Baidu Removes 15.08 Billion Pieces of Harmful Content

In a significant stride toward a safer digital world, Baidu has recently unveiled its comprehensive information security management data for Q4 2023, marking a pivotal moment in the fight against online harm.

Over 15.08 billion pieces of harmful content spanning categories such as pornography and gambling were eradicated from Baidu’s platforms, underscoring the tech giant’s unwavering commitment to creating a secure and wholesome online environment.

The Baidu Content Security Center, employing a blend of cutting-edge artificial intelligence technologies and meticulous manual inspection, spearheaded this monumental cleanup operation.

The AI-driven approach successfully identified and eliminated over 15.06 billion instances of harmful content, while the manual inspections contributed to the removal of an additional 22.583 million items, focusing on pornography and copyright infringement among others.

This quarter also saw the execution of specialized campaigns against pornography, resulting in the clearance of 73,843 sets of harmful pornographic keywords, 13,241 guide word sets, and the closure of 1,122,156 accounts and 3,532 post bars. More than 7.39 billion harmful links were also purged in the process, further sanitizing the digital space.

Across Baidu’s varied platforms, the purge was extensive: Baidu Search eradicated over 14.6 billion harmful pieces; Baidu Tieba intercepted 103 million; Baidu Netdisk removed over 34.29 million pornographic and illegal files; and Baijihao cleaned up 740,000 pieces of remaining harmful content.

Furthermore, through the Internet User Rights Protection Plan, Baidu addressed 17,748 complaints from netizens, resulting in refunds or payments totaling more than 9.331 million yuan.

This initiative not only underscores Baidu’s dedication to maintaining a clean digital ecosystem but also highlights its commitment to protecting user rights and fostering trust within its community.

This colossal effort by Baidu represents a critical step forward in the battle against online harm, setting a new standard for digital cleanliness and security.

By leveraging advanced AI technology alongside rigorous manual inspection, Baidu is at the forefront of creating a safer and more secure internet for all.

He has worked in search for more than a decade, in-house and agency-side, and is regarded as one of the West’s leading voices on search engines beyond Google, including Yandex, Baidu, Naver and Cốc Cốc. On ReadIsi, Dan covers the engines and AI answer platforms that English-language coverage tends to miss: Baidu and ERNIE, Yandex and Alice AI, Naver, Cốc Cốc, Shenma, Sogou, WeChat and Weibo search, plus DeepSeek and Alibaba’s Qwen. He also keeps dated records of documented changes, such as the Yandex, Baidu and Naver algorithm update histories and the DeepSeek, ERNIE and Qwen model update histories. His approach is to take learnings from global search engines and apply logic with a high evidence threshold. A claim needs a source, patterns seen in one market are treated as a hypothesis until they are checked in another, and where the evidence is thin he says so. For brands, that means advice built on what can be shown, with measurement that separates being cited from being chosen. Dan is credited with coining the term “edge SEO” and won the inaugural TechSEO Boost research competition in 2018 for his work on CDN and edge changes for SEO. In 2026 he was credited with coining “Infinite Tail” to describe how keyword research is changing with AI search. He is the author of AI Search Marketing For The Travel Sector, writes for Search Engine Journal, Search Engine Land and Travel Marketing Guy, and has advised technology, SaaS, travel and enterprise ecommerce brands, including Cloudflare, GitLab and Airbnb. He has given multiple talks and panels at the International Search Summit in Barcelona, and has also spoken at Optimization Moscow, brightonSEO, Google Search Central Live Deep Dive Asia in Bangkok, Athens SEO and the Asia SEO Virtual Summit 2026, where his talk looked at how Baidu, Naver, DeepSeek, Tencent, Cốc Cốc and Yandex built their own AI answers.
