It can be fascinating watching trends in webhits. Somebody today put a link to the older feathers page in an email and mass-mailed it. I'm suddenly seeing scores of webhits from all over the globe. It's fascinating to watch the progression of this forwarded link and all its destinations.
Following webhits, geography, etc. is very helpful. You can track what "advertising" is proving to be most effective. Additionally, I tend to see more direct hits or hits through searches coming from a particular area that I've sent work to recently, be it a commission or whatever.
