The folks over at Sellsius are recommending Clicky as an alternative web analytics package. I currently use Google Analytics and it's great – but it's still a little difficult to get around and drill down on the data you need. The screenshots for Clicky look fantastic, I can't wait to dig in.
This may be a package that I recommend to all my clients – it's free to sign up. You can upgrade to the professional version for just $2 per month!
