What is Category-based Script Blocking?

A technical method used by Consent Management Platforms to group tracking scripts (e.g., ‘Analytics,’ ‘Marketing’) and conditionally load them based on user consent choices.

 

This technique ensures granular consent requirements are met, as a user can opt-in to ‘Analytics’ but reject ‘Marketing’ scripts. This is the core technical function of a compliant CMP, relying on integration with the Cookie Consent GTM.

 

The operational necessity is preventing the initialisation of scripts before the CMP receives the user’s consent signal, thereby preventing data leakage.
