AI Search Statistics 2027: 60+ Data Points on ChatGPT, AI Overviews and GEO

AI search statistics tell a clear story going into 2027: people still search, but more of them get their answer from ChatGPT, Gemini or a Google AI Overview before they ever reach a website. For businesses in the UK, USA, Canada and Australia, that changes how you get found, how you measure traffic and where your marketing budget should go.

We’ve collected the most important AI search statistics, AI Overviews statistics and generative engine optimization (GEO) statistics, each linked to its original source. Every number is dated, and we update this page every quarter.

AI Search Usage Statistics

AI tools have moved from novelty to everyday habit in just over three years.

• ChatGPT reached 900 million weekly active users in February 2026. (Wikipedia)

• 63% of Gemini users use its voice feature. (TechCrunch)
• ChatGPT held about 79% of global generative AI web traffic in September 2025. (Similarweb)
• Gemini web visits grew 157% between April and September 2025, reaching 1.1 billion monthly visits. (Similarweb)
• Visits to AI platforms in the US grew 28.6% between January 2025 and January 2026. (Similarweb)
• 49% of US adults use AI chatbots, up from 33% in 2024. (Pew Research Center)
• 44% of US adults use ChatGPT, up from 18% in 2023. (Pew Research Center)

• US adults under 50 are about twice as likely to use ChatGPT as those 50 and over (57% vs 28%). (Pew Research Center)

Google AI Overviews and AI Mode Statistics

Google is still the biggest search engine, but more of its results now start with an AI answer.

Reach

• Google AI Overviews reach 2.5 billion monthly users, according to Alphabet CEO Sundar Pichai. (The Motley Fool)
• Google AI Mode has more than 1 billion monthly active users. (TechCrunch)
• AI Mode queries more than double every quarter, but AI Mode still accounts for about 0.34% of all Google searches. (Similarweb)
• About 18% of Google searches by a US panel produced an AI summary in March 2025. (Pew Research Center)
• AI Overviews appeared on 20% or more of searches in 2026. (Similarweb)

Which searches trigger AI Overviews

• 60% of question-format searches produced an AI summary. (Pew Research Center)
• 53% of searches with 10 or more words produced an AI summary. (Pew Research Center)
• 88% of AI summaries cited three or more sources. (Pew Research Center)

Click-through impact

• The #1 organic result gets 34.5% fewer clicks when an AI Overview is present (300,000 keywords, March 2024 vs March 2025). (Ahrefs via Search Engine Land)
• Across 700,000 keywords, CTR fell 15.49% on average when AI Overviews appeared. (Amsive via Search Engine Land)
• Branded keywords gained 18.68% CTR when an AI Overview appeared, while non-branded keywords lost 19.98%. (Amsive via Search Engine Land)
• Organic CTR on AI Overview queries fell from 1.41% to 0.64% year over year. (Seer Interactive via Evergreen Media)
• Paid search CTR on the same queries fell from 21.27% to 9.87%. (Seer Interactive via Evergreen Media)

Our takeaway: branded searches hold up, generic ones lose clicks. Building a brand people search for by name is now an SEO strategy.

Zero-Click Search Statistics

A “zero-click” search ends without the user visiting any website. AI answers are speeding up a trend that started years ago.

• 68.01% of Google searches ended without a click in 2026. (Similarweb)
• The zero-click rate was about 45% in 2016 and about 65% in 2020, a rise of 23 percentage points in a decade. (Similarweb)
• Google users clicked a traditional result on 8% of visits when an AI summary appeared, compared with 15% when it didn’t. (Pew Research Center)
• Users clicked a link inside the AI summary on just 1% of visits. (Pew Research Center)
• Users ended their browsing session on 26% of pages with an AI summary, versus 16% without one. (Pew Research Center)
• Google AI Mode sends a referral on only 1.6–2.5% of queries, compared with about 17–19% for traditional search. (Similarweb)
• Pew’s study covered 68,879 Google searches by 900 US adults. (Pew Research Center)

Our takeaway: traffic is no longer the only measure of search success. Track brand mentions in AI answers, branded search volume and enquiries, not just sessions.

AI Referral Traffic Statistics

AI tools send fewer visitors than Google, but the visitors they do send often behave better.

