Recorded markets
The research records China as the main market for Baidu.
Does Baidu use structured data?
The research records documented support for JSON-LD for Baidu. It records 10 rich result types, listed in the next section.
| Format | Documented support | What the research records |
|---|---|---|
| JSON-LD | Yes | Documented in two places only. (1) Time factors: keys pubDate, upDate, lrDate; the spec states "PC和移动端页面仅支持JSON-LD格式提交时间因子。" (2) Official-account (百度官方号) pages using the cambrian context[14]. Both use Baidu's own keys and no schema.org type is named.[11] |
| Microdata | Not documented | Not mentioned on any Baidu page fetched[1-32]. The 2014 results-display course says structured display is fed by a submission tool and an annotation tool, and names no markup syntax.[10] |
| RDFa | Not documented | Not mentioned on any Baidu page fetched[1-32].[10] |
| Open Graph | Not documented | Not mentioned on any Baidu page fetched[1-32].[10] |
| Microformats | Not documented | Not mentioned on any Baidu page fetched[1-32].[10] |
| Twitter Cards | Not documented | Not mentioned on any Baidu page fetched[1-32].[10] |
“Not documented” means the pages read do not say; it does not mean the format is ignored.
Other formats and channels
meta applicable-deviceDocumented
Meta name applicable-device with content pc, mobile or pc,mobile declares which device a page serves. Code-adapted sites pair it with the Vary: User-Agent header[26].[25]

sitemap XML with data/display payloadDocumented
Legacy 结构化数据工具 (docs 2013 to 2015): sitemap-style XML in which each url carries a data > display block; four content types. The hosted site search feed[23] uses the same skeleton with other fields. Current availability unknown.[19]

What does Baidu ask of site owners?
Its own vocabularies, tags and feeds
cambrian.jsonld (百度官方号 JSON-LD context)
Context file that maps title to schema.org/headline, description to schema.org/description, images to a list of schema.org/image and pubDate to schema.org/DateTime. It does not define upDate, lrDate or isOriginal. The help doc[14] cites it on the zhanzhang.baidu.com host; the copy fetched here is served from ziyuan.baidu.com.[15]
时间因子 keys: pubDate, upDate, lrDate
Three Baidu-defined JSON keys for publish time, update time and latest reply time. Spelling varies inside the spec: pubDate in the example, pubdate in running text, Pubdate in the table.[11]
结构化数据 XML (urlset / url / loc / data / display)
Sitemap-style XML where each url carries a data > display block of typed fields, used by the structured data tool for Q&A, software, online document and file download pages. Many field names look like schema.org property names (aggregateRating, datePublished, operatingSystem, inLanguage) but no page cites schema.org.[19]
站内搜索 data feed
XML feed for Baidu's hosted site search product (not web results). Same urlset / url / loc / data / display skeleton, 50,000 URLs and under 10 MB per file, with extended fields such as pubTime, breadCrumb and thumbnail, and movie fields actor, director and aggregateRating.[23]
互联网论坛收录开放协议 (forum inclusion open protocol)
XML protocol that lets forum sites describe their boards and threads for inclusion. The tag list is published only as images.[29]
百度数据开放平台 (框计算)
Partner program that takes structured data from sites and shows it directly in results. Its help page names no format.[28]
Sitemap mobile:mobile tag
Sitemap extension tag that marks a URL as mobile (no type or type=mobile), adaptive (type=pc,mobile) or code-adapted (type=htmladapt). A URL with no tag is treated as a PC page.[25]
applicable-device meta tag
Declares the device a page serves: pc, mobile or pc,mobile.[26]
mobile-agent meta tag
Points a PC page to its mobile version, with a format value of wml, xhtml or html5.[31]
What could not be verified?
These claims about Baidu came up in the research, but no page that could be read confirms them. They are kept apart, and nothing above rests on them.
The JSON-LD wrapper for time factors (script tag, @context, @id) and whether it reuses the cambrian context.
Why it is open: Example code is published as images; image downloads are outside the scope of this research.
How it was checked
Fetched https://ziyuan.baidu.com/college/articleinfo?id=2210 twice; the text carries only the three key lines. The full example sits in two images (https://zhanzhang.bj.bcebos.com/files/061781528444301.PNG and https://zhanzhang.bj.bcebos.com/files/031111666865503.png), not fetched.
Baidu's 结构化数据工具 and its four XML types are still accepted today.
Why it is open: The tool sits behind login and no public page states its current status.
How it was checked
https://ziyuan.baidu.com/schema/index returned 301 to http://ziyuan.baidu.com/. https://ziyuan.baidu.com/ returned 302 to a cas.baidu.com login check (not followed). The 2020 tool manual[1] lists 17 chapters and none covers structured data.
Formats and current status of 百度数据开放平台 (open.baidu.com).
Why it is open: Platform page failed to load.
How it was checked
https://open.baidu.com/data/ returned HTTP 500 Internal Server Error. The help page[28] names no format.
Baidu reads Microdata, RDFa, Open Graph or schema.org types for result display.
Why it is open: Not documented on any page fetched. Absence of documentation is not proof of non-support.
Tag list of the 互联网论坛收录开放协议.
Why it is open: Images not fetched.
A public structured data validator or testing tool exists for Baidu.
Why it is open: No public validator page found.
The 百度官方号 cambrian JSON-LD is still processed.
Why it is open: The doc does not state the product's current status.
The Baiduspider token list is complete and current.
Why it is open: The canonical spider page redirects away and the FAQ carries no date.
How the video fields in 百度搜索视频规范 are submitted.
Why it is open: The spec names no submission format.
How it was checked
Fetched source 24; it has a field table only.
