Allow or block GoogleOther
User-agent: GoogleOther
Disallow: /Asks GoogleOther not to crawl any page. Well-behaved crawlers stop; it does not stop anyone who ignores robots.txt.
User-agent: GoogleOther
Allow: /Lets GoogleOther crawl everything. You only need this if a broader rule would otherwise block it.
Should you block it?
GoogleOther is not an AI training or AI search crawler. Block it only if you don't want Google's product to read your pages.
