      Did this work?

      What happened because of the ads?

      Here’s the math I’d walk a finance partner through. Pause ads in a few markets, keep them running everywhere else, and compare the gap against how those same markets behaved before the test. Then ask how sure you can be. Pick markets, run six simulated weeks, and every step of the math appears below the result.

      • Ads continue
      • Ads paused
      • Markets still running ads

      1 · Choose holdout markets

      Ads pause in the markets you select and continue everywhere else.

      2 · Run the simulation

      3 · Read the result

      Choose markets, then run the simulation.

      Markets and sales are simulated. The effect is the share of sales in the paused markets that went away, read as a ratio against the markets that kept spending, before versus after (a difference-in-differences ratio). The 95% interval accounts for noise in both periods and uses a t-distribution because there are only twelve weeks. It illustrates the logic; it doesn’t design or validate a real experiment.
