Signals are the smallest data units in Audience Manager and are expressed as key-value pairs.
- The key is a constant that defines a data set (e.g., gender, color, price).
- The value is a variable related to the constant (e.g., male/female, green, 100).
Comparison operators join the key-value pair and set the relationship between them. In simple terms “A signal is a key-value pair that identifies certain web activity”.
