Baidu holds the majority of search in mainland China, and its ranking logic was shaped by a market Google never operated in. The fundamentals rhyme with Google — crawl, index, rank — but the details that decide outcomes are different enough that a Google playbook applied unchanged will underperform.
The structural differences
- Hosting inside mainland China, with an ICP licence, materially affects crawl rate and ranking. Latency across the border is a real cost.
- Simplified Chinese content written for Chinese readers outperforms translated text, and Baidu is good at telling the difference.
- Baidu’s own properties — Baijiahao, Baike, Zhidao, Tieba — occupy a large share of results.
- Enforcement is by named algorithm, published in advance, rather than by silent update.
What transfers
Crawlability, site architecture, page speed, internal linking and content quality all matter in the same direction. The difference is emphasis and infrastructure, not principle.
How we apply this
We tell clients entering China that the first two decisions — hosting location and ICP licence — outweigh everything we can do on the page. A site hosted abroad without a licence is competing with a permanent handicap, and no amount of optimisation removes it.
