177 Search Engine Statistics for 2026

Google held 91.05% of the worldwide search engine market in October 2026 and 85.45% in the United States, on StatCounter's measure of search referrals. Google itself says it sees more than 5 trillion searches a year, and Alphabet reported $224,532 million of "Google Search and other" revenues for 2025.

What happens after the search is changing. SparkToro's panel study finds 68.01% of US Google searches ended without a click in January-April 2026, and Google says AI Overviews had over 2.5 billion monthly active users in May 2026. Studies disagree on how often AI Overviews appear and on what they do to clicks, so each one is shown here with its producer, base and date.

Every figure below links to the primary source that printed it. Tracker shares, company accounts, court findings, regulator decisions and vendor studies measure different things and are kept apart.

Which search engine has the biggest market share worldwide?

Google, by a wide margin on both measures shown here. The trackers differ on the decimals because each one counts referrals on its own network of sites, so read each figure with its producer.

  1. 1 Google 91.05%
  2. 2 Bing 4.8%
  3. 3 Yahoo! 1.18%
  4. 4 Yandex 1.14%
  5. 5 DuckDuckGo 0.64%
  6. 6 Baidu 0.42%
Worldwide search engine market share in October 2026 on StatCounter's measure, all devices. StatCounter tracks search referrals to sites that carry its tracking code, so this is not a share of searches made. (StatCounter (worldwide search share), Oct 2026)
  • Behind Google in October 2026, StatCounter puts Bing at 4.8% of the worldwide search engine market, Yahoo! at 1.18%, Yandex at 1.14%, DuckDuckGo at 0.64% and Baidu at 0.42% (all devices). (StatCounter (worldwide search share), Oct 2026)
  • StatCounter's yearly figure for Google worldwide was 89.91% for 2025, against 90.67% for 2024 and 92.38% for 2023 (all devices). (StatCounter (worldwide search share), 2025)
  • On the same yearly measure Bing went from 2.97% worldwide in 2023 to 3.74% in 2024 and 4.02% in 2025, and Yandex from 1.35% to 1.94% and 2.24%. (StatCounter (worldwide search share), 2025)
  • On Cloudflare's network, Google referred "nearly 90%" of search engine traffic to customer sites worldwide in 2025. Bing referred 3.1%, Yandex 2.0%, Baidu 1.4% and DuckDuckGo 1.2%. (Cloudflare (Radar Year in Review 2025), Dec 2025)

StatCounter and Cloudflare are different producers with different networks and periods. StatCounter's figures are its own measure from its tracker network; Cloudflare's come from the referer header on requests to its customers' sites. Neither is a share of queries, and the two should not be merged.

How does search engine share differ between desktop and mobile?

  • On desktop worldwide in October 2026, StatCounter puts Google at 77.93%, Bing at 15.03%, Yahoo! at 3.32%, Yandex at 1.48%, DuckDuckGo at 0.93% and Baidu at 0.35%. (StatCounter (search share by device), Oct 2026)
  • On mobile worldwide in October 2026, StatCounter puts Google at 96.35%, Yandex at 1.01%, Bing at 0.61%, DuckDuckGo at 0.53%, Baidu at 0.45% and Yahoo! at 0.36%. (StatCounter (search share by device), Oct 2026)
  • On Cloudflare's network in 2025, Google's share of search referrals from desktop systems worldwide was about 80% and Bing's nearly 11%. On Windows, Google referred 76% and Bing about 14%. On mobile devices Google held almost 93%. (Cloudflare (Radar Year in Review 2025), Dec 2025)

What is Google's share of search in the United States?

Lower than its worldwide share on the tracker data, and still far ahead of everyone else. Bing does better in the US than elsewhere, and almost all of that is on desktop.

