The mechanics

Pick one definition.ID5 ID is no fixed dial. How it behaves depends on your audience, your channel mix, and the strategy around it.

ID5 ID behaves unlike a fixed rule. An early-stage brand and a mature one will apply ID5 ID on different terms. The mechanics follow the inputs around it. Treat ID5 ID as a buzzword and the reporting misleads; agree on it and the numbers hold.

One rule always holds. Settle the scope of ID5 ID up front, then build the plan. Get it backwards and ID5 ID becomes a word everyone uses and no one shares. Pick one definition.
