What is zero-click search? A plain-English guide

A zero-click search (also written zero click search) is a Google search that ends without the person clicking on any result. Sometimes the answer was on the results page, sometimes they typed a new search instead, and sometimes they gave up. In SparkToro's June 2026 clickstream study, 68% of US Google searches between January and April 2026 ended this way, and AI Overviews and AI Mode have made the question more pressing for anyone who relies on search traffic.

What counts as a zero-click search

The definition is wider than most people assume. In the 2024 clickstream study SparkToro ran with the panel company Datos, a zero-click search is any search that ends without a click on any result, which covers three different situations:

• Satisfied. The person got what they needed from the results page. Google's own example is "when is the next full moon".
• Frustrated. Nothing looked right, so they left.
• Refined. They changed the search and tried again.

Only the first of those is Google answering the question itself. The other two are as old as search engines, so no single zero-click number tells you how much business you are losing. Every statistic below bundles all three together.

What causes zero-click searches

Google has answered questions on the results page for years; the AI features sit on top of a long list of older ones.

Features that predate AI

• Featured snippets. Boxes where the normal result format is reversed and the descriptive text comes first; they also appear inside "People also ask". You cannot mark a page as a featured snippet. Google's systems decide.
• Knowledge panels and quick facts. Google names the Knowledge Graph and sports scores as answer features where people often read and leave.
• Local results. A search for a business or place nearby shows local results on Maps and in Search, drawn from Business Profiles. Someone can read your hours or call you without visiting your site.
• Google-owned destinations. YouTube, Google Images, Maps, Flights and Hotels take clicks that never reach an independent site. In the 2024 panel study, almost 30% of all clicks from US searches went to Google-owned properties.

AI Overviews and AI Mode

AI Overviews are the generated summaries at the top of some results pages, with links to supporting sites. Google began rolling them out to everyone in the US on 14 May 2024 and started its largest expansion, to more than 100 countries and territories, on 28 October 2024. Google says they appear only when its systems judge them additive to the normal results, and that they "often don't trigger".

AI Mode is a separate tab for a conversational, end-to-end AI search. Google began rolling it out in the US on 20 May 2025 and, on 21 August 2025, said it was live in the US, India and the UK and expanding to more than 180 new countries and territories in English.

Both can use what Google calls query fan-out: the system breaks a question into subtopics, runs many searches at once and builds one response from what it finds. More pages are consulted, but the person sees a single answer, which is why these two features sit at the centre of the zero-click debate.

How common zero-click search is

SparkToro's 2026 study, published on 9 June 2026 and drawn from Similarweb's desktop and mobile clickstream panel, found that 68% of US Google searches between January and April 2026 ended without a click. Two limits apply: it is US-only and covers browser searches only, excluding the Google app. The same study found that only 0.34% of searches went to AI Mode over that period.

The earlier baseline is the 2024 SparkToro and Datos analysis, drawn from a panel of millions of US and EU devices. Its main findings:

• 58.5% of US Google searches and 59.7% of EU Google searches ended with no click at all.
• Searchers ended their session about 37% of the time and changed their query about 22% of the time.
• For every 1,000 US searches, 360 clicks went to the open web, meaning sites Google does not own, excluding ads. In the EU the figure was 374.

The study's author says those figures almost certainly under-count zero-click searches, because they exclude voice-answered searches and searches in the Google app. Separately, the panel had little iPhone coverage at the time.

SparkToro cautions that the 2024 and 2026 studies used different panels, so the two figures are not directly comparable.

Pew Research Center tracked the browsing of 900 US adults through March 2025, covering 68,879 Google searches, and found that about 18% produced an AI summary. Longer and question-shaped searches were far more likely to get one: 60% of searches starting with who, what, when or why, and 53% of searches of ten words or more, against 8% of one- or two-word searches.

Do AI Overviews mean fewer clicks?

On the searches that show them, most independent studies have found fewer clicks, although results vary by method and Google disputes the size of the overall effect.

What the independent studies found

In Pew's March 2025 data, people who saw an AI summary clicked a traditional result on 8% of visits, against 15% when no summary appeared. They clicked a link inside the summary itself on just 1% of visits, and they ended their browsing session more often after seeing one (26% of pages against 16%).

