Reported user-agent
Google-Firebase
Google-Firebase access decides whether Google can fetch your pages. Whether those pages get used in generated answers is a separate question, so track your presence in Google's AI results rather than treating crawl volume as visibility.
robots.txt allow example
User-agent: Google-Firebase Allow: /
robots.txt block example
User-agent: Google-Firebase Disallow: /
What the rule can and cannot do
Robots.txt expresses an access policy to compliant automated crawlers. It does not authenticate the sender, remove content already collected, or guarantee that a model will use or not use content.
How to verify a request
- Match the complete documented user-agent where one exists. A match is only a clue.
- Look for operator-published IP ranges, reverse DNS, or signed-request guidance. None is attached to this record.
- Keep the observed request, operator documentation, and any inference as separate fields.
JavaScript behavior
The cited operator material does not verify JavaScript rendering. Serve useful HTML before client-side JavaScript where possible.
