Google Consent Mode v2 Debugger

Google Consent Mode v2 is a framework that adjusts how Google tags behave based on user consent. It requires four consent types: ad_storage, ad_user_data, ad_personalization, and analytics_storage. Since March 2024, it's mandatory for Google Ads in the EEA.

The debugger loads your website in a real browser and checks: whether gtag.js or GTM is present, if consent default is set before tags fire, whether all four GCM v2 consent types are configured, if defaults are set to "denied" for GDPR compliance, if wait_for_update is configured, and whether consent updates fire after user interaction.

Yes, completely free with no sign-up required. You can check any public website up to 5 times per hour.

Since March 2024, Google requires Consent Mode v2 for any website using Google Ads, Google Analytics, or other Google marketing products in the EEA. Without it, you lose remarketing audiences, conversion measurement, and may face reduced ad performance.

The easiest way is to use a CMP like CookieBoss that includes Google Consent Mode v2 built-in on all plans. CookieBoss automatically sets consent defaults, fires consent updates on user interaction, and includes all required GCM v2 consent types — zero configuration needed.
