Campaign performance presents all performance data for the jobs linked to the campaign. When looking at the view "Campaign" you can see the aggregated campaign performance data. Campaign data is especially useful when wanting to look at data at an aggregated level.
When choosing "Per job" instead you can see all data separated per job instead.
The section "Quality" displays performance data linked to the quality of the job such as Content completion rate, video retention, and link clicks.
For data such as attribution page views and attribution event, you need to have an attribution node implemented.
"Reach and volume" displays performance data linked to distribution such as frequency, cost per view and reach. For Cost per page view and video view, you need to add a budget in the settings section under Campaign.
Demography shows the gender and age distribution in absolute numbers.
