Googlebot User Agent String

This page prefills the parser with the real, current smartphone Googlebot user-agent string as Google documents it, and decodes it on load. Unlike the browser examples on this tool, the point here is not a browser and OS readout for a person — it is confirming exactly what Google's crawler identifies itself as, which is precisely what webmasters need when writing robots.txt rules or filtering crawler traffic out of analytics and server logs.

The breakdown shows the known-bot flag set to yes with 'Googlebot' as the matched name, alongside the Android/Chrome-based identity the crawler wraps itself in (Google's crawler renders pages using a real Chromium engine, which is why the string looks like an Android phone running Chrome, with '(compatible; Googlebot/2.1; +http://www.google.com/bot.html)' appended as the tell). This is a different job from checking what browser a human visitor is using — Googlebot is not a browser at all, and the separate What Is My Browser tool would not help identify it since that page only ever reports on the browser you are personally reading it in.

Clear the box and paste in any other UA string from your own server logs — another search engine's crawler, an SEO tool's bot, or a suspicious line you want to double-check — to see the same known-bot detection applied, with an honest 'no' whenever nothing in the dozens of known crawler patterns matches.
