85+ SEO Statistics for 2026: Every Source Checked

Search got bigger. Clicks got scarcer. Every Google SEO statistic below is a footnote to that trade.

Key Takeaways

• AI Overviews cut clicks roughly in half where they appear. Pew measured an 8% click rate on traditional results with an AI Overview present, against 15% without. Ahrefs puts the CTR damage to the top-ranking page at 58%.
• Google is not dying. Its worldwide search share dipped below 90% in late 2024, then recovered to 91.34% by August 2026. ChatGPT’s traffic runs at roughly one-fourteenth of Google’s.
• Nobody agrees how often AI Overviews appear, and that’s a methodology story. Pew saw them on 18% of real users’ searches, Semrush measures 15.69% of its keyword panel, BrightEdge reported over 11% of tracked queries. Pick the panel closest to your own query mix.
• Most content still earns nothing. 96.55% of pages get zero organic traffic from Google, and 94% of online content has zero external links.
• Local search moved fastest. US consumers using ChatGPT or other generative AI for local business recommendations jumped from 6% to 45% in a single year, per BrightLocal.
• Click data is a confirmed ranking input. Google’s NavBoost, described under oath in the US v. Google trial, re-ranks results using a rolling 13 months of click behavior.

Top SEO Statistics for 2026

If you only take four SEO stats into your next planning meeting, take these four numbers.

The Four Numbers That Define Search in 2026

1. Users who see an AI Overview click a traditional search result in 8% of visits, versus 15% when no AI Overview appears (Pew Research Center, July 2025; 900 US adults, 68,879 real searches, 12,593 of them AIO-triggered).

2. Total search impressions grew more than 49% in the year following the AI Overviews launch, while click-throughs declined nearly 30% over the same window (BrightEdge, May 2025, enterprise keyword panel; vendor-published).

3. Google’s worldwide all-devices search share stood at 91.34% in August 2026, fully recovered from its sub-90% dip in late 2024 and early 2025 (StatCounter Global Stats, pulled August 2026).

4. Use of ChatGPT and other generative AI tools for local business recommendations grew from 6% of US consumers in 2025 to 45% in 2026, making AI the third most popular source of business recommendations (BrightLocal Local Consumer Review Survey 2026, February 2026, n=1,002 US adults).

Why These Four SEO Stats Matter Most

Each one is a live measurement, not a projection, and each comes from a different kind of panel: a behavioural study of real users, an enterprise keyword tracker, a referral-based market share series, and a consumer survey. Agreement across four unrelated methods is the strongest signal in this whole page.

“Users who encountered an AI Overview clicked a traditional search result in just 8% of visits, vs 15% when no AIO appeared.” (Pew Research Center, July 2025.)

Search Engine Market Share Statistics

Google still dominates, but the 2024-2026 trend line has a shape most roundups miss: a dip, then a recovery.

Google’s Dip and Recovery

5. Google’s worldwide all-devices search share bottomed at 89.34% in October 2024, its weakest reading in the recent StatCounter series (StatCounter, monthly data).

6. In March 2025, the month most 2025 roundups cite, Google held 89.71% worldwide, with Bing at 4.01% and Yandex at 2.51% (StatCounter).

7. By August 2026 Google was back to 91.34% worldwide, with Bing at 4.31% and Yandex at 1.05% (StatCounter, pulled August 2026). The “Google is collapsing” narrative of early 2025 did not survive contact with the next 17 months of data.

8. Desktop is where Bing actually competes: in March 2025, Google’s desktop-only share fell to 79.1% while Bing climbed to 12.21% (StatCounter desktop view).

9. On mobile, Google never blinked. Its worldwide mobile share stayed between 93.74% and 95.11% through every month of 2025 and reached 96.04% by mid-2026 (StatCounter mobile view).

10. For reference against older roundups: Google’s worldwide share was 91.38% in December 2020 (StatCounter), a figure this page has carried since 2021. Five and a half years later the number is nearly identical, with a dip and recovery in between.

A caveat that applies to every number in this section: StatCounter measures search referrals to sites running its tracking code, not queries. If Google answers more questions inside the SERP, its measured share can fall even when query share is unchanged.

