The Quick Stats give you an overview of your site’s performance, and you can find them at the top of every report.

The Quick Stats display the following metrics for the given time period:
For each stat, there is a percentage, which is the relative growth of the stat compared to the previous period. For instance, if you had 1,000 Visitors in the last 30 days and the percentage is positive 10%, that means your site got 10% more visitors than the preceding 30 days.
When you first install Independent Analytics, there won’t be any data old enough to make a comparison, so the percentage will default to 0%.