  • Behind Google in the United States in October 2026, StatCounter puts Bing at 9.78%, Yahoo! at 2.54%, DuckDuckGo at 1.74%, Yandex at 0.32% and Ecosia at 0.11% (all devices). (StatCounter (US search share), Oct 2026)
  • StatCounter's yearly figure for Google in the United States was 86.16% for 2025, against 87.89% for 2024. Bing went from 7.27% to 7.94% and DuckDuckGo from 1.98% to 2.32%. (StatCounter (US search share), 2025)
  • On US desktops in October 2026, StatCounter puts Google at 74.86%, Bing at 18.8%, Yahoo! at 3.98% and DuckDuckGo at 1.96%. (StatCounter (US search share), Oct 2026)
  • On US mobile devices in October 2026, StatCounter puts Google at 94.12%, Bing at 2.26%, DuckDuckGo at 1.53% and Yahoo! at 1.51%. (StatCounter (US search share), Oct 2026)
  • Measured by query volume, the court found Google's share of US general search rose to 94.9% on mobile devices in 2020, against Bing's 5.5% of all queries and 1.3% on mobile. Google's share had been 80% in 2009 (opinion of 5 August 2024). (US District Court, D.D.C. (United States v. Google LLC, liability opinion), Aug 2024)
  • The court found that Google receives nine times more search queries each day than all of its rivals combined across all devices in the United States, and nineteen times more on mobile (opinion of 5 August 2024, trial record). (US District Court, D.D.C. (United States v. Google LLC, liability opinion), Aug 2024)
  • Counting searches made on 41 major sites, SparkToro found Google handled 73.7% of all US desktop searches in Q4 2025. About 80% of desktop searches happened on traditional search engines, about 10% on commerce sites, about 5.5% on social networks and 3.2% on AI tools (Datos desktop panel). (SparkToro (41 search sites study), Mar 2026)

Three different measures appear here. StatCounter counts search referrals on its tracker network. The court's figures are shares of general search engine queries from the trial record. SparkToro counts searches typed into 41 sites, including shops and social networks, on a desktop panel. They are not comparable.

How does search engine market share vary by country?

Google leads in the UK, Germany and India on the tracker data, but not everywhere. Yandex is ahead in Russia, Naver runs Google close in South Korea, and Bing takes a large slice in Japan on the tracker data.

  1. 1 Baidu 49%
  2. 2 Bing 21.69%
  3. 3 Yandex 11.77%
  4. 4 Haosou 8.67%
  5. 5 Google 6.83%
  6. 6 Sogou 1.72%

  • In the United Kingdom in October 2026, StatCounter puts Google at 90.59%, Bing at 6.76%, Yahoo! at 1.37%, DuckDuckGo at 0.7%, Ecosia at 0.31% and Yandex at 0.24% (all devices). (StatCounter (search share by country), Oct 2026)
  • In StatCounter's Europe region, which is not the same as the EU, Google had 88.77% in October 2026, Bing 5.58%, Yandex 2.5%, Yahoo! 1.51%, DuckDuckGo 0.77% and Ecosia 0.47% (all devices). (StatCounter (search share by country), Oct 2026)

  • In India in October 2026, StatCounter puts Google at 98.06%, Bing at 1.11%, Yahoo! at 0.35% and DuckDuckGo at 0.33% (all devices). (StatCounter (search share by country), Oct 2026)
  • In the Russian Federation in October 2026, StatCounter puts Yandex at 70.22%, Google at 28.36% and Bing at 0.82% (all devices). (StatCounter (search share by country), Oct 2026)
  • In the Republic of Korea in October 2026, StatCounter puts Google at 48.48%, Naver at 42.25% and Bing at 4.94% (all devices). (StatCounter (search share by country), Oct 2026)
  • In Japan in October 2026, StatCounter puts Google at 59.34%, Bing at 32.51% and Yahoo! at 6.56% (all devices). (StatCounter (search share by country), Oct 2026)
  • On Cloudflare's network in 2025, Yandex held a 65% share of search referrals in Russia against Google's 34%. In the Czech Republic Google had 84% and the local engine Seznam 7.7%. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • The CMA found that Google has held over 90% of queries among traditional general search providers in the UK for at least fifteen years, and that in each year from 2009 to 2019 it generated more than 90% of UK search traffic and of UK search advertising revenues (decision of 10 October 2025). (CMA (Google general search SMS decision), Oct 2025)

StatCounter's and Cloudflare's figures for Russia come from different networks and periods and are not the same measure. The CMA's finding is a share of queries, which is a different basis again.

How much is Google Search used?

Google publishes a yearly search total and occasional milestones, not a daily count. Every figure in this section is Google's own statement unless it is labelled as a court finding.

