What is a Campaign?
Campaign are simply a group of events
Campaigns are a good way to group events. For example, if you have a tour with 5 events during the tour you can organize all of those 5 events into a campaign so you can view all of the analytics combined in one report.
How do I set up a campaign?
You can add any number of events to a campaign by selecting the events on the event list page and clicking "Create Campaign"
Once a campaign has been created - you can view it on the Campaign list page. From there it will give you an analytics report of all the events in the campaign grouped together.