Seer Interactive tracked 3,119 informational queries across 42 of its client organisations from June 2024 to September 2025. In the third quarter of 2025, organic click-through rate was 1.45% where no AI Overview appeared, 0.70% where one appeared and cited the client's brand, and 0.52% where it did not. Seer adds two caveats: it "cannot definitively prove that citation causes higher CTRs", and click-through rate also fell on queries with no AI Overview, from 2.72% in June 2024 to 1.62% in September 2025. Queries that trigger an AI Overview had lower click rates than the rest in every month measured, which Seer reads as the summaries landing on questions people were already answering from the results page. Its April 2026 update found the decline did not extend into 2026: click-through rate on queries with an AI Overview rose from 1.3% in December 2025 to 2.4% in February 2026, still below queries without one, which Seer calls a levelling out rather than a return to earlier rates.

What Google says

Google's Head of Search, Liz Reid, wrote in August 2025 that third-party reports of dramatic declines were inaccurate and often rested on flawed methods or isolated examples:

"Overall, total organic click volume from Google Search to websites has been relatively stable year-over-year."

Google says average click quality has risen too, meaning more clicks where the person does not quickly return to the results, and that people now see more links on the page.

Google also acknowledges the other side. For quick-answer questions, people "may be satisfied with the initial response and not click further", and traffic is moving between sites: towards forums, videos, podcasts and first-hand accounts, and towards in-depth reviews, original posts and first-person analysis.

The fair reading is that fewer people click on quick informational questions than before. Whether your total traffic is down depends on how much of it came from those questions.

Is zero-click search bad for your business?

It depends on what people search for before they buy from you. A plumber or a law firm loses very little when Google answers "how many litres in a gallon" on the page. The searches that matter commercially are the ones where someone compares options, checks prices, reads reviews or looks for a provider nearby, and Google's own account is that people still click through on those to dig deeper or make a purchase.

Before deciding how worried to be, weigh these three points:

• Being seen still counts. A business named in an AI Overview, a local pack or a featured snippet is in front of the buyer without a click, and some of those people will search for the brand later. We have not seen a study that measures this, so treat it as an assumption to test in your own data.
• Local intent still converts on the page. If someone finds your hours, reviews and phone number in the local results and calls you, that is a zero-click search that produced a customer.
• Informational traffic is the exposed part. If a large share of your visits comes from quick definitions, how-to snippets or general articles, that traffic is the most at risk. In Seer's data, about a third of informational queries now show an AI Overview, against 5 to 8% of commercial and transactional ones.

Google's claim that traffic is being redistributed rather than lost rests on internal data that Google has described but not published in detail. Weigh it accordingly.

Zero-click search compared with AI search, AEO and GEO

The terms get mixed up constantly.

• Zero-click search is an outcome: a search that produced no click. You cannot optimise for it directly, only respond to it.
• AI search is a group of products: AI Overviews, AI Mode and chat assistants such as ChatGPT and Gemini. It is one cause of zero-click searches among several.
• AEO, or answer engine optimisation, is the practice of getting your business into the answers those products give. GEO, generative engine optimisation, covers much the same ground with the emphasis on being cited by generative tools. Our beginner's guide to AI SEO explains how AI tools choose which pages to quote.

How to adapt to zero-click search

Adapting is mostly ordinary search work with the priorities shuffled. Google's position is that nothing extra is needed to appear in AI Overviews or AI Mode: a page has to be indexed and eligible to show with a snippet, and "there are no additional technical requirements".

1. Get the fundamentals right

Google's checklist for AI features is the same as for Search generally: crawling allowed in robots.txt and by your CDN or host, pages reachable through internal links, a good page experience, important content in text form, structured data that matches the visible text, and Merchant Center and Business Profile details kept current. Verify the site in Search Console so you see problems early.

2. Answer the quick question, then go past it

If a page only states a fact that a summary can state, people have no reason to click. Put the direct answer at the top, then add what a generated paragraph cannot supply: your own numbers, worked examples, price ranges and a clear recommendation. Google's helpful content guidance asks for original information, research or analysis and insight beyond the obvious, the same first-hand material Google says traffic is moving towards.