  • Google said in 2017 that 15 percent of the searches it sees every day are new, and that around 0.25 percent of queries in its daily traffic had been returning offensive or clearly misleading content (worldwide, Google's own statement). (Google (2017 Search quality post), Apr 2017)

  • Google says it has cut Search latency by more than 35% over the past five years, and cut the cost of core AI responses by more than 30% since moving AI Overviews and AI Mode to Gemini 3 (April 2026). (Google (Q1 2026 earnings remarks), Apr 2026)
  • Google says Circle to Search was available on over 580 million Android devices in February 2026. The count is of devices, not users. (Google (Q4 2025 earnings remarks), Feb 2026)
  • The court found that Google's top five queries by volume are navigational, and that nearly 12% of all Google queries are navigational (US trial record, opinion of 5 August 2024). (US District Court, D.D.C. (United States v. Google LLC, liability opinion), Aug 2024)
  • The court found that 80% of Google's queries are noncommercial, meaning Google does not try to show a search advertisement against them (US trial record, opinion of 5 August 2024). (US District Court, D.D.C. (United States v. Google LLC, liability opinion), Aug 2024)

Google gives its search total per year. This page does not convert it to a daily figure.

How many people use AI Overviews and AI Mode?

  • Google said in April 2025 that AI Overviews had over 1.5 billion users per month (Google's own count, worldwide). (Google (Q1 2025 earnings remarks), Apr 2025)
  • Google said in July 2025 that AI Overviews had over 2 billion monthly users across more than 200 countries and territories and 40 languages (Google's own count). (Google (Q2 2025 earnings remarks), Jul 2025)
  • Google said in July 2025 that AI Mode had over 100 million monthly active users in the US and India (Google's own count). (Google (Q2 2025 earnings remarks), Jul 2025)
  • Google said in October 2025 that AI Mode had over 75 million daily active users after its worldwide rollout (Google's own count). (Google (Q3 2025 earnings remarks), Oct 2025)
  • Google said in May 2026 that AI Mode had passed 1 billion monthly active users within a year of launch (Google's own count, worldwide). (Google (I/O 2026 keynote), May 2026)

The AI Mode figures count different things: monthly users in two countries, then daily users worldwide, then monthly users worldwide. They are milestones and not a like-for-like series.

How much revenue does search advertising generate?

Hundreds of billions of dollars a year on Alphabet's own accounts, and the line grew again in 2025 and 2026. Microsoft reports growth in search advertising too, but gives a rate and not a comparable total.

  • Alphabet reported $198,084 million for "Google Search and other" in 2024, and says in its 2025 annual report that these revenues increased $26.4 billion from 2024 to 2025 (worldwide, the firm's own figures). (Alphabet (Form 10-K 2025), Feb 2026)
  • Alphabet's total revenues were $402,836 million in 2025. Google advertising in total was $294,691 million, of which YouTube ads were $40,367 million and Google Network $29,792 million (the firm's own figures). (Alphabet (Form 10-K 2025), Feb 2026)
  • Google's traffic acquisition costs, the payments it makes to distribution partners and Network partners, were $59,926 million in 2025, up from $54,900 million in 2024. The rate fell from 20.7% to 20.3% of Google advertising revenues (Alphabet's own figures). (Alphabet (Form 10-K 2025), Feb 2026)

  • The court found that Google booked nearly $47 billion in advertising revenue in 2014 and over $146 billion in 2021, and that Bing generated less than $12 billion in 2022 (opinion of 5 August 2024). (US District Court, D.D.C. (United States v. Google LLC, liability opinion), Aug 2024)

The court's advertising figures and Alphabet's reported line are close but not identical, so each is kept with its source.

How big is search advertising in the US and the UK?

The US and UK figures come from two separate trade body studies in different currencies and should not be added together. The US report prints search and social media as separate lines; this page does not rank one against the other.

How much does Google pay to be the default search engine?

Tens of billions of dollars a year, according to the US court that ruled on those contracts. The findings show why it pays: most searches start wherever the default sends them.