How Big Search Still Is

11. Total Google search volume grew about 21.6% from 2023 to 2024, per clickstream analysis in the Datos State of Search Q1 2025 report (Datos, a Semrush company, May 2025; the full report sits behind an email gate). Search demand is growing, not shrinking.

12. Google processes over 3.5 billion searches a day, roughly 40,000 every second, per Internet Live Stats, an estimate this page has cited since 2021.

13. The web underneath keeps growing too: Q2 2026 closed with 401.6 million registered domains across all top-level domains, up 8.1% year over year (Verisign Domain Name Industry Brief, July 2026).

14. .com and .net together account for 179.1 million of those registrations (Verisign DNIB, Q2 2026).

AI Overviews and Zero-Click Statistics

This is where SEO actually changed between 2024 and 2026. Different measurement firms publish different numbers, so I cite the panels and explain the spread instead of pretending one true number exists.

Zero-Click Search Rates

15. 58.5% of US Google searches and 59.7% of EU Google searches ended in zero clicks in 2024 (SparkToro / Datos Zero-Click Study, July 2024, tens of millions of clickstream panelists).

16. For every 1,000 US Google searches, only 360 clicks reached the open web. In the EU it was 374 (SparkToro / Datos, July 2024).

17. Almost 30% of US clicks went to Google-owned properties like YouTube and Maps (SparkToro / Datos, July 2024).

18. Datos’s narrower follow-up measurement found 27.2% of US Google searches in March 2025 ended without any click at all, up from 24.4% a year earlier (Datos State of Search Q1 2025, email-gated report; Datos is Semrush-owned, so flag accordingly).

19. In the same gated report, organic clicks fell to 40.3% of US Google sessions in March 2025, down from 44.2% the year prior.

The 58.5% and 27.2% figures are both real. They answer different questions: the first counts query refinements and abandoned sessions as zero-click, the second only counts sessions that end with no click anywhere.

What AI Overviews Do to Clicks

20. Only 1% of users clicked a citation link inside an AI Overview itself (Pew Research Center, July 2025). Being cited in an AIO is visibility, not traffic, which is why it is worth checking whether your own pages appear in AI Overviews before you model the traffic impact.

21. 26% of sessions with an AI Overview ended with the user leaving Google entirely, versus 16% of sessions without one (Pew, July 2025).

22. As of December 2025 data, the presence of an AI Overview correlates with a 58% lower click-through rate for the top-ranking page, up from the 34.5% drop in the original 2024 study (Ahrefs, study updated February 2026, 300,000 keywords; vendor-published).

23. Semrush’s counterweight: tracking the same keywords before and after an AI Overview appeared, the zero-click rate actually decreased slightly, from 33.75% to 31.53% (Semrush, December 2025, 200,000+ keyword panel). Correlation studies and same-keyword studies disagree, which tells you the honest answer is “it depends on the query.”

24. 53% of Americans say they have at least some trust in the information AI summaries show, while 28% find them not too useful or not useful at all (Pew Research Center, October 2025 survey of 5,153 US adults).

How Often AI Overviews Actually Appear

Trigger rates depend entirely on whose keyword universe you ask. The spread is the story. Several of the numbers below come out of Semrush‘s keyword panel, so read them as one vendor’s slice of search rather than the whole of it.

25. In Pew’s panel of real user behavior, 18% of all March 2025 searches triggered an AI Overview, and 60% of question-style searches did (Pew, July 2025).

26. Semrush measured AI Overview presence at 6.49% of queries in January 2025, peaking around 24.61% in July 2025, then pulling back to 15.69% by November 2025 (Semrush, December 2025, 10M+ keyword panel). Google tested aggressively, then throttled.

27. BrightEdge’s one-year review reported AI Overviews appearing on over 11% of tracked Google queries, a 22% increase since their debut, with the strongest presence in healthcare, education, B2B tech, and insurance (BrightEdge, May 2025).

28. Google is monetizing AIO SERPs: ads at the bottom of an AI Overview SERP appeared on under 1% of them in March 2025 and 25% by late 2025 (Semrush, December 2025).

