# Google-InspectionTool

Category: [Crawling & Indexing](https://seo-geo-glossary.com/en/glossary/category/crawling-indexing/) › [Crawlers & bots](https://seo-geo-glossary.com/en/glossary/category/crawling-indexing/crawlers-bots/)

**Google-InspectionTool** is a Google crawler used by testing tools for Search, including the Rich Results Test and the URL Inspection tool in Search Console. Google lists it among its common crawlers.

## What does it do?

When someone runs a live test in the URL Inspection tool, Google says the tool fetches and examines the URL in real time. The help page names Google-InspectionTool as the crawler for such tests. The field "Crawled as" shows whether the desktop or smartphone user agent was used.

Google names `Google-InspectionTool` or `Googlebot` as robots.txt token. Google documents a desktop and a mobile user agent that both contain the string `Google-InspectionTool/1.0`.

```txt
Mozilla/5.0 (compatible; Google-InspectionTool/1.0)
```

The live test does not check every possible indexing issue. According to the help page, it cannot tell whether a page is a duplicate or an alternate version and does not detect manual actions.

## In logfiles

Requests with this user agent come from tests that someone with access to Search Console or the testing tool started. They are not part of regular Googlebot crawling, so it makes sense to look at them separately (assessment).

## Example

An SEO runs a live test for a new product page and the server log records one request from `Google-InspectionTool`. Further requests from the same IP range follow only when someone starts another test. (Invented example.)
