this thread isn't doing clicktale justice by a long shot.
if you haven't seen it, try it.
it's thoroughly badass analytics.
step-by-step video recording of everything your visitor does is a metrics junkie's wet dream.
it's a little bit evil. possibly a lot of bit evil.
but nothing has come closer to putting you inside customer's heads than clicktale.
and for that, it deserves some serious +rep.
in conclusion, see sig.
thanks,
your friendly clicktale user, lover, and affiliate
