Microsoft Edge Under Scrutiny for Blocking Baidu Search Results

In a development that has caught the attention of internet users and tech communities alike, Microsoft’s Edge browser has been reported to flag search results from Baidu, a leading Chinese search engine, as “unsafe.”

Users navigating Baidu’s search results through Edge are confronted with a warning stating, “This website has been reported as unsafe,” necessitating additional steps to proceed to the desired web page.

This issue, first highlighted by user feedback on January 29, persists with Edge displaying “red” warnings for all Baidu-related links, effectively casting doubts on the safety of visiting such sites.

Despite attempts to address this matter, the problem remains unresolved, raising questions about the implications for Baidu’s accessibility among Edge users.

Upon further investigation, some tech professionals have speculated that the root cause of these warnings might be linked to an issue with the Microsoft Defender Smartscreen library. #This feature, designed to safeguard users from phishing attacks and malicious websites, might be erroneously flagging Baidu’s search results as dangerous.

For users looking to bypass this barrier, a temporary solution has been suggested: disabling the Microsoft Defender Smartscreen feature within the Edge browser’s settings under Privacy, Search, and Services-Security.

This adjustment allows users to access Baidu links without encountering the stark “unsafe site” warnings.

This incident sparks a broader conversation about the mechanisms and criteria used by browser security features to evaluate and label websites as hazardous. It also highlights the delicate balance between protecting users from genuine online threats and ensuring that such protective measures do not inadvertently hinder access to legitimate information sources.

As of now, Microsoft has yet to comment on the situation or provide an official solution. The tech community and users alike await a response that could clarify the reasons behind these warnings and, hopefully, offer a resolution that safeguards user security without compromising access to global search resources like Baidu.

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.
