Comparison columns
Voluum allows you to compare data sets from any time ranges. You can compare last week's data with data from five days before that. The compared periods of time can even overlap with each other. This allows you to see the effects of your optimization efforts or changes made in targeting settings in your traffic source platform more clearly.
Voluum executes this functionality by introducing two features:
Comparison columns
Previous time range in the chart
Read the following article to learn how these features work and how you can use them in your day-to-day work with Voluum.

Reading comparison columns

In each comparison column you will see two values:
The first one is a percentage difference which can be of positive or negative value. This value displays the size of the change.
The second one is an absolute number which can be of positive or negative value. This value shows the difference between the last time range's value and the current time range's value.
