Definition
AI Overviews are the AI-generated summary answers Google places at the top of some search results pages, synthesised from multiple sources and shown with links to those sources.
AI 概覽是 Google 在部分搜尋結果頁頂部放置的 AI 生成摘要答案，由多個來源綜合而成，並附上指向這些來源的連結。
In practice
An AI Overview is not a ranking position, and being cited in one is not the same as ranking first. The summary is assembled per query from pages the system judges to support the claim, so a page can be cited inside an overview while sitting below the first organic result — or not appear in the classic results at all. Two operational consequences follow. Impressions can rise while clicks fall, because the question was answered above the links. And citation tracking becomes a separate discipline from rank tracking, since no rank position describes it. Coverage varies by query type, language and market, and has changed repeatedly since launch.
AI 概覽不是一個排名位置，出現在其中也不等於排名第一。摘要按查詢即時組裝，取自系統判斷能支持該說法的頁面，所以一個頁面可以在概覽中被引用，同時排在自然結果之下——甚至完全不出現在傳統結果中。隨之而來有兩個營運後果：曝光可以上升而點擊下跌，因為問題已在連結之上被回答；而引用追蹤要成為與排名追蹤並行的獨立工作，因為沒有任何排名位置能描述它。覆蓋範圍按查詢類型、語言與市場而異，自上線以來已多次改變。
What it is not
- Not a featured snippet. A snippet extracts one passage from one page; an overview synthesises several sources.
- Not a guarantee of traffic. A citation can appear with no click at all.
- Not universal. It is absent for many queries, and its presence is not something a publisher controls.
Status
Emerging. The feature exists and is widely encountered, but its behaviour, coverage and citation logic have changed repeatedly since launch. Any description of how it works needs the date attached; treat older guides as historical documents.
