In short. Baidu combines search, a personalized feed, publisher content and knowledge communities, with separate tools for website submission and crawl checks.
Definition: Baidu's Chinese search ecosystem connects its search service with Baidu App, a publisher network, and knowledge and community products. It brings together content from external websites and apps with material published within Baidu's services.
This description follows Baidu's 2025 Annual Report, published on 17 March 2026, which identifies Chinese-language internet search as one of its markets.
Key facts
- Baidu's annual report describes Baidu App as providing search and a personalized content feed, and aggregating content and services from third-party apps and websites.
- As of October 2026, the Search Resource Platform lists website submission tools, index counts, traffic and keyword data, and crawl diagnostics.
- Baidu's crawler help page, available in October 2026, places the robots.txt crawl-control file at the website root and documents a rule targeting Baiduspider.
How do search and the feed work together?
In the annual report's Mobile Ecosystem description, Baidu App provides access to search, a feed, content and other services on mobile devices. A feed is a personalized timeline: Baidu describes its selection as based on users' demographics and interests. Search and the feed therefore provide different routes to content inside the same app.
The report also describes search input through text, voice, images and video. It reports AI-generated content on roughly 70% of mobile search result pages by October 2025. That figure concerns the presence of AI content on result pages; the report describes it as a measure of Baidu's search transformation.
Baidu's knowledge products include Baidu Wiki, an encyclopedia compiled with experts, and Baidu Knows, a community where users ask questions of individuals, professionals and enterprises. Baidu Post organizes discussions into topical communities and integrates with search.
How does publisher content enter the ecosystem?
Baidu's partner-services description defines Baijiahao, also called BJH Accounts, as its publisher network. It aggregates articles, photos and video from media outlets and other professional sources for distribution through search, the feed and short-video products. The report states that BJH accounts let content providers place material on the network and make it searchable.
Baidu Union is a partner network that extends distribution onto third-party websites and mobile apps. Some partners embed Baidu Search or a search function powered by it. Partners can also use Baidu's recommendation system to provide feed content and advertisements. For a business assessing a placement, the relevant context can therefore be a Baidu service, a publisher account or a partner property.
What can a website owner check?
The Search Resource Platform separates website resource submission from data reporting. Its menu includes ordinary inclusion submission (普通收录), dead-link submission (死链提交), index counts (索引量), and crawl diagnostics (抓取诊断).
Baidu's crawler help documents robots.txt as a file controlling crawler access. For a deliberate restriction on crawling the entire website, its Baiduspider example is:
User-agent: Baiduspider
Disallow: /
The same help page explains that a blocked page can still appear in search when other websites link to it, with descriptions supplied by those other sites.
