Estimate the impact of moving to Google Consent Mode on GA4 by comparing key metrics before vs. after consent. Quantify expected data loss by adjusting consent acceptance rates and seeing changes to users, sessions, views, transactions, revenue, and tracked actions. Identify eligibility for GA4 behavioral modelling and monitor denied events and average daily users to understand modelling coverage. Use the modelling breakdown to communicate the expected impact period and magnitude to stakeholders. Ideal for teams evaluating a Consent Mode migration and its effect on reporting and conversions.
