Why Baidu is so important in China?

If you want to sell in China, you cannot skip Baidu. It has been the top search engine in the country for over 20 years, and in 2025 it still answers most of the searches Chinese consumers type every day. The interesting part is not that Baidu is big. It is that Baidu changed a lot in the last 18 months, and most foreign brands have not noticed. This article is the simple, honest version of why Baidu still matters and how you actually use it now.

Baidu in numbers, 2025 to 2026

Let me give you the figures first, because numbers settle most arguments.

• China had 1.125 billion internet users by the end of 2025, with 80.1% of the population online. That is the official CNNIC count.
• 777 million people in China use a search engine, about 69% of all netizens. Search was the fastest growing online sector of the year.
• 99.4% of Chinese internet users are on mobile. If your Baidu pages are not built for a phone, you are invisible to almost everyone.
• Baidu’s market share climbed through 2025 and sat above 60% across all devices by late 2025, per StatCounter. On some months it ran near 64%.
• By mid-2025, more than half of Baidu mobile search result pages showed AI-generated answers, and that figure kept rising. The blue links you remember are being replaced by AI summaries.

So the old line is still true. Baidu is the search engine in China. But the way it works in 2025 is closer to an AI answer machine than to the Baidu of five years ago.

What is Baidu, really

People outside China call Baidu “the Google of China.” That nickname is lazy. Baidu does run the biggest Chinese-language search engine in the world, but it is also a set of products that shape what Chinese consumers trust:

• The search engine, which now answers many queries with AI text instead of a plain list of sites.
• Baidu Baike, an encyclopedia like Wikipedia. A brand page here builds instant credibility.
• Baidu Tieba, one of the largest forum communities in the country.
• Baidu Zhidao, a questions-and-answers board where buyers ask before they buy.
• ERNIE, Baidu’s own AI model, which feeds the answers inside search.

Chinese shoppers do their homework on net before they spend. They open Baidu, they read Baike, they scan a Tieba thread, they check Zhidao. If your brand is missing from all of those, you do not exist to them. That is the core reason Baidu is the right internet media to reach the consumers you are hoping for.

The thing nobody tells foreign brands: Baidu went AI-first

Here is the insider point. In January 2025 Baidu rolled AI answers into the top of its search results. Within six months over half of mobile result pages carried AI-written summaries built on its ERNIE model. ERNIE Bot itself passed 200 million monthly active users by early 2026.

What does that mean for you in plain terms? A Chinese user types a question, Baidu writes a paragraph answering it, and your link may never get a click. The game is no longer only “rank number one.” The new game is getting your brand quoted inside the AI answer. We call this GEO, generative engine optimization, and most Western agencies are not doing it yet for the Chinese market.

To get picked up by Baidu’s AI, you need clear, factual Chinese content, a strong Baidu Baike entry, consistent mentions across Tieba and Zhidao, and structured pages that the model can read. It rewards brands that look like a trusted source, not brands that stuff keywords.

Baidu SEO is still the cheapest way into China

Companies keep discovering how big the Chinese market is. The hard part is getting in. The language is a wall, the rules are strict, and the channels are not the ones you know at home. Baidu SEO is the most affordable bridge across that wall.

• Pick the right Chinese keywords. A direct translation of your English terms almost never matches what people actually search. Real keyword work can multiply your traffic.
• Host inside or near China. A slow site loses Baidu rankings. Speed is part of the ranking.
• Write in simplified Chinese for a Chinese reader. Localizing the content, not just the words, is what wins trust and sales.
• Build the off-page signals. Baike, Zhidao and Tieba mentions tell Baidu you are real.

A well-localized site also pulls extra traffic from Chinese-speaking buyers in other countries. Done right, Baidu SEO pays back hard in a market this size. You can see how we approach it on our Baidu SEO and SEM service page and across our full list of services.

SEO and ads: use both

SEO builds long-term trust, but it takes months. Paid search buys you the top of the page today. Most brands that win on Baidu run both. You use Baidu ads to test which keywords convert, then pour that learning into your SEO so the free traffic keeps coming after the ad budget stops. If you want the paid side, start with Baidu advertising. If your goal is selling product, pair search with e-commerce in China, because a Baidu search often ends on Tmall or JD.

Baidu is wired into how China lives

Baidu matters because it is connected to everything. It sits next to Weibo, Alibaba and the rest, and it links buyers, sellers, suppliers, schools and students. A few tools worth knowing:

• Baidu Tieba: one of the biggest forums in China. People type a keyword and start a discussion. Getting your brand talked about here, in a real way, pays off.
• Baidu Baike: a web encyclopedia like Wikipedia. Censorship rules apply, so stay inside the tight restrictions when you build your entry.
• Baidu Zhidao: a questions-and-answers board. A good way to get your company in front of buyers who are deciding right now.
• Baijiahao: Baidu’s news platform, where media and brands publish articles and news.
• Baidu video, tied to iQiyi.

Baidu is not Google, and that is the point

People always called Baidu China’s Google. It was never the same product, and with Google out of mainland China, Baidu has no real rival in search there. Chinese and Western users also have different habits and different expectations online, so even when Google was present it could not beat Baidu on its home turf.

The practical takeaway: do not copy your Google playbook and expect it to work. Baidu ranks Chinese content, hosted fast, on a verified domain, with strong off-page signals and, now, AI-friendly structure. The brands that treat Baidu on its own terms are the ones that win.

Frequently asked questions

Is Baidu still the most used search engine in China in 2025?

Yes. Baidu held above 60% of search across all devices in China through late 2025, per StatCounter, and it remains the largest Chinese-language search engine in the world. It grew in 2025 after adding AI answers to its results.

How is Baidu using AI in search now?

Baidu put AI summaries at the top of its results in January 2025. By mid-year, more than half of its mobile result pages showed AI-generated answers powered by its ERNIE model. Many users get a written answer without clicking a link, so brands now optimize to be quoted inside that answer, not only to rank.

Do I need a Chinese website to rank on Baidu?

For real results, yes. Baidu favors content written in simplified Chinese, hosted on a fast server in or near China, ideally on a domain with an ICP license. An English site translated word for word almost never ranks well.

How much does Baidu SEO cost for a small brand?

It varies with your goals, but you do not need a huge budget to start. A one-time audit plus a focused content plan can get a small brand moving. Ads and SEO together usually give the best return because ads show you which keywords actually convert.

Is Baidu mobile-first?

Completely. About 99% of Chinese internet users go online via mobile, so Baidu ranks and displays for phones first. A site that loads slowly or breaks on a phone will lose visibility.
