Google AI Overviews: What They Are and How to Get Cited

AI Overviews (formerly "SGE" — Search Generative Experience) is Google's feature that shows an AI-generated, synthesized answer at the top of the search results page, above the traditional organic links, citing two to four sources chosen for how directly usable they are.

Why it matters for AI visibility

AI Overviews reshapes the layout of a Google results page. The generated answer often takes the most visible spot — above organic position 1 — and includes direct citations to the source pages. For cited sites, that's a stream of qualified traffic and a credibility signal. For everyone else, it's one more screen between the user and their content.

AI Overviews picks its sources the same way other generative engines do: it retrieves relevant passages through a RAG-style system, then the model keeps the extracts it can use most easily. The selection criteria reward passages with an extractable structure, the presence of structured data (JSON-LD Article with dateModified, author with sameAs), and fresh content.

One technical point worth knowing: Google-Extended, the token Google uses to train its Gemini models, is separate from the Googlebot token in robots.txt. Blocking Google-Extended doesn't affect traditional SEO crawling, but it can affect how well the model learns the patterns in your content. The two tokens have to be managed separately, depending on the site's strategy.

Technical accessibility is a precondition: content rendered only in client-side JavaScript (with no server-side rendering) exposes little or no content in its raw HTML, which leaves the passages out of reach of Google's crawler for AI Overviews.

A concrete example

An e-commerce site selling hiking gear publishes a buying guide, "How to choose your trail running shoes." The article is built around H2 sections written as direct questions ("Which outsole for which terrain?", "What's the difference between zero drop and an 8mm drop?"), and each section opens with a self-contained 50-word paragraph backed by sourced figures.

The result: AI Overviews pulls two extracts from this article to answer queries like "trail shoes stiff or soft outsole" — queries the site didn't rank first for in traditional search, but whose passages matched exactly what the model was looking for to build its answer.

That's the structural difference between SEO and GEO: a well-structured passage can be cited even when the page isn't ranked first.
