NexusConsent

This guide shows how to put a standard Google Analytics 4 (GA4) tag behind NexusConsent on Joomla 5 or 6, and how to check that it follows the visitor's choice. If you use Google Tag Manager (GTM), also read the GTM section below.

Consent Mode tells supported Google tags which storage and advertising uses the visitor has allowed. A loaded Google tag can still send measurements without cookies when storage consent is denied. Blocking the tag until consent is a separate step. Google's Consent Mode overview explains the distinction.

Under GDPR, tracking scripts must not run before a visitor agrees. Adding a cookie banner isn't enough on its own. If Analytics loads while the banner is still on screen, you've already tracked someone who never agreed.

GDPR Article 7(1) puts the burden on you. If a visitor's consent is ever questioned, you have to demonstrate that it was given. A banner on the screen proves nothing after the fact.
