New Googlebot: Google-InspectionTool Added To Crawler User Agents


In an exciting development for webmasters and SEO professionals, Google has introduced a new addition to its lineup of crawler user agents – the Google-InspectionTool. This recent inclusion provides enhanced capabilities for search testing, enabling more accurate analysis of website performance and search results. Let’s delve deeper into this new Googlebot and its implications for website owners.

Enhanced Search Testing:

Google-InspectionTool, as the name suggests, is primarily designed as a crawler for search testing purposes. It powers essential tools such as the Rich Result Test and URL inspection in Search Console. With this addition, website owners now have access to a specialized crawler that accurately mimics Googlebot’s behavior, ensuring more precise insights into how their site is indexed and displayed in search results.

User Agent Tokens and Strings:

To identify and differentiate the Google-InspectionTool from other user agents, it operates under two distinctive user agent tokens: “Google-InspectionTool” and “Googlebot.” This allows webmasters to easily identify the crawler’s activity within their server logs or analytics tools. Additionally, Google-InspectionTool boasts two comprehensive user agent strings—one for mobile and another for desktop.

For mobile devices, the user agent string is as follows: Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/W.X.Y.Z Mobile Safari/537.36 (compatible; Google-InspectionTool/1.0)

And for desktop systems, the user agent string is: Mozilla/5.0 (compatible; Google-InspectionTool/1.0)

John Mueller’s Confirmation:

John Mueller, a well-known figure at Google, recently confirmed the addition of Google-InspectionTool via a Mastodon post. In his announcement, Mueller stated, “The update is now complete—the new user-agent names are in.” This confirmation from a trusted source within Google affirms the authenticity and significance of the new user agent.

Improved Testing and Website Optimization:

The introduction of Google-InspectionTool brings exciting possibilities for website owners and SEO professionals. It allows for more accurate testing of website features, structured data, and overall search performance. By leveraging the specialized crawler, webmasters can fine-tune their websites, identify and resolve any issues, and optimize their content to improve search visibility and user experience.


With the addition of Google-InspectionTool to Google’s list of crawler user agents, website owners now have an advanced toolset to conduct thorough search testing and analysis. This specialized crawler, which operates under the user agent names Google-InspectionTool and Googlebot, provides valuable insights into website indexing, search result display, and overall performance. As webmasters harness the power of this new Googlebot, they can refine their websites, enhance search visibility, and deliver an improved user experience. Stay ahead of the game by utilizing Google-InspectionTool and reaping the benefits of optimized online presence.
