A webmaster needs to monitor unique visitors, page views, time on site, advertising dollars received or conversions to be successful.
You could also say, you cannot expect, what you do not inspect.
Many people use Google Analytics for site statistics, and yes this system does create good stats, the question is this,
"Do you open your google analytics everyday?"
If the answer is yes, then you are fine, if the answer is no, there is a problem.
