Choosing a Domain Name: The Iron Rules of Brand Domains
Chapter 2: Search Fundamentals · Question 18
A domain name is a brand's "house number" on the internet. Choose the wrong domain, and at best you spend ten times more on promotion; at worst you're forced to buy it back at great expense—everyone in the industry knows how much JD paid when it switched from 360buy.com to jd.com. It's 2026 now: has the logic of domain selection changed? Yes, but the iron rules haven't.
First, the history: classic cases of domain selection
| Brand | Domain evolution | Commentary |
|---|---|---|
| Baidu | baidu.com | The benchmark for pinyin domains, one of the most successful domain strategies of the PC era |
| JD | 360buy.com → jingdong.com → jd.com | Three evolutions, ultimately returning to minimalism. The early domain was impossible for users to remember, and changing domains came at a huge cost |
| 360 Search | so.com | The domain is the pinyin for "search," but the brand is called "360 Search," so users have to search "360 Search" to find it—a cautionary tale of domain-brand mismatch |
| Xiaomi | mi.com | A minimalist two-letter domain, globally usable, with extremely high brand recognition |
| Pinduoduo | pinduoduo.com | A three-syllable pinyin domain—long, but fully consistent with the brand, so users won't misspell it |
Core takeaway:A good domain = trademark = brand. Only when all three are unified can you save enormous advertising costs. When the domain, trademark, and brand name are unified, users can find you by searching just one term, and your ads only need to promote one word.
The five iron rules of domain selection in 2026
Iron Rule 1: If you can choose .com, don't use .cn
.com is the globally accepted "hard currency," with the highest user trust and no search engine discrimination. .cn works domestically, but it's a disadvantage overseas. Unless .com is taken and buying it back is hopeless, stick with .com.
Iron Rule 2: Before finalizing the brand name, check the domain and trademark first
Many founders think up a brand name first, then go to register the domain and trademark, only to find everything is taken. The correct order:
- Come up with 3-5 candidate brand names
- Simultaneously check domain availability (Alibaba Cloud/GoDaddy) + trademark databases (China Trademark Office/WIPO)
- Prioritize the option where you can secure all three: domain + trademark + brand name
- Once decided, register the domain and apply for the trademark immediately—don't wait even a day
Iron Rule 3: For Chinese brands, prefer pinyin, then initial-letter combinations
For Chinese users, pinyin is the most natural input method:
- Full pinyin: suitable for brands of 2-3 characters (such as baidu, taobao, douyin)
- First letters：Suitable for brands with 3 or more characters (e.g., jd = JD, wy = NetEase → actually uses 163.com)
- Bottom line: do not exceed a full pinyin combination of 5 Chinese characters (pinduoduo is already the limit)
Rule Four: English brands should use English words directly
If your brand targets the international market or is itself an English name, use English words or combinations directly: Apple, Nike, Notion. Don't force pinyin just for the Chinese market.
Rule Five: Avoid these pitfalls
- ✗ Mixing numbers and letters (e.g., hao123, 51job) — this pattern is outdated by 2026, and the memory cost for users is high
- ✗ Hyphens (e.g., my-brand.com) — looks unprofessional and easy to mistype
- ✗ Non-mainstream suffixes (e.g., .xyz, .io, .top) — C-end users don't trust them; acceptable for B-end but only within the tech circle
- ✗ Cybersquatting on domains related to others' brands — enormous legal risk; trademark law protection covers the domain field
The new variable in 2026: Are domains still important?
Some say "everyone searches within apps now, domains don't matter anymore." That's only half true:
- Search scenarios: domains still matter. When users see search results on Baidu/Google, short and trustworthy domains get higher click-through rates.
- Brand memory: for offline ads and word-of-mouth, a memorable domain = a free traffic entry point.
- Private domain entry: the official website serves as the private domain hub, and the domain is the convergence point for all external traffic.
- The mini-program/App era: direct domain entry scenarios have indeed decreased, but SEO, brand trust, and corporate email (name@brand.com) still require a good domain.
Practical recommendations
- Check right now: open Wanwang (wanwang.aliyun.com) and check .com availability for your brand name's pinyin, initials, and English combinations. If taken, assess the buyback cost — buying a good domain early saves money.
- Lock down the domain, trademark, and WeChat Official Account name simultaneously: the standard pre-launch action for brands in 2026 is to register the domain + submit the trademark application + register the same-nameWeChat Official Accounts/WeChat Channels; unifying all three is the best SEO foundation.
- Old domains have value: if you can buy an old domain with historical authority and no bad history (registered 5+ years, with a normal site-building record), Baidu indexing speed will be much faster than a brand-new domain.