Growth

• AI traffic to US retail sites rose 393% year over year in Q1 2026. (TechCrunch, Adobe data)
• AI traffic to US retailers jumped 693% during the 2025 holiday season. (TechCrunch, Adobe data)
• Adobe’s analysis covered more than 1 trillion visits to US retail sites. (TechCrunch)
• Across the US, AI referral traffic stayed flat between January 2025 and January 2026, even as visits to AI platforms grew 28.6%. (Similarweb)

Quality

• AI traffic to US retailers converted 42% better than other traffic in March 2026. A year earlier it converted 38% worse. (TechCrunch, Adobe data)
• Revenue per visit from AI traffic was 37% higher than from non-AI sources in March 2026. (TechCrunch, Adobe data)
• AI visitors spent 48% longer on retail sites and viewed 13% more pages. (TechCrunch, Adobe data)
• ChatGPT referrals converted at 7% on transactional sites, compared with 5% from Google. (Similarweb)
• Visitors from ChatGPT spent about 15 minutes on site versus 8 minutes from Google, and viewed 12 pages versus 9. (Similarweb)

Shopping behaviour

• 39% of US consumers surveyed by Adobe used AI for online shopping, and 85% of them said it improved their experience. (TechCrunch, Adobe data)
• 35% of US consumers use AI at the product discovery stage, compared with 13.6% who use search. (Similarweb)

Our takeaway: don’t judge AI search by visit counts alone. Set up a separate AI referral channel in GA4 and compare its conversion rate with Google organic.

AI Citation and GEO Statistics

Generative engine optimization (GEO) is about getting your brand mentioned and cited inside AI answers. These numbers show what AI tools actually reward.

What predicts AI visibility

Source: Ahrefs, study of 75,000 brands, May 2025.

• Branded web mentions correlate three times more strongly with AI visibility than backlinks. (Ahrefs)
• Brands in the top 25% for web mentions averaged169 AI Overview mentions, about 10 times more than brands in the 50–75% band (14 mentions). (Ahrefs)
• About 26% of brands studied had zero AI Overview mentions. (Ahrefs)

Where citations come from

• Only 38% of pages cited in Google AI Overviews rank in the organic top 10, down from 76% in Ahrefs’ July 2025 study. Ahrefs notes better citation detection explains part of the change. (DesignRush, Ahrefs data)
• About 31% of AI Overview citations come from pages ranking beyond the top 100. (DesignRush, Ahrefs data)
• YouTube makes up nearly 6% of all AI Overview citations, and its share grew 34% in six months. (DesignRush, Ahrefs data)
• Wikipedia, YouTube and Reddit together made up 15% of sources cited in Google AI summaries. (Pew Research Center)

Our own data: AI citations differ hugely by platform

We checked our own website, ingeniousnetsoft.com, in Semrush’s AI Search report on 30 September 2026. Of 52 pages cited across AI platforms:

The same website was cited more than seven times as often in Google AI Mode as in ChatGPT. One site is a small sample, but it shows why you should track each AI platform separately rather than treating “AI search” as one channel.

Consumer Trust and Behaviour Statistics

People use AI answers more every year, but they don’t fully trust them. That gap is an opportunity for brands that show real proof.

• 56% of UK adults say they would trust an AI-written news story less than one written by a person. (Ofcom via Broadband TV News)
• 63% of US adults believe AI is advancing too quickly. (Pew Research Center)
• 71% of US adults think AI will make personal information less secure. (Pew Research Center)
• 67% of US adults lack confidence in government regulation of AI. (Pew Research Center)
• 35% of US consumers use AI to discover products, and 32.9% use it to evaluate them, compared with 15% who use search at the evaluation stage. (Similarweb)

Our takeaway: AI often creates the shortlist, but people still check before they buy. Real reviews, case studies with numbers, and named experts are what close the deal.

B2B Buyer AI Statistics

Business buyers lean on AI for research, then turn to people to confirm what it told them.

• 45% of B2B buyers used AI during their most recent purchase. (Gartner)
• 67% of B2B buyers prefer a rep-free buying experience. (Gartner)
• 69% of B2B buyers turn to a sales rep specifically to validate insights generated by AI. (Gartner)
• 35.9% of Canadian workers used generative AI tools in their main job in the past 12 months, rising to 75.1% of managers. (Statistics Canada via Global News)

Our takeaway: for B2B, make sure AI tools describe your services, pricing model and proof accurately, because that description shapes the shortlist before a buyer ever contacts you.

