What is AI Overviews? Plain-English Definition

In more detail

AI Overviews are the AI-written summaries Google shows above the normal search links — the answer assembled for you before you click anything. Ask a question, and instead of choosing among websites, you often just read a paragraph Google’s AI stitched together from them.

It matters twice over. As a reader: instant answers, but AI-written ones — worth double-checking, since summaries can garble their sources. As a website owner: many visitors now get their answer without ever visiting, a shift that’s upending how sites earn traffic and fueling the rise of GEO.

📌 See it in action

You search ‘how to get red wine out of a carpet.’ Above every link sits an AI paragraph: blot, don’t rub; cold water; salt or baking soda. Sorted — you never click anything. The cleaning site whose advice fed that summary got no visit at all, which is exactly why publishers are nervous.
