Baidu's extensive data collection practices, including user location, search terms, and website visits, have raised significant privacy and security concerns.

Who are baidu and what is their primary business model?

Baidu Inc. is a Chinese multinational technology company specializing in internet-related services and products, as well as artificial intelligence (AI). Founded in 2000, Baidu operates the largest search engine in China and provides a variety of web services to users globally

Their business model primarily revolves around online marketing services, especially pay-for-performance marketing, wherein advertisers pay Baidu to display their ads prominently in search results. This model allows businesses to reach users actively searching for relevant information, significantly boosting their chances of conversion. Baidu offers an array of products, including but not limited to Baidu Search, Baidu Ads, and Baidu Union

Baidu Search is the most popular search engine in China, handling over 76% of the country's search queries. Baidu Ads provides a platform for pay-for-performance advertising, enabling businesses to target users based on their search behaviors. Baidu Union extends this advertising network by allowing advertisers to post video ads on affiliated websites

Other noteworthy products include Baidu Wallet, Baidu CarLife, Baidu Health, Baidu Brain, and the Apollo Project, each serving different consumer needs but unified under Baidu's core AI technology.

What are the specific types of data that baidu collects from its users?

Baidu collects a variety of data from its users. This data can be grouped into several categories including personally identifiable information, device data, contact data, and third-party application data. For instance, Baidu collects location data, search terms, and website visits which are sensitive pieces of information

The company also gathers device-specific data like device IDs and other hardware information. Contact data, which might include information from a user's contact list, is also collected. Third-party application data forms another significant chunk of the data Baidu accrues, often without robust encryption, highlighting vulnerabilities in user data privacy

The data collection is extensive, covering activities from thousands of apps running Baidu code. Baidu may also share some of this collected data with third-party companies, adding another layer of complexity to data privacy concerns.

What is the market share of Baidu's search engine in China and globally?

As of recent market statistics, Baidu commands a substantial share of the search engine market, particularly in China. Within the Chinese market, Baidu controls approximately 76.05% of the market share, making it the dominant search engine in the country. Globally, Baidu has a smaller footprint, accounting for about 0.74% of all worldwide search engine queries

This massive market share in China highlights Baidu's pivotal role in shaping the internet ecosystem in one of the world's largest consumer markets. Despite its low global market share, Baidu's impact domestically cannot be overstated, given the size of the Chinese internet population and the depth of services provided by the company.

What are the purposes for which Baidu collects and uses user location data?

Baidu utilizes user location data for several purposes. These include but are not limited to building an employment index for China, predicting Apple's revenue in the Chinese market, and monitoring overall employment and consumer behavior. By tracking the flux of people around offices and shops, Baidu can infer employment and consumption activities, offering valuable insights into economic trends

Baidu also employs this data to improve its services, such as providing personalized search results and local recommendations. Additionally, location data is used in advertising to target users more effectively based on their geographical location and interests. Baidu Maps, another of Baidu's services, leverages location data to offer maps and navigation services

Location data also finds use in research and development, helping Baidu to analyze user behavior and preferences. However, the collection methods and uses of this location data have raised significant privacy concerns among users and regulatory bodies.