29. Navigational queries triggering an AI Overview grew from 0.84% in October 2024 to 10.33% by October 2025 (Semrush, December 2025). Even branded searches now intersect with AI summaries.

AI Platforms vs Google Traffic

30. AI platforms generated more than 1.1 billion referral visits in June 2025, up 357% year over year (Similarweb 2025 Generative AI Landscape, December 2025; panel-modeled, treat as directional).

31. ChatGPT’s share of worldwide generative AI web traffic slid from roughly 76% to around 53% between June 2025 and May 2026, while Google Gemini climbed from under 9% to roughly 27% (Similarweb, updated July 2026). The share is moving, but it is moving between AI tools, not away from search.

32. ChatGPT.com received about 5.8 billion visits in August 2025. Google received roughly 83.8 billion the same month, about 14 times more (Similarweb data reported September 2025).

33. 95.3% of ChatGPT visitors also visited Google in August 2025, while only 14.3% of Google visitors visited ChatGPT (Similarweb, September 2025). ChatGPT is supplementary, not substitutive.

34. US users spent 10.55% of their online time on traditional search engines versus 0.55% on AI tools (Datos State of Search Q1 2025, email-gated report).

Click-Through Rate and Ranking Statistics

Two CTR datasets with different methodologies, plus what the antitrust trial finally put on the record.

CTR by Position

35. On a clean Google SERP with no AI Overview, map pack, or rich features, position 1 captures roughly 39.8% CTR, position 2 gets 18.7%, and position 3 gets 10.2%. The top three positions take 68.7% of clicks combined (First Page Sage, 2026 report, updated May 2025; meta-analysis, sample not fully disclosed).

36. Featured snippets pull a 42.9% CTR, the highest of any single SERP element (First Page Sage, 2026 report).

37. Position 1 organic gets roughly 19x more clicks than the top paid result (First Page Sage, 2026 report).

38. The second page of Google remains where clicks go to die. Backlinko’s 2019 study of 5 million search results found 0.78% of searchers clicked a second-page result. The current version of the study puts it at 0.63%.

39. For readers comparing against older data: Advanced Web Ranking’s 2020 dataset put the first mobile organic result at a 26.9% average CTR, a figure the earlier version of this page cited. AWR’s 2025 quarterly reports show every top position bleeding CTR since (see below).

How CTR Is Shifting

40. Year over year, 2025 versus 2024, position 2 lost 1.16 CTR percentage points on mobile and 1.27 points on desktop (Advanced Web Ranking Q4 2025 CTR report; vendor GSC aggregation across millions of keywords).

41. In Q3 2025, queries of 4+ words were the only group holding steady CTR, and on branded SERPs position 1 desktop lost 1.52 points while positions 2 through 6 gained a combined 8.71 points (AWR Q3 2025 report). Clicks are spreading downward even on branded searches.

What the Antitrust Trial Put on the Record

The 2023 US v. Google trial disclosed more ranking-system specifics than a decade of Google blog posts. The figures below come from the trial exhibits and sworn testimony.

42. NavBoost, one of Google’s strongest ranking signals, re-ranks results using click data from a rolling 13-month window. Confirmed under oath by Google’s Pandu Nayak in October 2023.

43. Glue is NavBoost’s counterpart for SERP features, aggregating “clicks, hovers, scrolls, and swipes” into a common metric (Oard exhibit, November 15, 2023).

44. Google’s index contained roughly 400 billion documents as of 2020 (Nayak testimony).

45. Google uses “maybe over a hundred” ranking signals, per Nayak, well below the “200+ signals” line the industry repeated for years.

46. The 2025 remedies opinion later described two top-level ranking signals, Quality (Q*) and Popularity (P*), fed by Topicality (T*), NavBoost, and RankBrain.

The practical implication: what users do after the click is a real ranking input. Titles that earn the click and pages that keep people off the back button matter more than they did when Google publicly denied click-based ranking.

Content, Keyword, and Link Statistics

The most repeated SEO statistic of the last decade still holds. It just got worse.

