What is Google Inspection Tool?

Direct Answer: Google Inspection Tool is a crawler used by Google for Search testing tools, operated by Google.

Operator: Google Type: Security Scanner Purpose: Search testing and validation

Google-InspectionTool is a crawler used by Search testing tools such as the Rich Result Test and URL inspection in Search Console. It mimics Googlebot apart from the user agent and user agent token. This crawler is used for specific testing purposes and does not follow the standard Googlebot behavior in all aspects.

User-Agent Identification

The following user-agent strings identify Google Inspection Tool in your live traffic data:

  • Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.5672.92 Mobile Safari/537.36 (compatible; Google-InspectionTool/1.0;)

robots.txt Rules for Google Inspection Tool

Respects robots.txt: No

Robots.txt has limited effect on user-initiated bots

Google Inspection Tool is triggered by user actions within Google's products. While Google states it respects robots.txt, the bot operates differently from autonomous crawlers — it fetches specific URLs on demand rather than systematically spidering your site. Server-log monitoring is the only reliable way to verify what actually happens.

  1. Search access logs for the user-agent strings listed above