3. Let the Business Profile do the selling

For a business with a shopfront or a service area, the Business Profile is the page most people read without ever clicking. Google says local ranking rests on relevance, distance and prominence, and that complete, accurate details (address, hours, category), replies to reviews, and photos all help. A profile that answers "are they open, are they good, how do I reach them" turns zero-click searches into phone calls.

4. Decide deliberately whether to opt out

In 2026 Google added a Search generative AI setting to Search Console, under Settings, that removes your site's links and content from AI Overviews, AI Mode and Discover's generative AI features without affecting your normal listings. Google says it is not a ranking signal for the rest of Search and that changes generally take a few days; Google-Extended remains the separate control for AI model training. The older route, the nosnippet rule, stops Google showing a text snippet from a page anywhere, including AI Overviews and AI Mode, and stops the content being used as a direct input to them, but it also removes the description from your ordinary listing. Either way, opting out means losing the citations and clicks those features send, so check the Generative AI performance report before deciding. For a business that wants to be found, it is rarely the right call.

How to measure zero-click impact

Search Console holds the evidence, once you know how it counts.

• A click is counted only when someone leaves Google for your page; a tap that runs another Google search does not count. Click-through rate is clicks divided by impressions.
• Appearances in AI Overviews and AI Mode are counted inside the normal Performance report under the Web search type. A link clicked inside an AI Overview counts as a click, and the whole AI Overview occupies one position shared by every link in it.
• Since 2026, Search Console has also had a separate Generative AI performance report showing impressions in AI Overviews and AI Mode by page, country, device and date. It reports impressions only, not clicks.

The pattern to watch is impressions steady or rising while clicks fall, concentrated on question-style queries. Compare the last three months with the same period a year earlier, first for queries containing what, how, why or when, then for queries containing your product, service or suburb names. If the first group lost click-through rate and the second did not, informational content is under zero-click pressure while commercial traffic holds. The Generative AI performance report then shows whether the pages that lost clicks are the ones appearing in AI Overviews and AI Mode.

Then follow the click. Google suggests tracking conversions and time on site in Google Analytics alongside Search Console, since fewer clicks that convert beat more clicks that bounce, and watch branded search and direct traffic over the same period.

Common mistakes and myths

• Treating every zero-click search as a lost customer. The definition includes refined and abandoned searches. Only part of it is Google answering instead of you.
• Quoting one statistic as universal. A clickstream panel, a sample of client keywords and Google's internal data measure different things over different periods, and none of them is your site. Date any figure you repeat.
• Blocking Google in a panic. nosnippet removes you from featured snippets and AI answers at once, and even the narrower Search generative AI setting costs you the citations and clicks AI Overviews and AI Mode send.
• Judging informational pages on visits alone. If a page exists to be seen and cited, measure it by impressions and mentions, and keep traffic as the measure for pages built to sell.

Frequently asked questions

Does zero-click search affect Google Ads too?

Partly. Ads still appear in labelled slots, and Google added ads inside AI Overviews for US mobile users in October 2024. Between mid-2024 and September 2025, paid click-through rate on informational queries in Seer's data fell, most sharply where an AI Overview appeared; its 2026 update found paid click-through rate on AI Overview queries had since stabilised. If you bid on broad informational terms, check they still pay.

Are AI Overviews and AI Mode live in Australia and the UK?

Yes. Google began rolling out AI Overviews across Australia on 29 October 2024 and AI Mode in English in Australia on 8 October 2025; AI Mode was live in the UK by August 2025. UK readers can start with our page on AI Overviews SEO in the UK.

Can I stop Google using my content in AI Overviews?

Yes. Search Console's Search generative AI setting removes a site's links and content from AI Overviews and AI Mode without affecting its normal listings; the nosnippet rule does the same page by page but removes your normal snippets too. Step 4 above covers the trade-off.

How to get started

A small business can do the first pass in an afternoon.

1. Run the Search Console comparison above and write down which query groups lost clicks and which did not.
2. Search your ten most important commercial queries from a phone and note what sits above the normal results.
3. Check your Business Profile is verified, complete and current, and reply to the last month of reviews.
4. Take the three informational pages that lost the most clicks. Add a direct answer at the top and, underneath, one thing a summary cannot supply.
