The dashboard helps you compare the metrics that define your paid marketing.
For example, you can see the amount spent for a specific time period, the number of visits, cart sessions, transactions, cost per order right up to RoAS.
You can also compare the performance between specific date ranges.
Last 30-days comparison:
Select the last 30-days filter from the drop down and it will show you the relative numbers for the top metrics.
The percentages in red and green indicate the decrease or increase in a metric in comparison with the preceding time frame (in this case last 30 days)
For example – If the metric for comparison is transactions. A percentage quoting 2.6% in green means that the transactions are up by 2.6% from the last 30 days.
