What is AI Overviews, and what it means for your traffic

AI Overviews are the short AI-written answers Google shows above its normal results, with links to the pages it drew on. They answer many questions on the results page itself, which changes how many people click through to your website.

The short answer

So, what is AI Overviews? It is the AI-written summary that Google places at the top of some search results. Google describes it as a snapshot with key information and links to dig deeper1.

The summary is written by Google's generative AI, drawing on pages found by its core search ranking systems3. Each overview links to some of the pages it drew on, so a reader can check the answer or read further.

For a business, two things follow. Your page can be one of the links inside the answer, which puts you in front of the reader before any normal result. And because many questions are now answered on the results page, fewer people may need to click through to anyone.

What an AI Overview looks like

An AI Overview sits above the normal list of results. It usually opens with a one or two sentence answer, then adds short sections, bullet points or steps.

Small link icons sit next to each part of the answer. Each one opens a card for a source page, with its title and the name of the website. Some overviews also show a video, and many end with a follow-up question inviting you to ask more.

The overview is not a separate product you sign up for or pay to appear in. It is part of normal Google Search, and it appears on its own when Google decides it will help.

When Google shows an AI Overview

Google says it shows an AI Overview when its systems decide that generative AI can be especially helpful1. Its example is when you want to understand information from a range of sources quickly1. It does not publish a list of the searches that trigger one.

Independent research gives a sense of how often that happens. The US research organisation Pew tracked the Google searches of 900 adults in the United States in March 20254. An AI summary appeared on 18% of their searches, rising to 60% for searches written as a question4.

We ran our own check on 8 October 2026. We searched Google from the UK for eight everyday questions, from how a heat pump works to the best CRM for a small business. Seven of the eight searches showed an AI Overview.

The one without was "accountants in Manchester". Google showed a map of local firms and a set of directories instead. That fits a wider pattern: searches looking for a nearby business tend to get local results, while questions get an overview.

The pattern for marketing questions is stronger still. Our research for the AI search page found an AI Overview on almost every marketing search we tested5.

How AI Overviews choose sources

Google says AI Overviews may use a technique it calls query fan-out2. Instead of running one search, the system runs several related searches across subtopics, then writes an answer from what it finds2. While the answer is being written, it can find more pages to link to, which is why the links can be wider and more varied than the normal results2.

To be a link in an AI Overview, a page has to be indexed and eligible to appear in Google Search with a snippet2. Google says there are no extra requirements beyond that2. It also says the overviews rely on its core ranking systems to find relevant, up-to-date pages3.

That does not mean the overview simply copies the top ten results. In our test we could read the sources for six of the overviews. Between them they cited fifty-four pages, and only eleven of those also appeared in the normal results on the same page.

In four of the six searches, none of the cited pages appeared in the normal results at all. For "what is VAT", for example, the overview cited GOV.UK, Wikipedia, Investopedia and three YouTube videos, while the normal results were mostly accountancy firm blogs.

The two searches with real overlap were "what is a limited company" and "how does a heat pump work". In both, official and well-known reference sites such as GOV.UK, Companies House and the Energy Saving Trust ranked in the normal results and were cited in the answer.

Video and forums matter more than many people expect. Twelve of the fifty-four cited pages were YouTube videos, and three more were Reddit threads or a Facebook video. Pew found the same three kinds of site, Wikipedia, YouTube and Reddit, among the most linked sources in AI summaries4.

What we checked	Result
Searches run	Eight, from the UK, on 8 October 2026
Searches showing an AI Overview	Seven
Overviews where we could read the sources	Six
Pages cited in those six overviews	Fifty-four
Cited pages also in the normal results	Eleven
Searches where no cited page was in the normal results	Four
Cited pages that were YouTube videos	Twelve

This was a small test, and the results change from day to day. It still shows the point that matters: ranking on page one and being cited in the overview are related, but they are not the same thing. Closing that gap, with pages that answer each question clearly enough to be quoted, is the focus of our answer engine optimisation service.

AI Overviews, AI Mode and ChatGPT

People often ask whether AI Overviews are the same as ChatGPT. They are not. ChatGPT is a separate assistant made by OpenAI, and you go to it to have a conversation. An AI Overview is a summary Google adds to a normal search, and most people see one without asking for it.

AI Mode is Google's own conversational search. It opens as a separate view where you can ask follow-up questions and get longer answers. Google says AI Overviews and AI Mode may use different models and techniques, so the links they show can differ2. On mobile you can move from an AI Overview into AI Mode to keep asking questions1.

All three draw on the web, so the groundwork that gets you cited is largely shared. Our guide on ChatGPT SEO covers how that assistant finds sources, and our guide to generative engine optimisation covers AI answers in general.

What AI Overviews mean for your traffic

The clearest independent figures come from the Pew study4. When an AI summary appeared, people clicked a normal result on 8% of visits, against 15% when there was no summary4. They clicked a link inside the summary itself on only 1% of visits4.

People were also more likely to stop searching altogether. Browsing sessions ended on 26% of pages with an AI summary, against 16% of pages without one4. In plain terms, the answer on the page was often enough.

Google puts a different emphasis on it. It says clicks from results pages with AI Overviews are higher quality, meaning people are more likely to spend more time on the site they visit2. Both can be true at once: fewer clicks overall, but the people who do click may be further along in their thinking.

What this means for you depends on the searches you rely on.

Simple fact questions. If your traffic comes from questions with a short answer, such as a definition or a rate, expect fewer clicks. The overview often answers the question in full.
Questions that need judgement. Comparisons, costs for your situation and choosing a supplier still need more than a summary. The overview can introduce the topic and send the serious reader on.
Searches for a local business or a named brand. These showed no overview in our test, or a short one. Normal results and the map still do most of the work.

There is also a gain that a traffic report does not show. If your business is named or cited in the overview, a reader sees you before any normal result, even if they never click. For a buyer drawing up a shortlist, that early mention can matter as much as a visit.

Checking whether AI Overviews affect your site

Google counts clicks and impressions from its AI features inside the normal Performance report in Search Console, under the Web search type2. Its newer guidance also points to a generative AI performance report for measuring how your content performs in these features3.

A practical check takes about an hour.

In Search Console, open the Performance report and compare the last three months with the same three months a year earlier.
Sort your queries by impressions and look for ones where impressions held steady or grew while clicks fell. That pattern often points to an answer on the results page.
Search for your ten most valuable questions yourself, from the UK, and note which ones show an AI Overview and whether your site is one of its links.
Keep a short record each month, so you can see whether you are cited more often over time.

Search results differ by location, device and account, so treat any single search as a sample, not a final answer.

Can you turn AI Overviews off?

As a searcher, not fully. Google says its search features cannot be turned off1. You can choose the Web filter under the search box, which shows only text links without features such as AI Overviews1.

As a website owner, you can limit how your content is used, but there is a cost. Google says the controls are the nosnippet, data-nosnippet, max-snippet and noindex settings2. These also limit how your pages appear in normal results, so for most businesses they do more harm than good.

Should you trust what AI Overviews say?

Google itself says AI Overviews can and will make mistakes1. The links are there so you can check the answer against the original page, and for anything important, such as tax, health or legal questions, you should.

For a business, this is a reason to keep the facts about you clear and consistent across your own website and the sites that describe you. An overview can only be as accurate as the pages it reads. Making those facts consistent, on your site and across the web, is a core part of our GEO service.

What to do next

You do not need special files or a new kind of content to appear in AI Overviews. Google says you do not need AI text files or new markup, and that its search does not use them3. The work is the same work that earns good rankings, aimed at being the clearest and most useful page for a question.
