Baiduspider-mobile
Baiduspider-mobile is a search-engine crawler operated by Baidu. 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.

1Should I let Baiduspider-mobile 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 Baiduspider-mobile affect my Google rankings?
Only on Baidu Baiduspider-mobile feeds. Each search engine runs its own crawler, so blocking Baiduspider-mobile 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 Baiduspider-mobile?
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 Baiduspider-mobile", not "the traffic is genuinely Baiduspider-mobile". If you need stronger guarantees, look for a reverse-DNS check or wait for Baidu to publish IP ranges.
What happens to my traffic if I block Baiduspider-mobile?
Your pages drop out of Baidu's index, which means losing the organic share you get from that engine. Not catastrophic if Baidu is a minor player, much more painful if it's a meaningful source of your traffic. Check your analytics for Baidu's actual referral share before deciding.
How is Baiduspider-mobile different from Baidu's other bots?
Baidu splits work across multiple user-agents so site owners can decide on each one independently. Training crawlers, live-fetch agents, search indexers, and agentic browsers each get their own name. Worth scanning the rest of the Baidu family above to see which ones actually matter for your site.
What's the cleanest way to control Baiduspider-mobile?
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.
