Chinese (Simplified) vs. Traditional: Which Script for Website Translation?
Use Simplified Chinese for mainland China and Singapore; use Traditional Chinese for Taiwan, Hong Kong, and Macau. Most businesses targeting China start with Simplified only, but serving all major Chinese-speaking markets requires both scripts.
If you are translating a website for Chinese-speaking users, the script choice is dictated by geography. Simplified Chinese is the official written standard in mainland China and Singapore. Traditional Chinese is the standard in Taiwan, Hong Kong, and Macau. The two scripts are not interchangeable; readers in each region expect content in their local script, and using the wrong one signals unfamiliarity or disregard for the market.

| SEO & search behavior | Baidu, Sogou, 360 Search; Simplified queries | Google HK/TW, Yahoo Taiwan; Traditional queries |
| Takeaway | Start here for maximum reach in China | Required for credibility in Taiwan/HK/Macau |
Why the script choice matters
Chinese is a single spoken language family (primarily Mandarin) with two distinct written standards. The split originated in the 1950s when the People's Republic of China introduced simplified characters to boost literacy. Taiwan, Hong Kong, and Macau retained the traditional forms. Today, the difference is not just visual—it extends to vocabulary, idioms, and even punctuation conventions. A website that serves only Simplified Chinese will look foreign to a user in Taipei, just as a Traditional-only site will feel alien in Beijing.
How the scripts differ in practice
Character forms
Simplified characters reduce stroke counts and merge some traditional characters into single forms. For example, the traditional character for "dragon" is 龍; the simplified is 龙. The traditional "country" is 國; simplified is 国. These are systematic changes, but they are not algorithmically reversible in all cases—some simplifications merged distinct traditional characters, so automatic conversion can produce errors.
Vocabulary and terminology
Beyond character shapes, the two regions developed different terms for modern concepts. Common examples:
- Software: 软件 (Simplified) vs. 軟體 (Traditional)
- Server: 服务器 (Simplified) vs. 伺服器 (Traditional)
- Internet: 互联网 (Simplified) vs. 網際網路 (Traditional)
- Mobile phone: 手机 (Simplified) vs. 手機/行動電話 (Traditional)
- Default: 默认 (Simplified) vs. 預設 (Traditional)
Using mainland vocabulary in a Traditional Chinese site (or vice versa) reads like a poor machine translation. Professional localization adapts terminology, not just characters.
Punctuation and formatting
Traditional Chinese in Taiwan often uses full-width punctuation and vertical text layouts for certain contexts. Hong Kong mixes Traditional characters with some Cantonese-specific written forms. Simplified Chinese uses standard horizontal left-to-right layout with simplified punctuation rules. These details affect perceived quality.
Market sizing and prioritization
Mainland China's internet user base exceeds 1 billion. Singapore adds roughly 5 million. Taiwan, Hong Kong, and Macau combined represent about 30 million users with high purchasing power. If resources are limited, most businesses start with Simplified Chinese to capture the largest addressable market. However, skipping Traditional Chinese means excluding affluent markets in Taiwan and Hong Kong where users expect native-script content and often have higher per-capita spending.
SEO implications
Search engines index content by script. Baidu (China's dominant search engine) crawls and ranks Simplified Chinese pages. Google Hong Kong, Google Taiwan, and Yahoo Taiwan index Traditional Chinese. If you publish only one script, you are invisible on the other region's search engines. Automatic script conversion does not solve this—search queries are script-specific, and keyword research must be done separately for each market.
