What is a Google AI Overview, and where do its answers come from?

Mr Lim got his answer before he saw a single website

It is late, the kopi is going cold, and Mr Lim is closing his small trading company in Singapore. He types the whole worry into Google:

how long does it take to strike off a private limited company in Singapore and what do I file first

Before any blue link, Google shows a paragraph its AI has written, with a few source cards beside it. That paragraph is an AI Overview. He reads it and closes the tab.

Down the road, a corporate secretarial firm explains strike-off better than most, and ranks. But Mr Lim stopped reading above it. Was that firm one of the cards? Is yours? From where you sit, you cannot tell.

Once he would have typed "strike off company" and opened three results. So your question moves too: not only "do we rank?", but "were we one of the sources?"

Google now answers first, from pages it already keeps on file

Google calls an AI Overview an AI-generated snapshot with key information and links to dig deeper ¹. It appears only when Google judges it adds something, and Google admits it often does not appear ².

Picture a hotel concierge. A guest asks, and the concierge answers from the brochures on the desk, handing over two or three. The guest seldom walks to the rack. Your website is a brochure. The question is whether it is on the desk.

And the desk is open where you trade. Google's help page lists Singapore and Hong Kong, with English, Chinese (Simplified and Traditional), Malay and Tamil among the languages ¹. Chinese and Malay arrived on 20 May 2025, when Google announced more than 200 countries and territories and more than 40 languages ⁶. By June 2026 it counted over two and a half billion monthly active users ⁵. A busy concierge, then. Google AI Mode is a separate mode for back-and-forth questions ¹; this page stays with the summary.

The longer the question, the likelier the summary, and the fewer the clicks

The best independent measurement we know of is American: Pew Research Center followed the browsing of 900 US adults in March 2025 ³. We have not measured Singapore or Hong Kong, so read this as the shape of the habit.

The longer the question, the likelier the summary, and Mr Lim's question is the long kind. Google says the clicks that do happen are higher quality, with people staying longer on the site ². Both can be true.

In other words, the summary is often the whole visit, and it was written from somebody's page.

The sources are ordinary pages Google can find and quote

Google is refreshingly direct. To be a linked source in an AI Overview, a page must be indexed (in Google's catalogue of pages) and eligible to show with a snippet (the short extract of text under a result). In Google's words, "there are no additional technical requirements" ². No special file, no sign-up.

What Google does list are ordinary basics ²:

• Let Google's reading robot in: your robots.txt (the file telling robots where they may go) and firewall must not block it.
• Put the important facts in words, not only in pictures.
• Keep the hidden labels in your code (structured data: a block telling a machine "this is the firm's name and address") matching the page.
• Keep your Google Business Profile up to date.

We read the home pages of 133 Singapore firms found through Google Maps on 27 October 2026, and 113 of them loaded. On 64 of those 113, the page's code never named the business for a machine to read. We did not check whether any appear in an AI Overview; absence from a summary is an observation, not a diagnosis. A brochure without the firm's name is a hard one for the concierge to hand over.

Google's switches can take your page out of the summary, never put it in

Some owners want their words kept out. Google points them to its snippet controls ², set out in its robots meta tag reference (short instructions in a page's code for Google's robot) ⁴:

• nosnippet stops the short extract under your result and stops the content being used as a direct input for AI Overviews and AI Mode.
• data-nosnippet does the same for one part, say a price list.
• max-snippet caps how many characters may be used, and noindex takes the page out of Search.

The catch: the switch that keeps your text out of the summary also removes the extract under your ordinary result. A thorough way to become invisible.

A finer switch is in testing. On 3 June 2026 Google announced a toggle in Search Console (its free dashboard for site owners) to opt a site out of its generative AI features, AI Overviews included. A site that opts out gets no traffic or impressions (times it is shown) from them ⁵. The test began with some UK site owners; the post, last updated on 31 August 2026, gives no date for anywhere else.

Two minutes, one question: is your answer on the desk?

Test this alone, today. Type one question a customer really asks, as a full sentence. If an AI Overview appears, open its source links and note what they say that your page does not. Then look for that answer on your own page, in words, not in a banner image or a PDF.

Nobody can promise you a place in the summary, and we do not. What you control is whether your page is a good brochure for the desk: in Google's catalogue, allowed an extract, and saying plainly who you are, what you do, where, for whom, at what price and when you are open.

We work with owners in Singapore and Hong Kong on that plain work. The free scan comes first: it reads your site the way a machine does and shows you what it finds today.

Questions people ask

Can I switch off AI Overviews when I search?

No. Google calls AI Overviews a core Search feature that cannot be turned off. The Web filter, chosen after a search, shows only text links without the summary ¹. That changes what you see, not what your customers see.

Does my website need special code to appear in an AI Overview?

No. Google says a page must be in its index and eligible to show with a snippet, with no additional technical requirements ². The basics apply: let Google's robot in, key facts in words, code labels matching the page.

How do I keep my text out of AI Overviews?

Use nosnippet for a whole page or data-nosnippet for part of it. Google says nosnippet stops the content being a direct input for AI Overviews and AI Mode ⁴. It also removes the extract under your normal result.

Will I see AI Overview visits in Search Console?

Yes, though not on their own yet. Google counts them in the Performance report, under the Web search type ². In June 2026 it began testing separate reports on AI appearances, starting with some UK site owners ⁵.

Do AI Overviews appear in Chinese in Hong Kong?

Google's help page lists Hong Kong among the places with AI Overviews, and Chinese (Traditional) and Chinese (Simplified) among the languages ¹. Chinese support was announced in May 2025 ⁶. A bilingual site should state its facts in both languages.
