AI Overviews and your website: what changes when Google answers the question

Search Google for something that takes a few sentences to explain and you may get an answer written by Google’s AI before you reach any website. That matters to anyone who relies on Google to bring in customers or readers.

This explainer sets out what Google says about how a site gets linked from those answers, how the visits are counted and what controls a site owner has. It is based on Google’s documentation as it stood on 11 October 2026, which describes how its systems are meant to work, not how much traffic any one site will gain or lose.

Two features, both listed for Australia

AI Overviews are the AI-written summaries that appear within ordinary search results, with links to pages that support them. In its guide for site owners, Google says an AI Overview appears only when its systems judge it adds something to classic Search, so they “often don’t trigger”.

AI Mode is a separate, conversational way to search. Google describes it as its most powerful AI search experience: you ask a question, get an AI-written response with links, and can ask follow-up questions.

Google’s help pages list Australia among the countries where each feature is available, and English among the languages.

People searching can’t switch AI Overviews off. Google calls them a core Search feature, like knowledge panels, and says such features can’t be turned off.

Google is also plain about accuracy. Its help page says AI Overviews “can and will make mistakes”. The thumbs-down icon at the bottom of an overview opens a “Report a problem” option. Google describes that as feedback to improve the feature and doesn’t promise a correction.

How a page gets linked

Both features can use what Google calls query fan-out: they run several related searches across subtopics and bring the results together. Google says that lets it show a wider set of links than a classic search, and that the two features may use different models, so their links will differ.

For site owners, the main point in Google’s guide is that nothing new is required:

• A page must be indexed and eligible to appear in Google Search with a snippet. Google says there are no additional technical requirements.
• Google says you don’t need new machine-readable files, AI text files or markup, and there is no special schema.org structured data to add.
• Meeting every requirement doesn’t guarantee Google will crawl, index or show a page.

Google says its existing search fundamentals “continue to be worthwhile”. Its examples include allowing crawling in robots.txt and in any content delivery network or hosting set-up, making content easy to find through internal links, putting important content in text rather than only in images, making sure structured data matches the visible text, and keeping Business Profile and Merchant Center information up to date.

The hosting item deserves a look, because a bot-blocking setting can stop Googlebot along with other crawlers. Our story on Cloudflare’s AI crawler settings covers one case where a “Block” option does that.

How the visits are counted

Google reports traffic from both features in Search Console, inside the Performance report under the Web search type. They are part of the overall totals. Google’s guide doesn’t describe a separate view for them.

Search Console’s help page gives the counting rules:

Measure	AI Overviews	AI Mode
Click	Clicking a link to an external page in the overview counts as a click	Clicking a link to an external page counts as a click
Impression	Standard impression rules apply	Standard impression rules apply
Position	The overview occupies a single position, and every link in it is given that position	Follows the same method as a search results page

A follow-up question in AI Mode is treated as a new query, so its clicks, impressions and position are counted against that new question. On our reading, because every link in an AI Overview shares the overview’s position, a page’s average position can reflect where an overview sat, not where its ordinary result ranked.

On whether these visits are worth having, Google says that when people click through from a results page with an AI Overview, the clicks are “higher quality”, meaning visitors are more likely to spend more time on the site. That is Google’s own statement, and its guide gives no figures for it. Google suggests tracking conversions and time on site in a tool such as Google Analytics. Our guide to five Google Analytics reports worth checking once a month shows where to find enquiries by channel and by landing page.

The controls you have

Google says AI is built into Search, so crawling for these features is controlled by the same robots.txt rules as Googlebot. To limit what is shown from a page, the controls are the existing snippet settings:

• nosnippet stops Google showing a text snippet for the page. Google says it applies to web search, Google Images, Discover, AI Overviews and AI Mode, and also prevents the content being used as a direct input for AI Overviews and AI Mode.
• max-snippet sets a maximum number of characters for the snippet, and Google says it also limits how much of the content may be used as a direct input for the two AI features. Google says the limit doesn’t apply where a publisher has separately granted permission, such as through a licence agreement.
• data-nosnippet marks part of a page that must not be used in a snippet. It works on span, div and section elements. Google lists it among the controls for limiting what is shown from a page, but describes it only in terms of snippets.
• noindex removes the page from Search entirely.

The Google documents we checked describe no setting that removes a page from AI answers while leaving its ordinary search snippet untouched. The snippet controls apply to both. On our reading, that makes nosnippet a costly choice for most business sites, because the page loses its description in ordinary results too. The narrower data-nosnippet attribute suits a specific passage you don’t want shown in snippets.

Google-Extended is not that setting either. It is a robots.txt token that controls whether content Google crawls can be used to train future Gemini models and for grounding in the Gemini apps and Vertex AI. Google says it does not affect a site’s inclusion in Google Search and is not a ranking signal.

If content still appears in AI features after you add a control, Google’s advice is to check with the URL Inspection tool that Googlebot can see it, then wait: recrawling can take from several days to several months.

What this means for a small site

Offers of special “AI Overview optimisation” files or markup don’t match Google’s guide, which says none are needed. To spot technical problems, Google suggests verifying your site in Search Console.

Google’s documents don’t settle the effect on your own enquiries, and Search Console doesn’t separate AI traffic from ordinary results. Your own month-to-month figures are the nearest measure.

Checklist

• Verify your site in Google Search Console. Google suggests it for finding technical problems, and its Performance report, under the Web search type, is where clicks and impressions from AI Overviews and AI Mode are counted.
• Check Googlebot isn’t blocked. Ask whoever manages your hosting or content delivery network to confirm that robots.txt and any bot-blocking setting still allow Googlebot.
• Put important content in text. Google’s list includes making important content available in textual form, so check that nothing essential appears only inside an image.
• Update your Google Business Profile. Google names up-to-date Business Profile information among the search fundamentals that still apply to AI features.
• Use data-nosnippet for a passage you don’t want in snippets. Ask your web developer to add it to the span, div or section element around that passage.
• Report a wrong AI Overview. Use the thumbs-down icon at the bottom of the overview and choose “Report a problem”. Google treats it as feedback and doesn’t promise a correction.
• Question offers of special “AI Overview” files or markup. Google says no new machine-readable files, AI text files or special schema.org structured data are needed.
