Baidu search referrer
Baidu is the dominant search engine in mainland China, so a baidu.com referrer typically signals organic search from a Chinese-language audience. As with Google, the referrer identifies the source but not the query; Baidu's own webmaster platform is where query-level data lives. The China context also shapes which other engines you may see.
Baidu and the China search market
Baidu holds a leading share of search in mainland China, where Google is not generally available. A baidu.com referrer therefore usually reflects a Chinese-language audience reaching you through Baidu's organic results.
If you see meaningful Baidu traffic, treat it as a distinct market signal — the audience, language, and indexing behaviour differ from Western search engines, so do not merge it into a single 'search' line.
- Baidu leads search in mainland China
- Audience is typically Chinese-language
- Distinct indexing and ranking from Google
Where Baidu query data lives
Like Google, Baidu does not pass the search query to your site, so the referrer alone cannot tell you the keyword. Baidu operates its own webmaster platform (Baidu Ziyuan / webmaster tools) where verified sites can see indexing and performance data. Treat that, not the analytics referrer, as the query source.
How it appears in analytics and logs
A baidu.com referrer on an organic visit indicates Baidu search, usually a Chinese-language audience in mainland China. The query is not in the referrer; Baidu's webmaster platform reports site performance.
Diagnostic use case
Interpret a baidu.com referrer as organic search from a China-based audience and look to Baidu's webmaster tools for query data.
What WebmasterID can help detect
WebmasterID normalises baidu.com as an organic search source when present, and treats China-market engines as their own sources rather than folding them into a generic search bucket.
Common mistakes
- Folding Baidu into a generic search bucket and losing the China signal.
- Expecting search keywords in the baidu.com referrer.
- Inferring precise visitor location from a Baidu referrer.
Privacy and accuracy notes
The referrer identifies the source without exposing the user's search terms. WebmasterID reads the referrer when present and does not attempt to recover hidden queries or infer precise location.

- Yandex search referrer
Yandex is a leading search engine in Russia and is used across several neighbouring regions. A yandex referrer — on yandex.ru, yandex.com, or another regional domain — typically signals organic search from that audience. The query is not in the referrer; Yandex Webmaster is the source for query-level data.
- Naver search referrer
Naver is the dominant search portal in South Korea, and a naver.com referrer typically signals a Korean-language audience. Naver is more than a search engine — its blog, cafe, and curated content ecosystem drives much of its referral traffic, so attribution differs from a pure search engine. Naver's own webmaster tools report query and indexing data.
