Frequently Asked Questions
Should I Block Google-InspectionTool?
Usually not, unless you already run your own security scans and want cleaner logs. Google-InspectionTool checks for exposed vulnerabilities, and some services report their findings to site owners at no cost. For context, 4% of the top websites we track currently have robots.txt rules for Google-InspectionTool.
Does Google-InspectionTool Follow Robots.txt Rules?
Yes. Google-InspectionTool is expected to follow robots.txt rules, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Google-InspectionTool respects it.
Does Google-InspectionTool Access Private Content?
It deliberately looks for exposed private content. Google-InspectionTool tests login pages, admin panels, and API endpoints for vulnerabilities. Probing does not mean it gained access, but you should expect requests to sensitive paths in your logs.
How Can I Tell if Google-InspectionTool Is Visiting My Website?
Agent Analytics tracks Google-InspectionTool visits in real time. You can also check your server logs for requests whose user-agent string contains "Google-InspectionTool". Look for bursts of requests to uncommon paths that ordinary visitors rarely access. Because Google-InspectionTool does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is Google-InspectionTool Visiting My Website?
Google-InspectionTool is scanning your site for vulnerabilities, either as part of an internet-wide sweep or because someone requested an assessment of your domain. Recurring visits often indicate that a monitoring service has added your site to its checks.
