There is no need to explain you the importance of Internet and Business... I know you know.
But maybe something you don't know is that for being able to follow what makes your web site "the envy" of the others you need some tools that can track statistics. The best software available is called Web Trends.
The bad news is that I tried a free trial they offer from their web site... and I have to tell you: don't use their free trial period. If you are not very careful it will cost you 35$.
The gooood news is that I passed the bad experience... now you can avoid it.
