Baidu Advertising Rules in 2025: What Foreign Brands Need to Know About China’s Laws

If you’re a foreign brand planning to run ads in China, especially on Baidu, you’ll need more than great creative. China’s digital landscape is governed by one of the strictest advertising laws in the world, with unique rules around what you can say, how you say it, and who you say it to. What might work in the West like bold claims or familiar ad formats can get your campaigns blocked or your account suspended.

From platform-specific regulations to cultural expectations, navigating this space takes local insight and legal awareness. Baidu, China’s leading search engine, is a powerful tool to reach high-intent audiences but only if you follow the rules.

This guide breaks down what you need to know about China’s advertising laws in 2025, how Baidu advertising enforces them, and what foreign brands must do to stay compliant, relevant, and successful in this complex but rewarding market.

Overview of China’s advertising law

If you’re planning to advertise in China, understanding the local advertising law isn’t just a nice-to-have—it’s essential. Originally introduced in 1994 and revised several times since China’s advertising law has become one of the strictest in the world. It’s not just about what you say in your ads, but how you say it, who you say it to, and how those messages are delivered.

Compared to many Western countries, China’s approach is more controlled and closely monitored. Why? 

Because the law isn’t only about marketing it’s also about protecting the public. At its core, China’s advertising law is designed to safeguard consumers, preserve social harmony, and promote responsible brand behavior. 

That means you can’t make exaggerated claims, use superlatives such as “best” or “most effective,” or include endorsements from minors. Even language and imagery that might be seen as too aggressive or misleading can get flagged.

It’s also about guiding how businesses operate in the market. The law aims to create a fair, truthful, and culturally respectful advertising environment. This is especially important in sectors like healthcare, food, and finance, where misleading information can have serious consequences.

Thus, before launching your next campaign, make sure you’re not just thinking creatively—but also legally. Knowing what’s allowed (and what’s not) under China’s advertising law will save you time, money, and the risk of costly penalties. In the sections ahead, we’ll break it all down so you can market with confidence and compliance.

China ad compliance: 4 things every advertiser must know

If you’re planning to advertise in China, there’s more to it than creating catchy slogans or eye-catching visuals. China has strict advertising regulations—and failing to follow them can lead to serious consequences.  Whether you’re running a search ad on Baidu or promoting your products on WeChat or Douyin, staying compliant isn’t optional—it’s essential.

So, what are the key rules every advertiser must keep in mind?

• No false or misleading claims. Under Article 4 of China’s advertising law, you can’t exaggerate your product’s features or make statements that can’t be proven. If it sounds too good to be true, it probably shouldn’t be in your ad.
• Product descriptions must be clear and accurate. Article 8 requires advertisers to ensure that everything they say about a product or service is truthful, understandable, and not misleading. Ambiguous claims or vague language won’t cut it.
• Avoid unrealistic promises, especially time-based guarantees like “delivery in 3 minutes” or “instant results.” These types of claims are often seen as deceptive and can lead to enforcement action.
• Non-compliance can come with real consequences—we’re talking fines, ad account suspension, or even getting blacklisted from major platforms. That’s not a risk any brand wants to take.

The bottom line?

Advertising in China through Baidu ad management is full of opportunity, but it also comes with rules you can’t afford to ignore. Keep these four essentials in mind, and you’ll be in a much stronger position to run effective, trustworthy campaigns that resonate with Chinese consumers.

Baidu ads and the law: What you must know

If you’re planning to advertise in China, Baidu should be at the top of your list. As the country’s leading search engine, Baidu gives you direct access to high-intent users—people actively searching for products, services, and solutions.

That’s what makes Baidu so powerful for brands: it’s not just about visibility, it’s about being there when your customers are ready to act.

But, advertising on Baidu isn’t just about uploading an ad and hitting “go.” Chinese advertising has strict digital advertising regulations, and Baidu works closely with the government to ensure all ads meet these standards. This includes keyword monitoring, content filtering, and tight oversight of claims and messaging.

If your ad doesn’t align with the rules, it won’t be approved—or worse, your account could be suspended. Understanding how to stay compliant is key. Whether you’re using text ads, display or video ads, or Brand Zone placements, each format comes with its own set of guidelines. 

Ads must be accurate, respectful of local laws, and free from misleading claims. Even your landing pages need to follow these rules. For China’s PPC advertising, you’ll need to prepare specific documents, such as business licenses and certificates, especially for any health or financial claims.

Ad approval can take a few days, so build that into your planning timeline. Here, industries like pharmaceuticals, finance, education, and health face tighter restrictions and may require additional permissions.

Key terms in China’s advertising law

If you’re planning to advertise in China using platforms like Baidu, it’s important to understand how the law sees your role and the roles of others involved. China’s advertising regulations are strict, and knowing a few key terms can help you stay compliant and avoid surprises.

Let’s break it down in simple terms:

• Advertiser: That’s you—any individual or business who pays for the ad and decides what it says. You’re responsible for the accuracy and legality of the content.
• Advertising operator: This is usually the agency or platform that helps create or manage the ad on your behalf. They can design, place, or monitor your campaign but are also responsible for ensuring the content follows the law.
• Publisher: These are the media platforms—like Baidu, WeChat, or Red that actually display the ad to the public. They must review ad content and block anything that violates regulations.
• Spokesperson: This refers to any celebrity, influencer, or expert who endorses your product. They can be held liable if the ad misleads consumers or promotes false claims.

