China's Search Evolution: Baidu, AI Models, and B2B SEO Strategy
Map your B2B SEO strategy to Baidu, Bing, and other Chinese search engines, and incorporate AI model integration.
Align your SEO assets for Baidu and integrate with emerging LLMs like DeepSeek to capture B2B traffic.
Summary
Baidu remains the dominant mobile search engine with ~70% share, powering 724 million monthly active devices as of early 2026, and continues to be the primary channel for B2B research. The platform is integrating DeepSeek into its search experience while its own Ernie (Wenxin) model remains a formidable competitor. Chinese tech giants are increasingly open‑source their models, releasing new LLMs every few months that specialize in different domains. Despite the narrative that web search is dead, B2B buyers still rely on Baidu, Bing, and other search engines for verified, authoritative sources, generating higher conversion rates than in many Western markets.
The search ecosystem is tiered: traditional web search (Baidu, Bing, Haosou, Sogou, Google) dominates authority‑driven queries; social discovery (WeChat, Xiaohongshu, Douyin, Kuaishou, Weibo, Bilibili) fuels inspiration‑based searches; e‑commerce (Taobao/Tmall, JD.com, Pinduoduo, Douyin Mall, Xianyu) handles transactional intent; and generative AI (Doubao, ByteDance) provides reasoning‑based answers that synthesize information. B2B marketers must therefore map their SEO assets to Baidu and other Chinese search engines while integrating emerging LLMs to capture intent‑driven traffic.
