How does GEO work in Chinese?

Mandarin Chinese is the world’s second most spoken language according to Ethnologue, with more than 1.1 billion total speakers. Yet Chinese is the content language of just 1.3% of websites. English accounts for about half the web despite a comparable number of speakers. This gap between the audience and the amount of public content is the opportunity this guide examines.

The reason is structural: most Chinese-language content lives inside the mainland's walled gardens — WeChat official accounts, Zhihu behind login walls, Baidu's own properties — surfaces that Western crawlers cannot index and Western assistants therefore cannot cite. The Chinese web that ChatGPT, Perplexity and Gemini actually retrieve from is the open slice published in Taiwan, Hong Kong, Singapore, Malaysia and the diaspora.

That open slice is thin relative to a billion speakers — the same mismatch we work with in Hebrew — and the same dynamic follows: few independent sources compete for each answer slot, so a single well-structured, extractable Chinese page can own a category prompt in a way that is nearly impossible in crowded English niches. Corroboration is harder to assemble — but the citation, once earned, faces little competition.

ChatGPT is not officially available in mainland China. OpenAI’s supported-countries list excludes the mainland, Hong Kong and Macau, while including Taiwan, Singapore and Malaysia. A plan for Chinese-language visibility on ChatGPT must account for those limits. It cannot promise official access to a market the provider does not serve.

The real, addressable audience is large on its own terms: Taiwan and the officially served Southeast Asian markets, millions of Chinese speakers across North America, Europe and Australia, and Hong Kong. There OpenAI restricts access, but Perplexity works and Gemini has been natively available since March 2026 — so Hong Kong's Traditional-Chinese content still feeds the corpus every assistant retrieves from. Mainland users on VPNs do reach these assistants too; we treat that as unmeasurable upside, never as a promised market.

Google is moving in the same direction: AI Overviews added Chinese in the May 2025 expansion to more than 200 countries and territories and over 40 languages. Chinese-language queries on the open web are getting AI-composed answers across every major surface — the question is whose pages those answers cite.

Chinese is one language with two writing systems. Simplified characters serve the mainland, Singapore, Malaysia and most of the recent diaspora; Traditional characters serve Taiwan and Hong Kong. The same brand claim rendered in each script is, to a retrieval system, two different strings on two different pages — and a Latin or pinyin rendering of the brand name makes a third form. Models must learn that all three are one entity, or citations split between half-known names and none accumulates authority.

The mechanics are unglamorous but decisive: hreflang that distinguishes zh-Hans from zh-Hant so crawlers serve the right script to the right market, structured data that declares the Simplified, Traditional and Latin names as alternates of one organization, and independent Chinese sources that mention the Latin name alongside the characters. Because the open Chinese corpus is small, a handful of consistent cross-script descriptions moves entity recognition further than dozens of links would in English.

Chinese-language prompts on Western assistants skew heavily toward the situations of people living, studying, shopping or traveling outside the mainland — which makes them unusually commercial. Someone asking an assistant in Chinese from Toronto, Taipei or Singapore is typically comparing services they intend to buy: immigration and education consulting, cross-border e-commerce, diaspora-facing professional services, tourism.

Choose a fixed set of relevant questions for each script and track which businesses and sources appear over time. Simplified and Traditional Chinese need separate measurements because they draw on different sources. The table below illustrates useful commercial categories.

Simplified Chinese is one of our nine native languages, alongside English, Russian, German, French, Italian, Spanish, Hindi and Hebrew — our own site ships every page in it, with correct zh-Hans hreflang and no machine-translation register. We keep the Chinese version of every claim aligned with its English counterpart, because assistants notice when a brand says different things in different languages. Whether you call the discipline GEO, AEO or LLM SEO — we treat the three as synonyms — cross-language consistency is what the assistants reward.

We use a fixed question set and repeat tests in clean, logged-out sessions across ChatGPT, Perplexity and Gemini. Citation rate and share of voice are compared with the starting baseline. For Chinese, results are separated by script and region: Traditional Chinese questions for Taiwan and Simplified Chinese questions for overseas communities draw on different sources. Combining them can hide changes relevant to a particular market.

We start by checking which companies assistants already recommend for Chinese questions in your category, and which script they use. The project scope also reflects where each service is officially available; Western assistants cannot promise access to buyers in mainland China.
