Baidu SEO is the work of getting a website to rank on Baidu, the largest search engine in mainland China. The basics differ from Google: write in Simplified Chinese, make the site load fast inside China, and register the site in Baidu's own webmaster platform. Fast loading usually means mainland hosting, and mainland hosting needs an ICP filing.
Many Google habits still help, such as clear titles, useful content and clean code. But a site that ranks well on Google can be slow or even broken for a visitor in Beijing. This guide covers the parts that are different.
Why does Baidu matter?
Baidu leads the Chinese search market. StatCounter showed Baidu with about 47% of search traffic in China in September 2026, ahead of Bing at about 22%. Google had less than 2%. StatCounter measures page views on sites that use its tracker, so treat these numbers as a rough guide, not an exact count.
The takeaway is simple. If your audience lives in mainland China, Google rankings alone will not reach them. Baidu is the engine most of them use, and it has its own rules.
What is an ICP filing, and do you need one?
An ICP (Internet Content Provider) record is a permit from the Chinese authorities. You need it to host a website on a server in mainland China. There are two main types:
- ICP filing (Bei'an). For sites that share information and do not sell directly.
- ICP commercial license. For sites that sell online or earn money in other direct ways.
Strictly speaking, Baidu can rank a site without an ICP. Chinafy, a company that helps sites load in China, notes that sites hosted outside China can still appear in Baidu results. The catch is speed. Offshore sites often load slowly for users in China, and slow sites struggle to rank. Most foreign companies get an ICP through a Chinese hosting provider or a local partner. Rules change, so ask your provider for the current steps.
How do hosting and speed affect Baidu?
Speed inside China is where many foreign sites fail. Your site may load in one second in Europe and take ten in Shanghai. You have three hosting options:
| Option | Speed in China | ICP needed? |
|---|---|---|
| Mainland China hosting | Best | Yes |
| Hong Kong or Singapore hosting | Often fair | No |
| Hosting in the US or Europe | Often slow | No |
Hosting is only half of it. Google services are blocked in mainland China, so Google Fonts, Google Maps, reCAPTCHA and YouTube embeds may not load. A page that waits on a blocked script can hang for a long time. Host fonts and scripts on your own server or a CDN that works in China. Our guides on faster font loading and slow websites on a fast connection show how to find these slow parts.
How do you write content for Baidu SEO?
Baidu prefers Simplified Chinese, the script used in mainland China. Sinorbis notes that Baidu also prefers it over Traditional Chinese, which is common in Hong Kong and Taiwan. A few rules help:
- Use native writers. Machine translation reads badly and misses the words people really search for.
- Research Chinese keywords. Do not translate your English keywords word for word. Chinese users often phrase searches differently.
- Write a clear title and description. Keep them short, put the main term first, and match what the page offers.
- Keep important text in HTML. Do not hide key content inside images or behind heavy JavaScript.
- Use a mobile-friendly layout. Most searches in China happen on phones.
Expect Baidu's own products near the top of many results. Sinorbis points out that pages from Baidu Baike (an encyclopedia), Baidu Zhidao (questions and answers), Tieba (forums) and Wenku (documents) often rank high. Some brands build a presence there as well as on their own site.
How do you use Baidu's webmaster platform?
Baidu runs its own version of Google Search Console, called the Baidu Search Resource Platform (ziyuan.baidu.com). Many people still call it Baidu Webmaster Tools or "Zhanzhang". The interface is in Chinese, so a browser translation tool or a Chinese-speaking helper makes setup easier.
- Create an account and add your site.
- Verify ownership. WE Interactive recommends the HTML file upload method as the most stable one.
- Submit a sitemap and new links. Baidu's crawler tends to be slower than Google's, so submitting new URLs helps.
- Watch crawl errors and fix pages that fail to load.

How are links different on Baidu?
Links still count, but local links count most. A link from a respected Chinese site sends a stronger signal than many links from foreign blogs. Good sources include Chinese industry sites, partners, local news and the Baidu-owned platforms above.
Stay away from link farms and bought link packages. Baidu has long acted against link spam, just like Google. A few honest local links beat hundreds of cheap ones.
How long does it take to rank on Baidu?
Plan for months, not weeks. A new site needs time for the ICP process, for Baidu to crawl it and for trust to build. In most cases you will see slower indexing than on Google, especially for foreign sites. Track progress in the Search Resource Platform and in a China-friendly analytics tool, since some Google tools do not work well inside China.
Baidu SEO rewards sites that act local. Write in Simplified Chinese, load fast inside mainland China, verify the site with Baidu, and earn links from Chinese sources. Do those four things well and the rest of your normal SEO work starts to pay off.
Frequently asked questions
Can a website rank on Baidu without an ICP license?
Yes, a site hosted outside China can still appear in Baidu results. But it often loads slowly for users in China, and speed affects rankings. Many businesses that take China seriously get an ICP and host in the mainland.
Does Baidu index English websites?
Baidu can index English pages, but it shows them mostly for English searches, which are rare in China. To reach Chinese users, publish pages in Simplified Chinese.
Is a .cn domain required for Baidu?
No. A .cn or .com.cn domain can send a local signal, and Sinorbis notes they are becoming more popular. A fast, Chinese-language site on a .com domain can still rank well.
