How it operates

Worth a slow read.Distillation is no fixed dial. How it behaves depends on your audience, your channel mix, and the strategy around it.

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

The working rule is plain. Agree what Distillation covers first, then act on it. Skip that order and Distillation loses its shared meaning, and two teams end up measuring two different things. Read that twice.