Why do these definitions matter?

Because responsibility is shared. If you’re advertising on third-party platforms, you’re not off the hook just because someone else placed the ad. Everyone involved from the brand to the platform to the influencer has a legal obligation.

Understanding these roles helps protect your brand and build trust in China’s competitive digital landscape.

Let’s dive deeper into how this works.

Key provisions of the law: What it says

When a new law rolls out, the legal language can feel overwhelming. But understanding the basics doesn’t have to be complicated. Let’s break down this law into six main sections explained in plain English so you know exactly what it means and why it matters.

• The General Provisions section outlines the purpose and foundation of the law. It sets the tone by explaining what the law is trying to achieve and who it applies to.
• Content Rules define what kind of information or materials are allowed — and what’s off-limits. This ensures that all content stays within acceptable boundaries.
• Conduct Regulations. These focus on how individuals and businesses are expected to behave under this law. Think of it as a guide to what you can and can’t do.
• The Supervision and Management section talks about how the law will be enforced. It explains who’s in charge of monitoring activity, how they’ll do it, and what systems are in place to ensure compliance.
• Legal Liabilities cover what happens if you break the rules. From fines to more serious consequences, this section spells out the risks involved in non-compliance.
• Supplementary Provisions cover all the extra details — like definitions, exceptions, or transitional arrangements — that don’t fit neatly into the other sections but are still important.

By breaking it down this way, the law becomes much easier to understand. Whether you’re a business owner, a content creator, or just someone trying to stay informed, knowing the key provisions helps you navigate with confidence.

Who enforces the rules and how strictly?

When it comes to advertising in China, it’s not a free-for-all. The rules are strict, and knowing who enforces them is just as important as knowing what the rules are.

At the top level, the State Administration for Market Regulation (SAMR) is the main authority overseeing advertising laws and ensuring that content is truthful, fair, and compliant with national standards. They set the rules—and they take violations seriously.

But enforcement doesn’t stop there. Provincial and local government bodies also play a big role. They’re responsible for day-to-day checks, reviewing ads in their regions, and issuing penalties when something goes wrong. This means your ads can be flagged at both national and local levels.

That’s why Baidu has built strict ad review systems to stay in line with these regulations. Every ad goes through an approval process, and certain keywords or categories are automatically banned. Baidu’s internal controls help filter out risky content before it even goes live—protecting both the platform and advertisers.

It’s not just about reaching the right audience — it’s also about playing by the rules. Behind those rules are four key values: order, respect, equality, and truth. These principles shape how ads are created, reviewed, and displayed on platforms like Baidu.

1. Order means your ads shouldn’t disrupt social harmony or go against public interest. Content that feels chaotic, controversial, or misleading can quickly be taken down.
2. Respect focuses on protecting cultural and social standards. That includes avoiding any harm to minors, staying away from sensitive topics, and not misusing national symbols or images.
3. Equality ensures a fair playing field. Baidu doesn’t allow claims like “No. 1 in China” or “the best” if they aren’t backed by verified data. It’s all about avoiding exaggerated, monopoly-style messages.
4. Truthfulness is simple: your ads must be accurate and evidence-based. If you make a claim, you need proof.

Baidu’s ad review filters are strict because they reflect these deeper values. Following them isn’t optional—it’s essential.

Industry-specific regulations and how they impact your ads

When it comes to advertising in China, especially on platforms like Baidu, understanding industry-specific regulations is critical. Not every product or service can be promoted the same way—and getting it wrong can lead to disapproved ads, penalties, or worse, getting banned from the platform.

Let’s start with pharmaceuticals, health, and alcohol. Baidu has strict rules in these categories. You can’t make exaggerated health claims, show certain medical visuals, or promise specific results from using a product. Even keywords are tightly controlled—some terms simply won’t be allowed in your ad copy, no matter how accurate they may seem.

In the education sector, there’s zero tolerance for overpromising. You can’t say your course guarantees exam success, top university admissions, or job placement. Tutoring and certification programs especially come under scrutiny, and Baidu screens these ads carefully to ensure compliance.

Finance and real estate ads also face serious restrictions. Any promise of guaranteed returns or “risk-free” investment is banned. You’re also required to include risk disclaimers in your ad copy. For real estate ads, even location-based phrases like “5 minutes from the subway” can raise red flags unless verified. Baidu expects carefully worded descriptions to avoid misleading claims and hefty fines.

Platform accountability and brand protection for your business

Advertising in China comes with huge potential—but also clear responsibilities. With millions of ads served daily across platforms like Baidu, maintaining brand safety and respecting platform rules is critical.

Here’s what you need to know:

• Get proper consent: You must have permission before using someone else’s name, image, or brand in your ads. This includes celebrity endorsements and competitor brand mentions.
• Platform-level compliance: Major platforms like Baidu and WeChat are required to maintain ad archives and operate internal review systems. This helps track ads and enforce policy compliance.
• Baidu’s strict advertiser checks: Before launching campaigns, Baidu requires advertisers to verify their identity and submit valid business documents. This helps prevent fake or misleading ads.
• What to do if your brand is misused: If another advertiser uses your brand name, or logo, or misrepresents your business, you can report it directly to the platform. They have formal complaint systems to investigate and take action.

These steps might feel like extra effort, but they’re essential for building trust and creating a safe, reliable digital space. By following the rules, you protect not only your brand—but also your customers.
