Once your campaign has started to deliver you will be able to track it's performance via the media schedule section under the 'delivery' tab.
There are multiple options available to obtain your delivery data through the media schedule.
Simply navigate to the placement which has data populated against it and roll over the cell until you see the blue arrows appear. Click on the arrows for the report to appear.
This report can be split by a specific period and to gain a granular insight simply roll over the graphs for the information to appear.
Note: Buyer data is not always available in this report as it has to be manually entered. The same may also apply to the seller data.
The other option available to gain access to the delivery data is via the 'Download Delivery Data' link located towards the bottom of your media schedule. Please refer to below image for further information.
