The legal stuff...
An "Itinerary View” is defined as unique access of a single web builder itinerary, web shareable itinerary, PDF download itinerary, mobile application itinerary, or embedded itinerary per method and device per day. A “Day” means a period of time from midnight to midnight, Coordinated Universal Time (UTC).
In plain English...
Whenever anyone views a unique itinerary this counts as a view. However, we only count one view per method and device per day.
As an example, if you have a client who views the same itinerary on their phone via mobile app 45 times in a given day, this counts as 1 view.
