Chinese SEO Guide: Baidu, Simplified Chinese and Hosting

Short answer: Chinese SEO starts with a decision about which audience you want, because mainland China, Taiwan, Hong Kong and Chinese-speaking communities elsewhere use different scripts, words, search engines and rules. Create real Chinese pages for the chosen market, use correct hreflang codes, research keywords with native speakers, and check hosting, speed and legal requirements early. For mainland China, plan for Baidu and for access from within the country; for other regions, Google remains central.

“Chinese” is not one market. It covers several written forms and many regions, and a website that treats them as one will disappoint everyone. A page written in Simplified characters for mainland readers may look foreign in Taiwan, where Traditional characters and different vocabulary are normal. A site hosted far from mainland China may load slowly or not at all for visitors there. This guide explains the main decisions, from market choice to measurement, without making claims about market size that would quickly go out of date.

Choose the market before the language

Start by writing down who you want to reach and why. The common options are:

Mainland China: Simplified Chinese, strong local platforms, specific technical and legal conditions.
Taiwan: Traditional Chinese, a market where Google is widely used and local vocabulary matters.
Hong Kong: Traditional Chinese, often with Cantonese influences in spoken language and a mix of Chinese and English in business.
Chinese speakers abroad: students, travellers and communities who search in Chinese from other countries, often with both English and Chinese terms.

Each choice affects the language form, the keywords, the payment options, the support hours and the server location. Starting with one market and doing it well is better than a single “Chinese” version that is a poor fit for all. See how to choose target markets and multilingual vs multiregional sites.

Use the right script and language codes

Simplified and Traditional Chinese are different written forms, not a translation setting. Converting characters automatically is not enough, because vocabulary, product names, spelling of foreign names and tone differ by region. Have a native speaker from the target market write or edit the pages.

For markup, use language codes that identify both script and region where it helps. Common values are zh-Hans for Simplified, zh-Hant for Traditional, and combinations such as zh-CN, zh-TW and zh-HK for regions. Be consistent between the page’s lang attribute, hreflang annotations and the content. The article on Chinese hreflang codes explains the choices in detail, and the hreflang guide covers the general rules, including return links. Test the result with the steps in how to test hreflang.

Plan for Baidu and for Google

In mainland China, Baidu is a major local search engine, and other local platforms also act as search tools for shopping, video and social content. Google’s main search service is not generally the way mainland users search. In Taiwan and Hong Kong, Google is commonly used. This means your technical work depends on the target market:

For mainland China, register your site in Baidu’s webmaster tools, verify ownership, submit your sitemap and read the guidelines. Tools and interfaces may be in Chinese, so involve someone who reads it.
For Taiwan and Hong Kong, follow normal Google practice and use Search Console.
For overseas Chinese speakers, check Google first, and add local platforms if your audience uses them.

Search engines differ in how well they handle scripts, frames, hidden content and heavy JavaScript. If a page depends on scripts to show its text, test what the target engine can see. Plain HTML with clear headings, titles and descriptions is the safest base. See international search engines beyond Google and JavaScript SEO basics.

Do keyword research in Chinese

Chinese text has no spaces between words, and search engines split queries differently from how a translator would. Brand and product names may be searched in English, in Chinese characters or in a phonetic form. Searchers may also use abbreviations and slang that a dictionary does not show. Build your list from:

Search suggestions and related searches in the engine you target.
Customer questions, chat logs and sales notes in Chinese.
Competitor titles and headings that rank for your topic.
Forums, reviews and social posts where your audience describes problems in their own words.
Review by a native speaker who knows the industry.

Decide how to present your brand: the original name, a Chinese name or both. Use the same form everywhere and mention the other form once so that people who know either can find you. See multilingual keyword research and transliteration and SEO.

Check hosting, speed and access

Server location and network conditions matter more for China than for most markets. Pages that load many resources from foreign servers may be slow or may fail to load for some users. Test your pages from inside the target region with local testing services or with the help of a partner there. Reduce third-party scripts, fonts and embeds, since some well-known services are not available in all regions. Serve text and critical files from the same domain where possible, and make sure that a failing script does not block the rest of the page.

If you target mainland China with a site hosted there, there may be legal requirements for registration, so check them with a qualified adviser before you plan the launch. Do not assume that a global content delivery setup will work unchanged. See hosting and CDN for international SEO and third-party scripts and speed.

Write for local habits and trust

Chinese-speaking users expect content that fits local ways of shopping and deciding. Mobile use is very high, so design for small screens first. Payment options, delivery methods, customer service channels and invoices should match local practice. Show a phone number or chat route in local hours, and explain returns and warranties clearly. Use local formats for dates, numbers, currencies and addresses; see local formats and local currency prices.

For fonts, choose a family that includes the needed characters and test it on common devices. Large font files slow the page, so use subsets and load them carefully; see web fonts and page speed. Avoid mixing Simplified and Traditional characters in one page unless you have a reason, and check that images with text have Chinese versions and alt text.

Structure URLs and site versions

Give the Chinese version its own addresses so that each language and region can be indexed and linked. A language folder such as /zh/ or /zh-hans/ is easy to maintain, while a separate domain may suit a bigger project with local hosting. Avoid showing different languages at one address based on the visitor’s location, and avoid automatic redirects that block people or crawlers from other versions. Link the versions to each other with a visible language switcher. See country domains, subdomains and subfolders, language redirects and language switchers.

Measure and audit

Report on the Chinese version separately. Track impressions, clicks and indexed pages in Search Console for Google, and in Baidu’s own tools for Baidu. Compare the pages you meant to publish with the pages that are actually indexed. Check hreflang return links, wrong language attributes and broken language versions after each release. Site SEO AI Audit has a Languages area for exactly these checks, and the first audit of up to 200 pages is free. For the full launch process, see how to launch a new language version.

Common mistakes to avoid

Treating all Chinese readers as one group. Script, vocabulary and habits differ by region, so one page rarely fits all.
Relying on machine translation alone. Unchecked output often sounds unnatural and mistranslates product terms; see machine translation and SEO.
Ignoring speed from the target region. A page that loads well in your office may be slow where your customers are.
Leaving menus, forms and error messages in English. A mixed page signals low effort and increases drop-off.
Launching everything at once. Start with the home page, the main product or service pages and the contact page, measure for a few weeks and then expand.

A short glossary of approved Chinese terms for your products, features and brand makes the work consistent across writers, translators and support staff, and it helps search engines connect your pages with the topics you want to be known for.

The bottom line

Chinese SEO is several projects under one name. Pick the market, choose the script and language code that fit it, work with native writers, plan for the search engines your audience actually uses, and test speed and access from the target region. Then measure each version on its own and fix problems before expanding.

FAQ

Should I use Simplified or Traditional Chinese?

Use Simplified for mainland China and Traditional for Taiwan and Hong Kong. If you serve several regions, create separate versions with native review.

Can I rank in China with a Google-focused site?

Not reliably in mainland China, where local engines dominate and access conditions differ. For Taiwan and Hong Kong, Google practice applies.

Which hreflang code should I use for Chinese?

Use zh-Hans or zh-Hant for script, or region codes such as zh-CN, zh-TW and zh-HK where they match your versions. Keep them consistent with the page’s lang attribute.

Is automatic character conversion good enough?

No. It does not handle regional vocabulary, names or tone, so a native editor from the target market should review every important page.

Do I need a local server?

It depends on the market and the rules that apply to you. Test speed from the region, and ask a qualified adviser about legal requirements before choosing hosting for mainland China.
