The technical integration of a Consent Management Platform (CMP) with Google Tag Manager (GTM) to ensure tracking tags only fire after user consent is obtained.

This is the crucial technical bridge for operational compliance. The CMP updates GTM’s data layer with the user’s consent status, which then informs GTM’s built-in triggers or Consent Mode v2 parameters.

This conditional loading is what ensures tracking scripts are blocked pre-consent. Misconfiguration means tags fire regardless of consent, leading to a violation. Correct implementation with tools like Seers.ai ensures tags are fired selectively and legally.
