Knowing the search engine market share helps decide where to invest: in most countries, optimizing for Google covers the vast majority of searches, while some markets (Russia, China, South Korea) need local engines. This page gathers the latest figures with their source and date, and explains what they mean for SEO and for visibility in AI answers. For how engines work, see how search engines work.

What is the search engine market share in 2026?

Source: StatCounter Global Stats, September 2026, for worldwide, United States and mobile figures.

Why does Google dominate?

Default placement on Android and in Chrome and Safari, a very large index, and decades of habit. On mobile, where most searches happen in many countries, its share is even higher. For most businesses, this means Google's rules and tools (Search Console, its documentation) remain the reference for SEO.

Where does Bing matter?

Bing has a larger share in the United States and on desktop, where it is the default on Windows and in Edge. It also powers other engines and services, so optimizing for Bing reaches more than its own share. Our guides to Bing SEO and Bing Webmaster Tools cover the setup.

Which countries need other search engines?

• Russia and some neighboring countries: Yandex holds a large share.
• China: Baidu leads, and Google is not accessible.
• South Korea: Naver remains a major player alongside Google.
• Privacy-focused audiences: DuckDuckGo, Ecosia and others have small but loyal users.

How do AI assistants change the picture?

Market share tables count classic search engines, but buyers increasingly ask assistants. OpenAI's CEO announced more than 800 million weekly ChatGPT users at DevDay in October 2025, as reported by TechCrunch, and Google reported more than 2 billion monthly users of AI Overviews inside its own results. These answers draw on web pages, so search share and AI visibility are now linked. Our GEO statistics gather the key figures, and GEO vs SEO explains how to work on both.

What does it mean for your SEO?

1. Optimize for Google first in most markets; it covers the bulk of searches.
2. Register with Bing Webmaster Tools: little effort for extra reach, especially in the US.
3. Add local engines only where your market uses them.
4. Track AI visibility: mentions in ChatGPT, Gemini and Perplexity, a channel no market share table shows.

The bottom line

Google keeps about nine searches in ten worldwide, Bing matters on desktop and in the US, and AI assistants add a new layer that market share tables do not count.
