Google Analytics 4 (GA4) vs Universal Analytics (UA): Your questions answered
Document differences between old and new metric definitions and observe them in parallel. Check collection conditions before combining trends.
Putting analytics into practice
Define event triggers, parameter meanings and exclusions. Page views, qualified enquiries and sales are separate stages and should not be combined as one conversion measure.
Checking the result
Verify events through a known test journey and exclude test records. Date page and collection changes so comparisons use consistent definitions.
