How do I submit my site to Baidu?

Most guides on this topic are short, and many are out of date. Some still point to tools Baidu has retired.

This one sticks to what Baidu has written, with dates, and says where the evidence runs out. It’s part of our guide to Baidu SEO.

We read Baidu’s platform pages logged out, so we haven’t seen the account screens. Menu names below come from Baidu’s documents, and yours may differ.

What do you need before you submit?

You need a verified site, and in practice a real-name account. Baidu’s tool is open only to verified sites, so there’s no public form for an unknown URL.³

Requirement	Why it matters	Where to read more
Baidu account	Baidu’s help contradicts itself: one page says mainland numbers only 21, another allows foreign numbers through four products but not EU numbers 26	The phone number problem
Verified site	No verification, no tool 3	Setting up Webmaster Tools
Real-name account	Accounts without it can lose sitemap submission 4 and even the site’s verification 5	Setting up Webmaster Tools
Each hostname verified	Since 2021, unverified sites on the same main domain can’t be submitted 314	Verify every hostname you plan to submit
Reachable pages	Baiduspider must be able to fetch them 17	Why your site isn’t showing

Baidu tells users to complete real-name verification in the Baidu App.⁴ We couldn’t confirm that a foreign passport works there.

Which submission method should you use?

Use the manual form for a few key pages, and the API for anything regular. Treat the sitemap as a bonus if your account offers it. Baidu’s tool has these three methods.² The limits below come from its manual, last updated in August 2020, so your account may differ.

Method	Best for	Published limit	Needs a developer?
Manual	Homepage and a few key pages	None found	No
API push	New pages, on the day they go live 2	2,000 URLs per request, daily quota varies 2	Yes, or a plugin
Sitemap	Whole-site lists	50,000 URLs and 10 MB per file 2	Only to generate the file

Baidu calls the API its fastest method, and says sitemaps are indexed more slowly than API pushes.⁶ It also says original and time-sensitive content suits the API best.¹⁴

How to submit URLs by hand

This route needs no code, so it’s the natural first step for a small site.

1. Log in to the Search Resource Platform and select your verified site.
2. Open the tool. Go to 资源提交 (resource submission), then 普通收录 (normal indexing).¹⁵ Our English guide to the menus helps here.
3. Choose 手动提交 (manual submission).
4. Enter your URLs and submit them.

Start with your homepage and your main Chinese pages. Submitting pages one by one won’t scale, and Baidu’s manual gives no number for this method.²

How to submit URLs through the API

You send a plain-text POST with one URL per line, and Baidu answers with a count. Copy your call address from the API section of the tool, since it holds your site and your token.

1. Find your token. Baidu’s manual describes it as a 16-character string.² Treat it like a password.
2. List your URLs in a text file, one per line.
3. Send the file. Baidu’s manual shows this curl form:²

curl -H 'Content-Type:text/plain' --data-binary @urls.txt "http://data.zz.baidu.com/urls?site=www.example.com&token=YOUR_TOKEN"

4. Read the response, then log the result.

Field	Meaning 2
success	URLs accepted in this request
remain	URLs you can still push today
not_same_site	URLs ignored because they aren’t on this site
not_valid	URLs rejected as invalid

Watch remain above all, because it’s your real quota. A January 2021 Baidu article listed a shared quota of 100,000 URLs a day on its API row, without saying what shares it.¹⁵

That number is old, and Baidu adjusted API quotas in September 2023.⁴

An undated entry in a WordPress plugin changelog says quotas are “as low as 10/day for some sites”.¹⁶ A V2EX user reported 10 a day on a new site in March 2025, and said they had asked Baidu for more.⁹

Baidu’s manual says the daily limit depends on how many new, valuable links you send.² It also warns that resending old links can lower your quota, or cost you API access.²

Error (2020 manual)	Meaning 2	What to do
400 site error	Site not verified	Check the exact hostname in your account
400 empty content	POST body is empty	Check how the file is sent
400 only 2000 urls are allowed once	Too many URLs in one request	Split the list
400 over quota	Daily quota exceeded	Stop, and resume the next day
401 token is not valid	Wrong token	Copy it again from your account
404 not found	Wrong address	Copy the call address again
500 internal error, please try later	Occasional server fault	Retry

Can you still submit a sitemap?

We can’t confirm it, so check your own account. Baidu’s manual still describes sitemaps, but reports since 2023 point to a much narrower route, and one source says it has closed.

