Baidu SEO shares the basics of Google SEO, such as useful pages and clean technical foundations, but it adds three differences that catch overseas businesses out: where a site is hosted and whether it holds an ICP number, the need for genuinely Chinese-language content, and the fact that Baidu publishes less detail than Google about how it ranks. This is an overview, not a ranking guide.
What stays the same
Search engines everywhere reward pages that clearly answer a query, load reliably and are easy to crawl. A site with clear structure, descriptive page titles, working links and original content has a head start on any engine. If you already follow good practice for Google, you are not starting from zero.
Difference 1: Hosting and the ICP number
An ICP filing (known in Chinese as bei’an) is a registration that China requires for websites operating inside the country. Cloudflare’s documentation explains that sites with their own domain that operate in China need to be licensed, whether hosted in Mainland China or delivered there through a CDN. Public sites must show the ICP number on the home page, and China-based hosting providers are instructed to shut down sites without one, often without notice. The page also says an ICP filing covers informational sites, while sites that sell goods or services need an ICP licence instead (Cloudflare).
For a business based in Australia, this has practical effects:
- Applications are normally made through a hosting or cloud provider in China, and the process involves a China-registered entity or approved applicant type.
- Hosting inside China brings speed for local visitors but also compliance duties.
- Hosting outside China may keep things simpler, but the site may load more slowly for Chinese users.
How much an ICP number directly affects Baidu ranking is a point where published guides disagree, and Baidu’s own position is not something we could confirm. Treat claims of guaranteed ranking boosts with caution, and plan around the clear requirement: if you serve visitors from inside China, check the filing rules with your hosting provider and a qualified adviser.
Difference 2: Language and locale signals
Google’s international guidance says it works out a page’s language from visible content, recommends a separate URL for each language version, and uses hreflang annotations to connect them (Google Search Central). That page covers Google only, so do not assume every point transfers to Baidu. Still, the principles are sensible for any engine:
- Write Simplified Chinese pages for a mainland audience, rather than machine-translating English pages. See localisation versus translation.
- Keep one language per page.
- Give each language its own URL and a visible way to switch.
- Use Chinese titles and descriptions that reflect how people in China search, not literal translations of English keywords.
Difference 3: A different ecosystem
Search habits in China run through several platforms, and brand discovery often happens off a classic search engine. Plan your presence across the channels your audience uses, and keep messaging consistent. The wider planning questions are covered in launching a brand across English- and Chinese-speaking markets.
A planning checklist
| Question | Why it matters |
|---|---|
| Do we aim to serve visitors inside China? | Decides hosting and filing needs |
| Do we sell directly, or only inform? | Informational sites and transactional sites face different licence types |
| Who will write native Chinese content? | Quality and tone drive results |
| Is our domain and hosting plan settled? | Changing later is costly |
| Who owns compliance? | Rules and enforcement change |
What we cannot tell you
Baidu’s ranking behaviour is less documented in English than Google’s, and what circulates online is often vendor marketing. Before committing budget, verify requirements with Baidu’s own webmaster tools and a China-based specialist, and test with a small section of your site first.
If you are earlier in the journey, how Australian brands can reach international audiences is a sensible starting point.
