Disallow: /Frequently Asked Questions
Should I Block 360Spider?
No, unless you want your pages out of search results. 360Spider 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. For comparison, 2% of the top websites we track already have robots.txt rules for 360Spider.
Does 360Spider Respect Robots.txt?
Yes. 360Spider 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 360Spider actually honors it.
Does 360Spider Access Private Content?
No. 360Spider 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.
Why Is 360Spider Visiting My Website?
360Spider is keeping its search index current. Links, sitemaps, or direct submission brought it to your site, and it comes back at a rate tuned to how often your content changes and how popular your site is.
How Can I Tell if 360Spider Is Visiting My Website?
Agent Analytics tracks 360Spider visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "360Spider". Look for steady recurring visits spread across your site. Keep in mind that 360Spider doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
