Qihoo 360 Search, commonly known as 360 Search or so.com, is one of China’s alternative search engines. It is not a replacement for Baidu, but it can matter in selected search strategies, especially where desktop users, security software ecosystems, B2B research or lower-cost testing are relevant.
This updated Tenba Group guide explains how 360 Search fits into China search marketing in 2026, when to consider it and how to test it without distracting from the larger China search ecosystem.
What is Qihoo 360 Search?
360 Search is operated by Qihoo 360, a company known for internet security products, browsers and related services. The search engine is available through so.com and has historically benefited from 360’s browser and security-software ecosystem.
In China search planning, 360 Search usually sits behind Baidu in priority. However, smaller does not mean useless. A niche search engine can still produce valuable leads if the audience, keyword set and cost environment fit the business.
Why marketers should know it
Baidu remains the core classic search platform for most China SEO and PPC strategies. But Chinese users also search through 360 Search, Sogou, Shenma, Bing, WeChat, RED, Douyin, Zhihu and marketplace search. That fragmentation means brands should understand where different audiences ask different questions.
StatCounter data has consistently shown Baidu as China’s largest search engine, with 360 Search holding a smaller share. Share estimates vary by device and methodology, so use them as directional signals rather than perfect market truth.
Where 360 Search may fit
360 Search can be relevant for B2B categories, desktop research, software, security-adjacent audiences, industrial products, education, healthcare research and long-tail keywords. It may also offer lower competition for some paid-search terms compared with Baidu.
The only reliable way to know is to test. Audit current search results, competitor visibility, keyword volumes, paid placement options and landing-page performance. If the results are thin or irrelevant, keep 360 Search as a low-priority supplement.
- Consider it for: B2B research, desktop users, long-tail keywords and cost testing.
- Do not use it for: campaigns that still lack basic Baidu visibility or Chinese landing pages.
- Measure: lead quality, cost per inquiry, conversion and assisted search impact.
SEO basics for 360 Search
Many SEO fundamentals still apply: crawlable Chinese HTML, fast pages, clear titles, useful content, internal links, structured headings and trustworthy external signals. A website that is slow or inaccessible in mainland China will struggle across search engines, not just on Baidu.
Because 360 Search is smaller, do not create thin duplicate pages only for it. Build useful Chinese content around the buyer’s question and make the technical site healthy. Our Baidu SEO guide and China website technical guide cover the foundation.
PPC and landing-page testing
Paid search on 360 can be worth testing when Baidu costs are high or when long-tail terms show commercial intent. Start with a small keyword group, a dedicated Chinese landing page and clear tracking. Do not judge the channel by clicks alone.
Compare inquiry quality against Baidu and other sources. Are users asking serious questions? Do they match target industries? Do they progress to WeChat, demo, quote or sales call? If not, adjust keywords and landing-page copy before scaling.
How 360 differs from social search
Social search on RED, Douyin, WeChat and Zhihu is often discovery and validation-driven. Users may want reviews, tutorials, opinions or community proof. Classic search engines like 360 are more query-driven and may capture problem, supplier, standard or comparison searches.
A good China search strategy can use both. Social platforms build trust around lived experience and expert content; classic search captures direct intent. The content library should answer both emotional and technical questions.
Avoid overcomplicating the search stack
The danger with alternative search engines is distraction. If a company does not yet have Chinese landing pages, Baidu visibility, working analytics and sales follow-up, adding 360 Search will not solve the core problem.
Treat 360 Search as a second-layer experiment. Build the main China search foundation first, then test whether incremental search coverage improves qualified traffic or lowers acquisition cost.
The 2026 takeaway
Qihoo 360 Search deserves awareness, not hype. It can be a useful supplement for selected audiences and keywords, especially in B2B or long-tail research. But it should be measured against lead quality and commercial outcomes, not vanity traffic.
For most international brands, the right sequence is clear: make the Chinese site usable, build Baidu and content fundamentals, then test 360 Search where the data justifies the extra work.
