Specify the data you would collect (campaign, user/geo, survey, market, external).
Propose study designs (e.g., lift studies, matched-market tests, MMM) and the metrics you would use.
Detail the statistical tests/estimators and how you would construct confidence intervals.
Explain how you would validate or refute the spend hypothesis and control for confounding.
