# Featured snippet stats: which numbers are real, and which aren't

## The short answer

Circulating featured-snippet numbers (23.7%, 35%, and 19% prevalence; 41.2% of voice searches) trace to no named, dated source with disclosed methodology. Ahrefs' real 2017 study of 100k keywords found snippets in 12.29% of queries, averaging 8.6% of clicks against 19.6% for the result beneath. Ahrefs' 2025 study shows AI Overviews have since cut snippet visibility 64%.

## Key takeaways

- The commonly cited "23.7% of all search results pages" featured snippet figure traces only to secondary aggregator sites, none of which name a tracker, sample size, or date.
- Ahrefs' real, dated study (29 May 2017, ~100k keywords for CTR, ~14M for prevalence) found featured snippets in 12.29% of queries, not 23.7%, 35%, or 19%.
- That same Ahrefs study found a position-1 featured snippet captured about 8.6% of clicks on average, against 19.6% for the organic result sitting directly beneath it.
- The "41.2% of voice searches return a featured snippet" claim doesn't match Backlinko's real 2018 study: 40.7% of voice answers came from a page that also held a snippet.
- Google's own documentation describes the featured snippet mechanism and opt-out controls but publishes no prevalence or CTR statistic at all.

Search "featured snippet statistics" and the same handful of numbers recur across dozens of posts:
snippets appear in 23.7% of search results, or 35%, or 19%, depending which post you land on;
featured snippet CTR is 35.1%, or an older Ahrefs figure of 8.6%; and 41.2% of voice searches
return a featured snippet. The spread between the low and high prevalence claims is nearly 2x. This
piece traces each number to whatever it claims as a source, keeps the ones that check out, and
drops the ones that don't.

## The prevalence numbers that don't check out

None of 23.7%, 35%, or 19% traces to a named, dated study with disclosed methodology. The 23.7%
figure appears in aggregator posts that cite each other rather than a tracker; one repeats it
alongside a claimed "19.2% in 2025" prior-year figure, also unsourced, that would itself
contradict the unrelated "19%" claim circulating elsewhere as a current number. The 35% figure
turns out to be two different things wearing the same digits: a 35.1% click-share result from a
3,500-respondent self-report survey run by Engine Scout in April 2022, which asked people about
their perceived clicking behavior rather than measuring actual SERP click logs, and a separate,
unrelated Ahrefs data point about one domain's snippet-triggering queries falling 35% in six
months. Neither is a general featured-snippet prevalence rate, and neither matches how it gets
cited. The 19% figure has no disclosed source at all; it does not match either of Ahrefs' two real,
dated prevalence numbers below.

## What Ahrefs actually measured, twice

Ahrefs has published two real, dated, disclosed studies that bracket this topic eight years apart.

**29 May 2017, ~100k keywords for CTR, ~14 million of a 112 million keyword database for
prevalence.** Featured snippets appeared in 12.29% of queries. Where a snippet was present, the
snippet itself captured an average 8.6% of clicks, the organic result sitting directly beneath it
captured 19.6%, and a normal #1 result with no snippet present above it captured 26%. That last
comparison is the study's real finding: a featured snippet did not just add a new result, it took
clicks that would otherwise have gone to position one and redistributed most of them to position
two instead.

**22 July 2025, 1 million randomly selected US desktop SERPs.** Featured snippet visibility fell
from 15.41% in January 2025 to 5.53% in June 2025, a 64% relative decline, correlated at -0.91 with
the growth of AI Overviews over the same window. This is the study that actually answers whether
the 2017 numbers still describe today's SERP: they describe a layout that six in ten of its own
featured-snippet queries no longer produce.

## What Google's own documentation says

[Google's featured-snippet documentation](https://developers.google.com/search/docs/appearance/featured-snippets)
describes the mechanism, not a rate. It states that Google's systems determine algorithmically
whether a page would make a good featured snippet, that a site owner cannot manually mark or
request one, and that a page can opt out entirely with a nosnippet rule or reduce its odds with a
shorter max-snippet setting. No click-through percentage and no share-of-queries statistic appears
anywhere in it. Any claim that attributes a specific CTR or prevalence figure to Google itself is
attributing a number Google has not published.

## The voice search claim, traced

"41.2% of voice searches return a featured snippet" does not match the study it most plausibly
descends from. Backlinko's real, dated voice search study, published 28 February 2018 from an
analysis of 10,000 Google Home results, found that 40.7% of voice search answers came from a page
that also held a featured snippet in desktop search results. That is a narrower and different
claim: it says a correlation existed between a page's featured-snippet status and its odds of being
read aloud by Google Home, not that four in ten voice searches directly surfaced a snippet on
screen. The 41.2% figure appears to be drift from the real 40.7%, close enough to look like a
citation and different enough not to be one.

## Why we care

The through-line across all four unverifiable claims is the same: a real number existed somewhere
in the chain, and repetition sanded off its edges until the source, the date, and the exact
question it answered all fell away, leaving only a percentage that sounds precise enough to trust.
That matters more than usual here because the underlying SERP has genuinely changed: Ahrefs' own
tracking shows featured snippet prevalence fell 64% in the first half of 2025 as AI Overviews
expanded, so a 2017 CTR figure, real or not, describes a search results page that most featured-
snippet queries no longer produce. Publishing a number without its source doesn't just risk being
wrong today; it risks staying uncorrected after the SERP it described has moved on. Anyone citing a
featured-snippet statistic should be able to name the tracker, the sample, and the date, or should
say plainly that no such source could be found.

## Frequently asked questions

### Is the "23.7% of search results have a featured snippet" statistic real?

No named, dated primary source was found for it. It circulates only through secondary SEO blog posts that restate each other, none of which cites a tracker, a sample size, or the study it supposedly came from.

### What is the real featured snippet click-through rate?

Ahrefs' 2017 study of about 100k keywords found the featured snippet itself captured roughly 8.6% of clicks on average, while the organic result directly beneath it captured roughly 19.6%. No comparably disclosed, current study was found to replace this dated figure.

### Does 41.2% of voice searches really return a featured snippet?

No. The real study this likely descends from, Backlinko's 2018 analysis of 10,000 Google Home results, found 40.7% of voice answers came from a page that also happened to hold a featured snippet in desktop search, a correlation, not a direct capture rate, and a different number.

### Has Google ever published its own featured snippet CTR or prevalence number?

Not in its developer documentation. Google describes how featured snippets are selected and how to opt out of them, but does not publish a click-through rate or a percentage of queries that trigger one.