  1. 1 Google-Apple agreement 28%
  2. 2 Android device makers and carriers 19.4%
  3. 3 Third-party browsers 2.3%
Share of all US general search queries that flow through access points covered by the Google default contracts at issue in the case, by type of agreement, as found by the court in United States v. Google LLC (opinion of 5 August 2024). The three rows are percentages of all US queries. (US District Court, D.D.C. (United States v. Google LLC, liability opinion), Aug 2024)

The court's revenue share figure covers default distribution contracts. It is not the same line as the traffic acquisition costs Alphabet reports, which also include payments to Network partners.

What have UK and EU authorities decided about Google Search?

  • The CMA found that Google earned at least £3-4 billion of profits in 2024 from its UK general search services over and above a normal return on capital (decision of 10 October 2025). (CMA (Google general search SMS decision), Oct 2025)
  • Of the European Commission's fine of 23 July 2026, €460 million was for self-preferencing Google's own services in Google Search and €430 million for anti-steering rules on Google Play. The decisions give Google 60 days to comply or risk periodic penalty payments of up to 5% of its worldwide turnover. (European Commission (DMA decisions on Google), Jul 2026)
  • On 10 September 2024 the Court of Justice of the EU upheld the fine of €2,424,495,000 imposed on Google in 2017 for favouring its own comparison shopping service in general search results in 13 EEA countries. (Court of Justice of the EU (Google Shopping judgment), Sep 2024)

How many Google searches end without a click?

Most of them. SparkToro titled its 2026 study on the finding that less than one third of Google searches still send a click, and a second producer with its own panel reports a higher share still.

  1. 1 United Kingdom 69.5%
  2. 2 United States 68.0%
  3. 3 France 65.3%
  4. 4 Canada 63.8%
  5. 5 Italy 63.4%
  6. 6 Germany 62.1%

  • Only 0.34% of US Google searches led to AI Mode in January-April 2026, on SparkToro's analysis of Similarweb's panel. (SparkToro (zero-click study 2026), Jun 2026)
  • Of the six countries SparkToro compared for January-April 2026, the zero-click share of Google searches was highest in the United Kingdom at 69.5% and lowest in Germany at 62.1% (Similarweb's panel). (SparkToro (zero-click by country), Jun 2026)
  • First Page Sage, on its own panel and crawl, puts the share of US Google searches that end without a click at 74.2% in its September 2026 report, up from 64.8% a year earlier. (First Page Sage (CTR by position 2026), Sep 2026)
  • Total visits to the web's top million sites peaked at 2.243 trillion in Q1 2022 and stood at 1.970 trillion in Q3 2026, down 12.2%, on SparkToro's analysis of Similarweb's worldwide panel. The count covers all traffic and is not limited to search referrals. (SparkToro (open web traffic study), Nov 2026)
  • In the same study, visits per web user fell 29.2% as the number of web users grew from 4.95 billion to 6.15 billion. (SparkToro (open web traffic study), Nov 2026)
  • 96.55% of pages in Ahrefs' index of about 14 billion pages get zero traffic from Google, and 1.94% get between one and ten monthly visits, on Ahrefs' own traffic estimates from its 2023 study. (Ahrefs (search traffic study), Dec 2023)

SparkToro and First Page Sage are separate measures on different panels and should not be compared or averaged. SparkToro's 2024 comparison uses a different panel from its 2026 figure, and SparkToro says so itself.

How often do AI Overviews appear in Google results?

It depends on who is counting and which searches or keywords they count. The five producers below use different keyword sets, bases and dates, and their shares are far apart.

  • 18% of Google searches made by a panel of US adults in March 2025 produced an AI summary, and 58% of the panel ran at least one search that did, in Pew Research Center's study. (Pew Research Center (AI summaries study), Jul 2025)
  • In Semrush's own keyword dataset (10M+ keywords), AI Overviews were triggered for 6.49% of queries in January 2025, 24.61% in July 2025 and 15.69% in November 2025. (Semrush (AI Overviews study), Dec 2025)
  • In seoClarity's keyword database, AI Overviews appeared for 30% of US desktop keywords in September 2025, against 10% in March 2025. (seoClarity (AI Overviews research), Oct 2025)
  • Similarweb puts the AI Overview appearance rate in the US at 43%+, without stating a month or a base. (Similarweb (AI Search Stats 2026), Jul 2026)
  • First Page Sage reports that an AI-generated answer, meaning an AI Overview or an AI Mode response, appeared on 81.6% of US Google queries in September 2026, up from 23.4% in September 2025 (its own panel and crawl). (First Page Sage (CTR by position 2026), Sep 2026)

These five figures are not comparable and none is the definitive share. Pew counts searches made by a panel of US adults. Semrush and seoClarity count keywords in their own databases. Similarweb gives no month or base. First Page Sage counts AI Overviews and AI Mode responses together on its own query sample.

