Linking Tactics to Creatives
A tactic must be linked to at least one creative before it can go live. The tactic controls where and when the creative is shown, while the creative controls the content that is shown to the user and what happens when the user interacts with that content.
A tactic can use any number of creatives, and an creative can be used by any number of tactics.
When you create a new tactic or edit an existing tactic, you link it to creatives on the Creative tab.
