Should I Block Baiduspider-render?
No, unless you want your pages out of search results. Baiduspider-render feeds a search engine index, and blocking it erases your visibility and organic traffic from that engine. This is the one category almost every website should allow. Almost none of the top websites we track have robots.txt rules for Baiduspider-render right now.
Does Baiduspider-render Respect Robots.txt?
Yes. Baiduspider-render is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms Baiduspider-render actually honors it.
Does Baiduspider-render Access Private Content?
No. Baiduspider-render indexes public pages only and does not sign in anywhere. Watch for accidentally public content though, because anything reachable without a login can end up in search results.
