly fetch knowledge graphs, real-time financial/sports data, and then synthesize answers with references; if users continue to ask questions, the model will generate personalized responses based on the history.

Internal data shows that the click-through rate of result pages with AI overview has decreased by about 36%, but dwell time and conversion quality have significantly improved; Google emphasized that the cited webpages are still counted as traffic in Search Console, and content creators do not need additional optimization to be "selected." On the market side, Gemini's monthly active users exceeded 650 million in November, and Google plans to merge the chat interface with the AI overview, which has 2 billion monthly active users, to compete with OpenAI's ChatGPT Search, and in the future, add agent functions such as restaurant reservations and ticket purchasing.
