360Spider
360Spider is a search-engine crawler operated by Qihoo. Its job is to find, fetch, and index web pages so they can be returned in organic search results.
Traffic is regular and bounded by your robots.txt. Allowing it is generally how your site stays discoverable through the corresponding search engine, blocking it almost always reduces visibility there.
For most sites, search-engine crawlers are still the largest source of bot traffic and the largest source of human visitors that follow.

For higher confidence, also verify the source IP against the operator's published ranges. UA strings can be spoofed; IP ownership is harder to fake.

Should I let 360Spider through?
In most cases, yes. Blocking traditional search crawlers reduces organic-search visibility. Allowing is the default for almost all sites. If volume gets noisy, rate-limit it before you block it outright.
Does blocking 360Spider affect my Google rankings?
Only on Qihoo 360Spider feeds. Each search engine runs its own crawler, so blocking 360Spider only removes you from that one index. Your visibility on Google, Bing, or anything else is untouched.
How do I confirm a request is really from 360Spider?
Look at the User-Agent header in your access logs and match it against the strings listed above. Worth knowing that the User-Agent is easy to fake, so this check tells you "the traffic claims to be 360Spider", not "the traffic is genuinely 360Spider". If you need stronger guarantees, look for a reverse-DNS check or wait for Qihoo to publish IP ranges.
What happens to my traffic if I block 360Spider?
Your pages drop out of Qihoo's index, which means losing the organic share you get from that engine. Not catastrophic if Qihoo is a minor player, much more painful if it's a meaningful source of your traffic. Check your analytics for Qihoo's actual referral share before deciding.
What's the cleanest way to control 360Spider?
Two layers. Robots.txt for the polite crawlers that read it, and rules at your CDN or edge for the ones that don't. Rankly's Agent Experience handles both from a single config, so you can allow, block, rate-limit, or serve a stripped-down version per bot. Agent Analytics handles the observation half so you know which bots are actually worth a rule.
