Analytics, Traffic and Website Statistics
To get a bit more complex, we use the infamous Google Analytics for a more robust statistical analysis. With Google Analytics, the website owner is able to really drill down into the traffic, setup element of traffic monitoring in order to optimize your traffic and learn to manipulate your site with hopes of controlling your traffic and visitors.
The Dashboard information gives a great snapshot of how you're ranked with visitors over the last month. The great thing about Google Analytics is that you delve deeper (to what seems like endless metrics) into each piece to understand and target your traffic even further. A few other reports that I keep a regular eye on include: Visitor Report, Traffic Sources, Keywords, Content Overview.