Which searches trigger an AI Overview?

  • In Pew's US panel in March 2025, 8% of one- or two-word Google searches produced an AI summary against 53% of searches with 10 or more words. The share was 60% for searches beginning with a question word and 36% for searches containing both a noun and a verb. (Pew Research Center (AI summaries study), Jul 2025)
  • In Semrush's own keyword dataset, informational queries fell from 91.3% of the queries that trigger an AI Overview in January 2025 to 57.1% in October 2025. (Semrush (AI Overviews study), Dec 2025)
  • In seoClarity's US keyword database, AI Overviews for transactional keywords rose to 12.54% in September 2025, while AI Overviews for local keywords fell to 0.01%. (seoClarity (AI Overviews research), Oct 2025)
  • In Semrush's own keyword dataset of 400 commercial-modifier keywords in banking, ecommerce and software, AI Overview coverage reached 88% in August 2026, up from 45.75% in September 2025. (Semrush (commercial modifiers study), Oct 2026)
  • In the same Semrush keyword set, AI Overview coverage of ecommerce queries rose from 32.62% to 85.11%, and "best X for Y" searches reached 96.12%. (Semrush (commercial modifiers study), Oct 2026)

Which sources do AI Overviews cite?

  • 88% of the Google AI summaries in Pew's US study cited three or more sources, and the median summary was 67 words long (searches made in March 2025). (Pew Research Center (AI summaries study), Jul 2025)
  • Wikipedia, YouTube and Reddit together made up 15% of the sources cited in Google AI summaries and 17% of sources in standard results in Pew's US study. 6% of AI summary sources were .gov sites, against 2% in standard results. (Pew Research Center (AI summaries study), Jul 2025)
  • 97% of Google AI Overviews cite at least one source from the top 20 organic results, and each AI Overview includes on average five URLs from those results, in seoClarity's analysis of 432,000 keywords. (seoClarity (AI Overviews research), Oct 2025)

Do AI Overviews reduce clicks to websites?

Two outside studies find fewer clicks, one finds the zero-click rate went down, and Google points to more queries. The designs differ too much to settle the question here, so each finding is given with its method.

  1. 1 Position 1 -58.0%
  2. 2 Position 2 -50.8%
  3. 3 Position 3 -46.4%
  4. 4 Position 4 -38.8%
  5. 5 Position 5 -32.6%
  6. 6 Position 6 -30.5%
  7. 7 Position 7 -29.7%
  8. 8 Position 8 -28.8%
  9. 9 Position 9 -29.7%
  10. 10 Position 10 -19.4%
Estimated change in click-through rate when an AI Overview is present, by organic position, in Ahrefs' study on December 2025 data (300,000 keywords, desktop). The figures are correlations from one vendor's sample, not a controlled experiment. (Ahrefs (AI Overviews click study), Feb 2026)
  • US Google users who saw an AI summary clicked a traditional search result in 8% of visits, against 15% of visits for those who did not, in Pew's panel study of March 2025. A link inside the AI summary was clicked in 1% of visits. (Pew Research Center (AI summaries study), Jul 2025)
  • In the same Pew study, US Google users ended their browsing session after 26% of search pages with an AI summary, against 16% of pages with only traditional results. (Pew Research Center (AI summaries study), Jul 2025)
  • Ahrefs found that the presence of an AI Overview correlates with a 58% lower average click-through rate for the top-ranking page on December 2025 data, up from the 34.5% reduction it found in April 2025 (300,000 keywords, desktop click-through rate). (Ahrefs (AI Overviews click study), Feb 2026)
  • Around 9% of AI Overviews appear outside position one on the results page, in the same Ahrefs study. (Ahrefs (AI Overviews click study), Feb 2026)
  • In Semrush's own keyword dataset, the zero-click rate for the same keywords went from 33.75% before they started showing an AI Overview to 31.53% after (over 200,000 keywords, January-October 2025, Datos clickstream data). (Semrush (AI Overviews study), Dec 2025)
  • Google says AI Overviews drive over 10% more queries worldwide for the types of queries that show them. This is Google's own claim and it concerns query volume, not clicks to websites. (Google (Q2 2025 earnings remarks), Jul 2025)
  • On US Google results pages with an AI answer, 51.0% of clicks went to a citation link, in First Page Sage's own data for 2026. (First Page Sage (CTR by position 2026), Sep 2026)
  • First Page Sage puts the click-through rate of the first source cited in a Google AI answer at 5.2% (39.7% of all AI answer clicks), the second at 3.1% (23.7%), the third at 1.9% (14.5%), the fourth at 1.2% (9.2%) and the fifth at 0.8% (6.1%), in its own US data for 2026. (First Page Sage (CTR by position 2026), Sep 2026)

