Does Baidu index foreign websites?

If your site is hosted in Europe or the US, you’ve probably read both that Baidu ignores foreign sites and that it treats them like any other. Neither claim holds up well.

Baidu can index foreign sites. It rarely explains what happens when it doesn’t. This page separates what Baidu wrote from what agencies assert, as part of our guide to Baidu SEO.

What has Baidu actually said about foreign sites?

Very little, and most of it dates from 2017. We searched Baidu’s webmaster site and found no rule excluding foreign sites, and no recent text on them.

Baidu text	What it says	What it leaves out
Notice, October 12, 2017 1	Chinese-language sites on overseas servers will have display problems in search	The cause, how widely it applies and any fix
Server tips, October 12, 2017 2	“中文网站不建议选择国外服务器”: overseas servers aren’t recommended for Chinese-language sites	Any reason, or what “overseas” covers
Ranking principles, December 18, 2020 3	Barred from search: content that breaks its rules, low-quality content, content costly to access	Any mention of hosting location
Sitemap quota notice, May 14, 2021 5	Sites without an ICP limited to one sitemap file a day	Whether that limit still applies
Baiduspider FAQ, undated 4	Crawl rate depends on server capability, site quality and update frequency	Any mention of location

Two details matter here. The 2017 notice is titled as being about indexing, but its text only mentions display. So it doesn’t say these sites leave the index.

The 2021 quota is useful evidence too. A limit on sites without an ICP means those sites could use Baidu’s submission tool at that date.⁵

Do foreign sites really appear on Baidu?

Yes, though the public proof is patchy. There’s a large correlation study, plus individual accounts from site owners. We found no study that measures foreign sites as a group.

What the data shows

Marcus Pentzek’s 2023 correlation study covered the top 20 results for 10,000 Chinese keywords.⁶ He concludes that “any website accessible in China can rank”. He’s a director at Jademond, a China marketing agency,²¹ so read that as a practitioner’s view.

Measure, 2023 study 6	Result
Top-ranking pages with an ICP reference, seen in the footer	48%
.com domains among top results, without Baidu subdomains	72.59%
Share of content in Chinese characters on top pages	About 85%

These figures need care. A .com domain doesn’t make a site foreign, since many Chinese companies use one. And a missing ICP reference doesn’t prove a site has no ICP.

So the study weakens the idea that only mainland sites can rank, without counting foreign sites. Our guide to ranking on Baidu without an ICP goes further.

What one foreign site went through

The most detailed public record we found comes from Silas S. Brown. His site sat on University of Cambridge servers until 2019.⁷ It’s one personal site, so read it as a case, not a norm.

1. 2017English page visible in English results on mobile.
2. February 2018Chinese pages still absent.
3. July 2018Listed, matched on title alone.
4. December 28, 2018Matched on text.
5. June 2019Removed after a 404 error, relisted in four days.

When	What he recorded 7
From mid-2017	An English test page was missing on desktop, then topped a separate “English results” page on mobile
By February 2018	A Chinese sitemap, a November 2017 Baidu Knows post and December 2017 URL pings had brought no Chinese listing
July 2018	The homepage appeared, but his tests matched on its title only
December 28, 2018	The homepage matched on a phrase from its body text
June 2019	A 404 outage got it delisted by the 24th, relisted by the 28th
2020 to 2022	Listings kept coming and going, and he reports Chinese pages delisted from 2022

His record shows that indexing isn’t a yes or no state. A page can be listed, match on its title alone, and later disappear.

Why crawled doesn’t mean indexed

A team running a Discourse forum reported this in 2019. According to the thread, the site was in Chinese on a .cn domain, hosted in Hong Kong.⁸

Their logs showed dozens of daily Baidu requests to topic pages, all returning 200. Yet a site: search showed 5 links, none of them topics.⁸ The thread never confirmed a cause.

What can keep a foreign site out?

Nothing we read ties non-indexing to one proven cause. Here’s what each obstacle rests on, since the strength of the evidence varies a lot.

Obstacle	Evidence	Strength
Your server or robots.txt blocks the crawler	Baidu says host settings that block crawlers cause harm, and that it follows robots.txt 24	Baidu text
Frequent downtime	Baidu calls it “致命伤害”, fatal damage for crawlers 2	Baidu text
Content only in JavaScript	Baidu asks for text, not JavaScript, for important content and links 20	Baidu text, 2019
Few links pointing to you	Baidu calls links the main route to finding pages 9	Baidu text, 2017
Overseas server	Notice of display problems, no explanation 1	Baidu text, old and vague
Slower crawling of slow foreign sites	Marketing to China states it, without a source 10. Baidu ties crawl rate to server capability, and doesn’t mention location 4	Agency claim
Slow loading from abroad	Pentzek says it “could impact rankings” 6. SEO Sherpa says Baidu “tends to favor” mainland servers, yet foreign sites can rank if “accessible and fast” 23	Agency views, no figures
English-only content	Agencies disagree, and Baidu is silent	Unsettled

Some of these aren’t really foreign problems. A strict bot filter or a JavaScript-only build would hurt any site, wherever it’s hosted.

Links are worth checking as well. Brown thought one mention on a scraped copy of a Weibo forum had been enough to get a Chinese page indexed, which is one owner’s inference.⁷ See our guide to backlinks for Baidu.

What your setup means for indexing

Your setup changes which evidence applies to you. Hosting and language are the two variables that matter here.

Your setup	What Baidu has written	Public evidence	Read next
English site, hosted abroad	Nothing we could find	One personal site, plus our own live searches	English sites
Chinese site, hosted in Europe or the US	Directly covered by the 2017 notice 1	Brown’s case 7	Why you’re not showing
Chinese site, hosted in Hong Kong	Unclear: “国外” isn’t defined 12	The 2019 Discourse case 8	Hong Kong hosting
Chinese site, hosted on the mainland	Outside the notice	Not a foreign setup: it needs an ICP filing, plus a license if commercial 22	ICP license

The Hong Kong row is the honest gap. Marketing to China calls it a “middle ground”,¹⁰ but Baidu’s text doesn’t say whether Hong Kong counts as overseas.

How to check your own site

Your logs and a few searches will tell you more than any general rule. This works without a Baidu account until the last step.

1. Search site:yourdomain.com on baidu.com. Baidu calls this figure a rough estimate, so use it only to see whether any pages show.¹²
2. Search a page’s exact title. Then search a sentence from its body text. Brown’s site passed the first test months before the second.⁷
3. Look for Baiduspider in your server logs. Check which pages it requests, and which status codes it gets.
4. Confirm it’s really Baidu. Run a reverse DNS lookup on the IP address. Genuine hostnames end in .baidu.com or .baidu.jp.⁴
5. Read your robots.txt and firewall rules. Allow about 48 hours for a robots.txt change to take effect.⁴
6. Use the index volume tool if you have an account. Baidu says it’s the reference, updated daily to weekly.¹² Ignore its data for October 14 to 23, 2026, which Baidu says has no reference value.¹³

Then take what you found to why your site isn’t showing on Baidu, which matches each result to the stage that failed.

The bottom line

Baidu can index a foreign website, and nothing we found says it refuses to. But the only direct statements we found from Baidu discourage overseas servers for Chinese sites, and they date from 2017.

So don’t ask whether Baidu accepts foreign sites. Find out where yours stops: crawled, indexed or ranked.

How Index in China can help

We translate your site into Simplified Chinese with a human reviewer, handle its submission to Chinese search engines where the account allows it, and send a monthly report on Chinese traffic.

We commit to a set number of indexed pages and to reporting, not to traffic. We’ll tell you when your case needs a local adviser. See what we do.
