http://www.google.com/analytics/ http://www.google.com/analytics/ probably does 90% of what you need; add a more user-focused analytics program (there are plenty) and you'll probably get more than you need, executed better than you could yourself. ps: the inability of many developers to go with a "good enough" solution or to question "requirements" always baffles me. What you think are requirements are probably just rough guesses at what the client might want (I know, I've been writing requirements for a living for 10 years). This sounds like exactly a case of that, although I may be wrong of course.