These findings are not comparable. Pew observes clicks by a panel of US adults. Ahrefs compares actual with forecast desktop click-through rates for keywords. Semrush compares zero-click rates for the same keywords before and after an AI Overview appeared and does not state a country. Google's statement is about query volume. This page does not rule between them.

What do news publishers expect from search traffic?

  • News publishers expect traffic from search engines to fall by 43% over the next three years, in the Reuters Institute's survey of 280 digital news leaders in 51 countries and territories (268 answered this question). This is an expectation, not measured traffic. (Reuters Institute (Trends and Predictions 2026), Jan 2026)
  • In the same survey, the net score for effort planned on "old-style search optimisation" was -25 points, against +61 for distribution via AI chatbots. (Reuters Institute (Trends and Predictions 2026), Jan 2026)

What is the click-through rate of the top Google result?

There is no single answer. Three producers publish a position-one figure, and each uses its own data, definition and period, so the numbers below cannot be lined up against each other.

  1. 1 Position 1 7.1%
  2. 2 Position 2 3.0%
  3. 3 Position 3 1.7%
  4. 4 Position 4 1.1%
  5. 5 Position 5 0.7%
  6. 6 Position 6 0.6%
  7. 7 Position 7 0.4%
  8. 8 Position 8 0.3%
  9. 9 Position 9 0.2%
  10. 10 Position 10 0.2%
US Google click-through rate by organic position in 2026, blended across pages with and without an AI answer, in First Page Sage's own data (1,184 domains, March-August 2026). This is one firm's panel and is not comparable with the Backlinko or Ahrefs figures. (First Page Sage (CTR by position 2026), Sep 2026)
  • Backlinko's study of about 4 million Google results puts the average click-through rate of the number one organic result at 27.6%, and finds it 10x more likely to be clicked than the number ten result. The page was last updated in 2025 and gives no collection period. (Backlinko (CTR study), Apr 2025)
  • First Page Sage puts the US click-through rate of organic position one at 7.1% in 2026, blended across pages with and without an AI answer: 3.6% when an AI answer is present and 22.6% when it is not. Its blended figure was 39.8% in its 2025 report (1,184 domains, March-August 2026). (First Page Sage (CTR by position 2026), Sep 2026)
  • Ahrefs, which prints click-through rate as a fraction, found the average position-one rate for informational keywords fell from 0.076 in December 2023 to 0.039 in December 2025. For keywords that show an AI Overview it fell from 0.073 to 0.016 (aggregated Google Search Console desktop data). (Ahrefs (AI Overviews click study), Feb 2026)

The Backlinko, First Page Sage and Ahrefs figures are not comparable. Backlinko uses Search Console data supplied by its owner Semrush, organic results only, with no stated period or country. First Page Sage uses its own client and panel domains in the US. Ahrefs uses desktop data for chosen keyword groups.

How do clicks fall away below position one?

