Privacy
Consent, tracking prevention, and what regulation does to measurement in practice.
Privacy rules and browser restrictions change what can be measured. Consent, tracking prevention and regulation each reduce the data that arrives, and each does it in a different way. This topic covers how those limits work in practice, what they do to conversion counts, and which limits are legal rules, which are browser defaults and which are choices a team makes. The pieces describe mechanisms, not legal advice.
