What is a Signal?

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

• Starts with a quotation mark.
• Starts with an underscore (_)

The following are legitimate examples

• "1"="key value"
• Alpha=22
• E1=456
• "1a"="key value"
• _color=red

Don'ts for signal keys -

• Start with a number
• Have a special character.
