How to block 360Spider
360Spider is the crawler for so.com, the search engine operated by Qihoo 360 in China. This page shows how to disallow 360Spider in robots.txt, confirms what a block affects, and how to check the crawler honours it.
robots.txt rule
Qihoo 360's crawler identifies with the 360Spider token. To disallow it site-wide:
User-agent: 360Spider Disallow: /
Confirm the exact token from your access logs, because Qihoo operates more than one crawler and a single token may not cover image or other specialised fetchers. Match on the documented token, not a full version string.
- robots.txt token: 360Spider
- Qihoo may run additional specialised tokens
- Verify the token set from your logs
Scope and limits
Blocking 360Spider affects only Qihoo 360's so.com crawler; Baidu, Google, and Bing are unaffected and keep their own tokens. A Disallow does not remove pages already in so.com — use noindex on a fetchable URL for that.
Because the user agent can be copied, persistent hits after a correct rule may indicate a non-compliant scraper rather than the genuine 360Spider, which compliant-crawler etiquette would have stopped.
How it appears in analytics and logs
360Spider hits indicate Qihoo 360 is crawling for so.com. If they continue after a Disallow, suspect a token mismatch, a cached robots.txt, or a spoofed user agent.
Diagnostic use case
Reduce crawl from 360Spider on sites without a Chinese so.com audience, or keep specific paths out of Qihoo 360's index.
What WebmasterID can help detect
WebmasterID logs 360Spider activity as a search bot, so you can see whether crawl volume drops after the rule is added — the observable proof that it is being respected.
Common mistakes
- Blocking 360Spider but leaving Baiduspider crawling, assuming one covers China.
- Missing a secondary Qihoo token for images or other content.
- Expecting the Disallow to de-index existing so.com results.
Privacy and accuracy notes
The rule targets the 360Spider crawler token and involves no visitor data. robots.txt is a request to compliant crawlers, not an enforcement layer.
