Baidu’s verification process for ads is known for its complexity, even when you speak fluent Chinese and have a Chinese business license in hand.
If your website was rejected on the first application, you are not alone. In 2026, we see more rejections than five years ago, not fewer. Baidu has tightened almost every layer of the review: business license matching, ICP filing, content compliance, and now AI-generated content detection.
As a Baidu Agency, we handle this every month for clients. Most rejections are fixable in one to two review cycles once you know exactly what tripped the filter.
Olivier Verot is the founder and CEO of GMA, based in Shanghai since 2012. His team has resubmitted and unblocked dozens of Baidu ads accounts for foreign brands over the past decade.
Main Reasons for Rejection
- Non-compliance with account requirements. Baidu has strict criteria for ads. Invalid traffic, policy breaches, or a landing page that does not match the ad copy can all trigger a rejection.
- Legitimacy and license verification. Businesses must prove they are who they say they are. A business license, an ICP filing, and the website itself all need to point to the same legal entity. Any mismatch leads to denial, and this is by far the most common reason we see in 2026.
- Content flagged as AI-generated and unlabeled. This is new. Chinese platforms now require visible labeling when a page uses AI-generated text or images. Unlabeled AI content gets throttled or pulled, and in serious cases the account faces a fine.
What Changed in 2026
The rulebook did not change overnight, but enforcement did. Four shifts matter if you are applying today.
ICP filing is checked, not just requested
Baidu only accepts mainland Chinese business licenses for ad accounts. The website used in the campaign must be owned by that same Chinese legal entity, and the ICP filing must sit under that exact company name. Foreign companies cannot file ICP directly. You need a WFOE, a joint venture, or a local hosting sponsor. If the names on the business license, the ICP filing, and the domain registration do not line up character for character, the application is rejected before a human even looks at your ad copy.
Getting an ICP license generally takes around two months once the paperwork is filed correctly, and registered capital requirements apply for commercial sites, as detailed in this ICP license guide for foreign companies. Plan for this timeline before you commit to a launch date.
Content compliance is stricter, especially for health claims
Medical, pharmaceutical, and health-adjacent advertising went through a real crackdown in 2026. Regulators across several agencies are now reviewing existing promotional material, not just new submissions. If you advertise anything touching health, beauty treatments, supplements, or medical devices, you need the matching medical institution license and an advertising review approval number, and the number has to match the actual content of the ad. A skincare brand that hints at “treating” a skin condition, rather than describing a cosmetic effect, will get flagged.
We cover the document list for this category in our guide to medical and health care marketing in China.
Review timelines, realistically
Automated review usually clears in thirty minutes to two hours. Human review is where accounts wait: one to three business days for most campaigns, longer for anything with images, video, or a regulated category, and longer still during policy update periods when the review queue backs up. Submit on a weekday morning if you want to enter the same-day queue.
Business license scope now gets cross-checked against content
A newer trigger we see often: the business license lists one activity, the website talks about another. A company registered for appliance repair that publishes content resembling medical advice is a textbook rejection case, according to Baidu’s own policy center. Keep your site’s content inside the scope printed on your license, or update the license before you advertise outside it.
Understanding Baidu Ads Requirements
Baidu Ads is the dominant paid search platform in China, roughly what Google Ads is in the US. To advertise, a business must:
- Hold a valid mainland Chinese business license, matching the ICP filing and the domain owner.
- Comply with Baidu’s category rules, especially for healthcare, finance, and education.
- Avoid content related to drugs, explicit material, gambling, or unverified financial promises.
- Label any AI-generated text or image used on the landing page.
A Baidu PPC account under review. Most rejections trace back to a mismatch between the business license, the ICP filing, and the landing page content.
Solutions for Rejected Accounts
Whitelisting
Whitelisting still exists in 2026: only approved domains can run ads under the account. It is a workaround, not a fix, and Baidu can still pull a domain from the whitelist if the content changes later.
Fixing compliance, step by step
Getting your account to meet Baidu’s rules is worth doing properly the first time. Rejections cost weeks, not days, once you factor in resubmission queues.
- Check the current guidelines. Baidu updates its policy center regularly. What passed review last year may not pass today.
- Keep ads truthful and specific. The ad has to match what the landing page actually delivers. Vague promises or anxiety-driven copy (“if you don’t act now…”) are flagged more often than plain, factual claims.
