Overall Trend Graph
By default, this graph shows a breakdown of visits per day over the span of one month. Above the trend graph you will find different filters to choose from.
Site Usage Statistics
A high level view of the visitors that came to your site, how many pages they saw, how long they stayed, how many left from the same page they landed on, and how many had been there before they left.
Although the default report shows you a month's activity, you can change the length of time or even measure your previous month's activity against the same time the previous year.
To understand your web site statistics, you will need to be familiar with a few key terms.
