A New Landscape for China's AI Search Market
By the first half of 2026, the competitive landscape of China's AI search market has become relatively clear:
- Baidu Ernie (Wenxin): 300M+ monthly active users. Built on Baidu's search ecosystem, it is the largest AI search entry point by user volume in China.
- DeepSeek: 80M+ monthly active users. Renowned for its technical capabilities and deeply penetrated among professional users and developers.
- Kimi (Moonshot AI): 35M+ monthly active users. Strong at processing long documents, with an edge in content creation and research scenarios.
- Doubao (ByteDance): Over 100M Q&A interactions per day. Backed by the Douyin ecosystem, it enjoys a unique advantage in content distribution.
- Yuanbao (Tencent): Built on the WeChat ecosystem, with high penetration among enterprise users.
Key data point: Baidu's latest quarterly report shows that AI-generated content (AI Overview-style features) now accounts for more than 40% of its search results pages. In other words, one in every two Baidu search results involves AI content.
What Makes Chinese GEO Optimization Different
Optimizing for domestic AI search differs from Google GEO in several important ways:
Difference 1: Baidu authority is the foundation
The content data sources of domestic AI engines (Ernie in particular) draw heavily from Baidu's index. The quality of Baidu indexing directly affects citation rates in domestic AI. Baidu SEO and domestic GEO optimization are two sides of the same set of actions.
Difference 2: WeChat Official Account content is heavily cited
Doubao (ByteDance) and Yuanbao (Tencent) have deep data partnerships with the WeChat content ecosystem. High-readership WeChat Official Account articles are an important content source for these two types of AI engines.
Difference 3: Zhihu is the single highest-authority source
In citations from DeepSeek and Kimi, Zhihu answers appear far more frequently than ordinary web pages. A highly upvoted Zhihu answer may be 5–10 times more likely to be cited by domestic AI than an independent blog article of comparable quality.
Differentiated Strategies for Different Platforms
Ernie (Wenxin): Optimizing Baidu SEO Is Fundamental
Ernie's content sources rely heavily on Baidu's search index, so the most effective way to improve your Ernie citation rate is to improve your Baidu SEO.
Key actions:
- Use the "active push" API in Baidu Webmaster Platform to ensure new content enters the Baidu index quickly.
- Monitor your content's "mobile usability" in Baidu Search Resource Platform (Baidu's mobile-first indexing has been fully implemented).
- When testing Ernie citations, pay particular attention to "Baidu Baijiahao" content—Baijiahao articles are cited by Ernie at a noticeably higher rate than ordinary external sites.
DeepSeek: Expertise and Data Are Key
DeepSeek's users are primarily technical professionals and researchers, and the platform shows a clear preference for deep, expert content.
Content strategy:
- Publish data-dense articles (with charts, data tables, and statistical analysis).
- Cite first-hand research data rather than merely restating other sources.
- Include code examples in technical content—DeepSeek cites technical tutorial-type content at a very high rate.
Kimi: Long-Form and Comprehensive Analysis
Kimi's technical hallmark is its ultra-long context processing capability, and when answering complex questions it tends to cite comprehensive, fully covered long-form articles.
Content strategy:
- Publish "complete guide"-style articles that cover every dimension of a topic (3,000+ words).
- Keep the article structure clear, with a table of contents and section navigation.
- Provide a "further reading" list at the end of the article, linking to other in-depth content on the same topic.
Chinese GEO Tracking Tools
Dedicated GEO monitoring tools for Chinese AI search are still in their early stages, but the following methods allow for manual tracking:
- Monthly systematic testing: Search 5–10 core keywords separately in Ernie, DeepSeek, Kimi, and Doubao, and record whether your content is cited.
- GA4 monitoring: Set up referral traffic monitoring for traffic from yiyan.baidu.com, deepseek.com, and kimi.moonshot.cn.
- Brand term monitoring: Search your brand name to understand whether AI's definition of your brand is accurate.
Why the Timing Window Matters
GEO optimization for domestic AI search is currently in an early dividend period. Compared with Google GEO optimization (where competition is already quite fierce), the supply of content optimized for domestic AI platforms remains very limited.
Sites that position themselves now have a chance to establish a clear citation advantage in domestic AI search within 6–12 months. This window will not stay open for long.