Technical implementation options
Separate language codes
Use correct IETF language tags: zh-CN (Simplified, China), zh-SG (Simplified, Singapore), zh-TW (Traditional, Taiwan), zh-HK (Traditional, Hong Kong), zh-MO (Traditional, Macau). Do not use generic zh—it defaults to Simplified in many systems and breaks hreflang targeting.
hreflang and sitemaps
Declare each script version with hreflang annotations so search engines serve the right version to the right user. Example:
<link rel="alternate" hreflang="zh-CN" href="https://example.com/zh-CN/" />
<link rel="alternate" hreflang="zh-TW" href="https://example.com/zh-TW/" />
<link rel="alternate" hreflang="zh-HK" href="https://example.com/zh-HK/" />Content management
Maintain separate translation memories and glossaries for each script. Do not rely on automated character conversion (e.g., OpenCC) as a substitute for human review—conversion tools handle character mapping but cannot fix vocabulary, tone, or regional idioms.
Common mistakes
- Auto-converting Simplified to Traditional (or vice versa) and publishing without review. This produces readable but unnatural text with wrong terminology.
- Using a single "Chinese" translation for all markets. Users in Taiwan and Hong Kong notice immediately and trust the brand less.
- Ignoring Cantonese written forms in Hong Kong. Formal written Chinese in HK uses Traditional characters, but colloquial content may use Cantonese-specific characters (e.g., 喺 for "at/in", 係 for "is"). Decide whether your HK content is formal written Chinese or colloquial Cantonese.
- Assuming Singapore uses Traditional Chinese. Singapore officially uses Simplified Chinese since 1976.
- Neglecting font fallbacks. Some fonts lack full Traditional character coverage; test rendering on target devices.
Decision framework
- Identify target markets. List the specific countries/regions you serve or plan to serve.
- Map each market to its script. China/Singapore → Simplified. Taiwan/HK/Macau → Traditional.
- Prioritize by revenue potential and traffic. Start with the script covering your largest addressable audience.
- Budget for separate localization. Allocate translation, review, and QA resources per script, not per "language."
- Set up technical infrastructure. Configure hreflang, language selectors, and CMS locales for each script variant.
- Conduct script-specific keyword research. Do not translate keywords; research them natively in each market.
- Launch, measure, iterate. Track engagement, conversion, and search visibility per script variant.
When you might need both scripts from day one
- Global SaaS or ecommerce launching simultaneously in China and Taiwan/HK.
- Brands with existing customer bases in both script regions.
- Regulated industries (finance, healthcare) where trust signals require native-script compliance.
- Marketplaces or platforms where user-generated content spans both regions.
Limitations of this guidance
- This article covers written script choice for website translation. It does not address spoken language variants (Mandarin vs. Cantonese audio, video dubbing, or voice UI).
- Overseas Chinese communities (e.g., in the US, Canada, Southeast Asia) may use either script depending on origin and generation. Audience research is needed for diaspora markets.
- Legal requirements for specific industries (e.g., product labeling in China) may mandate Simplified Chinese regardless of your website strategy.

FAQ
Can I just use Google Translate to convert between scripts?
No. Machine conversion handles character mapping but produces wrong vocabulary, unnatural phrasing, and regional mismatches. It is acceptable for internal reference, not for publishing.
Do I need separate translations for Taiwan and Hong Kong?
Both use Traditional Chinese, but vocabulary differs (e.g., Taiwan uses "大眾運輸" for public transport; HK uses "公共交通"). For high-stakes content, localize separately. For informational content, a single Traditional Chinese version with Hong Kong review often suffices.
What about Singapore—do they read Traditional Chinese?
Singapore officially adopted Simplified Chinese in 1976. Schools teach Simplified. Older generations may read Traditional, but the standard for websites and official content is Simplified.
How much does it cost to maintain both scripts?
Roughly 1.5–1.8x the cost of a single script, not 2x, because translation memory leverage and shared project management reduce marginal cost. The main added expense is separate review and QA.
Will users in Taiwan understand Simplified Chinese?
Many can read it with effort, but it creates friction, lowers trust, and hurts conversion. It signals that you did not invest in their market.
What language code should I use for a generic "Chinese" selector?
Do not use a generic code. Offer explicit choices: "简体中文" (Simplified) and "繁體中文" (Traditional), optionally with region sub-options (China, Taiwan, Hong Kong).