Who Actually Gets Organic Traffic

47. 96.55% of all studied pages get zero organic traffic from Google, and just 1.94% get between 1 and 10 monthly visits (Ahrefs, September 2023, roughly 14 billion pages; predates AI Overviews, so treat as a floor).

48. When this page first cited that study in 2021, the figure was 90.63%, from Ahrefs’ 2020 update (the 2018 original reported 90.88%). Three editions, one direction: the zero-traffic share keeps climbing.

Link Statistics

49. 94% of online content gets zero external links, and only 2.2% earns links from multiple websites (Backlinko / BuzzSumo, February 2019, 912 million blog posts; seven years old, no published refresh, but no large-scale crawl since has contradicted the shape).

50. 1.3% of articles generate 75% of all social shares (Backlinko / BuzzSumo, February 2019).

51. Ahrefs’ 2020 analysis found 66.31% of pages had not a single backlink, a figure this page has carried since 2021.

52. 73.6% of domains with at least 10,000 monthly organic visits have reciprocal links with other sites (Ahrefs, study of 140,592 domains).

Keyword and Query Statistics

53. 0.16% of the most popular keywords drive 60.67% of all searches, an Ahrefs-era figure this page has cited since 2021. Its original study page is no longer traceable, so treat it as directional: a tiny head of queries carries most volume, and the long tail is where the entry points are.

54. About 8% of search queries are phrased as questions (Moz / Jumpshot clickstream analysis, 2017).

55. In the same 2017 Moz analysis, Google-owned properties earned 11.8% of clicks from distinct searches, with YouTube alone drawing 1.8% of all search clicks. The earlier version of this page attributed the 1.8% to all Google properties; the corrected split is worth having.

56. Organic search offered roughly 20x more traffic opportunity than PPC across mobile and desktop (Moz / Jumpshot, 2017). An eight-year-old ratio, but the 2026 First Page Sage 19x figure above says it barely moved.

Technical SEO Statistics

The HTTP Archive Web Almanac is the strongest primary source for what the web actually ships: a 2024 crawl of 16.9 million websites.

What the Web Actually Ships

57. 89% of desktop pages and 88.9% of mobile pages used HTTPS in 2024 (HTTP Archive 2024 Web Almanac).

58. 70% of desktop pages have a non-empty H1, 71% have an H2, and 59% have an H3 (HTTP Archive 2024).

59. 29% of desktop and 22% of mobile pages had misapplied image tags that broke the document head, and div-in-head errors jumped from 4% in 2022 to roughly 11% in 2024 (HTTP Archive 2024).

60. The two most-used meta robots “rules” in 2024 were “follow” and “index”, neither of which is a valid directive Googlebot acts on (HTTP Archive 2024). Real technical SEO mistakes still ship at scale.

61. The median page carries 14.5 images; home pages average 18.5 and inner pages 10.5 (HTTP Archive 2024).

Core Web Vitals and Algorithm Updates

62. Interaction to Next Paint replaced First Input Delay as a Core Web Vital on March 12, 2024. At or below 200ms counts as “Good”; above 500ms is “Poor” (web.dev).

63. The March 2024 core update merged the Helpful Content System into Google’s core ranking systems, targeting a 40% reduction in low-quality results, which Google later revised to 45% (Google Search Central blog, March 2024; self-reported, no published methodology).

Local, Mobile, and Voice Search Statistics

Local search behavior shifted faster than almost anything else in 2025-2026, and voice search is where this page holds numbers the industry still quotes.

Local SEO Statistics

64. 97% of consumers read reviews online when browsing for businesses in 2026, and 41% say they “always” read reviews, up from 29% in 2025 (BrightLocal Local Consumer Review Survey 2026, February 2026, n=1,002 US adults).

65. Google’s share as a review source dropped from 83% in 2025 to 71% in 2026, while Apple Maps use for reading reviews nearly doubled, from 14% to 27% (BrightLocal, February 2026).

66. Only 35% of small and medium businesses have a Google Business Profile, meaning 65% still lack one (BrightLocal SMB research, cited in the 2026 Local Consumer Review Survey).

67. Whether a business is open at the time of search ranks as the 5th most influential local pack signal, per the expert panel in the Whitespark Local Search Ranking Factors 2026 (November 2025, 47 local SEO experts; qualitative consensus, not correlation data, and the full rankings are gated).