AI Search Advertising Statistics

Ads are moving inside AI answers too, and the rules for paid search are changing with them.

• Ads in AI Overviews were live in 12 markets by December 2025, including the US, Canada and Australia. (PPC News Feed)
• Eligible formats are text and Shopping ads from existing Search, Shopping and Performance Max campaigns. (PPC News Feed)
• Ads inside Google AI Mode are served through AI Max and Performance Max campaigns, and were announced at Google Marketing Live 2026 as a test in the US. (DGTalents)
• Google says AI Max for Search can bring up to 14% more conversions at a similar CPA, and up to 27% for campaigns built mainly on exact and phrase match. (Search Engine Land)
• An independent review of 250+ AI Max campaigns found a 13% median revenue lift but a 16% median CPA increase. (PPC Live)
• CMOs allocate 15.3% of marketing budgets to AI, but only 30% say they’re ready to scale it. (Gartner)

Our takeaway: if you run Google Ads, AI Max and PMax are now the doorway to AI placements. Test them with clear guardrails rather than switching them on blindly. For a real example, see how we took an online motorcycle parts store to 18.9x ROAS with Google Ads, or learn more about our PPC management services.

Marketer Adoption and GEO Budget Statistics

Most marketers now spend on AI visibility. Far fewer can prove it’s working.

Budgets

• Marketers put about 24% of search and content budgets into AI visibility. (Fractl via Relevant Audience)
• 82% of marketers allocate at least some budget to AI visibility, and 43% spend more than 20% of their search and content budget on it. (Fractl via Relevant Audience)
• 69% of search professionals have a budget for AI search optimization, up from 38% in 2025. (SEOFOMO)
• 75% have a dedicated AI search strategy, up from 51%. (SEOFOMO)
• 98% of search professionals have been asked about AI search visibility by clients or bosses. (SEOFOMO)

Measurement and results

• 92% of search professionals track AI visibility and citations, up from 78%. (SEOFOMO)
• Yet 71% of marketers don’t track competitive share of voice in AI answers. (Scribewise via Relevant Audience)
• 56% report at least some positive business impact from AI search optimization, but only 5% call it significant. (SEOFOMO)
• 19% attribute more than 5% of site revenue to AI search, double the 8% in 2025. (SEOFOMO)
• The top challenge is reliably measuring AI search visibility (19%), followed by understanding what drives it (14%). (SEOFOMO)
• The most impactful tactics reported: expanding content coverage (18%), improving technical crawlability (17%) and restructuring content for easier extraction(16%). (SEOFOMO)

Note: the SEOFOMO survey covers 171 search professionals across 36 countries (August 2026), so treat it as a directional signal.

AI Search Statistics by Country: UK, US, Canada, Australia

Most AI search statistics are US-only. Here’s what we could verify for each of our four core markets. Each survey measures something slightly different, so compare with care.

Australia, by tool

(Roy Morgan):

• ChatGPT: 10.5 million users (45%)
• Google Gemini: 5 million (21%)
• Microsoft Copilot: 4 million (17%)
• Claude: 777,000 (3%)
• Usage peaks at 74% among 25–34-year-olds and drops to 31% among those 65+.

AI search ads by country: ads in Google AI Overviews were available in the US, Canada and Australia by December 2025. The UK was not on that list, so UK advertisers should check availability in their own account. (PPC News Feed)

What These Statistics Mean for Your Business

Six practical moves, each backed by the numbers above:

1. Get talked about, not just linked to. Branded web mentions predict AI visibility three times better than backlinks. Earn mentions through PR, podcasts, reviews, industry lists and original data like this page.
2. Build a brand people search for by name. Branded keywords gained CTR when AI Overviews appeared, while generic ones lost it. Brand demand is now SEO protection.
3. Write for questions. 60% of question-style searches trigger an AI summary. Add clear, direct answers to the questions your buyers ask, in FAQs and service pages.
4. Track each AI platform separately. Our own site was cited 45 times in AI Mode but only 6 times in ChatGPT. One “AI” number hides the real picture.
5. Measure quality, not just visits. AI visitors convert well in several studies. Create an AI referral channel in GA4 and compare it with Google organic.
6. Show proof. People use AI to shortlist but still verify. Case studies with real numbers, named experts and genuine reviews win the final decision.
