Baidu Index

Baidu Index — China's Most Authoritative Internet Big Data Analytics Platform

Baidu Index (百度指数) is a data sharing and analysis platform launched by Baidu, built on massive user behavior data. Since its launch in 2006, powered by over 6 billion daily search queries, it has become one of China's most authoritative statistical analysis tools, widely used in marketing decisions, market research, and public opinion monitoring.

Core Feature Modules

• Search Index (Trend Research): Based on user search volume data, it computes a weighted frequency score for keywords across Baidu web searches, covering overall, PC, and mobile trends. Historical data is available from June 2006 to present, with support for comparing up to 5 keywords side-by-side or aggregating synonymous keywords.
• News Index: Based on Baidu's smart content distribution data, it measures user engagement (reads, comments, shares, likes) with news content. Together with the Search Index, it forms a dual-dimension view of both active searching and passive content consumption.
• Demand Mapping: Powered by semantic mining technology, it visualizes the hidden interests and purchase intent behind keywords, showing what related terms users also search for — helping brands understand consumer mindsets and inform marketing strategy.
• Audience Portrait: Leverages big data clustering analysis on Baidu user search data to produce demographic breakdowns of keyword searchers: age distribution, gender ratio, geographic spread, and interest categories — a low-cost, data-driven alternative to traditional market research surveys.
• Public Opinion Monitor: Tracks media coverage and sentiment trends related to keywords in real time, monitoring news volume and public discourse to help brands respond swiftly to emerging PR situations.
• Industry Analysis: Provides macro-level trend overviews, regional distribution, audience attributes, and search time patterns by industry, serving as a strategic reference for industry researchers and business planners.

Practical Features

Users can bookmark up to 50 keywords for ongoing monitoring of brand terms and competitors. A paid keyword subscription service allows uncollected terms to be tracked for up to one year. Both a desktop web interface and a mobile WeChat mini-program version are available for on-the-go access.

Use Cases

Baidu Index is widely used by digital marketers, SEO specialists, brand managers, market researchers, academics, and content creators as an indispensable free big data tool for understanding Chinese internet user behavior and market trends.
