Segment Summary FAQ

What this Report Does:

The Segment Summary provides a view into how a given segment is composed. It shows the number of devices included and two views of people: those we know we can surely identify as tied to a device (determined from your own login information), and those we predict are tied to a device (determined by probabilistic matching from people seen elsewhere in the Salesforce Audience Studio ecosystem). A large variance between people and devices would conclude that we were not able to identify enough information to calculate people with confidence.
