Google-InspectionTool

You cause this one yourself. It fetches when a site owner runs a Search Console check, so preferences addressed to it affect testing tools such as the Rich Result Test and URL inspection. That makes it diagnostic traffic on demand: a live re-fetch performed so the tool can show what Google would see right now, rather than replaying a cached copy. It resembles Googlebot closely by design, because reproducing Googlebot's view is the entire point of the exercise, but nothing it retrieves is indexed or ranked.

How to verify Google-InspectionTool

Google publishes the IP ranges Google-InspectionTool crawls from, and we fetch that list on a schedule. A request claiming to be Google-InspectionTool can therefore be checked against 2,163 published ranges: one that does not match is not this crawler.

Published ranges last confirmed by us on .

Google documents reverse-DNS verification: a genuine request resolves to a hostname under .googlebot.com or .geo.googlebot.com that forward-resolves back to the same address.

User agent

Google publishes this user agent for Google-InspectionTool. Match on the Google-InspectionTool product token rather than the whole string: vendors revise the surrounding version and URL fragments without notice.

robots.txt is a request, not an enforcement mechanism. It is honoured by convention, and a crawler that ignores it is stopped at your edge, not in a text file.

What blocking Google-InspectionTool costs you

The victim of this block is your own SEO team. Disallow it and Test Live URL, the Rich Result Test and structured-data validation begin reporting your pages as blocked or unfetchable, so you lose the ability to debug indexing and rich-result eligibility, while your actual rankings, unhelpfully, carry on unchanged. It is a self-inflicted blindfold: the symptom is a broken diagnostic and the natural but wrong conclusion is that something is wrong with the page. Volume is trivially low, since it only fires when a human clicks a button, so there is no crawl-budget argument either.
