It's simple: Google has access to the referrer URL when you go onto their website. It's well known that they index these URLs.
If you go from that Facebook page straight to Google, it'll get indexed.

- sounddust 16y agoIn what situation would the HTTP referrer header report Google when clicking away from a Facebook link? Not only is there no Google search field on Facebook, but Facebook also reroutes links through an intermediary page in order to hide the actual referring page.
- tcoxon 16y agoI had assumed that Referer URLs were sent even if it wasn't from a link that was clicked. That's not true. (And yes, "Referer" is misspelt in the standard...) http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html > The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard.