Date	Source	What it says
Oct 2015	Baidu	Sitemap access to open to all verified sites 11
Sept 2023	Baidu	Sitemap submission shut for low-quality sites and sites in accounts without real-name verification. Compliant sites to get rights and quotas back after the holiday 4
Mar 2025	V2EX users	Personal reports: sitemap can’t be submitted, one of them on a new site 9
June 2026	The Egg	Baidu ended direct XML sitemap submission in December 2025, with no source linked 8
Nov 2026	Baidu’s news page	No title mentions closing sitemaps 10

The Egg’s article also shows a caption reading “Zero quota available for XML sitemap submissions”.⁸ It speaks only of XML files, and doesn’t mention TXT. We found no Baidu announcement that matches its claim, in English or Chinese searches.

That absence proves little, because Baidu’s manual dates from 2020 and its tool log stops in 2021.²⁷ The evidence simply doesn’t settle it.

If your account does offer it, Baidu says the quota depends on your site’s quality.¹⁵ Follow the format rules in its 2020 manual:²

• Format: TXT or XML. TXT files are UTF-8 or GBK, with one full URL per line.
• Size: 50,000 URLs and 10 MB per file.
• Site total: fewer than 50,000 “sitemap links”, a term Baidu doesn’t define, or it stops processing and shows a warning.
• URL length: each <loc> is capped at 256 bytes.
• Characters: Baidu suggests avoiding Chinese in URLs, because of encoding problems.
• Scope: only URLs from the verified site the file belongs to. This 2021 rule is stricter than the manual’s line on main domains.²³
• ETag: Baidu strongly advises enabling it, and says it fetches ETag sitemaps more often.²¹¹

Index files are the classic trap. Baidu stopped supporting them on July 8, 2020,⁷ and a leftover one blocks new files until you delete it.¹⁴¹⁵

What about Fast Crawl?

You probably can’t use it yet. Fast Crawl (快速抓取) replaced Fast Indexing (快速收录), which Baidu took offline on April 26, 2024.¹²

Baidu grants it automatically to some high-quality sites, after its own evaluation, and it accepts only mobile and responsive pages.⁶

Baidu’s guide says such content is generally indexed within 48 hours.⁶ That describes a selected group, not your new site.

A V2EX poster said in March 2025 that fast crawl had no effect for them, and that you can’t submit quickly without the permission.⁹ That’s one person’s report, and we haven’t seen a test on a foreign site.

What older guides get wrong

Check the date before you follow any tutorial. These points are all out of date.

Older advice	Current position
Use the JavaScript auto-push snippet	Taken offline in December 2020, with no return date given 7
Submit through Fast Indexing	Retired on April 26, 2024 12
Sitemap index files are accepted 18	Not supported since July 8, 2020 7
Sitemaps are invitation-only 18	Opened to all verified sites in 2015, tied to account and quality since 2023 411
Baidu crawls within an hour of a sitemap 18	Baidu says processing generally starts within an hour, nothing more 2

What to do after you submit

Read the response, test the page, then measure. Baidu says the tool can speed up crawling but can’t settle whether content gets indexed.¹

1. Response or data feedback

   Accepted count

2. Crawl diagnosis

   What Baiduspider fetches

3. index volume

   Pages indexed

4. Content review if still absent

1. Check data feedback. It shows the links accepted that day, after removing duplicates.¹⁵
2. Run a crawl diagnosis. Baidu’s 2020 manual gives each site 70 tests a week, showing the first 200 KB the spider sees.¹⁷
3. Fix connection errors. Baidu points to slow servers, and to firewalls or DoS protection that block the spider.¹⁷ Check that you aren’t blocking real Baiduspider traffic.²⁷
4. Read index volume. Baidu treats it as the reference, not the site: operator.²³ Our guide to checking indexed pages explains how.
5. Review the content. If a page stays out, Baidu says to ask whether it’s high quality, useful and not a near duplicate.¹³

Be careful with recent figures. Baidu says index volume data from October 14 to 23, 2026 has no reference value, after a fault.²²

If your content sits in JavaScript, read whether Baidu reads JavaScript before you submit more URLs.

The bottom line

Verify the site, submit your key pages by hand, and use the API for new pages. Check your sitemap quota instead of assuming you have one, since the evidence conflicts.

Submission only introduces a URL. Whether the page gets indexed depends on what Baidu finds when it arrives.
