15 Google Search Statistics for 2026: Market Share, AI & Clicks

Google handled 89.94% of worldwide search engine traffic in September 2026, according to StatCounter, but searching on Google now sends far fewer clicks to websites. SparkToro’s 2026 clickstream study found 68.01% of US Google searches ended without a click, and Ahrefs found that an AI Overview correlates with a 58% lower click-through rate for the top-ranking page.

The 15 Google search statistics below cover market share, zero-click searches, AI Overviews and AI Mode, and search advertising. Each statistic is attributed to its original source, including Google’s own earnings remarks, Pew Research Center, Ahrefs, SparkToro and the IAB, with links in the Sources section.

What is Google’s search market share in 2026?

1. Google has 89.94% of the worldwide search engine market

StatCounter Global Stats data for September 2026 puts Google’s worldwide search engine market share at 89.94% across all devices. Bing is a distant second at 5.29%, followed by Yahoo (1.36%), Yandex (1.3%), DuckDuckGo (0.74%) and Baidu (0.44%).

2. Google handles 95.68% of mobile searches

On mobile devices Google’s lead is even larger. StatCounter’s mobile search data shows Google at 95.68% of worldwide mobile search in September 2026, with Yandex at 1.21% and Bing at just 0.69%. Google’s position as the default search engine on Android phones and in Apple’s Safari browser helps explain the gap.

3. Google’s Search and other revenue grew 17% in Q2 2026

In Alphabet’s Q2 2026 earnings remarks (July 22, 2026), CEO Sundar Pichai reported 17% revenue growth in Search and other, after 19% growth in Q1 2026. Despite competition from AI chatbots, Google says search usage reached an all-time high during the 2026 World Cup.

How many Google searches end without a click?

4. 68.01% of US Google searches end without a click

SparkToro’s 2026 zero-click study (June 9, 2026), based on Similarweb’s US desktop and mobile panel for January to April 2026, found that 68.01% of Google searches ended without a click on any result. That is up from 60.45% in 2024 and 49% in 2019. SparkToro notes the true rate is likely higher because the panel excludes searches in the Google app.

5. Users click a result on 8% of visits when an AI summary appears, versus 15% without

Pew Research Center’s 2025 study tracked the browsing of 900 US adults in March 2025. When a Google search showed an AI summary, users clicked a traditional search result on 8% of visits, compared with 15% when no summary appeared. They clicked a link inside the AI summary on just 1% of visits.

6. Users ended their browsing session on 26% of searches with an AI summary

The same Pew Research Center study found that users ended their browsing session entirely on 26% of Google results pages with an AI summary, compared with 16% of pages with only traditional results. In other words, many people treat the AI answer as the end of the search.

7. AI Overviews correlate with a 58% lower click-through rate for the #1 result

Ahrefs’ February 2026 study of 300,000 keywords found that when an AI Overview appears, the top-ranking page’s average click-through rate is 58% lower than expected, up from a 34.5% reduction in Ahrefs’ April 2025 study. For AI Overview keywords, position-one CTR fell from 7.3% in December 2023 to 1.6% in December 2025. The effect shrinks lower down the page, from a 50.8% reduction at position 2 to 19.4% at position 10.

8. 99.2% of keywords that trigger AI Overviews are informational

According to Ahrefs’ 2025 AI Overviews research, 99.2% of keywords that trigger AI Overviews have informational intent. Commercial and transactional searches (“buy”, “pricing”, brand names) are much less likely to show an AI Overview, so they still send relatively more clicks.

Google AI Overviews and AI Mode statistics

9. 18% of Google searches produced an AI summary in March 2025

In Pew Research Center’s browsing data, 18% of all Google searches (12,593 of 68,879 unique searches) produced an AI summary in March 2025. SparkToro’s 2026 study estimates AI Overviews now appear on more than 20% of searches.

10. AI Overviews have more than 2 billion monthly users

Google said in its Q2 2025 earnings remarks that AI Overviews had over 2 billion monthly users across more than 200 countries and territories and 40 languages. Google also said AI Overviews drive over 10% more queries globally for the types of queries that show them.

11. Google’s AI Mode passed 1 billion monthly active users

In Alphabet’s Q2 2026 earnings remarks, Sundar Pichai said AI Mode, Google’s chatbot-style search experience, had surpassed 1 billion monthly active users, up from more than 100 million in the US and India a year earlier.

12. Only 0.34% of Google searches reached AI Mode in early 2026

Despite AI Mode’s large user count, SparkToro’s clickstream data shows that only 0.34% of US Google searches reached AI Mode from January to April 2026. Most people still use the classic results page, where AI Overviews, not AI Mode, are the main AI feature.

13. AI Mode queries are three times longer than traditional searches

According to Alphabet’s Q4 2025 earnings remarks (February 4, 2026), queries in AI Mode are three times longer than traditional searches, and daily AI Mode queries per user in the US doubled after launch. People ask AI Mode full questions rather than typing two or three keywords.

14. Nearly one in six AI Mode queries uses voice or images

In the same Q4 2025 remarks, Google said nearly one in six AI Mode queries are non-text, using voice or images. Multimodal searching through Google Lens and voice is becoming a normal way to search, especially on phones.

Google search advertising statistics

15. US search advertising revenue reached $114.2 billion in 2025

The IAB/PwC Internet Advertising Revenue Report (April 16, 2026) puts US search advertising revenue at $114.2 billion in 2025, up 11% year over year, slower than the 15.9% growth seen in 2024. Social media ($117.7 billion) narrowly overtook search as the largest digital ad channel. With roughly nine in ten searches happening on Google, most of that budget is spent on Google Ads.

What do these Google search statistics mean for your website?

Google is still where almost all searching starts, but fewer searches end with a visit to a website. Informational content is the most exposed to AI Overviews, while branded and commercial searches still send clicks. A distinctive brand name that people search for directly is therefore more valuable than ever.

If you are choosing a name, check that the domain and social handles are free with the namechk domain and username checker, or try the brand name generator. For tactics, see our SEO statistics, and for facts about the company itself, our Google statistics and facts.

How we compiled these statistics

We used Google’s own earnings remarks for usage figures, StatCounter for market share, Pew Research Center and SparkToro (Similarweb panel data) for click behavior, Ahrefs’ published CTR studies and the IAB/PwC report for ad revenue. Google no longer publishes a total daily search count, so we did not include one. All data is as of October 2026; older statistics were removed when no current source existed.
