In this section, you can compare your statistics during two separate time periods in one chart. For example, you can compare your CTR from the current week to the CTR from the previous week.
You can filter your statistics according to revenue, clicks, impressions, CTR, or eCPM via the drop-down menu in the top right-hand corner. In addition, you can filter based on daily statistics, weekly statistics, or monthly statistics.
In the top left-hand corner, use the drop down menu to create a custom date range to compare or select ‘Previous Period’ to view the statistics from the most recent week or month. If 'Custom Date' is selected, you will be able to click on From and a calendar of dates will appear for you to choose from.
Once you have selected a date range, you will see both ranges listed on the top of the chart. By clicking on either one of these date ranges, you can ‘turn off’ the data. Click on the date range again to make the data re-appear.
