Consent script latency
Page-load or interaction-readiness delay introduced by consent-management scripts and blocked third-party tags.
Consent script latency captures the performance cost of the consent stack. Measure CMP script load time, main-thread blocking, and any added delay to first contentful paint or first interaction.
For journey-blocking consent, the UI can harm the journey even before the user makes a privacy choice if the CMP delays content or input readiness.
