Signals are the atomic 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.
A few examples of signals are -
- product=cycle
- price>500
- type=mountain