- Clean up the landing page. Every page an ad points to must follow the same rules as the ad itself, including AI-content labeling and license scope.
- Match your license to your content. If your business expands into a new category, update the license before the content goes live, not after.
- Mark the ad clearly. Any page with a shopping link, a checkout button, or a paid placement needs a visible “ad” label.
Getting a refunded deposit
If the account ultimately cannot pass review, you may be entitled to a refund of your opening deposit. Claim it promptly. Baidu does not chase you to remind you.
Case Study: How a Rejected Account Got Approved
Sophie runs a French pet nutrition brand selling premium dog food through a Tmall store and a Chinese-language site. She applied for a Baidu ads account directly under her French holding company, using a Chinese agency’s shared hosting for the website. Rejected, twice, with no clear explanation beyond a generic compliance notice.
The actual problem: the ICP filing sat under the hosting agency’s name, not hers, and her business license was French, not Chinese. Baidu had no way to confirm the website belonged to a mainland entity it could hold accountable.
The fix took five weeks. Her WFOE in Shanghai filed the ICP registration under its own name, the website moved to servers tied to that filing, and the Baidu account was reopened under the WFOE’s business license, matching top to bottom. The landing pages were also rewritten to drop unverified nutrition claims that read like medical benefits.
Second submission, approved in three business days. The account generated 340 qualified leads in its first month live, at a cost per lead about 30% below her earlier Xiaohongshu campaigns, because the traffic was already searching for the product category instead of discovering it cold.
DeepSeek and AI Search: What “SEM-Ready” Means Now
Baidu has folded DeepSeek into its main search experience, reaching hundreds of millions of users with an AI summary layer sitting above the classic results. This matters for your ads strategy, not just your organic content.
AI search retrieves and ranks structured, verifiable information first. Pages built to game keyword density, or stuffed with generic self-promotion, get ignored by the summary layer and increasingly by human reviewers too, since both are now trained to spot the same shallow patterns. A landing page that clearly explains what the product does, who it is for, and how to compare it to alternatives performs better in review and in AI-generated summaries. China’s market for this kind of AI-search optimization grew sharply in 2026, which tells you advertisers are already adjusting. If your landing pages still read like a 2019 product brochure, that is worth fixing before your next Baidu submission, not after. We wrote a longer breakdown in our piece on why your website may be invisible to DeepSeek.

FAQ
How long does Baidu ads review take in 2026?
Automated checks clear in thirty minutes to two hours. Human review typically takes one to three business days for standard campaigns, longer for regulated categories like health or finance, and longer during periods when Baidu updates its policies and the review queue backs up. Submit on a weekday morning for the best chance of same-day processing.
Can I get a Baidu ads account without an ICP-filed website?
No. Baidu requires the advertised website to carry an ICP filing under the same mainland Chinese business license that opens the ad account. Foreign companies need a Chinese entity, a WFOE or joint venture in most cases, to file ICP directly. Budget around two months for the filing itself, on top of the account application.
What triggers a rejection for AI-generated content?
Unlabeled AI-generated text or images on your landing page. Chinese platforms now require a visible label when AI tools produced the content. Missing the label can get the page throttled or removed, and repeated violations can bring a fine. If part of your site was written or designed with AI tools, label it before you submit for review.
Do health and beauty brands need special approval?
Yes. Any content touching medical claims, supplements, or beauty treatments needs a matching institution license and an advertising review approval number tied to the specific claim you are making. Regulators tightened enforcement on this category through 2026, including audits of material already live. Cosmetic effect language passes more easily than anything implying a medical or therapeutic result.
Is whitelisting still a valid workaround in 2026?
It exists, but treat it as temporary. Whitelisting lets an approved domain run ads without a fresh account review, but Baidu can still remove a domain from the whitelist if its content changes or a complaint is filed. It buys time. It does not replace fixing the underlying license and ICP mismatch.
Key Takeaways
- Baidu checks that your business license, ICP filing, and website all belong to the same Chinese legal entity, this is the single biggest cause of rejection in 2026.
- AI-generated content must be labeled, or it risks being throttled, removed, or fined.
- Health and beauty claims face tighter scrutiny than in past years, with active audits of live content.
- Review usually takes one to three business days once the account is properly filed.
- A rejected account is rarely a dead end. Most cases we see are fixed in one or two resubmission cycles once the actual mismatch is identified.