68. For the year-over-year contrast: BrightLocal’s 2020 edition found 93% of consumers used the internet to find a local business, 87% read reviews, and 94% said positive reviews made them more likely to use a business (BrightLocal 2020, n=1,013). Review reading went from common to near-universal in six years.

Mobile Search Statistics

The mobile numbers below are the ones this page has carried since 2021. They’re old, they’re still quoted everywhere, and I date them so you can decide what they’re worth.

69. Mobile accounted for about 58% of all Google searches, per Hitwise’s 2016 US mobile search report. Hitwise’s public report line has since been discontinued; no comparable current figure exists from the same source.

70. Google showed an average of just 8.5 organic results on page 1 of mobile SERPs, per Searchmetrics’ 2018 Universal Search study. With AI Overviews averaging well over half the viewport, effective organic real estate has only shrunk since.

71. Jumpshot’s 2017 clickstream data split Google mobile searches three ways: 40.9% ended in an organic click, 2% in a paid click, and 57.1% in no click at all (Moz / Jumpshot, 2017). This page has carried that split since 2021, and the SparkToro and Datos numbers above are its 2024 successor.

72. Roughly 30% of all mobile searches were location-related, and 28% of searches for something nearby resulted in a purchase (Google / Think with Google, circa 2016).

73. 51% of smartphone users discovered a new company or product while searching on their phone (Google / Think with Google, circa 2016).

74. People using Google for local searches visited 1.5 billion locations every month as a result, which the same research framed as 32.8% of all internet users visiting a local business (Google / Think with Google, circa 2016).

Voice Search Statistics

75. The mean Ahrefs Domain Rating of a Google Home result is 76.8, per Backlinko’s study of 10,000 Google Home results (2018). Link authority strongly predicted voice answers, and this remains the most-cited voice SEO figure on the web.

76. The typical voice search answer is only 29 words long, written at a ninth-grade reading level (Backlinko, 2018).

77. The page a voice answer is pulled from averages 2,312 words (Backlinko, 2018).

78. About 75% of voice search results come from a page ranking in the desktop top 3 for that query (Backlinko, 2018). Voice SEO was never a separate discipline; it’s regular SEO with a snippet-shaped answer.

79. 48% of consumers reported using voice assistants for general web search in a 2019 Adobe survey of roughly 1,000 US adults.

80. 27% of the global online population was using voice search on mobile, per Global Web Index data (n=400,000) that Google’s Think with Google published in 2018. Neither has refreshed it, so treat it as vintage.

81. The famous “20% of mobile queries are voice searches” line traces to a May 2016 Sundar Pichai statement at Google I/O that Google has never updated. It still gets requoted as a current statistic on dozens of lists. It isn’t one.

YouTube and Video SEO Statistics

82. YouTube was the number one video channel, used by 55% of marketers, in Social Media Examiner’s 2020 industry report.

83. Comment count, view count, shares, and likes all correlated strongly with higher YouTube rankings in Backlinko’s analysis of 1.3 million YouTube videos (2017).

84. YouTube’s recommendation algorithm tends to point users toward progressively longer videos (Pew Research Center, November 2018).

85. Blog posts containing video attracted almost triple the linking domains of plain-text posts in Moz’s early research. The study is over a decade old; I keep it because the earlier version of this page cited it, and because nothing since suggests video hurts linkability.

SEO Industry and ROI Statistics

What SEOs Say the Channel Delivers

86. 91% of respondents in Conductor’s State of Organic Marketing research said SEO positively impacted website performance and overall marketing goals (2025 edition, 350+ digital marketing, SEO and content marketing professionals; vendor-published).

Link Building Statistics

87. 94% of SEO professionals believed links will still be a Google ranking factor in five years, and 73% believed so for ten years out (Aira State of Link Building, 2022, 270 SEOs; Aira has not published a newer link building edition, so this is the most recent industry read).

88. 32% of SEOs said building a single link takes 1 to 2 hours (Aira, 2022).

SEO Statistics FAQ

Are SEO statistics for 2026 actually different from 2025?

