Search Engine Statistics 2026: Market Share, Search Volume and AI Summaries

Google holds the large majority of search-engine share worldwide: 89.94% in StatCounter’s all-platform snapshot for September 2026. Google has also said it sees more than 5 trillion searches a year, a figure it published on May 21, 2025. On clicks, a Pew Research Center study of U.S. adults found that people clicked traditional search results less often when Google displayed an AI summary. Each of these numbers counts something different, so the sections below keep their denominators separate.

Google’s share of worldwide search

StatCounter’s Search Engine Market Share page, in its worldwide, all-platform view, lists these shares for September 2026:

Search engine Share, worldwide, all platforms, September 2026
Google 89.94%
Bing 5.29%
Yahoo! 1.36%
Yandex 1.30%
DuckDuckGo 0.74%
Baidu 0.44%

Source: StatCounter Global Stats, Worldwide Search Engine Market Share, September 2026 snapshot. Together the six engines in the table account for 99.07% of the total; the remainder is split among other engines.

These are percentage estimates from StatCounter’s measurement. They describe each engine’s estimated share of search as StatCounter records it. They are not a count of queries, and the worldwide view blends every device and country into one number. StatCounter also publishes desktop, mobile, tablet, regional and historical views, which can look very different from the headline figure.

Why the blended figure hides device and country differences

A worldwide percentage averages markets that behave differently. The search statistics compilation at SQ Magazine (dated August 4, 2026) reports the following splits for April 2026:

Search engine Desktop, April 2026 Mobile, April 2026
Google 83.5% 95.52%
Bing 10.35% 1.27%

The same compilation names country exceptions: Yandex leads in Russia, and Baidu leads in China. Bing’s 5.29% worldwide figure says little about its desktop position, which this compilation places at more than eight times its mobile share.

These device and country figures come from a secondary page rather than from StatCounter’s own regional or platform tables, so treat them as indicative. Check the live StatCounter views for the device and country you are writing about before quoting a specific value.

How many searches Google handles

The official annual figure

In a May 21, 2025 post on Google’s business blog, “New ways AI in Search helps your business”, the company wrote: “We already see more than 5 trillion searches on Google annually.” This is a company-reported figure. The post gives no counting method and no engine-by-engine comparison, and a newer official total is not available in the sources cited here. Read “more than 5 trillion” as a May 2025 statement, not a 2026 measurement.

What a per-day figure would and would not mean

Dividing 5 trillion by 365 gives about 13.7 billion searches per day. This is an arithmetic average derived from Google’s rounded annual statement, not a daily count Google has published. Because the statement says “more than,” 13.7 billion is best read as a floor for the average day, and it says nothing about any single day, which varies with the calendar and with news cycles.

No comparable recent query volume is established for Bing, Yahoo!, Yandex, DuckDuckGo or Baidu. Query volume therefore cannot be converted into a share of all searches, and the share figures above cannot be divided into a volume figure.

How often AI Overviews and AI summaries appear

Prevalence depends mostly on which queries are sampled. Two recent studies show how wide the range can be:

Study Sample and period Searches showing an AI summary
Pew Research Center, published July 22, 2025 Google searches run by 900 U.S. adults in a tracked browsing panel, March 1–31, 2025; 68,879 unique searches, with results scraped April 7–17, 2025 About 18% of searches produced an AI summary
Haofei Xu, Umar Iqbal and Jacob M. Montgomery, arXiv preprint, May 13, 2026 55,393 trending queries across 19 topics, March 13–April 21, 2026 13.7% overall; 64.7% of question-form queries

The two sets of figures differ because their samples differ, and their dates differ too, so the gap cannot be read as a change over time. Pew measured searches that panel members ran, while the preprint sampled trending queries and found that question-form phrasing triggered AI Overviews far more often. Do not average the two into a single prevalence rate.

The preprint, “Measuring Google AI Overviews: Activation, Source Quality, Claim Fidelity, and Publisher Impact” (arXiv:2605.14021), has not completed journal peer review. It also reports that 11.0% of the individual claims it examined within AI summaries were not supported by the pages cited for them. That measures the accuracy of cited sources rather than how often people click, so it belongs in a separate category from the prevalence figures.

Do people click links when an AI summary appears?

What Pew observed

Pew Research Center’s report, “Google users are less likely to click on links when an AI summary appears in the results”, published July 22, 2025, found:

  • When an AI summary appeared, people clicked traditional search result links in 8% of visits. Without one, the rate was 15%, so the click rate was roughly half as high.
  • Links inside the AI summary itself were clicked in 1% of visits to pages that showed one.
  • The data cover 900 U.S. adults in a tracked panel, March 2025, and Google searches only. The rates are per visit, not per search.

This is an observational result for one panel and one month. It does not show that the same gap exists in other countries, on other engines, or under later versions of Google’s results page.

Google’s account

In an August 6, 2025 post, “AI in Search is driving more queries and higher quality clicks”, Liz Reid, VP and Head of Google Search, wrote that “total organic click volume from Google Search to websites has been relatively stable year-over-year,” and that Google was sending “slightly more quality clicks to websites than a year ago.” These statements come from Google’s internal data, and no independent measurement is attached to them.

The two accounts can both be true because they measure different things. Pew reports the share of tracked visits that end in a click on a traditional result. Google reports total organic clicks across its own traffic. A stable total can coexist with fewer clicks per tracked visit if the number of visits grows. Neither account shows how that balance plays out for a specific website.

Traffic shares to websites are not search shares

DataReportal’s Digital 2026 Mid-Year Global Update cites Similarweb data on traffic across the top 10,000 domains. These figures measure where visits to websites go, not who runs searches:

Period Google.com share of traffic ChatGPT.com share of traffic
June 1–August 31, 2025 19.56% 1.33%
December 1, 2025–February 28, 2026 19.79% 1.32%

ChatGPT.com’s figures are website traffic shares, not search-engine market shares, and they should not be read as a count of the searches ChatGPT receives.

Checks before you quote a search statistic

  • Geography: worldwide, a single country, or a region.
  • Device: all platforms, desktop, mobile or tablet.
  • Period: a monthly snapshot, a calendar-year statement, or a fixed study window.
  • Unit: share of search engine usage, a count of queries, a share of website traffic, or clicks per visit.
  • Sample: all of a company’s searches, a panel of adults, or a set of trending or question-form queries.

The Bottom Line

The most current answer to “what share does Google have” is StatCounter’s worldwide figure for September 2026, read with its scope intact. Every other number here answers a narrower question, and each one is only accurate when it is cited alongside that question.
