Expected Behavior
AccessibleWebBot's pattern depends on who pointed it at you. Continuous monitoring services check daily or even hourly, while a one time assessment sweeps once and disappears. Expect requests aimed at login pages, admin paths, APIs, and configuration files, because exposed ones are what scanners exist to find.

Frequently Asked Questions
Should I Block AccessibleWebBot?
Not unless you already run your own scanning and want cleaner logs. AccessibleWebBot checks websites for exposed vulnerabilities, and some scanning services report what they find to site owners for free. Almost none of the top websites we track have robots.txt rules for AccessibleWebBot right now.
Does AccessibleWebBot Follow Robots.txt Rules?
Yes. AccessibleWebBot is expected to follow 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 AccessibleWebBot actually follows it.
Does AccessibleWebBot Access Private Content?
It probes for private content deliberately. Login pages, admin panels, and API endpoints are exactly what AccessibleWebBot tests, because exposed ones are what it exists to find. Probing is not the same as getting in, but expect requests to sensitive paths in your logs.
Why Is AccessibleWebBot Visiting My Website?
AccessibleWebBot is scanning your site for vulnerabilities, either as part of a sweep across the whole internet or because someone requested an assessment of your domain. Recurring visits usually mean a monitoring service has you on its list.
How Can I Tell if AccessibleWebBot Is Visiting My Website?
Agent Analytics tracks AccessibleWebBot 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 "AccessibleWebBot". Look for probes of login, admin, and API paths. Keep in mind that AccessibleWebBot 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.
