It does depend. I've got authoraitve site links for
The Gospel According To Rhys when you search for "gospelrhys". Personally, I can't see it being successful, as
a) Not many people search for it
b) the site links aren't that useful.
I'm quite pleased though one of my site links have the word "bugger" in it
The funny thing is that for a search I did last week (I think it was something to do with ten pin bowling), and one of the site links was the 404 page.
