I think that is exactly part of answering the question "what info you are looking for". For the most part Google Analytics will get you what you need, although I also use www.hittail.com
because I like the keyword reporting it provides. Google Analytics can provide a lot of the same information, if I dig to the page level view and look at keyword referrals.
For more about hittail, see this thread about it here -
Part of asking, I guess, is a check to make sure we're not missing something by just relying on GA. For the most part, I don't think most are.
If anything, does anyone here do conversion tracking and if so how? that is usually the least lacking aspect of analytics imo. and if that is addressed, are you tracking offline also - such as phone calls. anyone?