  • In Backlinko's study, the top 3 Google results get 54.4% of all clicks, and 0.63% of searchers clicked a result on the second page. (Backlinko (CTR study), Apr 2025)
  • In Backlinko's study, moving up one position in Google raises absolute click-through rate by an average of 2.8% and relative click-through rate by 32.3%. Moving from number two to number one gives 74.5% more clicks, and moving from number ten to number nine gives 11% more. (Backlinko (CTR study), Apr 2025)
  • First Page Sage puts the US click-through rate of local pack positions one to three at 14.8%, 12.6% and 11.9%, and of the featured snippet at 11.4%, in its own data for 2026. (First Page Sage (CTR by position 2026), Sep 2026)

What makes a result more likely to be clicked?

  • In Backlinko's study, title tags of 40 to 60 characters have a 33.3% higher click-through rate than titles outside that range, and titles with a positive sentiment improve it by about 4%. (Backlinko (CTR study), Apr 2025)
  • In the same study, keywords of 10-15 words get 1.76x more clicks than single-word terms, and URLs containing terms similar to the keyword have a 45% higher click-through rate. (Backlinko (CTR study), Apr 2025)

These are correlations in one vendor's sample, not tested causes.

How much web traffic comes from search and AI crawlers?

A lot. On Cloudflare's network, bots request nearly as many pages as people do. AI crawlers take far more pages than they send visitors back, on Cloudflare's own ratio.

  1. 1 Oceania 54.2%
  2. 2 Europe 48.6%
  3. 3 North America 45.5%
  4. 4 South America 44.2%
  5. 5 Asia 39.0%
  6. 6 Africa 35.8%
Googlebot's share of AI and search crawler traffic to Cloudflare customer sites by world region, October 2025. Cloudflare assigns a site to a region by its customer's billing address. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • Googlebot was responsible for over 28% of traffic from Verified Bots on Cloudflare's network in 2025. OpenAI's GPTBot originated about 7.5% and Microsoft's Bingbot 6% (worldwide). (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • Search engine crawlers were responsible for 40% of Verified Bot traffic on Cloudflare's network in 2025, AI crawlers for 20% and SEO bots for over 13%. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • AI bots accounted for an average of 4.2% of HTML requests across Cloudflare's customer base in 2025, while Googlebot alone originated 4.5%. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • As of 2 December 2025, humans generated 47% of HTML requests on Cloudflare's network and non-AI bots 44%. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • Cloudflare says Anthropic had the highest crawl-to-refer ratios in 2025, reaching as much as 500,000:1 and later ranging from about 25,000:1 to 100,000:1. Perplexity generally stayed below 400:1 and Microsoft peaked in the 50:1 to 70:1 range. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • Google's crawl-to-refer ratio on Cloudflare's network ranged from about 3:1 to as high as 30:1 in 2025, and DuckDuckGo's stayed below 1:1 for the first three quarters. (Cloudflare (Radar Year in Review 2025), Dec 2025)
  • AI "user action" crawling, where a bot fetches pages in response to a chatbot user's question, grew over 21x from January to early December 2025 on Cloudflare's network. Crawling for model training reached as much as 7-8x search crawling and 32x user action crawling at peak. (Cloudflare (Radar Year in Review 2025), Dec 2025)

Verified Bots is Cloudflare's directory of identified bots, not all bot traffic. The HTML request shares cover requests for HTML content only. Cloudflare calls its crawl-to-refer ratio volatile, and the values here are ranges from its text.

How do websites treat crawlers in robots.txt?

