What is Google-InspectionTool?

The crawler used by the URL Inspection tool in Google Search Console. It mimics Googlebot to show you how Google sees your page.

The crawler used by the URL Inspection tool in Google Search Console. It mimics Googlebot to show you how Google sees your page. Google-InspectionTool is one of Google's specialised crawlers, distinct from the general Googlebot. It serves a specific Google product (Images, Video, News, etc.) and uses the user-agent Google-InspectionTool. Selectively blocking it disables the corresponding Google feature for your site (e.g., blocking Googlebot-Image removes your images from Google Image Search). Always verify which Google product is affected before blocking.

What happens if you block Google-InspectionTool?

⛔ **Critical Impact** — Blocking Google-InspectionTool will stop Google from crawling and indexing your pages. Within days or weeks you may see pages drop out of Google's search index entirely, resulting in a significant loss of organic search traffic. This is the most severe possible SEO consequence. Only do this intentionally, for example if you are migrating to a different search engine or decommissioning a domain. If you accidentally blocked Google-InspectionTool, remove the rule immediately and request re-indexing via Google's webmaster tools.
Never block — it will remove your site from major search results.

You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For Google-InspectionTool specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).

User-agent: Google-InspectionTool
Disallow: /private/
Disallow: /staging/
Allow: /
This allows Google-InspectionTool everywhere except the listed paths. Path matching in robots.txt uses prefix matching — Disallow: /private/ blocks /private/page.html but NOT /public/private/.
