Traffic reports let you analyze your website traffic by providing relevant data, such as the total number of visits to your site, the number of times users have visited a specific page, the deviation rate of particular pages, and referrers.
To view your website's traffic statistics:
Select Reports -> Traffic Reports.
In the Page Visits section, you can view the page visits by clicking the drop-down list at the top of the screen to filter your view by day, week, month, or year.
Referrers report shows the list of referrers from where the traffic has been redirected to your website.

Percentage (%) data such as 20% or 50% represents a change in trend over a selected period (daily, weekly, monthly, or yearly).