  • 85% of requests for robots.txt files returned a valid 200 status in 2025, against 84% in 2024, and 13% returned a 404, against 14% (HTTP Archive crawl, worldwide). (HTTP Archive (Web Almanac 2025, SEO), Jan 2026)
  • About 94.1% of the roughly 12.9 million sites analysed have a robots.txt file with at least one directive, and the wildcard * is in 97.4% of robots.txt files (2025). (HTTP Archive (Web Almanac 2025, Generative AI), Jan 2026)
  • GPTBot is named in the robots.txt of 4.5% of desktop sites and 4.2% of mobile sites in 2025, up from 2.9% and 2.7% in 2024. ClaudeBot is named on 3.6% and 3.4%, up from 1.9% and 1.6%. (HTTP Archive (Web Almanac 2025, SEO), Jan 2026)
  • Other AI crawlers named in robots.txt in 2025, on desktop and mobile sites: PetalBot 4.0% and 4.4%, CCBot 3.5% and 3.2%, Google-Extended 3.4% and 3.0%, Amazonbot 3.3% and 3.0%, PerplexityBot 2.8% and 2.7%, ChatGPT-User 2.8% and 2.5%. (HTTP Archive (Web Almanac 2025, SEO), Jan 2026)
  • GPTBot is named in the robots.txt of 20.9% of the top 1,000 sites, 12.1% of the top 10,000, 6.1% of the top 100,000, 3.6% of the top 1 million and 4% of the top 10 million (2025). (HTTP Archive (Web Almanac 2025, Generative AI), Jan 2026)
  • 2.13% of desktop sites and 2.10% of mobile sites have a valid llms.txt file, with 324,184 valid files across mobile sites. 39.6% of llms.txt files are related to the All in One SEO plugin and 3.6% to Yoast SEO (2025). (HTTP Archive (Web Almanac 2025, SEO), Jan 2026)
  • Among SEO crawlers named in robots.txt in 2025, AhrefsBot appears on 9.3% of desktop and 9.5% of mobile sites, MJ12bot on 7.3% and 7.3%, AhrefsSiteAudit on 4.6% and 4.3%, and SemrushBot on 3.0% and 3.1%. (HTTP Archive (Web Almanac 2025, SEO), Jan 2026)
  • Googlebot is named in the robots.txt of 6.7% of mobile sites in 2025, against 6.4% in 2024, and Bingbot appears in less than 3% of robots.txt files. (HTTP Archive (Web Almanac 2025, SEO), Jan 2026)

These figures count sites that name a crawler in robots.txt, whether to allow it or to restrict it. Naming a bot is not the same as blocking it. The two robots.txt totals come from different chapters and different queries, so they are not meant to match.

How many websites pass Core Web Vitals and basic SEO checks?

About half pass Core Web Vitals, and desktop does better than mobile. Title tags and HTTPS are on nearly every page; meta descriptions, canonical tags and structured data are not.

  • On desktop, 56% of websites had good Core Web Vitals in 2025, against 55% in 2024 and 41% in 2021. The mobile share was 44% in 2024 and 32% in 2021 (Chrome real-user data, worldwide). (HTTP Archive (Web Almanac 2025, Performance), Jan 2026)
  • 51% of the 1,000 most popular sites have good Core Web Vitals on mobile, against 42% for the next 10,000 and 37% for the next 100,000. Among the top 1,000, 59% pass on desktop (2025). (HTTP Archive (Web Almanac 2025, Performance), Jan 2026)

The Core Web Vitals figures are for sites in the Chrome UX Report, where a site passes when its loading, responsiveness and layout stability measures are all good for most visits. The page-level SEO figures come from the HTTP Archive crawl of those sites.

What do SEO professionals say about their work?

They report growth and worry in the same breath. Most say organic traffic rose, and most fear that AI answers will take clicks away. The survey is self-selected, so it describes its respondents and not the whole trade.

  1. 1 Original content creation 66%
  2. 2 Content updates 42.6%
  3. 3 Technical SEO 42.3%
Tactics with the most positive impact, as named by SEO professionals in Search Engine Journal's survey of 371 respondents in 52 countries. The survey is the publisher's own and self-selected. (Search Engine Journal (State of SEO 2026), Sep 2025)

How much spam has Google removed from search results?

  • Google said its March 2024 core update and spam policy changes cut low-quality, unoriginal content in search results by 45%, against the 40% it had expected. The rollout was completed on 19 April 2024, and the evaluation is Google's own. (Google (March 2024 spam update post), Apr 2024)

Methodology and sources

This page compiles search engine statistics from primary sources only: tracker datasets, company filings and statements, court opinions, regulator decisions, official and academic reports, and vendor studies that publish their method. Each figure is copied as printed and links to the page that carries it, with the date of the data or release. Figures from different producers are never merged or averaged, because they measure different things: StatCounter and Cloudflare count search referrals on their own networks, courts and regulators count queries, and vendor studies use their own panels and keyword sets. Company figures are labelled as the firm's own, court and regulator figures as findings, and forecasts as forecasts with who made them and when. Where a producer has restated a figure, the latest value is used. The page is reviewed monthly, and StatCounter's monthly figures roll forward with each review.
