How it works

One idea, plainly put.Didomi produces value through how it is applied. Change the inputs and the right use of it changes too.

Didomi is not a switch you flip. It names a moving idea, and the way it plays out shifts with the setup. A lean team running one paid channel applies Didomi differently than a brand running ten. Use Didomi loosely and teams pull apart; pin it down and the math lines up.

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

Where it shows up

  2. Choosing a metric. Didomi reveals if the metric measures real impact.
  3. Comparing options. Didomi corrects two options that look alike but are not.

Worked example

Start here.Below, Didomi is put inside a The New York Times setting -- real trade-offs, a clear baseline, and a figure to test it.

Take The New York Times. During a first-party data shift, the team made Didomi the deciding input, not an afterthought. They set a baseline first, agreed one definition of Didomi, and only then read the result: logged-in readers passed 60% of ad revenue. The number matters less than the order.
