Which feature identifies the number of targets in a segment?

• A. Count Segment
• B. Segment
• C. Attribute Library
• D. Publish

Answer: (A)

The key idea is measuring how many individuals fall into a defined group. The Count Segment feature performs that exact job: it tallies all members who meet the segment’s rules and returns the size of the audience. This makes it the go-to way to know how many targets you’ll reach, which informs planning, budgeting, and expected impact.

The other options serve different purposes. Defining or referencing a segment describes the group itself, not its size. An Attribute Library stores the data attributes used to describe people and build segments. Publishing moves the segment into use, such as making it available for campaigns, but it doesn’t tell you how many people are included.
