Consent Mode v2 Checker

Verify your site has Google Consent Mode v2 defaults set, consent updates firing, and optionally IAB TCF 2.3 implemented.

Why GCM v2 matters

Without Consent Mode v2, Google Analytics and Ads cannot use modeled conversions for users who decline cookies. This means you lose data accuracy and ad targeting effectiveness for EU/UK users — even when using a consent banner.

This tool checks static HTML only. GCM v2 implemented via GTM may not be fully detected without JavaScript execution.
