AI Overviews (AIO)

AI Overviews (AIO)

AI Overviews is the answer box displayed at the very top of Google's search results page, in which generative AI (Gemini) summarizes multiple web pages into a single answer. It became generally available in Japan in August 2024, and in 2025 was joined by "AI Mode," which lets users continue the conversation. Efforts to get cited in this answer box are called "AIO" or "AI Overviews optimization." How it works: For a search query, AI Overviews retrieves the regular search results, reads the content of several of those pages, generates a summary, and displays the pages it relied on as links. The cited sources are not necessarily the pages ranked first; pages that contain a passage answering the question concisely tend to be selected. Whether an overview appears at all also depends on the type of query (common for informational queries, less common for branded or purchase-intent queries). In practice: For queries where AI Overviews appears, clicks on regular results decrease, but being cited as evidence for the summary earns brand exposure. Teams therefore track, for their target keywords, whether AI Overviews is shown and whether their page is cited when it is, and make improvements such as placing the conclusion right under the heading, tidying FAQs, and adding structured data. Note that the abbreviation "AIO" is used in two senses depending on context — "AI Overviews optimization" and "AI Optimization" in general — so read materials carefully. Related tools: Tools that can measure whether AI Overviews appears and whether you are cited, at the keyword level, include User Insight, BringRitera, Mieruca GEO, AKARUMI, OtterlyAI, and Writesonic.
