What Is Zero-Click Search, in Its Defining Sources' Words?
No standards body or search engine defines the term, so the definition comes from the researchers who measure it. SparkToro's 2024 study counted searches that ended “without sending a click anywhere (not even to their own properties or a paid ad)”, and found that “59.7% of European Union Google searches and 58.5% of American Google searches resulted in zero clicks”. Searchers instead “either ended their session entirely (~37% of the time), or changed their search query to something else (~22% of the time)” (SparkToro, 2024).
That is a strict definition: a click on a Google Maps result, a YouTube video or an ad counts as a click. Looser uses of the term, common in marketing writing, count only clicks to the open web, which produces higher figures. When you read a zero-click number, check which definition it uses.

Where the Term Comes From
SparkToro says it “first published research showing that 49% of Google searches ended without a click” in 2019, and that this inspired Amanda Natividad to describe the “Zero Click Web”, “an emerging era of platforms (search engines, social networks, and now AI tools) discouraging users from clicking out” (SparkToro). The 2016 and 2019 figures came from the now-defunct Jumpshot panel, 2024 from Datos (a Semrush company) and 2026 from Similarweb.
The behavior is older than the term. Google said in 2018 that when it introduced featured snippets in January 2014, “there were some concerns that they might cause publishers to lose traffic”. See what a featured snippet is and what a knowledge graph is for two of the features that answer queries on the page.
Percent of Google searches with zero clicks, as reported by SparkToro
Source: SparkToro, “In 2026, Less than One Third of Google Searches Still Send a Click”, June 8, 2026, which gives all four figures and their panels.
SparkToro says this compares “a bit of apples and oranges” because the panels, users and devices differ. Its original July 2024 study reported 58.5% for US searches; the 2026 post gives 60.45% for 2024 without explaining the difference.
What Causes Zero-Click Searches
Several features answer a query before any click. Google's featured snippets show an excerpt first (Google); knowledge panels show facts about entities; and AI Overviews give a generated summary with links. SparkToro attributes the recent rise to “AI features, instant answers, UI elements that keep searchers in the results, and shifting user preferences”, and says AI Overviews appear on “20%+ of all searches” (SparkToro). It also says only 0.34% of searches went on to AI Mode from January to April 2026, so AI Mode was not yet the driver.
Some zero-click searches are simply finished: the searcher wanted a time, a score or a phone number. Others are refinements, where the person searches again. SparkToro's 2026 figures show the share of searchers who perform another search up 7.2 points from 2024. Neither type is a failure of the searcher or the site.
Zero-Click Search and AI Overviews
The clearest recent evidence concerns AI summaries. Pew Research Center tracked 68,879 Google searches by 900 US adults in March 2025 and found that “Users who encountered an AI summary clicked on a traditional search result link in 8% of all visits. Those who did not encounter an AI summary clicked on a search result nearly twice as often (15% of visits)”. Clicks on links inside the summary itself happened “in just 1% of all visits”, and sessions ended on 26% of pages with a summary against 16% without (Pew Research Center).
Ahrefs analyzed 300,000 keywords and found that an AI Overview “correlated with a 34.5% lower average clickthrough rate (CTR) for the top-ranking page, compared to similar informational keywords without an AI Overview” (Ahrefs). Our data report do AI Overviews reduce clicks? compares these studies in detail, and what a Google AI Overview is covers the feature itself.

Pew measures the next page visited, not zero-click searches as SparkToro defines them. Search results were re-collected April 7 to 17, 2025, so summaries may differ from what users saw.
What Google Says
Google disputes the decline in aggregate. Liz Reid, head of Google Search, wrote on August 6, 2025 that “total organic click volume from Google Search to websites has been relatively stable year-over-year”, that Google is sending “slightly more quality clicks” (defined as clicks where users don't quickly click back), and that third-party reports “inaccurately suggest dramatic declines in aggregate traffic” (Google). She also said traffic is shifting between sites, “resulting in decreased traffic to some sites and increased traffic to others.” Google did not publish the data behind these statements. Its AI features guide says “There are no additional requirements to appear in AI Overviews or AI Mode” (Google). Whether Google pays for that use is covered in does Google pay publishers for AI Overviews?
How Zero-Click Search Is Measured
All the public figures come from clickstream panels: people who agree to let software record their browsing. That makes them estimates with known limits.
- Panels differ. SparkToro's series uses three different panels across ten years and says the comparison is “a bit of apples and oranges.”
- Devices are uneven. SparkToro's 2024 study noted “Minimal coverage of mobile iOS devices” and that ad blockers may have depressed paid click figures (SparkToro).
- Definitions differ. Pew counts the next page visited; SparkToro counts any click; keyword studies such as Ahrefs measure click-through rate for a ranking position.
- Your own data is narrower. Search Console shows impressions and clicks for your pages, not searches that never showed you. See what Search Console shows for AI answers.
What Zero-Click Search Means for Brands
If more searches end on the results page, being named there matters even without a visit. The practical responses, none of which is guaranteed, are:
- Measure visibility, not just visits. Track impressions and branded search in Search Console, and referrals from AI tools; see how much traffic AI assistants refer.
- Be the quoted source. Clear, accurate answers on your own pages are what snippets and summaries draw from.
- Be mentioned elsewhere. Independent coverage puts your name in front of people on platforms you do not control; see what earned media is.
- Decide what to allow. Snippet controls limit what Google can show; see how to control snippets and AI Overviews. Restricting snippets can also reduce visibility.
SparkToro's advice is to “Replace traffic as a KPI”; that is one vendor's view, and categories such as branded, local and transactional searches still send clicks by its own account.

Common Misconceptions About Zero-Click Search
| Myth | What the source actually says | Source |
|---|---|---|
| Zero-click means Google sent no one anywhere | SparkToro's strict measure counts clicks to Google properties and ads as clicks; zero-click means none of these | SparkToro |
| All zero-click figures measure the same thing | Pew, SparkToro and Ahrefs use different panels and definitions | Pew; Ahrefs |
| AI Mode is causing the rise | SparkToro: only 0.34% of searches went to AI Mode, January to April 2026 | SparkToro |
| Google agrees clicks are falling | Google says organic click volume is “relatively stable”, without publishing data | |
| Zero-click search makes websites pointless | Answers on the results page are often drawn from websites; Google's featured snippets quote pages directly |
Frequently Asked Questions
What is a zero-click search in simple terms?
It is a search where the person does not click any result. They either got their answer on the results page, searched again, or gave up.
What percentage of Google searches are zero-click?
SparkToro, using Similarweb panel data, reported 68.01% for the first four months of 2026. For 2024 the same post gives 60.45% for US searches; SparkToro's original 2024 study, on the Datos panel, reported 58.5%. Figures vary by panel and definition.
Do AI Overviews cause zero-click searches?
They are associated with fewer clicks. Pew found users clicked a traditional result in 8% of visits with an AI summary against 15% without. Google says overall organic click volume is relatively stable.
Is zero-click search bad for my business?
It can reduce visits for questions answered on the page, but your brand may still be seen or quoted. Branded, local and transactional searches still tend to send clicks.
How can I measure zero-click impact on my site?
Compare impressions and clicks in Search Console over time and watch click-through rate for informational queries. You cannot see searches where your page never appeared.
Does Google define zero-click search?
No. The term comes from marketing researchers such as SparkToro. Google discusses click volume and click quality instead.
