Google Consent Mode allows website owners to manage how Google's services interact with users based on their consent choices. Specifically, it modifies the behaviour of Google's advertising and analytics scripts to align with user preferences about cookies and data collection.
This mode ensures that user decisions regarding ad personalisation and analytics cookies are respected. If a user declines consent for cookies, Google services will adjust their operations to avoid using cookies that track personal data, yet still provide the website with aggregated insights and ad performance metrics without identifying individual users.
