Experiments

Hold out a market. Read the lift.

What it does

  1. 01

    Geo-lift incrementality tests: pick the DMAs, hold some out, run the treatment in the rest, read the lift with a confidence interval.

  2. 02

    Synthetic evaluations when a clean holdout is not possible; causal-impact reads for what already happened.

  3. 03

    Shareable results — the finding, the method, the interval — for the people who were not in the room.

Why it exists

Built because attribution reports are the platform grading its own homework.

The science behind it

The measurement sits under the platform: geo-lifts with a holdout, models calibrated on them, guardrails written in code. Read the method.