In two specific ways. AI Overview prevalence more than doubled across 2025 in Semrush’s panel, from 6.49% in January to 15.69% by November after a mid-year peak near 25%. And generative AI as a local recommendation source jumped from 6% to 45% of US consumers in BrightLocal’s survey. CTR by position, technical adoption, and link distribution drift slowly. If a statistic is described as 2026 but the underlying study is from 2020, treat it as a 2020 number.

Why do AI Overview statistics vary so much across sources?

Because every source measures a different universe. Pew watched 900 real users and saw AI Overviews on 18% of searches. Semrush samples a 10M+ keyword panel and gets 15.69%. BrightEdge tracks enterprise commercial keywords and reported over 11%. All are real measurements of different slices of search. Pick the panel closest to your own query mix; a single true number does not exist.

Is SEO still worth investing in given AI Overviews?

BrightEdge found total search impressions grew over 49% in the year after the AI Overviews launch while click-throughs declined about 30%. Search is expanding faster than clicks are shrinking, but impression-to-click conversion is harder. The work has shifted from “rank top three” to “be the source the AI Overview cites and still earn the click that does come.” 91% of SEO pros in Conductor’s research say the channel still positively impacts marketing goals.

What percentage of searches result in zero clicks?

Two reliable answers, depending on definition. SparkToro and Datos found 58.5% of US Google searches in 2024 ended without a click to the open web, a broad definition that includes abandoned and refined searches. Datos’s narrower March 2025 measurement, counting only sessions that ended with no click anywhere, was 27.2%. Both are correct; they answer slightly different questions.

Does Google really use click data to rank pages?

Yes, and it’s no longer speculation. Pandu Nayak confirmed under oath in the 2023 US v. Google trial that NavBoost, which uses a rolling 13-month window of click data, is one of Google’s strongest ranking signals. The Glue system does the same for SERP features using clicks, hovers, scrolls, and swipes.

Which SEO statistic is most cited but least trustworthy?

The “20% of mobile queries are voice searches” figure, from a May 2016 Sundar Pichai statement Google never updated. Same for “78% of local mobile searches result in an offline purchase,” which traces to a 2014 Google/Nielsen study no longer hosted by Google. Both still circulate on 2026 lists. Neither is verifiable to a current primary source.

Where can I find raw SEO data myself?

Five sources this page leans on most: StatCounter Global Stats for live market share, the HTTP Archive Web Almanac for technical adoption, Pew Research Center for AI Overview behavioral data, SparkToro and Datos for clickstream trends, and Verisign’s quarterly Domain Name Industry Brief for domain growth. All have free public versions. For tracking whether your own pages appear in AI Overviews, I built a free AI Overview checker.

Sources and Methodology

Most SEO statistics roundups recycle numbers from 2019 and relabel them with the current year. Every figure on this page is dated, sampled, and traced to a primary source, with vendor-funded research flagged in line. Where a source publishes behind an email gate, that is stated. And because plenty of sites still reference the older statistics this page has carried since 2021, those stay here too, clearly dated, with the current number beside them.

Every statistic above cites the primary study, with the publication date stated in line. Where the publisher has a commercial stake in the conclusion (Ahrefs, Semrush, BrightEdge, BrightLocal, First Page Sage, Advanced Web Ranking), that is flagged where the number appears. Figures older than 2024 are date-stamped so readers can weigh them. Statistics the earlier version of this page cited are retained with their original figures and sources, updated alongside newer editions where those exist.

Two Search Engine Journal State of SEO survey figures carried by an earlier version of this page were dropped in the August 2026 pass: the cited report is email-gated, the URL now serves a later edition, and neither figure could be confirmed at any live source. Three further categories were excluded rather than repeated: modern voice search percentages with no primary source behind them, the 2014 Google/Nielsen offline-purchase figure, and AI Overview prevalence claims that could not be confirmed at their stated source. Four statistics from the Datos State of Search Q1 2025 report (numbers 11, 18, 19, and 34) come from a report that is free but email-gated; they are quoted as documented in the April 2026 source audit for this page, with the gate disclosed where each appears.
