A derived signal qualifies site visitors for additional traits based on a trait they’ve already seen. In other words, additional trait qualification can be derived from a currently exhibited trait even if a user has never seen the new trait before.
In Audience Manager, you can create a relationship between signals (or trait rules) passed in during an event call to other, specified signals or traits. For example, assume an event call passes in a signal composed of the key-value “product = new_car” (
https://<domain alias>/event?product=new_car). Audience Manager would connect that signal to any others created with the derived signals tool. Although the associated signals can be any key-values you specify, they are most useful when linked to existing signals already set up as Trait Builder rules. For example, in the illustration below, when a user action fires the signal “product = new car” that user can also qualify for traits defined by the target key and value signals.
Create and manage derived signals in Tools > Derived Signals from the sidebar navigation.
