What Is Sogou?
Sogou is China's second-largest search engine, acquired by Tencent (the company behind WeChat) in 2021. It holds approximately 15% of China's search market. Sogou's key differentiator is its deep integration with WeChat — it can search content within WeChat's ecosystem (Official Accounts, Mini Programs, articles) that is inaccessible to Baidu. Sogou is also known for its input method (Sogou Pinyin) used by hundreds of millions of Chinese users.
Why Sogou Matters for SEO
Sogou is essential for reaching Chinese audiences through WeChat's ecosystem. If your brand has a WeChat Official Account, Sogou indexes that content and makes it searchable. Sogou's search results include dedicated WeChat content sections. For businesses active on WeChat (critical for China marketing), Sogou optimization ensures your WeChat content is discoverable beyond the app itself.
